Foreword
The Rice Inspection Handbook sets forth the policies and procedures for sampling,
inspecting, and certifying rice in accordance with the regulations under the Agricultural
Marketing Act (AMA) of 1946, as amended. These regulations establish the basic
guidelines for inspecting rice and authorize the issuance of such additional guidelines
as may be necessary for the interpretation and application of the United States
Standards for Rice.
The information contained in this handbook is applicable to official rice inspection
services performed by the Federal Grain Inspection Service (FGIS)—a program under
the Agricultural Marketing Service (AMS)—an agency or department of the Federal
Government that has an interagency agreement, a State Agency, or other entity that
has an agreement with FGIS to conduct commodity inspection services under the AMA.
Persons interested in obtaining official services may contact any FGIS field office or
cooperator.

1.8 NEW ORIGINAL INSPECTIONS
a. When the identity of the lot has been lost and /or circumstances prevent a
retest, an appeal, or a Board appeal inspection, an applicant may request
a new original inspection on any previously inspected lot. However, a new
original inspection must not be performed on an identifiable rice lot that, as
a result of a previous inspection, was found to be contaminated with filth
or to contain a deleterious substance.
Note: Identity is not lost if the identity of the rice, carrier, or
container is not lost. A new original inspection cannot be performed
on the same identified lot of rice, carrier, or container in the same
assigned area of responsibility within 5 business days after the last
official inspection.
b. A certificate issued as a result of a new original inspection is, in fact, an
original inspection certificate. It must be based on a new sample and
must not be restricted to the scope of any previous inspection.

1.10 REGISTERED TYPE AND TYPE SAMPLE INSPECTIONS
Registered Type Sample Inspections.
a. Applicants may request that the quality of rice in a lot be compared with
the quality of an identified rice type sample that has been registered with
an FGIS field office or cooperator.
When a registered type sample inspection is requested, the applicant
must follow the below procedure:
(1) Submit a clearly identified rice sample for an inspection for quality
or other criteria:
(a) The sample must not be less than 1,200 grams for milled
rice, 1,800 grams for brown rice for processing, and 2,300
grams for rough rice.
(b) Official personnel may require a larger sample if portions are
to be sent to other offices, or if the applicant requests that
the sample be divided into several portions for submission to
prospective buyers or brokers.
(2) If FGIS is requested to forward registered type sample(s) to
prospective buyers or brokers, the applicant must supply the
necessary containers and labels for samples to be shipped.
(3) Specify, in writing, all pertinent information, including the following:
(a) Identification of the type sample (e.g., Corkin Rice Mills type
“Aunt Carolina Brand” or Duncan Rice Mill type 311); and
(b) Quality factor information or any other criteria information
that is desired.
b. Official personnel must follow the below procedure:
(1) Perform a quality inspection as specified by the applicant and
approved by the FGIS field office or cooperator;
(2) Issue a submitted sample inspection certificate;
(3) Register the type sample in the field office or office of the
cooperator; and
Rice Inspection Handbook
Chapter 1: General Information
August 2020
1-20
(4) Retain a representative portion of the type sample, under
refrigeration, for comparison with the sample(s) obtained from
identified lot(s).
(a) Because of limited refrigerated storage and file space, and
the possibility of quality factor change due to prolonged
storage, type samples will not be retained for more than 1
year from the submitted sample inspection certificate
issuance date.
(b) Notify the applicant of record at least 30 days prior to the
expiration date of the type sample; and
(c) Destroy the type sample on the expiration date.
(5) When requested by the applicant, send a copy of the submitted
sample inspection certificate and a sample of the rice to the BAR,
other FGIS field offices, or cooperator offices that have been
requested to compare the quality of an identified lot of rice against
the type sample.
(6) If the applicant requests that one or more representative portions
be divided out from the type sample for submission to prospective
buyers or brokers, securely seal each representative portion in a
plastic bag that has a label affixed.
Show the following information on the label:
(a) The statement, “This representative portion of rice was taken
from type sample (sample identification) and was inspected,
registered, and sealed by the (USDA, FGIS, or name of
cooperator).”
(b) Office of inspection (city and state).
(c) Applicant (name, city, and state).
(d) Registration date (date).
(e) Expiration date (date).

(7) Issue a lot inspection certificate when the quality of an identified lot
of rice is compared against the type sample. State that the quality
of the rice in the lot was either “equal to or better than” or “not equal
to” the type sample.
For Example: “(Type of rice/grade and kind of rice). (Quality
equal to or better than/Quality not equal to)
(name of registered type sample).”
Type Sample Inspections. “Type” samples are samples of rice (not officially
sampled) obtained by an applicant and sent to prospective buyers to
demonstrate product quality or analyze for conformance to a prospective buyer’s
standards. The quantity is identified as the entire lot.
For Example: A 5-pound bag of Long Grain Milled Rice represents itself, a
5-pound bag of Long Grain Milled Rice.
Issuing Certificates. Issue an appropriate Submitted Sample Inspection
Certificate as follows:
a. “Identification” section, show the identification of the sample provided by
the applicant;
b. “Quantity” section, enter total weight (grams/pounds) of type sample; and
c. “REMARKS” section, identify the sample as a “Type” sample.

1.11 GRADE OPTIONS
a. Applicants for inspection may obtain “Option 1” or “Option 2” certification
by requesting it on the application for inspection. The request must be
filed prior to the beginning of the inspection.
(1) Under “Option 1,” rice offered for inspection is certified as a specific
grade (e.g., “U.S. No. 2 Long Grain Rough Rice”).
(2) Under “Option 2,” rice offered for inspection would be certified as
being a specific grade “or better” (e.g., “U.S. No. 3 or better Long
Grain Rough Rice”). (Not available for submitted samples.)
Note: If no request for either option is submitted prior to the
beginning of inspection, certification must be “Option 1.”
1.12 OTHERWISE GRADE INSPECTIONS
a. Applicants may request information as to what the quality of rice in a lot or
sample would “otherwise grade” if the results of one or more factors were
not considered.
b. When requested, official personnel must follow the below procedure:
(1) Determine and show the actual grade of the lot or sample in the
space provided for the grade designation; or determine requested
factors only and show the type or class of the rice on the grade line
(e.g., “Milled Rice”).
(2) Show the grade determining factor results and the results of other
analyses in the factor information space.
(3) Show the following statement in the “REMARKS” section of the
certificate:
“(Desired grade and kind) except for (factor(s) that prevent
the lot or sample from being assigned the desired grade).”
c. The following are examples of otherwise grade designations:
Rice Inspection Handbook
Chapter 1: General Information
August 2020
1-23
EXAMPLE 1: An application is received to inspect a lot of U.S. No.
3 Long Grain Milled Rice. The inspection determines
that the rice is U.S. No. 4 Long Grain Milled Rice
because of 17.0 percent total broken kernels.
Grade Designation. “U.S. No. 4 Long Grain Milled Rice.”
Statement. “U.S. No. 3 Long Grain Milled Rice except for total broken
kernels.”
EXAMPLE 2: An application is received to inspect a lot of U.S. No.
3 Long Grain Milled Rice. The inspection determines
that the rice is of the class Mixed Milled Rice because
of 18.9 percent other types.
Grade Designation. “U.S. No. 3 Mixed Milled Rice. Long grain whole
kernels 72.0 percent, medium grain whole kernels 12.9 percent, long grain
broken kernels 9.0 percent, medium or short grain broken kernels 6.0
percent, and seeds 0.1 percent.”
Statement. “U.S. No. 3 Long Grain Milled Rice except for other types.”
EXAMPLE 3: An application is received to inspect a lot of U.S. No.
5 Long Grain Milled Rice. The inspection determines
that the rice is U.S. Sample Grade Long Grain Milled
Rice because of 57.4 percent total broken kernels.
The applicant does not want U.S. Sample Grade to be
shown on the grade line. The factor results meet the
grade limits for U.S. No. 3 Second Head Milled Rice.
Grade Designation. “Milled Rice.”

1.13 ORIGIN INSPECTIONS
a. Applicants may request that origin inspection certificates be issued which
show that their rice is a product of the soil and industry of the United
States.
b. When an origin inspection is requested, official personnel must follow the
below procedure:
(1) Request from the applicant all relevant records that may indicate
the origin of the rice;
(2) Obtain a representative sample; and
(3) Analyze the sample to verify that the rice compares favorably with
types of rice known to be grown in the United States. The
length/width ratios, size, shape, and other kernel characteristics
should be considered in making this determination.
c. If after reviewing the relevant records and analyzing the rice, there is no
indication that the rice is not a product of the soil and industry of the
United States, show the following statement on the certificate:
“The rice described herein and relevant records indicating the origin
of the rice have been examined, and the rice is found to be a
product of the soil and industry of the United States.”
d. When records are not available or if the records are not sufficient to
substantiate that the rice is a product of the soil and industry of the United
States, but the representative sample appears to be of a type of rice
common to the United States, the following statement may be shown on
the certificate:
“Applicant states that this rice is a product of the soil and industry of
the United States.”

1.14 COMBINED-LOT INSPECTIONS
a. Applicants may request a combined-lot inspection to be performed on
single lots of rice during loading, unloading, at rest, or after officially
inspecting and certifying rice as two or more single lots.
b. Requests for service must be in writing and include the following:
(1) The estimated quantity of rice that is to be certified as one lot;
(2) The contract grade, if applicable;
(3) The identity of each carrier into which the rice is being loaded or
from which the rice is being unloaded; and
(4) Any other relevant information that official personnel require.
Note: For recertification of single lots as a combined-lot, the
request for service must be filed no later than two business
days after the latest inspection date of the single lots.
c. Rice in two or more carriers that are to be officially inspected as a
combined-lot must be sampled in a reasonably continuous operation.
Representative samples must be obtained from the rice in each individual
carrier and inspected in accordance with the procedures as prescribed in
Chapter 2, Sampling, of this handbook.
d. Rice that has been officially inspected and certified as two or more single
lots may be recertified as a combined-lot if the following criteria is met:
(1) The rice in each single lot was sampled in a reasonably continuous
operation;
(2) The original inspection certificates issued for the single lots have
been voided by official personnel;
(3) Representative file samples of the single lots are available;
(4) The rice in the single lots is of one grade and quality;
(5) Official personnel who performed the inspection service for the
single lots and those who are to recertify the rice as a combined-lot,
determine that the samples used as a basis for the inspection of the
rice in the single lots were representative at the time of sampling
and have not changed in quality or condition; and

Chapter 1: General Information
August 2020
1-26
(6) The quality or condition of the rice meets uniformity requirements
established by Chapter 2, Sampling, of this handbook.
e. Official factor and official criteria information shown on a certificate for rice
in a combined-lot must be based on the weighted or mathematical
averages of the analysis of the sublots in the lot and must be determined
in accordance with the procedures shown in Chapter 7, Round-Lot
Inspection Plan, of this handbook.
f. If rice in a combined-lot is offered for official inspection as it is being
loaded aboard a carrier and the rice, or a portion of the rice, in a lot is
found to be infested, the applicant must be notified and given one of the
following options:
(1) Removing the infested rice from the lot;
(2) Receiving a grade certificate with a special grade or sample grade
designation, as appropriate, indicating that the entire lot is infested;
or
(3) For rough rice, fumigating the rice in accordance with FGIS
instructions and receiving a grade certificate without the special
grade designation.
g. Samples obtained from rice officially inspected as a combined-lot must be
examined for uniformity of quality. If the rice in the samples is found to be
uniform in quality and the rice is loaded aboard or is unloaded from the
carriers in a reasonably continuous operation, the rice in the combined-lot
must be officially inspected and certified as one lot. The requirements of
this paragraph, with respect to reasonably continuous loading or
unloading, do not apply to rice which is at rest in carriers when the rice is
offered for inspection.
h. When rice officially inspected as a combined-lot is found to be not uniform
in quality or if the rice is not loaded or unloaded in a reasonably
continuous operation, the rice in each portion, and any rice which is
loaded or unloaded at different times, must be officially sampled,
inspected, graded, and certified as single lots.
i. Each official certificate for a combined-lot inspection service must show
the identification for the “combined-lot” or, at the request of the applicant,

(3) The class of rice must be recorded on the grade line of the work
record and the official certificate. The type may be recorded on the
grade line upon request. (e.g., “Milled Rice” or “Long Grain Milled
Rice.”) A numerical grade will not be assigned on the grade line of
the certificate. Factors must be recorded on the work record and in
the “RESULTS” section on the official certificate.
Note: If a Submitted Sample does not contain a sufficient
amount of rice to perform an accurate and complete analysis
for an official grade, the request will be dismissed or a factor
only inspection may be performed upon request.

1.16 WITHHOLDING AND WITHDRAWAL OF AMA INSPECTION SERVICES
Procedures. Section 868.24 of the regulations under the AMA, provides for the
conditional withholding of inspection service for correctable causes, which can be
found in section 868.21, such as (1) failure to pay bills for inspection services, (2)
unsanitary plant conditions, or (3) plant conditions which would subject the
inspector to unusual hazard or discomfort.
a. Inspectors at the plant must report any such conditions to the field office or
cooperator as soon as possible.
(1) The final decision to withhold service must be made by the field
office manager or the cooperator manager.
(2) The field office manager or the cooperator manager may
conditionally withhold service upon notification to the applicant.
b. Section 868.25 of the regulations provides for the denial or withdrawal of
service due to (1) a willful violation of the AMA, regulations, or directives;
or (2) intimidation, threat, assault, or other improper action that interferes
with or obstructs official personnel in the performance of their duties.
(1) Denial or withdrawal of service requires that the applicant be
accorded due process and must, therefore be conducted by FGIS
headquarters in accordance with the Rules of Practice Governing
Formal Adjudicatory Proceedings Instituted by the Secretary of
Agriculture under Various Statutes (7 CFR Part 1, Subpart H).
(2) When circumstances warrant denial or withdrawal of service, the
field office manager or cooperator manager must report the
circumstances in accordance with FGIS Directive 9070.6,
“Reporting Violations of the U.S. Grain Standards Act, and The
Agricultural Marketing Act of 1946.”
Note: If a situation, such as assault, occurs that threatens the
safety of official personnel and also is a violation of the AMA,
the field office managers and cooperator managers may
withhold service on the grounds that official personnel are
subject to hazardous conditions. Such situations should be
reported in accordance with FGIS Directive 9070.6, “Reporting
Violations of the U.S. Grain Standards Act & the Agricultural
Marketing Act of 1946.”

2.1 SAFETY
The safety requirements referenced in this section are mandatory for official
personnel
1
.
a. General. Comply with all FGIS safety requirements and the AMS Safety
Handbook, as well as all pertinent Occupational Safety and Health
Administration (OSHA) requirements (e.g., 29 CFR 1910-60).
(1) Obey all posted warning signs and wear appropriate protective
equipment when conditions warrant (e.g., hard hats and dust
masks).
(2) When necessary and practical, carry a communication device (e.g.,
two-way radio for communication).
(3) Before sampling railcars, check to see if a fall assessment is
required, in accordance with FGIS Directive 9170.14, “FGIS Rolling
Stock Fall Protections.” FGIS employees must complete Fall
Hazard Awareness Training in accordance with the directive. The
requirements of this directive apply to FGIS employees only.
Official Agencies may adopt this policy or use it as a guideline to
establish their own policy to comply with local and national safety
requirements.
b. Life Vests. Wear a U.S. Coast Guard approved Type I, II, III, or V PFD life
vest while aboard barges, launch boats, or other vessels (midstream or
dockside). Before putting on the life vest, inspect it for any potential
defects and to ensure proper fit.
Note: Life vests must be international orange in color, must contain
reflective panels, and must not be of an inflatable type. If used at
night, the vests must be equipped with a light and a whistle.
1
The requirements referenced in this section are mandatory for FGIS employees. All other are strongly
encouraged to also follow these guidelines.
Rice Inspection Handbook
Chapter 2: Sampling
August 2020
2-4
c. Clothing.
(1) Wear hard hats that meet the American National Standards
Institutes (ANSI) Z89.1 or Z89.2 criteria.
(2) Wear shoes or boots that have nonslip soles and definite heels for
good footing on ladders.
(3) Wear clothes that are reasonably close fitting to reduce the
possibility of becoming snagged on ladders or other structural
elements.
(4) Wear gloves when climbing ladders and opening or closing hatches
and doors.
Note: FGIS personnel must follow the clothing requirements
found in FGIS Directive 4735.2, “Uniform and Identity Apparel
and Dress Code Policy.”
d. Gangways and Ladders. Check the gangway before boarding or
disembarking barges and other vessels. Do not use defective gangways.
Exercise extreme care when using ladders that are permanently affixed to
the carrier wall. Do not hand carry sampling equipment, radios, or other
equipment while climbing ladders.
e. Chemical Treatments. Remain alert to your physical condition, especially
when drawing samples inside carriers. Rice is sometimes treated with
chemicals, usually for the purpose of controlling insect infestation.
Contact with toxic fumes or sprays from these chemicals can cause
serious injury or death. The following symptoms can be indicative of a
dangerous atmosphere:
(1) Shortness of breath;
(2) Light- headedness;
(3) Drowsiness; and
(4) Headache.
When any of the above symptoms are experienced, leave the area
immediately and seek medical attention.

f. Transportation.
(1) Travel to and from barges at midstream and other vessels at
anchor via U.S. Coast Guard-approved launch, tugboat, licensed
water taxi, or by Federal Aviation Administration-approved
helicopter or air taxi.
(2) Do not jump on or off a barge or other vessel. You must be able to
step easily from the launch to the vessel (or vessel to the launch)
without stretching or straining over water; expect slippery or
obstructed deck conditions when boarding a vessel.
g. Dock Areas.
(1) While walking on a dock or wharf, be alert for loose or rotting
boards that may not support your weight.
(2) Learn the locations of life rings, emergency ladders, and
telephones.
(3) Stay clear of cables whether slack or under tension.
h. Boats, Barges, and Ships.
(1) FGIS employees must not board any launch boat service to board
any ships, barges, or floating rigs unless a licensed boat captain
and deckhand are present on board the launch vessel. Before
boarding the ship, barge, or floating rig, ensure that the deckhand is
nearby and ready to provide aid in an emergency.
(2) If the launch boat is not staffed with at least one captain and one
deckhand, inform the driver that you are unable to board for safety
reasons and contact your supervisor for further assistance. Upon
boarding the launch boat, familiarize yourself with the location of
any lifesaving devices and request instruction from the captain or
deckhand as to the proper use of such equipment.
(3) Do not probe sample barges at night unless the barge is docked
and sufficient artificial light is provided. Use caution when walking
on decks and barge tops since they are uneven, slippery when wet,
and have protruding cleats and latches. Do not remain on barges
while they are being moved and be aware of nearby barges, docks,
or vessels which could collide with the barge you are working on.
Do not permit hatches to be opened or closed while you are inside
the barge.

i. Trucks.
(1) Do not walk through a break in a string of trucks separated by only
a few feet.
(2) Be alert to such hazards as moving trucks, cables, debris, metal
strapping, or broken ladders.
(3) Avoid breathing diesel exhaust fumes.
j. Railcars.
(1) Before entering a railyard, notify your immediate supervisor, the
yardmaster, or switch-crew foreman, and any other essential
persons of your presence. Do not sample railcars in a railyard
alone unless you are being monitored by someone who is in a
position to render aid if needed. (e.g., One of the two persons that
must be present may be an elevator employee.) Inquire about
possible switching activities, cars carrying hazardous cargo, and
any other unusual activity.
(2) Require that all activity cease on the track where they are working.
Require the track to be locked out, or derails installed at both ends
of the string of cars, or other appropriate, locally-approved
precautions (e.g., using blue flags with radio communication
between you and the switch engine driver, using one or more
additional employees as a safety observer to warn off approaching
railcars, or using blue flags and a lockout switch on an elevator hold
track where no railcar or switch engine movement takes place
during the performance of official functions).
(3) Do not probe sample railcars at night unless adequate artificial light
is provided. Do not walk on the rails; walk parallel to the set of
tracks and never between the two rails. Ensure that no power lines
are close enough to present a hazard (minimum safe distance - 25
feet vertically and horizontally).
(4) Check for placarded railcars. If a car is placarded or if a car is not
placarded and a fumigant odor is detected, withhold the inspection
(do not enter the car or sample the rice) and notify your supervisor
immediately.
Rice Inspection Handbook
Chapter 2: Sampling
August 2020
2-7
(5) Never crawl under railcars. Avoid climbing through railcars and
over couplings and never walk through a break in a string of railcars
separated by only a few feet (minimum safe distance - 20 feet). Be
alert to such hazards as moving railcars, cables, debris along
tracks, metal strapping, or broken ladders hanging from railcars.
(6) Be alert to seasonal conditions, such as icy walking surfaces in the
winter, and rodents, snakes, scorpions, wasps, and hornets in the
warmer months.
(7) Exercise caution when opening or closing car hatches or doors. If
a hatch or door is stuck, request assistance from the applicant.
Use a cutting tool or pry bar to break seals; do not use your hands.
(8) Do not ride on an engine or car being moved or switched. If a car
starts to move while you are on or inside, assume a sitting or
kneeling position on top of or in the car to avoid losing your
balance, and hold on. Do not attempt to descend a ladder or jump
to the ground until the car has stopped and you can do so safely.
Report all incidents of car movement to the yardmaster and your
supervisor. (Supervisors should also report such movements to
either OSHA or the Federal Railroad Administration.)
(9) Notify the yardmaster (or foreman) when you leave the work area
and report all “bad order cars” (e.g., missing ladder rungs, broken
doors) to the car owner, the railroad, or the applicant for inspection.
k. Warehouses. Watch out for forklifts and tow-motors. Also, be alert for
bags slipping (falling) from improperly stacked pallets and overhead
conveyor belts.

2.2 REPRESENTATIVE SAMPLE
Obtaining a representative sample from a lot of rice is an important and essential
part of the rice inspection process. If the sample is not representative, the
inspector’s final determination will not reflect the true quality of the lot. For a
sample to be considered representative, it must be the following:
a. Obtained by official personnel in accordance with official procedures;
b. Obtained using FGIS-approved equipment (see the FGIS Equipment
Handbook);
c. Of the prescribed size (3,000 grams or more for rough rice and brown rice
for processing, and 1,500 grams or more for milled rice); and
d. Handled securely and protected from manipulation, substitution, and
careless handling.
2.3 DETAILED WORK RECORD
a. The accurate recording of the lot’s identity and its condition at the time of
sampling is essential to the correct certification of the lot’s quality.
Samplers must record all unusual conditions and other pertinent
information on FGIS-919, FGIS-992, or other applicable forms. If the
condition is not reported on the detailed work record, the lot could be
inadvertently graded incorrectly.
b. Detailed work records must contain the following information:
(1) The sampler’s signature or initials;
(2) The date the sample was obtained;
(3) The location of the lot of rice at the time of sampling (if the city and/
or state in which the sampling took place is not obvious, this must
also be shown);
(4) Full identification of the lot;
(5) When applicable, information related to the condition of the carrier’s
storage area; and
(6) Any other pertinent information that may affect the grading or
certification of the lot.
Rice Inspection Handbook
Chapter 2: Sampling

c. The original or copy of the work record must be retained by the issuing
office in accordance with the Files Maintenance and Records Disposition
Handbook.

2.4 CARRIER, CONTAINER, AND LOT IDENTIFICATION
a. Official Lots. Carrier, container, lot, and seal identification may be shown
on lot inspection certificates.
Care should be taken to ensure that the proper identification information is
recorded. For lot inspections, official personnel must obtain identification
information personally. Do not transcribe the information from the
application or other documents supplied by the applicant or others.
Obtain identifying information as follows:
(1) Oceangoing vessel identification must be taken from the vessel hull
or obtained from the vessel master or representative.
(2) Barge identification must be taken from the hull, not from
removable tops.
(3) Railcar identification must be taken from the side of the car, not
from the ends.
Note: In certain instances, it may be necessary to separately
certify the rice in one or more compartments of a hopper car
because of different class, quality, or condition.
In such instances, the first bay, or compartment at the car’s
brake end, should be identified as “B-1,” and the remaining
compartments or bays should be numbered consecutively
towards the car’s non-brake end. A statement identifying the
compartment must be shown after the car initials and number,
and it should be followed by the seal identification applied to
the compartment, if applicable.
(4) Truck (without trailer(s)) identification may be taken from a state
license plate or other truck identification. In the case of a truck
which cannot be sealed, the truck identification need not be shown.
If a truck cannot be sealed and if requested by the applicant, the
truck may be identified by other identification, such as load number,
scale ticket number, or other information which will facilitate the
identification of individual trucks.
Rice Inspection Handbook
Chapter 2: Sampling
August 2020
2-11
(5) Truck trailer identification may be taken from a state license plate
on the trailer or other trailer identification. In the case of a trailer
which cannot be sealed, the trailer identification need not be
shown. If a trailer cannot be sealed and if requested by the
applicant, the trailer may be identified by other identification, such
as load number, scale ticket number, or other information which will
facilitate the identification of individual trailers.
(6) Container (e.g., ocean containers, containerized unit loads, or
piggy-back loads) identification must be taken from the front of the
container. The identification number consists of four letters
followed by five or six numbers. The last letter or number, after the
number which is separated by a dash, blank space, or surrounded
by a box may be disregarded.
For Example: If “SEAU12345-9” is printed on the container,
the identification would be “SEAU12345,”
unless the applicant requested that the “-9” be
shown.
(7) Storage bin identification may be taken from information shown on
the bin or from other reliable sources (e.g., warehouse receipt
number).
(8) Warehouse lot identification must be taken from the schematic
layout of the warehouse or from other reliable sources (e.g.,
warehouse receipt number).
b. Submitted Lots. A submitted sample may be identified by the applicant by
sample number, producer’s name, letters of the alphabet, or any other
identification, including a lot or carrier identifier. If a submitted sample is
not adequately identified, the inspector may assign a number to the
sample or request the applicant to assign a number or other identifier to
the sample.
Note: Identification cannot reference the weight or quantity of the
lot.
Rice Inspection Handbook
Chapter 2: Sampling
August 2020
2-12
2.5 ACCESSIBILITY
a. To obtain a representative sample, the entire lot must be completely and
safely accessible.
Note: Labor and equipment necessary for making a lot accessible
must be furnished by the applicant.
(1) If a lot is not completely accessible for sampling, dismiss the
request for service or, at the applicant’s request, sample that
portion that is accessible and issue a “partial inspection” certificate.
(2) When a “partial inspection” is requested, make notations on the
work record indicating the total number of containers in the lot and
the number of containers that were accessible for sampling and
state “PARTIAL INSPECTION”.
For Example: There are 1,263 containers in a lot, but only
400 containers are accessible.
The sampler’s ticket should read the following:
“Sample represents 400 containers only; balance of containers
inaccessible for sampling; total containers in pile 1,263.”
b. For the purpose of sampling bagged rice stored in a warehouse or similar
facility, the lot will be considered accessible when a minimum of one side
of each pallet in the lot is accessible for sampling.
(1) Not every bag in the lot has to be exposed and accessible for
sampling.
(2) It is the sampler’s prerogative to request any or all bags in the lot to
be made accessible for sampling should there be any reason to
suspect that the lot is not uniform in quality.
(3) The following are some examples of when the sampler should
suspect that a lot may not be uniform:
(a) Weathered, dirty, wet, or sour smelling bags mixed in a lot of
clean bags. These bags may contain rice of lower quality.
(b) Bags with different markings. This could indicate the mixing
of bags from another lot which had different quality
requirements.
Rice Inspection Handbook
Chapter 2: Sampling
August 2020
2-13
(c) Bags that appear to have trier penetration marks may have
been previously sampled, graded, and found to be of lower
quality.
c. When the entire lot is not accessible, or a representative sample cannot
be obtained official personnel can conduct a partial inspection of the
accessible portion. The work record and the certificate must indicate that
the inspection is limited to the accessible portion and conspicuously show
in the “REMARKS” section the words “PARTIAL INSPECTION.” An
inspection will be considered a partial inspection when the following
conditions are met:
(1) Bulk rice in bins and shipholds are sampled by a 12-foot bulk probe
that does not reach the bottom of the lot. Show the following
statement “Top feet sampled. Bottom not sampled.” On the
work record and in the “REMARKS” section of the certificate.
Note: Do not issue a partial inspection certificate for bulk rice
in hopper cars or barges that are sampled using the approved
length probe (see section 2.13(a)) that does not reach the
bottom of the lot when fully inserted.
The following statement must be shown on the work record
and in the “REMARKS” section of the certificate:
“Top feet sampled. Bottom not sampled.”
(2) Bulk or bagged rice is offered for inspection at rest in a container
and is loaded in such a manner that it is possible to secure only a
door-probe, mustow-probe, door-bag-probe, or surface-bag-probe
sample(s) of the lot, or the rice is not trimmed, or otherwise does
not have a reasonably level surface, the carrier or container will be
considered to be “heavily loaded” and a partial inspection certificate
issued.
For the purpose of this handbook, the following terms must have
the following meanings:
(a) Door-Probe Sample. A sample taken with an approved
probe from a bulk rice lot which is loaded so close to the top
of the carrier or container, that it is possible to insert the
probe only in the rice in the vicinity of the door or hatch of
the carrier or area in the container in which the rice is
located.
Rice Inspection Handbook
Chapter 2: Sampling
August 2020
2-14
(b) Mustow-Probe Sample. A sample taken with an approved
probe from a bulk rice lot which is loaded so close to the top
of the carrier or container, that it is possible to insert the
probe in the rice at the prescribed locations, but only at an
angle greater than the angle prescribed in the handbook.
(c) Door-Bag-Probe Sample. A sample taken with an approved
trier from a bagged rice lot which is loaded so close to the
top of the carrier, that it is possible to insert the trier only in
the rice bags in the vicinity of the door or hatch of the carrier
or area in the container in which the bags are located.
(d) Surface-Bag-Probe Sample. A sample taken with an
approved trier from a bagged rice lot which is loaded or
placed, that it is possible to insert the trier only in the rice in
the bags in the upper portion, sides, or ends of the lot.
d. If a partial inspection is made, the rice must be sampled as thoroughly as
possible with an approved trier or probe. The work record and the
inspection certificate issued must have the words “PARTIAL
INSPECTION” conspicuously shown in the “REMARKS” section of the
certificate.
(a) In addition, the work record and the certificate must show the
type of sample(s) obtained. The type of sample(s) will be
described as “door-probe,” “mustow-probe,” “door-bag-
probe,” or “surface-bag-probe” samples will be shown in the
“REMARKS” section of the certificate.
(b) In the case of packaged rice (including bagged rice), the
approximate number of containers accessible for sampling
and the approximate number of containers in the lot must be
shown on the work record and in the “REMARKS” section of
the certificate. (e.g., “800/100-pound polypropylene bags,
part of an undivided lot of 1,250 bags.”)

2.6 SAMPLE HANDLING AND SECURITY
a. A representative sample must never be out of the control and/or
observation of the sampler. Special care must always be taken to protect
samples from manipulation, substitution, and improper handling. There
are many ways in which a sample may lose its representativeness. For
example, a sample will no longer be considered representative if it is:
(1) Spilled, no matter how little is lost or how much is recovered;
(2) Stored in an improper manner or in an area, not under the control
of official personnel; or
Note: When samples are not analyzed on the same day they
are obtained, store them in a cool, dry place to prevent any
change in condition.
(3) Transported by means which do not ensure the integrity of the
sample.
Note: Official samples may be shipped via U.S. mail or
commercial parcel service, provided that the samples are
delivered directly to official personnel and all other necessary
security precautions are taken. Such precautions may include
securing the sample with an official numbered seal if
warranted.
b. Lockboxes or other security containers must be provided by the applicant
at plants where official services are performed on a continuing basis. The
lockboxes must be:
(1) Of sufficient size to contain samples, sampling supplies and
equipment, and checkweighing scales (it is not intended that items
such as dividers and probes be stored in the lockbox); and
(2) Placed in the immediate work area (lockboxes must not be placed
in the basement or in any other remote locations). If it is impossible
or impractical to locate the lockboxes in the immediate sampling
area, a portable locked container, such as a locked metal pail,
should be used; and
(3) Equipped with a hasp for a padlock (padlocks must be provided by
official personnel and, under no circumstances, will keys to the
padlocks be issued to or made accessible to unauthorized
persons).

2.7 PLANT SANITATION EXAMINATIONS
2
a. Official personnel must examine or survey rice plants for unsanitary
conditions when:
(1) Required by federal law or purchase contract;
(2) Required by FGIS Program Directive;
(3) Requested by the applicant for inspection; or
(4) Deemed necessary by official personnel.
b. Unsanitary conditions include those conditions that, in the opinion of
official personnel, would render the rice unfit for human consumption, but
which may not be adequately reflected by the grade assigned to the rice.
Unsanitary conditions include, but not be limited to, the presence of the
following:
(1) Vermin or insects;
(2) Toxic substances;
(3) Decayed animal or vegetable matter;
(4) Other filth; and
(5) Harmful substances, such as broken glass and metal shavings.
c. If the plant is approved, services may begin or continue at a time agreed
upon by plant management and official personnel.
d. If the plant is not approved, official inspection services must be
conditionally withheld pursuant to the procedures in Section 868.24 of the
regulations under the AMA, the FGIS Sanitation and Food Defense
Handbook, and FGIS Directive 9100.3, “Withholding and Withdrawal of
AMA Inspection Services.”
2
The premises, buildings, structures, and equipment (including but not limited to machines, utensils,
vehicles, and fixtures located in or about the premises) used or employed in the preparation, processing,
holding, transporting, and storage of rice. Establishments engaged only in the harvesting, storage, or
distribution of rice prior to the rice being cleaned, shelled, milled, or otherwise processed for human
consumption are not considered as “plants” for the purpose of this handbook.
Rice Inspection Handbook
Chapter 2: Sampling
August 2020

2.8 EXAMINATION OF FILLED CONTAINERS
a. Official personnel must examine filled containers to determine if the rice
being offered for inspection may have been contaminated or may become
contaminated as a result of the condition of the container.
b. Filled container examinations include checking the containers, such as
burlap, jute, cotton, paper, or polypropylene bags; cases; or bales to
determine whether they are free from dirt, stains, tears, live or dead
insects, insect webbing, and insect refuse.
c. If adverse conditions are found, note the conditions, kind of containers,
and all container markings on the work record and in the “REMARKS”
section of the certificate.
Rice Inspection Handbook
Chapter 2: Sampling
August 2020
2-18
2.9 CONTAINER MARKINGS INFORMATION
Most packaged rice has identifying marks on the containers. These marks are
required to be shown on the rice inspection certificate if the marks indicate a
different quality of rice than what is actually in the container. All other times, the
markings may be shown upon request of the applicant. Show such markings on
the work record and certificates as follows:
a. Uniform Markings.
(1) When container markings are uniform for an identified rice lot, then
all markings may be shown on the work record and the certificate.
Some markings shown on the containers, identify the container
manufacturer and/or some other container specification, and does
not serve any useful purpose with regard to identifying marks. Such
information does not need to be shown as identifying marks, unless
requested by the applicant.
(2) Markings are usually shown in lines one above the other, as
follows:
RICE
PRODUCT OF U.S.A.
EXTRA FANCY
LONG GRAIN
888
SAM, INC.
STUTTGART, AR
Space permitting, such markings may be shown on the work record
and the certificate as shown above but are usually shown with
slash marks indicating the end of each line of markings, as follows:
RICE/PRODUCT OF U.S.A./EXTRA FANCY/LONG GRAIN/888/
SAM, INC./STUTTGART, AR
b. Nonuniform Markings.
(1) On some occasions, an identified rice lot will have varied markings
shown on the containers. Such markings are usually the result of
the use of “leftover” containers accumulated and used by a shipper
at the end of a shipping season.
Rice Inspection Handbook
Chapter 2: Sampling
August 2020
2-19
(2) When such marks are found and the applicant does not request
that such marks be shown, the statement “No Common Marks” may
be shown in the space provided for remarks on the work record and
on the certificate.
(3) If the applicant requests that such varied markings be shown, the
applicant has the responsibility of separating the containers by the
various markings so that the number of containers of each marking
can be determined, or the applicant can furnish the count.
c. Nonuniform Markings - With Uniform Sublot Markings.
(1) There are occasions when several sublots, with uniform markings
within each sublot but varying markings from each other, will be
accumulated in warehouses and designated as one overall lot.
(2) In such instances, a record will be kept of the number of bags of
each set of uniform markings contained within the overall lot. Such
information may be shown in the space provided for remarks on the
work record and on the certificate.
For Example: An identified warehouse lot consisting of 10
separate cars (1,200 100-pound bags each)
was unloaded on a warehouse floor. Six of the
carlots have one set of uniform markingsm,
and four of the carlots have another set of
uniform markings.
The certificate (with regard to markings) would be issued
substantially as follows:
7,200 bags marked: RICE/Product of U.S.A./Jones Rice
Co./Eunice, LA/(Reverse) LARENCO MARQUES
4,800 bags marked: RICE/Product of U.S.A./Smith Rice
Inc./Houston, TX/ (Reverse) LARENCO MARQUES
d. Tag Markings. When containers are tagged with identifying markings, the
tag information may be shown in the space provided for remarks on the
work record and on the certificate as follows:
EXPORT/RICE/SOUTH AFRICA/LONG GRAIN
Rice Inspection Handbook
Chapter 2: Sampling
August 2020
2-20
e. Contract Specification Markings. An applicant may request that the
markings be checked only for compliance with contract specifications. In
such cases, show on the work record and in the “REMARKS” section of
the certificate, one of the following statements:
(1) “Bag markings as specified by (contract number, agency, or other
pertinent information).”
(2) “Bag markings not as specified by (contract number, agency, or
other pertinent information) because (reason (e.g., code number
omitted or letter size incorrect)).”
f. Registered Trademark Markings.
(1) Many rice companies, exporters, and shippers have registered
trademarks (brand names) for rice packaged by or for them. Such
markings may contain artwork, such as an eagle, crossed rifles, a
plantation home, and many other markings which frequently are not
necessary, practicable, or requested by the applicant.
(2) When such instances occur and all of the brand name information
is not needed or requested by the applicant, the brand name may
only be shown in parenthesis followed, if necessary, by any export
marks shown on the reverse of the bag. In such cases, show on
the work record and in the “REMARKS” section of the certificate as
follows:

2.10 EXAMINATION OF CARRIERS (STOWAGE EXAMS)
a. When rice is to be sampled during loading, examine the carrier prior to
loading for conditions that could adversely affect the quality of the rice.
(See FGIS Directive 9180.48, “Stowage Examinations.”) Adverse
conditions include, but are not limited to, the presence of the following:
(1) Live insect infestation or other injurious insects;
(2) Odors of previously transported cargoes;
(3) Water;
(4) Previous cargo;
(5) Decaying animal or vegetable matter;
(6) Protruding objects which may damage the containers;
(7) Holes in the carrier’s roof, sides, doors, or floor; and
(8) Rust scale, dirt, chemicals, and unknown substances.
b. Record the results of the examination on a stowage examination
worksheet, sampling ticket, FGIS-911, inspection log, general service
worksheet, or other work record.
c. If no adverse conditions are found, sampling/loading may begin or
continue at a time agreed upon by the plant management and official
personnel.
d. If adverse conditions are found, official inspection service will be
conditionally withheld pursuant to the procedures in Section 868.24 of the
regulations under the AMA.
e. In lieu of removing rust scale from lash or other types of barges that are to
be loaded with bagged rice, a woven polyethylene liner may be used to
cover the walls and floors.
(1) If a liner is installed, verify that the rust scale is effectively covered
and show the following statement on the work record and in the
“REMARKS” section of the certificate:
“Woven polyethylene liner installed in barge in lieu of
removing rust scale.”
Rice Inspection Handbook
Chapter 2: Sampling
August 2020
2-22
(2) Bulk rice offered for official inspection may not be loaded into
carriers that have woven polyethylene liners covering either the
bottom or the side of the carrier, because such liners may tear and
contaminate the rice. However, bulk rice may be loaded into
standard intermodal containers and truck trailers that contain
polyethylene disposable bag-type liners. (Stowage exam must be
performed prior to the liner/bag being installed).
f. When rice is sampled after loading, examine the accessible portions of the
carrier and note any adverse conditions on the work record and in the
“REMARKS” section of the certificate.
Note: For rice lots, stowage examinations on river barges are not
allowed from the main deck. You must enter all carriers (except bulk
hopper cars and bulk hopper trucks) when stowage examinations are
performed for rice.
Note: Stowage examinations are not required for outbound domestic
railcar shipments of rice that are sampled at the time of loading, if:
(1) the applicant for inspection, with the mutual agreement of all
interested parties, request that a stowage examination not be
performed; and (2) official personnel verify that the railcars’ previous
cargo was the same type of rice to be loaded and is not ‘out of
condition’.

2.11 FACILITY EXAM
a. When rice is to be loaded at a bulk loading facility, examine the delivery
system to ensure the rice to be loaded will not be adversely affected by
the condition of the loadout system. A facility exam is ONLY required
when sampling bulk rice during movement. The facility examination
should include any areas of the facility that will come in direct contact with
the rice or present conditions that could potentially cause the quality of the
rice to be adversely affected (e.g., pit, elevators legs, boot, conveyor
system, the entire length of the belt(s)). If the facility uses a pit that trucks
drive over to offload, the approaches must be maintained as to not allow
anything to enter the pit that will adversely affect the quality of the rice
(e.g., rock, mud, water, glass).
Note: The belt should be allowed to run a full cycle to confirm the
belt is clean, dry, and free of debris and damage (rips, tears,
excessive fraying, etc.). It is not recommended to have the spout in
the carrier when the belt is running during this part of the exam
Adverse conditions include, but are not limited to, the presence of the
following:
(1) Live or dead insect infestation or other injurious insects;
(2) Odors of previously loaded cargoes;
(3) Water;
(4) Previous cargo;
(5) Decaying animal or vegetable matter; and
(6) Dirt, chemicals, and unknown substances.
b. Record the results, the date and time the exam was completed on the
work record.
(1) If no adverse conditions are found, sampling/loading may begin or
continue at a time agreed upon by the plant management and
official personnel. Show the following statement in the “REMARKS”
section of the certificate:
“The bulk loading facility was examined on (date) at (military
time) and found to be clean, dry, free of insect infestation,
and suitable to maintain the quality of the (type of rice).”
Rice Inspection Handbook
Chapter 2: Sampling
August 2020
2-24
c. If adverse conditions are found, official inspection service may be
conditionally withheld until conditions are corrected. Show the following
statement in the “REMARKS” section of the certificate:
“The bulk loading facility was examined on (date) at (military time)
and found not suitable to maintain the quality of the (type of rice).
d. This service is not mandatory may be requested by the applicant.
2.12 EXAMINATION OF SAMPLE PORTIONS
Compare each sample portion taken from a lot of rice with other sample portions
drawn from the same lot for uniformity of type/class, quality, and condition.
a. If all sample portions are uniform, composite the portions together.
b. If any sample portion is considered to be of distinctly different type/class,
quality, or condition from the remainder of the sample portions, draw
separate samples from the portion of the lot that contains the distinctly
different rice, the remainder of the lot, and the entire lot. Keep the
samples in separate containers and note on the respective work records
the estimated quantity of the lot represented by each sample.

Note: For lots packed in primary and secondary containers, the number of secondary
(outer) containers in the lot must be used to determine the number of containers to be
sampled.
1
If the lot contains more than 10,000 containers, divide the lot into 2 or more (approximately)
equal sized sublots of 10,000 containers or less. Sample and grade each sublot separately.
b. Draw a sample from each selected container using either an approved rice
bag trier (see “List of Approved Equipment,” in the FGIS Equipment
Handbook) of sufficient length to reach the center of the container, a
compartmented probe of sufficient length to reach the bottom of the
container, or a ladle.
(1) When sampling rice in large-sized containers (22.5 kilograms/50
Pounds or more):
(a) For closed containers, use a 29.5-centimeter (11 5/8-inch)
rice bag trier for brown rice or milled rice, and a 40.6-
centimeter (16-inch) rice bag trier for rough rice. A 99-
centimeter (39-inch) compartmented probe may also be
used for any type of rice.
(b) For open containers, use a 99-centimeter (39-inch)
compartmented probe or a ladle.
(2) For sampling rice in medium-sized containers (4.5 to 22.4
kilograms/10 to 49.9 pounds):
(a) For closed containers, use a 29.5-centimeter (11 5/8-inch)
rice bag trier for brown rice or milled rice, and a 40.6-
centimeter (16-inch) rice bag trier for rough rice.
(b) For open containers, use a ladle.
(3) For sampling rice in small-sized containers (4.5 kilograms/10
pounds or less), use a ladle or take the entire contents of selected
containers.
c. The procedures for drawing a sample with a rice bag trier are as follows:
(1) Insert the trier into the bag.
Rice Inspection Handbook
Chapter 2: Sampling
August 2020
2-27
(2) Give the inserted trier two or three short in-and-out motions to allow
a free flow of rice through the trier into a sample container.
(3) Examine the sampled rice for uniformity of type/class, quality, and
condition. If uniform, combine the rice with other rice of equal
quality from the same lot, sublot, or component.
Note: Close all trier holes made during sampling.
d. Draw a sample with a compartmented probe as follows:
(1) Stand the container on end and insert the probe into the top of the
container.
(2) Move the probe diagonally through the container until the end of the
probe touches the bottom corner opposite the top corner from
which it was inserted.
(3) Open the probe with the slots facing upward.
(4) While the slots are open, give the probe two or three short up-and-
down motions so that the compartments in the probe can be filled.
(5) Close the probe gently to avoid damaging the rice, withdraw the
probe, and place its contents full length on a sampling cloth.
(6) Examine the sampled rice for uniformity of type/class, quality, and
condition. If uniform, combine the rice with other rice of equal
quality from the same lot, sublot, or component.
e. The procedures for drawing a sample with a ladle are as follows:
(1) Dip the ladle into the open container before it is sealed.
(2) Pour the sample into a sample pan.
(3) Examine the sampled rice for uniformity of type/class, quality, and
condition. If uniform, combine the rice with other rice of equal
quality from the same lot, sublot, or component.
f. After samples have been taken from a lot offered for inspection, the
applicant is responsible for closing all open containers from which
samples have been drawn and replacing containers taken as samples. If
the applicant does not replace the containers that were removed or
properly seal the containers which were left open, note on the work record
the number of whole/sealed containers remaining after sampling.

g. When rice in containers is sampled during movement (online), draw a
sample from one of the first five containers that are packed, a sample from
one of the last five containers, and the remaining samples at random
intervals during the packing of the lot.

b. Sample bulk rice at rest in a carrier as follows:
(1) Visually examine the lot of rice at rest in the carrier. Record any
unusual conditions on the work record.
(2) Spread your tarp and make sure that it and the probe are clean and
dry.
(3) For each type of carrier there is an established sampling pattern
(see section 2.13(c)). Probe the rice in the areas identified by the
sampling pattern for the particular carrier.
Note: At the discretion of the cooperator or Field Office
manager or Cooperator manager, non-licensed personnel may
assist official personnel in obtaining samples, provided that:
(1) all non-licensed personnel are under the direct, physical
supervision of official personnel at all times; (2) the ratio of
official personnel to non-licensed personnel is reasonable and
practical; and (3) official personnel determine the general
condition of the commodity and whether additional samples
are needed due to quality differences.
(4) Insert the probe at a 10-degree angle from the vertical, completely
closed.
Rice Inspection Handbook
Chapter 2: Sampling
August 2020
2-30
(5) If the rice contains fine debris (e.g., dockage, fine broken kernels) it
is permissible to insert the probe with the slots facing downward to
avoid “freezing” the probe. After the probe is inserted, turn the slots
upward before opening. After the probe is fully inserted (with the
slots facing upward), open the slots and move the probe up and
down quickly in short motions until windows are mostly filled.
(6) Close the slots gently so as not to damage the rice (a slight
opening between the slots and the probe is allowable). Grasp the
probe by the outer tube and withdraw it from the rice. Do not pull
the probe by the handle.
(7) Empty the probe on the tarp and compare the rice from each depth
of the probe for uniformity of type/class, quality, and condition. Also
compare the sample portion to others drawn from the same lot. If
all sample portions are uniform, they must be composited and
placed in a sample bag along with a completed work record.
Sample tarp size must be proper length (at least as long as the
probe).
Note: If the probe does not reach the bottom of the carrier,
show the following on the work record:
“Top (depth reached) feet sampled, BNS.”
c. The following figures indicate the standard sampling patterns. Each lot
must be probed in as many additional locations as are necessary to
assure that the sample is the required size and representative of the lot.
Additional probes must be drawn in a balanced (proportional) manner.
The sampling patterns in this section must be used by all official
inspection personnel when sampling rice at rest. Insert the probe at the
points marked (X), with the tip of the probe pointed toward the direction of
the arrowhead. When two arrow heads are shown, the tip of the probe
may be pointed in either direction.

d. Sample bulk rice at rest in bins and elevators by inserting the probe into
the rice through exterior inspection holes/doors. Record the following
statement on the work record:
“Sample represents an estimated (amount) only. Balance of bin
inaccessible for sampling; total amount in bin estimated (amount).”
Caution: Do not enter closed bins.
e. Sample bulk rice in flat storage facilities/warehouses in as many places as
practicable, but in no less than five locations.
f. Sample bulk rice in “tote” bags (e.g., large flexible containers holding 500-
3000 pounds of rice) as follows:
(1) Lots of 1 Bag. Draw no less than five probes from the tote.
(2) Lots of 2 to 4 Bags. Draw at least two probes from each tote but no
less than six probe samples from the entire lot. Always draw the
same number of probe samples from each bag.
(3) Lots of 5 to 9 Bags. Draw at least one probe sample from each
bag, but always draw the same number of probe samples from
each bag
(4) Lots of 10 to 30 Bags. Draw no less than ten probe samples from
the entire lots. Randomly select the bags to be probed and draw
no more than one probe sample from each selected bag.
(5) Lots of 31 or More Bags. Draw one probe sample from at least 25
percent of the bags or ten probe samples from the entire lot,
whichever is greater.

2.15 SAMPLING BULK RICE DURING MOVEMENT
3
a. FGIS tested and approved diverter-type mechanical samplers (D/T) may
be used to sample bulk rice during movement. (See the FGIS Mechanical
Sampling Systems Handbook for testing and approval information.)
(1) Prior to using a D/T, ensure that the system is clean and free of rice
or debris from a previous shipment.
(2) For sampling rice as it is being placed in bags or similar containers,
set the D/T counter switch so that the pelican will traverse the
stream at least once every 25 containers.
(3) For sampling rice being loaded into bulk carriers, set the timer in
accordance with prescribed procedures.
b. FGIS tested and approved Woodside-type mechanical samplers may be
used to sample bulk rice during movement. (See the Mechanical
Sampling Systems Handbook for testing and approval information.)
FIGURE 2.7 - WOODSIDE-TYPE MECHANICAL SAMPLER

c. FGIS-approved pelican samplers may be used to sample rice in a falling
stream.
FIGURE 2.8 – PELICAN SAMPLER
Draw a sample using a pelican sampler as follows:
(1) Grasp the pelican’s handle firmly.
(2) Then, swing the pelican completely through the stream in one
continuous motion. This is known as taking a “cut.”
The following is the minimum number of “cuts” required:
Hopper Car
2 cuts per carrier
Boxcar
4 cuts per carrier
Truck
2 cuts per carrier
Hopper Truck
2 cuts per carrier
Barge/Ship
(30,000 lbs.)
1 cut per 13,500 kilograms
Caution: Sampling a free-falling stream of rice with a pelican
sampler can be dangerous. Assure yourself of firm, nonskid
footing. Retrieval lines may be attached to the handle of the
pelican and to the carrier. Do not tie the line to a person.
Rice Inspection Handbook
Chapter 2: Sampling
August 2020
2-37
d. FGIS-approved Ellis cup samplers may be used for sampling rice moving
on a conveyor belt.
FIGURE 2.9 – ELLIS CUP SAMPLER
Draw a sample using the Ellis cup as follows:
(1) Hold the Ellis cup firmly and upright, with the sides of the cup
parallel to the sides of the conveyor belt, and with the open end of
the cup facing the oncoming flow of rice.
(2) Push the curved portion of the cup straight down in the center of
the stream to the full depth of the rice. After filling, withdraw the
cup and empty it.
(3) Then, immediately draw two more portions from the stream; one to
the left of center and one to the right of center. This is known as
taking a “set” of samples.
Note: When drawing samples with an Ellis cup from rice in a
narrow stream or on a slow-moving conveyor belt, all portions
may be taken from the center of the stream and portions may
be drawn in a delayed manner, as necessary.

1 set per carrier
Barge/Ship
(30,000 lbs.)
1 set per 13,500 kilograms
Caution: Ensure that you have good footing to avoid falling
onto the belt and that a U-shaped protective guard rail is
installed no less than 2-1/2 feet above each belt and secured to
the floor. Retrieval lines may be attached to the handle of the
Ellis Cup and to the guardrail. Do not tie the line to a person.

2.16 UNUSUAL CONDITIONS
Note: If any unusual conditions are detected or suspected, notify your
supervisor as soon as possible.
a. Do not allow yourself to be hurried to the point that the integrity of the
sample is undermined or a condition, such as objectionable odor, insect
infestation, or heating, is overlooked. Remember, obtaining a
representative sample is the most important aspect of a sampler’s job.
b. If you suspect that the quality of the rice in the sample is not indicative of
the true quality of the rice in the lot, draw another representative sample
using a slightly different sampling pattern, a longer probe, or draw an
auxiliary sample.
c. An auxiliary sample is drawn only for the purpose of determining if the lot’s
true condition is indicated by the representative sample.
(1) An auxiliary sample is used to “backup” the representative sample,
not as another representative sample. For example, if you suspect
that a hopper car containing rice is contaminated with fertilizer,
even though no fertilizer was present in the probe sample, draw an
auxiliary sample.
(2) Auxiliary samples may be obtained in any safe manner that is
effective in obtaining a sample from the portion of the lot that is
suspected of being contaminated or of being a distinctly different
quality than the remainder of the lot (e.g., in a hopper car), an
unusually long probe may be used or a well may be dug so that the
bottom of the carrier can be reached.
(3) If an unusual condition is found in an auxiliary sample, identify the
auxiliary sample with a separate work record(s) and submit the
auxiliary sample along with the representative sample.
(4) The identification should indicate the specific location in the lot
where the auxiliary sample was drawn.
Example: “Auxiliary Sample, N&W 176186,
Compartment B-1.”
Note: Do not mix the auxiliary sample with the representative
sample.
d. If you observe any of the following conditions in a lot, a representative
sample, or an auxiliary sample, report the condition on the work record(s).
Rice Inspection Handbook
Chapter 2: Sampling
August 2020
2-40
(1) Angoumois Moths. If moths are found flying or crawling around the
lot or the carrier, record an estimate of the number observed.
(2) Infestation. If weevils, grain borers, insect larvae, bran bugs, or
other insects injurious to stored rice are found on, around, or about
the lot, note the number, type, and location where observed.
Note: To aid in insect identification, refer to FGIS Visual
Reference Images (VRI) and/or the FGIS Stored-Grain Insect
Reference.
(3) Large Debris and Other Sample Grade Factors. If any of the
following conditions are observed in a lot, record the amount, size,
number (whichever is more applicable) and the location where
found:
(a) Large stones, large sticks, cement;
(b) Pieces of metal, glass, or fertilizer;
(c) Rodent or bird excreta;
(d) Castor beans, crotalaria seeds, treated seeds;
(e) Lumps of rice, grain, dirt and/or other commodities, unknown
foreign substance, toxic material, or unnatural Odors
(COFO); and
(f) Any material too large to enter a probe, Ellis cup, pelican DT
sampler or any official sampling device.
(4) Heating Rice. When high temperatures develop in rice as the result
of excessive respiration, such rice is called “heating.” Heating rice
usually gives off a sour or musty odor.
(a) Note the location and quantity on the sample ticket.
(b) Do not confuse heating rice with rice that is warm due to
storage in bins, cars, or other receptacles during warm
weather.
(5) Distinct Differences in Quality or Other Unusual Conditions.
Describe the condition in detail on the sample ticket.
Rice Inspection Handbook
Chapter 2: Sampling
August 2020
2-41
(6) Odors. Odors should be detected on the original sample at the
time of sampling.
(a) When an Agricultural Commodity Grader (ACG) is not
available, immediately place the suspect sample into an
airtight container for transport to the laboratory for an
examination by an ACG.
(b) Musty and sour odors are the result of mold growth or
fermentation.
(c) Commercially objectionable foreign odors are the result of
absorption by rice of residual odors from previous cargo, oil,
and other material. See Table 2.3 – Odor Classification
Chart for a list of these and other odors that may be found in
rice.

3.1 DEFINITION OF ROUGH RICE
Rough Rice. Rice (Oryza sativa L.) which consists of 50 percent or more of
paddy kernels of rice.
Paddy Kernels. Whole or broken unhulled kernels of rice.
a. Paddy kernels are usually determined by cursory examination of the work
sample as a whole.
b. When a detailed examination is necessary, determine paddy kernels on a
representative portion of no less than 50 grams of rough rice before the
removal of dockage.
(1) Record the percentage of paddy kernels on the work record to the
nearest tenth percent.
(2) If the rice contains less than 50 percent of paddy kernels, consider
the rice to be brown rice for processing and refer to Chapter 4,
Brown Rice, for additional information.
Note: Rice that does not meet the United States Standards for
Rough Rice, Brown Rice for Processing, or Milled Rice will be
determined “Not Standardized Rice.”

3.4 WORK RECORD
Record the results of all tests and findings clearly and accurately on a sample
ticket or similar form. This will be used as the source of the information reported
on the inspection certificate. FGIS personnel must use FGIS-911, “Rice Sample
Ticket,” to record inspection results. Cooperators must use a similar form.
3.5 REPRESENTATIVE PORTION
A specified quantity of rice divided-out from the representative sample by means
of an FGIS approved divider.
3.6 WORK SAMPLE
A representative portion of rice (approximate size - 1,000 grams) that is used to
make all such determinations required for a particular class of rice.
Note: A Submitted Sample of rough rice with a request for grade that does
not contain 1,000 grams or more will be dismissed; or a factor only
inspection may be performed upon request.
3.7 FILE SAMPLE
a. A representative portion of rice (approximate size - 1,500 grams) that may
be used in conjunction with the work sample, when needed, to determine
the complete grade. File samples may also be used for monitoring, retest,
and appeal inspection purposes.
b. Retain file samples in appropriate containers for the required retention
period. After maintaining for the required period, dispose of the file
samples in accordance with established procedures. See FGIS Directive
9170.13, “Uniform File Sample Retention System” for additional
information.

3.8 PERCENTAGES AND COUNTS
a. Basis of Determination. Percentages are determined upon the basis of
weight and are rounded as follows:
(1) When the figure to be rounded is followed by a figure greater than
or equal to 5, round to the next higher figure (e.g., report 6.36 as
6.4, 0.35 as 0.4, and as 2.5).
(2) When the figure to be rounded is followed by a figure less than 5,
retain the figure (e.g., report 8.34 as 8.3, and 1.22 as 1.2).
b. Record percentages as follows:
(1) For milling yield, in tenths of a percent (unrounded) in “RESULTS”
section of the work record and to the nearest whole percent
(rounded from the nearest tenth) on the grade line of the certificate.
(e.g., 66.56 is reported as 66.5 in the results section on the work
record and in the results section and reported as 67 on the grade
line of the certificate).
(2) For all other factors, to the nearest tenth percent.
c. Record counts, for all factors determined on the basis of count, to the
nearest whole number.

3.10 PRELIMINARY EXAMINATION
a. The sampler must: (1) observe the uniformity of the rice as to type/class,
quality, and condition; (2) make the determination for “Heating”; (3) draw
the representative sample; and (4) report relevant information to the
inspector.
b. The inspector must review the sampler’s remarks/information. If the
inspector has questions or doubts the representativeness of the sample,
he or she must contact the sampler and obtain the needed information or
make arrangements to obtain another sample.
Rice Inspection Handbook
Chapter 3: Rough Rice
August 2020
3-10
3.11 BASIS OF DETERMINATION
Certain Quality Determinations. The determination of seeds, objectionable
seeds, heat-damaged kernels, red rice and damaged kernels, chalky kernels,
other types, color and the special grade Parboiled rough rice must be on the
basis of the whole and large broken kernels of milled rice that are produced in
the milling of rough rice to a well-milled degree.
Class. When determining class, the percentage of (A) whole kernels of rough
rice must be determined on the basis of the original sample, and (B) types of rice
must be determined on the basis of the whole and large broken kernels of milled
rice that are produced in the milling of rough rice to a well-milled degree.
Smutty Kernels. Smutty kernels must be determined on the basis of the rough
rice after it has been cleaned and shelled as prescribed in FGIS instructions or
by any method that is approved by the Administrator as giving equivalent results.
All Other Determinations. All other determinations must be on the basis of the
original sample. Mechanical sizing of kernels must be adjusted by handpicking
as prescribed in FGIS instructions, or by any method that is approved by the
Service as giving equivalent results.
Note: When rice that is offered for inspection as one lot is found to contain
more than 10,000 containers (packaged/bags/balers) or 6,000,000 pounds
(bulk) of rice, the lot must be sampled on the basis of two or more
(approximately) equal-sized sublots of 10,000 containers
(packaged/bags/balers) or 6,000,000 pounds or less. Inspect each sublot
separately. (For additional information, see Chapter 7, Roundlot Inspection
Plan and Chapter 9, Warehouse-Lot Inspection Plan.)
Note: When rice that is offered for inspection as one lot is subsequently
found to contain portions that are distinctly different in class/type, quality,
or condition, the rice in each portion must be inspected separately.
a. Follow a systematic grading procedure. The order of procedure may vary
depending on the class and the quality of the rice and the tests that are
required to determine the grade. A general order of procedure is as
follows:
(1) Review the information on the work record.
(2) Examine the representative sample for odor and distinctly low
quality.
Rice Inspection Handbook
Chapter 3: Rough Rice
August 2020
3-11
(3) Use an FGIS-approved divider to process the representative
sample into three representative portions: (a) a work portion, (b) a
file portion, and (c) a moisture portion.
Note: For specific information on the operation and
maintenance of dividers, see the FGIS Equipment Handbook,
Chapter 7, Manual Sampling Devices.
(4) Examine the work sample for the following:
(a) Class;
(b) Paddy kernels (if necessary);
(c) Type;
(d) Infestation; and
(e) Test weight (if requested).
(5) Remove the dockage from the work sample and, upon request,
determine the percentage of dockage.
(6) Also, upon request, examine the dockage-free portion for gold and
straw colored kernels.
(7) Shell the dockage free portion and examine the shelled rice portion
for smutty kernels.
(8) Mill the shelled rice portion. After cooling to room temperature,
determine total milled rice (milling yield).
(a) Examine the milled rice for odor.
(b) Upon request, determine the milling yield (whole kernels and
total milled rice).
1 Divide out from the milled rice portion a 40-gram
portion and determine whole kernels (milling yield).
2 Examine the whole and large broken kernels portion
for color.
3 Divide the whole and large broken kernels portion to
500 grams and examine the portion for the following:
Rice Inspection Handbook
Chapter 3: Rough Rice
August 2020
3-12
a Seeds;
b Heat-damaged kernels; and
c Ungelatinized kernels in parboiled rice.
(c) Divide the 500-gram portion to 25 grams and examine the
portion for the following:
1 Chalky kernels;
2 Red rice and damaged kernels; and
3 Other types
b. When the grade of a lot or sample is determined by a narrow margin (+/-
0.1 percent or 1 count) on a single factor, except for the factors seeds and
heat-damaged kernels on non-cargo lots, another determination must be
made on another representative portion of equivalent size divided out from
the work sample or file sample. The factor result must be based on the
average of the two determinations.
Note: Narrow margin determinations do not apply to multiple lots
where tolerance is applied.

3.12 MOISTURE
Water content in rough rice as determined by an approved device in accordance
with according to procedures prescribed in FGIS instructions.
Note: Rough rice will not be milled when the moisture content exceeds
18.0 percent.
a. Basis of Determination. Determine moisture on a representative portion of
sufficient size of rough rice before the removal of dockage as described in
the Moisture Handbook.
b. Procedures. The procedures for performing a moisture determination
using the FGIS approved moisture meters are described in the Moisture
Handbook.
c. Record the percentage of moisture on the work record and in the
“RESULTS” section of the certificate to the nearest tenth percent. If the
moisture content exceeds 14.0 percent, grade the rice “U.S. Sample
Grade.”

3.13 TYPE
There are three types of rough rice: (1) Long grain, (2) Medium grain, and (3)
Short grain.
Types must be based on the length-width ratio of kernels of rice that are
unbroken and the width, thickness, and shape of kernels of rice that are broken,
as prescribed in FGIS instructions.
FIGURE 3.1 – EXAMPLE CALCULATION OF LENGTH/WIDTH RATIO
The length-width ratio limitations for rough rice are as follows in Table 3.3 –
Length-width Ratio Limitations:
TABLE 3.3 – LENGTH-WIDTH RATIO LIMITATIONS
Long grain
Medium grain
Short grain
3.4 (or more) to 1
2.3 - 3.3 to 1
2.2 (or less) to 1
a. Type is usually determined by a cursory examination of the work sample
as a whole.
b. When a detailed examination is necessary, measure the length and width
of 15 unbroken kernels of rough rice taken at random from the work
sample and determine their average length-width ratio.
(1) For awnless kernels, length is the straight-line distance from the
outer glumes to the tip of the lemma. For kernels with an awn,
length is the straight-line distance from the outer glumes to the
base of the awn.

3.14 CLASS
a. There are four classes of Rough rice: (1) Long Grain Rough Rice, (2)
Medium Grain Rough Rice, (3) Short Grain Rough Rice, and (4) Mixed
Rough Rice.
Classes must be based on the percentage of whole kernels, large broken
kernels, and types of rice.
(1) Long Grain Rough Rice. Long Grain rough rice must consist of
rough rice which contains more than 25 percent of whole kernels
and which after milling to a well-milled degree, contains no more
than 10 percent of whole or large broken kernels of medium or
short grain rice.
(2) Medium Grain Rough Rice. Medium Grain rough rice must consist
of rough rice which contains more than 25 percent of whole kernels
and which after milling to a well-milled degree, contains no more
than 10 percent of whole or large broken kernels of long grain rice
or whole kernels of short grain rice.
(3) Short Grain Rough Rice. Short Grain rough rice must consist of
rough rice which contains more than 25 percent of whole kernels
and which, after milling to a well-milled degree, contains no more
than 10 percent of whole or large broken kernels of long grain rice
or whole kernels of medium grain rice.
(4) Mixed Rough Rice. Mixed rough rice must consist of rough rice
which contains more than 25 percent of whole kernels and which,
after milling to a well-milled degree, contains more than 10 percent
of “other types” as defined in section 3.30, “Other Types,” of this
chapter.
b. Class is usually determined by a cursory examination of the work sample
as a whole.
c. When a detailed examination is necessary to determine whole kernels for
class, make this determination on a representative portion of no less than
40 grams of rough rice before the removal of dockage.
(1) Record the percentage of whole kernels on the work record to the
nearest tenth percent.
(2) If the rice contains 25 percent or less of whole kernels, show the
designation “Rough Rice” on the grade line of the certificate. Do
not show either a class or grade designation on the certificate.
Rice Inspection Handbook
Chapter 3: Rough Rice
August 2020
3-17
d. When a detailed examination is necessary to determine other types for
class, make this determination on a representative portion of no less than
25 grams of whole and large broken kernels of well-milled rough rice.
(1) Record the percentage of each type on the work record to the
nearest tenth percent.
(2) Grade the rice “Mixed Rough Rice,” if the rice contains more than
10 percent of the following:
(a) Whole or large broken kernels of medium or short grain rice
in long grain rice;
(b) Whole and large broken kernels of long grain rice or whole
kernels of short grain rice in medium grain rice; or
(c) Whole or large broken kernels of long grain rice or whole
kernels of medium grain rice in short grain rice.
e. Determine the percentage of material removed by the No. 6 sieve or the
No. 6 sizing plate, and when applicable, the percentage of seeds.
Record the percentage of whole kernels of each type present in the order
of predominance; the percentage of large broken kernels of each type
present in order of predominance; and when applicable, the percentage of
material removed by the No. 6 sieve or the No. 6 plate and the percentage
of seeds to the nearest tenth percent on the work record and in the
“RESULTS” section of the certificate. (These percentages must total
100%.)
Note: Large broken kernels other than long grain in Mixed Rough
Rice must be certified as “medium or short grain.”
Rice Inspection Handbook
Chapter 3: Rough Rice
August 2020
3-18
3.15 ODOR
a. Determine odor on the basis of a representative portion of well-milled
rough rice. Upon request, a non-grade odor determination may be made
on the basis of the rough rice, as is.
Off-odors (i.e., musty, sour, and commercially objectionable foreign odor)
can sometimes be detected when smelling the rough rice at the time of
sampling.
Note: If there is any question as to the odor when the sample is
being taken, note on the work record and put that portion of the
sample into an airtight container to preserve its condition for further
examination. The final odor determination is made in the laboratory.
b. The final odor determination must be made on the sample after milling to a
well-milled degree.
(1) A musty odor is any odor that is earthy, moldy, or ground-like. Do
not confuse a burlap bag odor with a musty odor.
(2) A sour odor is any odor that is rancid, sharp, or acrid.
(3) A commercially objectionable foreign odor is any odor that is not
normal to rice and that, because of its presence, renders the rice
unfit for normal commercial usage (e.g., fertilizer, hides, oil
products, skunk, smoke, fire-burnt, decaying animal, and vegetable
matter odors).
(4) Fumigants or insecticide odors are not considered as commercially
objectionable foreign odors unless they are caused by a fumigant
or insecticide that does not dissipate quickly. When a sample of
rice contains a fumigant or insecticide odor that prohibits a true
odor determination, the following guidelines must apply:
(a) The representative sample of rice must be allowed to air-out
in an open metal container (e.g., a pan) for up to 4 hours, a
fume hood may be used if available; and
(b) If the fumigant or insecticide odor still prohibits the
determination of the rice’s true odor after 4 hours, the rice
must be considered as having a commercially objectionable
foreign odor.
Rice Inspection Handbook
Chapter 3: Rough Rice
August 2020
3-19
Caution: When sampling rice, check for placarded
railcars. If a car is placarded (or if a car is not placarded
but a fumigant odor is detected), do not enter the car or
sample the rice, and notify your supervisor immediately.
Note: Aromatic (scented) rice that has an odor known to
be common to such rice must be declared at the time of
the inspection request or will be considered as having a
commercially objectionable foreign odor.
c. When rice is determined to be musty, sour, or have a commercially
objectionable foreign odor, record the type of odor on the work record and
in the “RESULTS” section of the certificate, and grade the rice “U.S.
Sample Grade.”
Note: Rough rice found to have a commercially objectionable
foreign odor is considered actionable according to FGIS Directive
9060.2, “Implementation of the FGIS-FDA Memorandum of
Understanding.”

3.16 HEATING
a. Determine heating on the basis of the lot as a whole.
(1) When high temperature develops in rice as the result of excessive
respiration, such rice is heating.
(2) Heating rice usually gives off a sour or musty odor.
(3) Care should be taken never to confuse rice that is warm due to
storage in bins, cars, or other containers during hot weather with
rice that is heating from excessive respiration.
b. When applicable, show the term “Heating” on the work record and in the
“RESULTS” section of the certificate, and grade the rice “U.S. Sample
Grade.”
Rice Inspection Handbook
Chapter 3: Rough Rice
August 2020
3-21
3.17 DISTINCTLY LOW QUALITY
a. Determine distinctly low quality on the basis of the lot as a whole or the
representative sample as a whole or an auxiliary sample.
b. Rough rice that is obviously affected by unusual conditions which
adversely affect the quality of the rice and which cannot be graded
properly by use of the grading factors specified or defined in the
standards, must be considered as being of distinctly low quality (see Chart
3.1 – Distinctly Low Quality). Rough rice that contains any material too
large to enter a probe, Ellis cup, pelican, DT sampler or any official
sampling device such as pieces of wreckage and debris including lumps of
rice, grain, dirt and/or other commodities, unknown foreign substance or
toxic material which are visible to the sampler is considered DLQ.

3.18 INSECT INFESTATION
a. Infested Rough Rice. Tolerances for live insects for infested rough rice
are defined according to sampling designation as follows:
(1) Representative Sample. The representative sample consists of the
work portion, and the file sample if needed and when available.
The rough rice (except when examined according to paragraph
(a)(3) of this section) will be considered infested if the
representative sample contains two or more live weevils, or one live
weevil and one or more other live insects injurious to stored rice, or
five or more other live insects injurious to stored rice.
(2) Lot as a Whole (Stationary). The lot as a whole is considered
infested when two or more live weevils, or one live weevil and one
or more other live insects injurious to stored rice, or five or more
other live insects injurious to stored rice, or fifteen or more live
Angoumois moths or other live moths injurious to stored rice are
found in, on, or about the lot.
(3) Sample as a Whole During Continuous Loading/Unloading. The
minimum sample size for rice being sampled during continuous
loading/unloading is 500 grams per each 100,000 pounds of rice.
The sample as a whole is considered infested when a component
(as defined in FGIS instructions) contains two or more live weevils,
or one live weevil and one or more other live insects injurious to
stored rice, or five or more other live insects injurious to stored rice.
Note: “Weevils” must include coffee bean weevils, broad-
nosed grain weevils, rice weevils, granary weevils, maize
weevils, and lesser grain borers. “Other live insects injurious
to stored rice” must include beetles, moths, meal worms, and
other insects injurious to stored rice.
Note: To aid in insect identification, refer to FGIS Visual
Reference Images (VRI) and/or the FGIS Stored-Grain Insect
Reference.
b. Determine infestation on the basis of a representative portion of
approximately 1,000 grams, the lot as a whole, and/or a component
sample taken during continuous loading/unloading.
(1) Examine a representative portion.
(a) If no live insect is found in the portion, make no further check
for insects.
Rice Inspection Handbook
Chapter 3: Rough Rice
August 2020
3-23
(b) If two or more live weevils are found, consider the rice to be
“Infested.”
(c) If one live weevil and any other live insect injurious to stored
rice is found, consider the rice to be “Infested.”
(d) If only one live weevil or other insect injurious to stored rice
is found, cut another representative portion of approximately
1,000 grams from the file sample. (Use the rest of the
representative sample if the file sample is less than 1,000
grams.)
1 If one or more live weevils or other live insects
injurious to stored rice are found in the second
portion, consider the rice to be “Infested.”
2 If no live insect is found in the second portion, do not
consider the rice to be “Infested.”
(e) If no live weevil is found, but five or more other live insects
injurious to stored rice are present, consider the rice to be
“Infested.”
(2) Examine the rice in the lot (i.e., the surface area of the lot and the
area around the lot).
(a) If no live insect is found in, on, or about the lot, make no
further check for insects.
(b) If two or more live weevils are found, consider the rice to be
“Infested.”
(c) If one live weevil and any other live insect injurious to stored
rice is found, consider the rice to be “Infested.”
(d) If no live weevil is found, but five or more other live insects
injurious to stored rice are present, consider the rice to be
“Infested.”
(e) If fifteen or more live Angoumois moths or other live moths
are present, consider the rice to be “Infested.”
Rice Inspection Handbook

(3) Examine the component samples
4
taken during continuous
loading/unloading.
(a) Divide out from the component sample a representative
portion of approximately 1,000 grams.
(b) Examine the representative portion for live insects.
1 If no live insect is found in the representative portion,
make no further check for insects.
2 If two or more live weevils are found, consider the rice
to be “Infested.”
3 If one live weevil and any other live insect injurious to
stored rice is found, consider the rice to be “Infested.”
4 If one live weevil and no other insect injurious to
stored rice is found, cut another representative portion
of approximately 1,000 grams from the component
sample.
a If one or more live weevils or other live insects
injurious to stored rice are found in the second
portion, consider the rice to be “Infested.”
b If no live insect is found in the second portion,
do not consider the rice to be “Infested.”
5 If no live weevil is found, but five or more other live
insects injurious to stored rice are present, consider
the rice to be “Infested.”
c. When applicable, show the term “Infested” on the work record and on the
grade line of the certificate.
Note: If a lot of Rough rice was determined to be “Infested”, the lot
may be fumigated to remove the special grade, “Infested” pending
specific fumigation criteria is met. Refer to the Fumigation
Handbook for specific criteria and certification procedures.

a. Determine test weight per bushel on a representative portion of
approximately 1,000 grams of rough rice before the removal of dockage.
b. General Operating Procedures.
(1) Level and balance the test weight per bushel apparatus.
(2) Close the hopper valve.
(3) Pour the work sample into the hopper.
(4) Center the hopper over the kettle.
(5) Fill the kettle by opening the hopper valve quickly.
(6) Move the hopper all the way to the left before proceeding. Do not
jar the apparatus. Jarring could cause inaccurate results.
(7) Using a standard stroker, stroke the kettle by holding the stroker in
both hands with the flat sides in a vertical position. Level the rice in
the kettle by making three full-length, zigzag motions with the
stroker.
(8) Convert the weight of the sample by either the “standard” method
or one of the “alternate” methods.
(a) Standard Method. Carefully hang the kettle on the beam
and move the weights until the beam is balanced. Read the
test weight per bushel scale.
(b) Alternate Method – Manual Conversion. Pour the sample
from the kettle onto a general class scale, note the weight of
the sample, find the gram weight on the test weight
conversion chart (see Appendix 1 in the Grain Inspection
Handbook, Book II, Grading), and read the corresponding
test weight per bushel shown to the right of the gram weight.
Rice Inspection Handbook
Chapter 3: Rough Rice

3-26
(c) Alternate Method – Automatic Conversion. When using an
electronic scale programmed to convert gram weight to
pounds per bushel select the appropriate test weight mode.
Place an empty sample pan or the test weight kettle on the
scale and zero the scale. Pour the sample from the kettle
into the sample pan or place the filled kettle onto the scale
as appropriate. Read the result from the test weight mode
selected.
c. Record the test weight per bushel on the work record to the nearest tenth
of a pound and record in the “RESULTS” section of the certificate.
d. Upon request by the applicant the following statement may be recorded in
the “REMARKS” section of the certificate:
“Test weight per bushel of (amount) pounds is approximately
equivalent to (amount) kilograms per hectoliter.”
Kilograms per hectoliter are determined by multiplying the test weight per
bushel by 1.287.
Note: Bulk density may be determined by dividing the test weight
per bushel by 1.2445. Bulk density is the number of pounds in one
cubic foot.

3.20 DOCKAGE
a. Determine dockage on a representative portion of 1,000 grams of rough
rice. Dockage is all matter other than rice that can be readily removed
from the rough rice by the use of appropriate sieves and cleaning devices.
It may also include underdeveloped, shriveled, and small pieces of kernels
of rough rice that are removed in properly separating the dockage and that
cannot be recovered by properly rescreening or recleaning.
b. Set up the Carter dockage tester as follows:

Note: For Mixed rough rice, use the sieves prescribed for the type of rice that
predominates in the mixture.
c. Adjust the feed hopper of the dockage tester so that during the first run
practically all of the rice will pass through the upper half of the top sieve
before it passes the midpoint of the sieve. Vary the feed adjustment, if
necessary, depending on the class of rice and the amount of dockage in
the rice.
d. Dockage consists of the following:
(1) All material removed by air;
(2) All material (except rice) which goes over the top sieve;
(3) All material (except rice) which goes over the middle sieve; and
(4) All material that goes through the bottom sieve.

3.22 MILLING YIELD
Definition. An estimate of the quantity of whole kernels and total milled rice
(whole and broken kernels combined) that are produced in the milling of rough
rice to a well- milled degree.
Note: Rough rice will not be milled when the moisture content exceeds
18.0 percent.
a. Determine milling yield on a representative portion of 1,000 grams of
rough rice before the removal of dockage.
(1) Divide out a representative portion of between 950 and 1,050
grams.
(2) Add or remove kernels (by finger pinching, not pouring) until the
required portion is obtained.
b. Milling yield is determined by removing the dockage from the
representative portion, shelling the dockage free portion, converting the
shelled rice to milled rice, and then separating the whole kernels from the
total milled rice portion.
(1) Remove the dockage from the rough rice using an FGIS-approved
dockage machine. (See section 3.20, “Dockage,” for further
details.)
(2) Shell the dockage-free rough rice using an FGIS-approved sheller.
(Shelling is the removal of the hulls from the paddy rice.)
(a) Adjust the hopper feed so that between 450 and 500 grams
of rice passes through the sheller per minute.
(b) Adjust the dial setting so the sample contains 2 to 3 percent
paddy kernels in long grain rice or 3 to 4 percent paddy
kernels in medium or short grain rice after shelling. Use the
appropriate dial settings for the approved sheller as per
standardization requirements.
Note: For Mixed Rough Rice, use the setting prescribed
for the type of rice that predominates in the mixture.
(c) Start the sheller and then pour the rice into the sheller.
(d) After all of the rice has cleared the sheller, turn the sheller
off.
Rice Inspection Handbook
Chapter 3: Rough Rice
August 2020
3-31
Note: Pass the rice through the sheller only once.
(3) Mill the shelled rice using an FGIS-approved miller. (Milling is the
removal of practically all of the germ and the bran from the brown
rice.)
(a) If the miller has not been used recently, warm up the miller
as follows:
1 Place approximately 750 grams of milled or brown
rice in the milling chamber with a 2-pound weight on
the weight holder.
2 Make at least three consecutive 30-second runs.
3 Thoroughly clean the miller.
(b) Proceed with the milling of the shelled portion.
1 Set the miller’s timer switch at exactly 30 seconds.
2 Tilt the chamber so that the rice will flow uniformly
beneath the milling cylinder and pour the entire
portion of shelled rice into the milling chamber.
3 Close the milling chamber and return it to the milling
position.
4 Position the saddle and weight arm on the milling
chamber.
5 Position the weight holder on the weight arm.
6 Position the prescribed weight on the weight holder
for the type of rice to be milled.

requirements.
9 Start the miller for the 30-second brushing cycle.
10 After brushing, remove the weights, weight holder,
weight arm, and saddle.
11 Clean the miller and the hopper.
12 Place a container under the hopper opening and
transfer the rice from the milling chamber into the
container. Do not close or seal the container.
13 Allow the sample to cool to room temperature before
removing it from the container.
(c) Examine the rice for milling degree.
In determining milling yield in rough rice, the degree of
milling must be equal to, or better than, that of the Visual
Aid: Well-Milled.
If it is determined that the rice is not equal to or better than
the Visual Aid: Well-Milled, pour the rice back into the miller
and repeat the brushing cycle.
Rice Inspection Handbook
Chapter 3: Rough Rice

(4) Determine the percentage of total milled rice. Total milled rice is
the whole and broken kernels that are produced in the milling of
rough rice to a well-milled degree.
Weigh the rice after milling and divide this weight by the weight of
the rice before the removal of dockage, shelling, and milling.
For Example: The sample of rough rice weighs 1,000 grams
before the removal of dockage, shelling, and
milling. After the removal of dockage, shelling,
and milling, the sample weighs 679 grams.
679 grams ÷ 1,000 grams = 67.9 percent
67.9 percent = 68 percent total milled rice
Record the percentage of total milled rice in tenths of a percent
(unrounded) in “RESULTS” section of the work record and to the
nearest whole percent (rounded from the nearest tenth) on the
grade line of the certificate.
(5) Determine the percentage of whole kernels.
Whole Kernels. Unbroken kernels of rice and broken kernels of rice
which are at least three-fourths of an unbroken kernel. Seeds or
material other than rice are considered broken kernels.
(a) Divide out a representative portion of no less than 40 grams
of well-milled rough rice.
(b) Remove the whole kernels from the well-milled rough rice
portion using any device or method that will facilitate the
separation of the whole kernels from the broken kernels.
(c) Determine the percentage of whole kernels in the 40 gram
portion and then multiply this percentage by the percentage
(unrounded) of total milled rice.
For Example: The 40 gram portion weighed 40.61
grams of well-milled rough rice and
contains 34.51 grams of whole kernels.
(84.9 percent of whole kernels.)
The percentage of total milled rice is 67.9 percent before
rounding.
Rice Inspection Handbook
Chapter 3: Rough Rice
August 2020
3-34
34.51 grams ÷ 40.61 grams = 84.9%
84.9% x 67.9% = 57.6% = 58% whole kernels
Note: Carry out all figures used in the calculations to
tenths of a percent. Do not carry out to hundredths.
(d) Record the percentage of whole kernels in tenths of a
percent (unrounded) in “RESULTS” section of the work
record and to the nearest whole percent (rounded from the
nearest tenth) on the grade line of the certificate.
For Example: U.S. No. 2 Long Grain Rough Rice

3.23 BROKEN KERNELS
Definition. Kernels of rice which are less than three-fourths of whole kernels.
Note: This factor is not provided for under the United States Standards for
Rough Rice but may be determined upon request.
a. Determine broken kernels on a representative portion of no less than 25
grams of well-milled rough rice.
b. Remove the broken kernels from the milled rough rice portion using any
device or method that will facilitate the separation of the broken kernels
from the whole kernels.
c. Record the percentage of broken kernels on the work record and in the
“RESULTS” section of the certificate to the nearest tenth percent.

3.24 LARGE BROKEN KERNELS
Note: This factor is not provided for under the United States Standards for
Rough Rice, but may be determined upon request.
a. Determine large broken kernels on the well-milled rough rice portion as a
whole. Large broken kernels are the broken kernels of rice (including
seeds) removed from the total milled rice sample that will pass over a 6
plate or remain on top of a 6 sieve.
(1) Run the rice over a 6 plate (for Southern production) or a 6 sieve
(for Western production). (See procedures in section 3.25, “Whole
and Large Broken Kernels”.)
(2) Remove all whole kernels from the material that passes over the
plates or remains on top of the sieve. All other rice that passes
over the plates or remains on top of the sieve will be considered as
large broken kernels.
b. Record the percentage of large broken kernels on the work record and in
the “RESULTS” section of the certificate to the nearest tenth percent.
Note: Upon request, one or more of the following may be
determined: (1) the number of seeds, (2) heat-damaged kernels, (3)
the percentage of red rice and damaged kernels, or (4) chalky kernels
in the large broken portion may be determined. Determine these
factors on a representative portion of no less than 25 grams of large
broken kernels of well-milled rough rice. These additional results
would be recorded in the “REMARKS” section of the certificate,
along with the following statement:
“(Factor(s)) was/were based on a portion of no less than 25
grams of large broken kernels of well-milled rough rice.”
Rice Inspection Handbook
Chapter 3: Rough Rice

3-37
3.25 WHOLE AND LARGE BROKEN KERNELS
Definition. Rice (including seeds) that (1) passes over a 6 plate (for southern
production) or (2) remains on top of a 6 sieve (for western production).
Determine whole and large broken kernels on the well-milled rough rice portion
as a whole.
a. For southern production rice:
(1) Place a 6 plate in the top carriage and a 6 plate in the bottom
carriage of the rice sizing device.
(2) Pour the milled rough rice portion on the top plate. After the sample
is poured, place the emptied triangular pan under the hopper to
catch the rice that flows over the plates.
(3) Turn the machine on. Allow the machine to run until the rice stops
flowing over the plates into the triangular pan.
(4) After the rice stops flowing and the machine is turned off, remove
the plates and empty their contents into the rectangular container.
Lightly tap the bottom of the plate(s) to remove material retained in
the perforations of the plate.
(5) Usually one run of the milled rough rice over the plates is sufficient
to remove the 6 plate material. Observe the plates as they are
being emptied. If most of the perforations of the bottom plate are
filled, run the sample over the plates again.
(6) Consider material that passes over the 6 plates after the final run
as whole and large broken kernels.
Note: Do not hand adjust the material that lodges in or passes
over the 6 plate.
b. For western production rice:
(1) Mechanical Sieving Method.
(a) Mount a 6 sieve with a bottom pan on a mechanical sieve
shaker.
(b) Set the stroke counter for 20 strokes.
Rice Inspection Handbook
Chapter 3: Rough Rice
August 2020
3-38
(c) Gently pour the representative portion of about 250 grams of
grain rice in the center of the sieve.
(d) The procedure for operating the mechanical sieve shaker is
as follows:
1 Make sure the shaker is level.
2 Turn the machine on.
3 After the required number of strokes has been
completed, the machine will automatically stop.
4 Carefully remove the sieve and bottom pan. Jarring
the sieve will cause the material remaining on top to
pass through the perforations, leading to inaccurate
results.
5 Combine the material lodged in the perforations with
the material that remained on top of the sieve. To
remove the lodged material from the perforations, rub
the sieve bottom gently. Tapping will warp the sieve
and lead to inaccurate results in future
determinations.
For more specific information on the operation,
maintenance, and performance sieves and sieve
shakers, see Chapter 9, Sieves, of the Equipment
Handbook.
(e) All material remaining on top of the 6 sieve (including the
material remaining in the perforation of the sieve) is
considered whole and large broken kernels.
Note: Do not hand adjust the material that remains of
top of or passes through the 6 sieve.
(f) Pour the remaining sample portion onto the sieve and repeat
the aforementioned procedures.
(2) Hand Sieving Method.
(a) Mount the 6 sieve on a bottom pan.
(b) Place a portion of about 250 grams in the center of the
sieve.
Rice Inspection Handbook
Chapter 3: Rough Rice
August 2020
3-39
(c) Hold the sieve level in both hands with elbows close to the
body. In a steady motion, move the sieve from left to right
approximately 10 inches and return from right to left.
(d) Repeat the sieving operation 20 times.
(e) All the material remaining on top of the 6 sieve (including the
material remaining in the perforations of the sieve) is
considered as whole and large broken kernels.
Note: Do not hand adjust the material that remains on
top of or passes through the 6 sieve.
(f) Pour the remaining sample portion onto the sieve and repeat
the aforementioned procedures.
c. Upon request, record the percentage of whole and large broken kernels
on the work record and in the “RESULTS” section of the certificate to the
nearest tenth percent.
d. When determining milling yield, is it not necessary to return the portion
used in the determination of whole kernels back to the remainder of the
sample before running the sample over the No. 6 sieves.

3.26 HEAT-DAMAGED KERNELS (VRI R-2.0)
Definition. Whole or large broken kernels of rice which are materially discolored
and damaged as a result of heating, and whole or large broken kernels of
parboiled rice in nonparboiled rice which are as dark as, or darker in color than,
the Visual Aid: Heat Damage (VRI R-2.0).
Note: Cold mold kernels are kernels of rice that are discolored by a
storage fungi which ranges from a light to dark amber/brown in color and
can be distinguished from other types of damage or heat damage by its
translucent appearance.. Cold mold would generally function as damage;
however, if the color intensity meets or exceeds that depicted in Visual Aid:
Heat Damage (VRI R-2.0), it would then function as heat damage.
a. Determine heat-damaged kernels on a representative portion of 500
grams of whole and large broken kernels of well-milled rough rice.
(1) Divide out a representative portion of between 475 and 525 grams.
(2) Add or remove kernels (by finger pinching, not pouring) until the
required portion is obtained.
b. When it is determined by general observation that the 500-gram portion
contains 75 or more heat-damaged kernels, divide the 500-gram portion
into two portions: a 100-gram portion and a 400-gram portion.
(1) Examine the 100-gram portion for heat-damaged kernels.
(2) If the 100-gram portion contains 25 or more heat-damaged kernels,
multiply the number of kernels found by 5.
(3) If the 100-gram portion contains less than 25 heat-damaged
kernels, examine the 400-gram portion and add the number of
heat-damaged kernels found in both portions together.
c. If the whole and large broken kernels portion removed from the total milled
rice weighs less than 500 grams, make the determination on the portion
that is available and calculate the number of heat-damaged kernels that
would be present in a 500-gram portion as follows:
(1) Multiply the number of heat-damaged kernels by 500;
(2) Divide the sum by the weight of the whole and large broken kernels
portion; and
(3) Round to the nearest whole number.
Rice Inspection Handbook
Chapter 3: Rough Rice
August 2020

For Example: The number of heat-damaged kernels in the
whole and large broken kernels (WLBK)
portion is 6. The weight of the WLBK portion is
450 grams.
6 HT x 500 grams = 6.6 = 7HT in 500 grams
450 grams WLBK
d. Record the number of heat-damaged kernels on the work record and in
the “RESULTS” section of the certificate to the nearest whole number.
(1) Add the number of heat-damaged kernels to the number of
objectionable seeds and record the sum on the work record and in
the “RESULTS” section of the certificate to the nearest whole
number.
(2) Add the number of heat-damaged kernels to the number of total
seeds and record the sum on the work record and in the

Visual Aid: Objectionable Seeds (VRI R-1.0).
Non Objectionable Seeds. Echinochloa crusgalli (commonly known as barnyard
grass, watergrass, and Japanese millet). Visual Aid: Non Objectionable Seeds
(VRI R-1.2).
a. Determine objectionable seeds and non-objectionable seeds on a
representative portion of 500 grams of whole and large broken kernels of
well-milled rough rice.
(1) Divide out a representative portion of between 475 and 525 grams.
(2) Add or remove kernels (by finger pinching, not pouring) until the
required portion is obtained.
b. If the whole and large broken kernels portion removed from the total milled
rice weighs less than 500 grams, make the determination on the portion
that is available and interpolate the number of seeds that would be
present in a 500-gram portion as follows:
(1) Multiply the number of seeds by 500.
(2) Divide the sum by the weight of the whole and large broken kernels
portion, and round to the nearest whole number.
For Example: The number of seeds in the whole and large
broken kernels (WLBK) portion is 8. The
weight of the WLBK portion is 430 grams.
8 SD x 500 grams = 9.3 or 9 SD in 500 grams
430 grams WLBK
c. Record the number of objectionable seeds and non-objectionable seeds
on the work record.

3.28 RED RICE AND DAMAGED KERNELS
a. Definitions.
(1) Red Rice. Whole or large broken kernels of rice on which there is
an appreciable amount of red bran.
(2) Damaged Kernels. Whole or large broken kernels of rice which are
distinctly discolored or damaged by water, insects, heat, or any
other means, (including whole or large broken kernels of parboiled
rice in non-parboiled rice). “Heat-damaged kernels” must not
function as damaged kernels.
b. Basis of Determination. Determine red rice and damaged kernels on a
representative portion of no less than 25 grams of whole and large broken
kernels of well-milled rough rice.
(1) Red rice is rice that has a streak of red bran one-half or more the
length of the kernel, or two or more streaks that total one-half or
more the length of the kernel.
(2) A kernel or a piece of kernel of rice that does not have sufficient red
bran to be considered as red rice will be considered as long grain,
medium grain, or short grain rice as appropriate.
Note: Black rice would function as red rice. Black rice is rice
that has a streak of black bran one-half or more the length of
the kernel, or two or more streaks that total one-half or more
the length of the kernel. A kernel or piece of a kernel that does
not have sufficient black bran to be considered as red rice will
be considered as long grain, medium grain, or short grain as
appropriate and could function as other types.
c. Types. The major types of damaged kernels are as follows:
(1) Insect-Bored Kernels.
Whole or large broken kernels of rice that have been bored by
insects. Kernels that are only slightly eaten by insects and are
clean in appearance will be considered as sound kernels.

(2) Pecky Kernels Damage (VRI R-2.7) and Water, Stain, and Peck
Damaged (Glutinous Rice) (VRI R-2.71).
Whole or large broken kernels of rice that have one or more black,
brown, red, or other discolored spots or areas on them caused by
fungus growth or insects. Mold is defined as a fungus-growth and
therefore, will be treated as fungus-damaged. Visual Aid: Pecky
Kernels Damage (VRI R-2.7). Visual Aid: Water, Stain, and Peck
Damaged (Glutinous Rice) (VRI R-2.71).
(3) Damaged by Heat (Stain) (VRI R-2.1).
Whole or large broken kernels of rice that are distinctly discolored
to the minimum color intensity illustrated. There is no minimum
coverage requirement. Kernels Damaged by Heat (Stain) are
lighter in color than the Visual Reference Image for heat-damaged
kernels. Visual Aid: Damaged by Heat (Stain) (VRI R-2.1).
Lightly Stained (Not Damage) (VRI R-2.2). Whole or large broken
kernels of rice that are not damaged but have a light discoloration
(stain) equal to or greater than color shown on the VRI. There is no
minimum coverage requirement. Visual Aid: Lightly Stained (Not
Damage) (VRI R-2.2).
Note: Lightly Stained (Not Damage) is not provided for under
the United States Standards for Rough Rice, but may be
determined upon request.
(4) Parboiled Rice in Nonparboiled Rice.
Whole or large broken kernels of Parboiled rice in nonparboiled rice
that are lighter in color than the Visual Aid: Heat Damage (VRI R-
2.0).
(5) Other Damaged Kernels.
Whole or large broken kernels of rice that are distinctly discolored
or damaged from causes other than those listed above will be
considered as damaged kernels.

3.31 COLOR
a. Color is usually determined by a cursory examination of whole and large
broken kernels of well-milled rough rice.
b. When a detailed examination is necessary to determine color, make this
determination on a representative portion of approximately 250 grams of
whole and large broken kernels of well-milled rough rice and the
appropriate Visual Reference Image.
c. Describe the color of the rice using one of the following terms:
White
Slightly Gray
Slightly Rosy
Creamy
Light Gray
Rosy
Gray
Dark Gray
Note: When a sample has an overall yellowish cast or smut-affected
rough rice has a slight tinge of green, do not show color in the
“RESULTS” section of the work record. Show the following
statement in the “REMARKS” section of the work record and the
certificate: “This rice does not meet the color requirements for U.S.
No. 1 or 2 Rough rice.” The rice cannot be graded higher than U.S.
No. 3.
Note: Black rice typically has a deep purple to “rosy” colored
appearance once the bran has been removed. If the color of the
black rice appears “rosy”, it should receive a grade designation
consistent with that color (i.e., U.S. No. 5). However, should the
rough rice offered for inspection take on a different appearance that
is not addressed in the standards, do not show color in the
“RESULTS” section of the work record. Show the following
statement in the “REMARKS” section of the work record and the
certificate: “This rice does not meet the color requirements for U.S.
No. 1 or 2 Rough rice.” The rice cannot be graded higher than U.S.
No. 3.
For the special grade Parboiled rough rice, color is not a grading factor.
See section 3.33, “Parboiled Rough Rice/Ungelatinized Kernels,” for
special grade determinations based on color level.
d. Record the color on the work record and in the “RESULTS” section of the
certificate except as specified in the Notes above

3.32 SMUTTY ROUGH RICE/SMUTTY KERNELS (VRI R-7.0)
a. Definitions.
(1) Smutty Rough Rice. Smutty rough rice must be rough rice which
contains more than 3.0 percent of smutty kernels.
(2) Smutty Kernels. Whole or broken kernels of rice which are
distinctly infected by smut. Visual Aid: Smut Damage (VRI R-7.0).
b. Basis of Determination. Determine smutty kernels on a representative
portion of no less than 15 grams of rough rice after the removal of
dockage and after shelling, but before milling.
Note: Hand shell any paddy kernels remaining after shelling.
c. Record the percentage of smutty kernels on the work record and in the
“RESULTS” section of the certificate to the nearest tenth percent. If the
rice contains more than 3.0 percent smutty kernels, consider the rice to be
“smutty” and show the special grade “Smutty” on the grade line of the
certificate.
Note: Except as specified, all grades and grade requirements in the
United States Standards for Rough Rice apply to “Smutty Rough
Rice.”

d. False Smut in Rice. False smut (also known as Green smut) is a common
disease found in all rice growing regions. This smut is caused by a
fungus, Ustilaginoidea Virens, which attacks the rice kernels. Eventually,
the kernels are replaced by globose, velvety smut balls that can reach up
to one centimeter in diameter.
(1) Determine False Smut kernels on a representative portion of no
less than a 1,000-grams of rough rice. (Smut balls are typically
removed over the top or middle sieve of the dockage machine.
Smut balls are NOT returned to the dockage free portion.)
(2) The results of this determination will be based on kernel count.
(3) Record the kernel count in the “REMARKS” section of the
certificate as follows:
"(Number) kernels of false smut in 1000 grams."
Note: This factor is not provided for under the United States
Standards for Rough Rice but may be determined upon
request.

3.33 PARBOILED ROUGH RICE/UNGELATINIZED KERNELS
a. Definitions.
(1) Parboiled Rough Rice. Parboiled rough rice must be rough rice in
which the starch has been gelatinized by soaking, steaming, and
drying.
(2) Ungelatinized Kernels. Whole or large broken kernels of parboiled
rice with distinct white or chalky areas due to incomplete
gelatinization of the starch.
Note: Parboiled rough rice must be rough rice in which at
least 90 percent of the kernels are colored by the parboiling
process.
b. Grades.
(1) Grades U.S. No. 1 to U.S. No. 6 inclusive must contain no more
than 10.0 percent of ungelatinized kernels.
(2) Grades U.S. No. 1 and U.S. No. 2 must contain no more than 0.1
percent of nonparboiled rice.
(3) Grades U.S. No. 3 and U.S. No. 4 must contain no more than 0.2
percent of nonparboiled rice.
(4) Grades U.S. No. 5 and U.S. No. 6 must contain no more than 0.5
percent of nonparboiled rice.
c. Degree of Parboiling. If the rice is:
(1) Not distinctly colored by the parboiling process, it must be
considered “Parboiled Light.”
(2) Distinctly but not materially colored by the parboiling process, it
must be considered “Parboiled.”
(3) Materially colored by the parboiling process, it must be considered
“Parboiled Dark.”
Note: The maximum limits for “Chalky kernels,” “Heat-
damaged kernels,” “Kernels damaged by heat,” and the “Color
requirements,” shown in Section 868.210, are not applicable to
the special grade “Parboiled Rough Rice.”
Rice Inspection Handbook
Chapter 3: Rough Rice
August 2020
3-51
d. Basis of Determination. Parboiled rough rice is usually determined by a
cursory examination of whole and large broken kernels of well-milled
rough rice. When a detailed examination is necessary to determine color,
make this determination on a representative portion of approximately 250
grams of whole and large broken kernels of well-milled rough rice.
Describe the rice as either:
(1) “Parboiled light” if it is not distinctly colored by the parboiling
process;
(2) “Parboiled” if it is distinctly, but not materially colored, by the
parboiling process; or
(3) “Parboiled dark” if it is materially colored by the parboiling process.
When a detailed examination is necessary to determine nonparboiled or
ungelatinized kernels, make this determination on a representative portion
of no less than 25 grams of whole and large broken kernels of well-milled
rough rice.
e. Record the percentage of ungelatinized kernels on the work record and in
the “RESULTS” section of the certificate to the nearest tenth percent. If
the rice contains at least 90.0 percent parboiled kernels, consider the rice
to be “parboiled” and show the special grade “Parboiled Light,” “Parboiled,
“or “Parboiled Dark,” as applicable, on the grade line of the work record
and the certificate.
Note: Except as specified, all grades and grade requirements in the
United States Standards for Rough Rice apply to “Parboiled Rough
Rice.”

nonchalky kernels; and
(6) Grade U.S. No. 6 must contain no more than 15.0 percent of
nonchalky kernels.
Note: The maximum limits for “Chalky kernels” in Section
868.210 of the regulations under the AMA are not applicable to
the special grade “Glutinous rough rice.”
b. Basis of Determination. Determine nonchalky kernels on a representative
portion of no less than 25 grams of whole and large broken kernels of
well-milled glutinous rough rice.
c. Record the percentage of nonchalky kernels on the work record and in the
“RESULTS” section of the certificate to the nearest tenth percent. If the
rice is a glutinous variety and contains less than 50.0 percent nonchalky
kernels, consider the rice to be “glutinous” and show the special grade
“Glutinous,” on the grade line of the work record and the certificate.
Note: Except as specified, all grades and grade requirements in the
U.S. Standards for Rough Rice apply to “Glutinous Rough Rice.”

3.35 AROMATIC ROUGH RICE
Definition. Aromatic rough rice must be special varieties of rice (Oryza sativa L.
scented) that have a distinctive and characteristic aroma (e.g., basmati and
jasmine rice).
a. Determine aromatic on the basis of the odor of the lot as a whole, the
representative sample as a whole, or a representative portion of well-
milled rough rice.
b. If the rice is an aromatic variety and has an odor common to such rice,
consider the rice to be “aromatic” and show the special grade “Aromatic”
on the grade line of the work record and the certificate.
Note: Aromatic rice must be declared at the time of inspection
requestor will be considered as having a commercially objectionable
foreign odor and graded U.S. Sample Grade.
3.36 VISUAL REFERENCE IMAGES (VRI)
The visual grading aids system consists of a series of commodity specific VRI’s

4.7 FILE SAMPLE
a. A representative portion of rice (approximate size - 1,250 grams) that may
be used in conjunction with the work sample, when needed, to determine
the complete grade. File samples may also be used for monitoring, retest,
and appeal inspection purposes.
b. Retain file samples in appropriate containers for the required retention
period. After maintaining for the required period, dispose of the file
samples in accordance with established procedures. See FGIS Directive
9170.13, “Uniform File Sample Retention System,” for additional
information.
4.8 PERCENTAGES AND COUNTS
a. Basis of Determination. Percentages are determined upon the basis of
weight and are rounded as follows:
(1) When the figure to be rounded is followed by a figure greater than
or equal to 5, round to the next higher figure (e.g., report 6.36 as
6.4, 0.35 as 0.4, and 2.45 as 2.5).
(2) When the figure to be rounded is followed by a figure less than 5,
retain the figure (e.g., report 8.34 as 8.3, and 1.22 as 1.2).
b. Record percentages as follows:
(1) For milling yield, in tenths of a percent (unrounded) in “RESULTS”
section of the work record and to the nearest whole percent
(rounded from the nearest tenth) on the grade line of the certificate.
(e.g., 66.56 is reported as 66.5 in the results section on the work
record and in the results section and reported as 67 on the grade
line of the certificate.)
(2) For all other factors, to the nearest tenth percent.
c. Record counts, for all factors determined on the basis of count, to the
nearest whole number.

4.10 PRELIMINARY EXAMINATION
a. The sampler must: (1) observe the uniformity of the rice as to type/class,
quality, and condition; (2) make the determination for “Heating;” (3) draw
the representative sample; and (4) report relevant information to the
inspector.
b. The inspector must review the sampler’s remarks/information. If the
inspector has questions or doubts the representativeness of the sample,
he or she must contact the sampler and obtain the needed information or
make arrangements to obtain another sample.
Rice Inspection Handbook
Chapter 4: Brown Rice for
Processing
August 2020
4-10
4.11 BASIS OF DETERMINATION
Certain Quality Determinations. The determination of kernels damaged by heat,
heat-damaged kernels, parboiled kernels in nonparboiled rice, and the special
grade Parboiled brown rice for processing must be on the basis of the brown rice
for processing after it has been milled to a well- milled degree.
Broken Kernels. Broken kernels must be determined by the use of equipment
and procedures prescribed in FGIS instructions or by any method which gives
equivalent results.
All Other Determinations. All other determinations must be on the basis of the
original sample. Mechanical sizing of kernels must be adjusted by handpicking
as prescribed in FGIS instructions, or by any method that is approved by the
Service as giving equivalent results.
Note: When rice that is offered for inspection as one lot is found to contain
more than 10,000 containers (packaged/bags/balers) or 6,000,000 pounds
(bulk) of rice, the lot must be sampled on the basis of two or more
(approximately) equal-sized sublots of 10,000 containers
(packaged/bags/balers) or 6,000,000 pounds or less. Inspect each sublot
separately. (For additional information, see Chapter 7, Roundlot Inspection
Plan, and Chapter 9, Warehouse-Lot Inspection Plan.)
Note: When rice that is offered for inspection as one lot is subsequently
found to contain portions that are distinctly different in class/type, quality,
or condition, the rice in each portion must be inspected separately.
a. Follow a systematic grading procedure. The order of procedure may vary
the class and quality of the rice and the tests that are required to
determine the grade. A general order of procedure is as follows:
(1) Review the information on the work record.
(2) Examine the representative sample for odor and distinctly low
quality.
(3) Use an FGIS-approved divider to process the representative
sample into three representative portions: (1) a work sample, (2) a
file sample, and (3) moisture portion.
Note: For specific information on the operation and
maintenance of dividers, see the FGIS Equipment Handbook,
Chapter 7, Manual Sampling Devices.
Rice Inspection Handbook
Chapter 4: Brown Rice for
Processing
August 2020
4-11
(4) Examine the work sample for:
(a) Class;
(b) Test weight (if requested); and
(c) Type.
(5) Divide the work sample into two representative portions: 750 grams
and 500 grams.
(6) Examine the 500-gram portion for infestation, paddy kernels, and
seeds.
(7) Divide the 500-gram portion to 100 grams and examine the portion
for related and unrelated material.
(8) Divide the 100-gram portion to 50 grams and examine the portion
for paddy kernels and broken kernels removed by a 6 plate or 6 ½
sieve.
(9) Divide out from the 50-gram portion, a 25-gram portion and a 15-
gram portion.
(10) Examine the 25-gram portion for the following:
(a) Chalky kernels;
(b) Well milled kernels;
(c) Red rice and damaged kernels; and
(d) Other types.
(11) Examine the 15-gram portion for smutty kernels.
(12) Mill the 750-gram portion and allow to cool to room temperature.
(a) Examine the milled rice for odor.
(b) Upon request, determine the milling yield (whole kernels and
total milled rice).
(c) Divide the milled rice portion to 500 grams and examine the
portion for heat-damaged kernels and ungelatinized kernels.
Rice Inspection Handbook
Chapter 4: Brown Rice for
Processing
August 2020
4-12
(d) Divide the 500-gram portion of milled rice to 25 grams and
examine the portion for parboiled kernels in nonparboiled
rice and kernels damaged by heat.
b. When the grade (or contract requirements ) of a lot or sample is
determined by a narrow margin (+/-0.1 percent or 1 count) on a single
factor, except for the factors heat-damaged kernels and ungelatinized
kernels on non-cargo lots, another determination must be made on
another representative portion of equivalent size divided out from the work
sample or file sample. The factor result must be based on the average of
the two determinations.
Note: Narrow margin determinations do not apply to multiple lots
where tolerance is applied.
4.12 MOISTURE
Water content in brown rice as determined by an approved device in accordance
with procedures prescribed in FGIS instructions.
Note: Brown rice for processing will not be milled Milling yield will not be
determined when the moisture content exceeds 18.0 percent.
a. Basis of Determination. Determine moisture on a representative portion of
sufficient size of unmilled brown rice for processing as described in the
Moisture Handbook.
b. Procedures. The procedures for performing a moisture determination
using the FGIS-approved moisture meters are described in the Moisture
Handbook.
c. Record the percentage of moisture on the work record and in the
“RESULTS” section of the certificate to the nearest tenth percent. If the
moisture content exceeds 14.5 percent, grade the rice U.S. Sample
Grade.

4.13 TYPE
There are three types of brown rice for processing: (1) Long grain, (2) Medium
grain, and (3) Short grain.
Types must be based on the length/width ratio of kernels of rice that are
unbroken and the width, thickness, and shape of kernels of rice that are broken,

4.14 CLASS
a. There are four classes of brown rice for processing: (1) Long Grain Brown
Rice for Processing, (2) Medium Grain Brown Rice for Processing, (3)
Short Grain Brown Rice for Processing, and (4) Mixed Brown Rice for
Processing.
Classes must be based on the percentage of whole kernels, broken
kernels, and types of rice.
(1) Long Grain Brown Rice for Processing. Long grain brown rice for
processing must consist of brown rice for processing which
contains more than 25.0 percent of whole kernels of brown rice and
no more than 10.0 percent of whole or broken kernels of medium or
short grain rice.
(2) Medium Grain Brown Rice for Processing. Medium grain brown
rice for processing must consist of brown rice for processing which
contains more than 25.0 percent of whole kernels of brown rice and
no more than 10.0 percent of whole or broken kernels of long grain
rice or whole kernels of short grain rice.
(3) Short Grain Brown Rice for Processing. Short grain brown rice for
processing must consist of brown rice for processing which
contains more than 25.0 percent of whole kernels of brown rice and
no more than 10.0 percent of whole or broken kernels of long grain
rice or whole kernels of medium grain rice.
(4) Mixed Brown Rice for Processing. Mixed brown rice for processing
must be brown rice for processing which contains more than 25.0
percent of whole kernels of brown rice and more than 10.0 percent
of “other types’’ as defined in section 4.29, “Other Types,” of this
chapter.
b. Class is usually determined by a cursory examination of the work sample
as a whole.
c. When a detailed examination is necessary to determine whole kernels for
class, make this determination on a representative portion of no less than
25 grams of unmilled brown rice for processing.
(1) Record the percentage of whole kernels on the work record to the
nearest tenth percent.
Rice Inspection Handbook
Chapter 4: Brown Rice for
Processing
August 2020
4-16
(2) If the rice contains 25 percent or less of whole kernels, show the
designation “Brown Rice for Processing” on the grade line of the
certificate. Do not show either a class or grade designation on the
certificate.
d. When a detailed examination is necessary to determine other types for
class, make this determination on a representative portion of no less than
25 grams of unmilled brown rice for processing.
Record the percentage of each type on the work record to the nearest
tenth percent.
e. Grade the rice “Mixed Brown Rice for Processing,” if the rice contains
more than 10 percent of:
(1) Whole or broken kernels of medium or short grain rice in long grain
rice;
(2) Whole and broken kernels of long grain rice or whole kernels of
short grain rice in medium grain rice; or
(3) Whole or broken kernels of long grain rice or whole kernels of
medium grain rice in short grain rice.
f. Determine the percentage of seeds, related material, and unrelated
material, when applicable.
Record the percentage of whole kernels of each type present in the order
of predominance; the percentage of broken kernels of each type present
in order of predominance; and when applicable, the percentage of seeds,
related material, and unrelated material to the nearest tenth percent on the
work record and in the “RESULTS” section of the certificate . (These
percentages must total 100%)
Note: Broken kernels other than long grain in Mixed brown rice for
processing must be certified as “medium or short grain.”

4.15 ODOR
a. Determine odor on the basis of a representative portion of well-milled
brown rice for processing. Upon request, a non-grade odor determination
may be made on the basis of the brown rice, as is.
Off-odors (i.e., musty, sour, and commercially objectionable foreign odor)
can sometimes be detected when smelling the brown rice at the time of
sampling.
Note: If there is any question as to the odor when the sample is
being taken, note on the work record and put that portion of the
sample into an airtight container to preserve its condition for further
examination. The final odor determination is made in the laboratory.
b. The final odor determination must be made on the sample after milling to a
well-milled degree.
(1) A musty odor is any odor that is earthy, moldy, or ground-like. Do
not confuse a burlap bag odor with a musty odor.
(2) A sour odor is any odor that is rancid, sharp, or acrid.
(3) A commercially objectionable foreign odor is any odor that is not
normal to rice and that, because of its presence, renders the rice
unfit for normal commercial usage (e.g., fertilizer, hides, oil
products, skunk, smoke, fire-burnt, and decaying animal and
vegetable matter odors).
(4) Fumigant or insecticide odors are not considered as commercially
objectionable foreign odors unless they are caused by a fumigant
or insecticide that does not dissipate quickly. When the sample of
rice contains a fumigant or insecticide odor that prohibits a true
odor determination, the following guidelines apply:
(a) The representative sample of rice must be allowed to air out
in an open metal container (e.g., a pan) for up to 4 hours, a
fume hood may be used if available; and
(b) If the fumigant or insecticide odor still prohibits the
determination of the rice’s true odor after 4 hours, the rice
must be considered as having a commercially-objectionable
foreign odor.
Rice Inspection Handbook
Chapter 4: Brown Rice for
Processing
August 2020
4-18
Caution: When sampling rice, check for placarded
railcars. If a car is placarded (or if a car is not placarded
but a fumigant odor is detected), do not enter the car or
sample the rice, and notify your supervisor immediately.
Note: Aromatic (scented) rice that has an odor known to
be common to such rice must be declared at the time of
the inspection request or will be considered as having a
commercially objectionable foreign odor.
c. When rice is determined to be musty, sour, or have a commercially-
objectionable foreign odor, record the type of odor on the work record and
in the “RESULTS” section of the certificate, and grade the rice U.S.
Sample Grade.
Note: Brown rice for processing found to have a commercially
objectionable foreign odor is considered actionable according to
FGIS Directive 9060.2, “Implementation of the FGIS-FDA
Memorandum of Understanding.”
4.16 HEATING
a. Determine heating on the basis of the lot as a whole.
(1) When high temperature develops in rice as the result of excessive
respiration, such rice is heating.
(2) Heating rice usually gives off a sour or musty odor.
(3) Care should be taken never to confuse rice that is warm due to
storage in bins, carriers, or other containers during hot weather with
rice that is heating from excessive respiration.
b. When applicable, show the term “Heating” on the work record and in the
“RESULTS” section of the certificate, and grade the rice U.S. Sample
Grade.

4.17 DISTINCTLY LOW QUALITY
a. Determine Distinctly Low Quality on the basis of the lot as a whole or the
representative sample as a whole or an auxiliary sample.
b. Brown rice for processing that is obviously affected by unusual conditions
which adversely affect the quality of the rice and which cannot be graded
properly by use of the grading factors specified or defined in the
standards, must be considered as being of distinctly low quality. Brown
rice for processing that contains any material too large to enter a probe,
Ellis cup, pelican, DT sampler or any official sampling device such as
pieces of wreckage and debris including lumps of rice, grain, dirt and/or
other commodities, unknown foreign substance or toxic material which are
visible to the sampler is considered DLQ.

4.18 INSECT INFESTATION
a. Infested Brown Rice for Processing. Tolerances for live insects for
infested brown rice are defined according to sampling designation as
follows:
(1) Representative Sample. The representative sample consists of the
work portion, and the file sample if needed and when available.
The brown rice (except when examined according to paragraph
(a)(3) of this section) will be considered infested if the
representative sample contains two or more live weevils, or one live
weevil and one or more other live insects injurious to stored rice, or
five or more other live insects injurious to stored rice.
(2) Lot as a Whole (Stationary). The lot as a whole is considered
infested when two or more live weevils, or one live weevil and one
or more other live insects injurious to stored rice, or five or more
other live insects injurious to stored rice, or fifteen or more live
Angoumois moths or other live moths injurious to stored rice are
found in, on, or about the lot.
(3) Sample as a Whole During Continuous Loading/Unloading. The
minimum sample size for rice being sampled during continuous
loading/unloading is 500 grams per each 100,000 pounds of rice.
The sample as a whole is considered infested when a component
(as defined in FGIS instructions) contains two or more live weevils,
or one live weevil and one or more other live insects injurious to
stored rice, or five or more other live insects injurious to stored rice.
Note: “Weevils” must include coffee bean weevils, broad-
nosed grain weevils, rice weevils, granary weevils, maize
weevils, and lesser grain borers. “Other live insects injurious
to stored rice” must include beetles, moths, meal worms, and
other insects injurious to stored rice.
Note: To aid in insect identification, refer to FGIS Visual
Reference Images (VRI) and/or the FGIS Stored-Grain Insect
Reference.
b. Determine infestation on the basis of a representative portion of
approximately 500 grams of unmilled brown rice for processing, the lot as
a whole, and/or a component sample taken during continuous
loading/unloading.
(1) Examine a representative portion.
Rice Inspection Handbook
Chapter 4: Brown Rice for
Processing
August 2020

(a) If no live insects are found in the portion, make no further
check of the sample for insects.
(b) If two or more live insects are found, consider the rice to be
“U.S. Sample Grade.”
(c) If one live insect is found, cut another representative portion
of approximately 500 grams from the file sample. (Use the
rest of the representative sample if the file sample is less
than 500 grams.)
1 If one or more live insects are found in the second
portion, consider the rice to be “U.S. Sample Grade.”
2 If no live insects are found in the second portion, do
not consider the rice to be “U.S. Sample Grade.”
(2) Examine the rice in the lot (i.e., the surface area of the lot and the
area around the lot).
(a) If no live insects are found in, on, or around the lot, make no
further check of the lot for insects.
(b) If two or more live insects are found, consider the rice to be
“U.S. Sample Grade.”
(3) Examine the component samples
5
taken during continuous
loading/unloading.
(a) Divide out from each component sample a representative
portion of approximately 500 grams.
(b) Examine the representative portion for live insects.
1 If no live insects are found in the representative
portion, make no further check of the component for
insects.
2 If two or more live insects are found, consider the rice
to be “U.S. Sample Grade.”

Processing
August 2020
4-22
3 If one live insect is found, cut another representative
portion of approximately 500 grams from the
component sample.
a If one or more live insects are found in the
second portion, consider the rice to be “U.S.
Sample Grade.”
b If no live insects are found in the second
portion, do not consider the rice to be “U.S.
Sample Grade.”
c. When applicable, show count on the work record and in the “RESULTS”
section of the certificate, and grade the rice “U.S. Sample Grade.”
Note: Brown rice for processing found to contain live insects and
graded U.S. Sample Grade is considered actionable according to
FGIS Directive 9060.2, “Implementation of the FGIS-FDA
Memorandum of Understanding.”
Note: If a lot of Brown rice for processing was determined to be
infested and downgraded to U.S. Sample Grade, the lot may be
fumigated to remove the “U.S. Sample Grade” designation pending
specific fumigation criteria is met. Refer to the Fumigation
Handbook for specific criteria and certification procedures.

4.19 TEST WEIGHT PER BUSHEL
Note: This factor is not provided for under the “U.S. Standards for Brown
Rice for Processing,” but may be determined upon request.
a. Determine test weight per bushel on a representative portion of
approximately 1,000 grams of unmilled brown rice for processing.
b. General Operating Procedures.
(1) Level and balance the test weight per bushel apparatus.
(2) Close the hopper valve.
(3) Pour the work sample into the hopper.
(4) Center the hopper over the kettle.
(5) Fill the kettle by opening the hopper valve quickly.
(6) Move the hopper all the way to the left before proceeding. Do not
jar the apparatus. Jarring could cause inaccurate results.
(7) Using a standard stroker, stroke the kettle by holding the stroker in
both hands with the flat sides in a vertical position. Level the rice in
the kettle by making three full-length, zigzag motions with the
stroker.
(8) Convert the weight of the sample by either the “standard” method
or one of the “alternate” methods.
(a) Standard Method. Carefully hang the kettle on the beam
and move the weights until the beam is balanced. Read the
test weight per bushel scale.
(b) Alternate Method – Manual Conversion. Pour the sample
from the kettle onto a general class scale, note the weight of
the sample, find the gram weight on the test weight
conversion chart (see Appendix 3, “Uniformity Tolerance
Tables”), and read the corresponding test weight per bushel
shown to the right of the gram weight.
Rice Inspection Handbook
Chapter 4: Brown Rice for
Processing
August 2020
4-24
(c) Alternate Method – Automatic Conversion. When using an
electronic scale programmed to convert gram weight to
pounds per bushel select the appropriate test weight mode.
Place an empty sample pan or the test weight kettle on the
scale and zero the scale. Pour the sample from the kettle
into the sample pan or place the filled kettle onto the scale
as appropriate. Read the result from the test weight mode
selected.
c. Record the test weight per bushel on the work record to the nearest tenth
of a pound and record in the “RESULTS” section of the certificate.
d. Upon request by the applicant the following statement may be recorded in
the “REMARKS” section of the certificate:
“Test weight per bushel of (amount) pounds is approximately
equivalent to (amount) kilograms per hectoliter.”
Kilograms per hectoliter are determined by multiplying the test weight per
bushel by 1.287.
Note: Bulk density may be determined by dividing the test weight
per bushel by 1.2445. Bulk density is the number of pounds in one
cubic foot.

4.20 MILLING YIELD
Definition. An estimate of the quantity of whole kernels and total milled rice
(whole and broken kernels combined) that is produced in the milling of brown rice
for processing to a well-milled degree.
Note: Brown rice for processing will not be milled when the moisture
content exceeds 18.0 percent.
a. Determine milling yield on a representative portion of 750 grams of
unmilled brown rice for processing using an FGIS-approved miller.
(1) Divide out a representative portion of between 725 and 775 grams.
(2) Add or remove kernels (by finger pinching, not pouring) until exactly
750 grams is obtained.
b. Milling yield is determined by converting the brown rice for processing to
milled rice and then separating the whole kernels from the total milled rice
portion.
c. Mill the brown rice for processing.
(1) If the miller has not been used recently, warm up the miller, as
follows:
(a) Place approximately 750 grams of milled rice or brown rice
in the milling chamber with a 2-pound weight on the weight
holder.
(b) Make at least three consecutive 30-second runs.
(c) Thoroughly clean the miller.
(2) Proceed with the milling of the 750-gram portion.
(a) Set the miller’s timer switch at exactly 30 seconds.
(b) Tilt the chamber so that the rice will flow uniformly beneath
the milling cylinder and pour the entire portion of brown rice
into milling chamber.
(c) Close the milling chamber and return it to the milling
position.
(d) Position the saddle and weight arm on the milling chamber.

Note: For Mixed brown rice for processing, use the weight prescribed for the
type of rice that predominates in the mixture.
(g) Start the miller for the 30-second milling cycle.
(h) After milling, reduce the weight to the brushing cycle
requirements.
(i) Start the miller for the 30-second brushing cycle.
(j) After brushing, remove the weights, weight holder, weight
arm, and saddle.
(k) Clean the miller and the hopper.
(l) Place a container under the hopper opening and transfer the
rice from the milling chamber into the container. Do not
close or seal the container.
(m) Allow the sample to cool to room temperature before
removing it from the container.
(3) Examine the rice for milling degree.
In determining milling yield in brown rice, the degree of milling must
be equal to, or better than, that of the Visual Aid: Well-Milled.
Rice Inspection Handbook
Chapter 4: Brown Rice for
Processing
August 2020
4-27
If it is determined that the rice is not equal to or better than the
Visual Aid: Well-Milled, pour the rice back into the miller and repeat
the brushing cycle.
d. Determine the percentage of total milled rice. Total milled rice is the
whole and broken kernels that are produced in the milling of brown rice to
a well-milled degree.
(1) Weigh the rice after milling and divide this weight by the weight of
the rice before milling.
For Example: The sample of brown rice for processing
weighs 750 grams before milling. After milling,
the sample weighs 650 grams.
650 grams ÷ 750 grams = 86.6% = 87% total milled rice
Record the percentage of total milled rice in tenths of a percent
(unrounded) in “RESULTS” section of the work record and to the
nearest whole percent (rounded from the nearest tenth) on the
grade line of the certificate.
e. Determine the percentage of whole kernels.
Whole Kernels. Unbroken kernels of rice and broken kernels of rice which
are at least three- fourths of an unbroken kernel. Seeds or other material
other than rice are considered a broken kernel.
(1) Divide out a representative portion of no less than 40 grams of well-
milled brown rice for processing.
(2) Remove the whole kernels from the well-milled brown rice portion
using any device or method that will facilitate the separation of the
whole kernels from the broken kernels.
(3) Determine the percentage of whole kernels in the 40-gram portion
and then multiply this percentage by the percentage (unrounded) of
total milled rice.
Rice Inspection Handbook
Chapter 4: Brown Rice for
Processing
August 2020
4-28
For Example: The 40-gram portion weighed 40.61 grams of
well-milled brown rice and contains 34.51
grams of whole kernels (84.9 percent of whole
kernels). The percentage of total milled rice is
86.6 percent before rounding.
34.51g ÷ 40.61g = 84.9%
84.9% x 86.6% = 73.5% = 74% whole kernels
Note: Carry out all figures used in the calculations to tenths of
a percent. Do not carry out to hundredths.
(4) Record the percentage of whole kernels in tenths of a percent
(unrounded) in “RESULTS” section of the work record and to the
nearest whole percent (rounded from the nearest tenth) on the
grade line of the certificate.
For Example: U.S. No. 2 Long Grain Brown Rice for
Processing Milling Yield 74-87
Results: Whole Kernels 73.5%
Total Rice 86.6%

4.21 MILLING ANALYSIS
a. Milling analysis provides an estimate of the quantity (percentage) of whole
kernels, second head-sized kernels, screenings-sized kernels, and
brewers-sized kernels that are produced in the milling of a lot of brown rice
for processing.
Note: This factor is not provided for under the U.S. Standards for
Brown Rice for Processing, but may be determined upon request.
b. The following definitions are applicable only to this determination:
(1) Whole Kernels. Unbroken kernels of rice and broken kernels of rice
that are at least three-fourths of an unbroken kernel.
(2) Second Head Kernels. Broken kernels of rice and other material
that remain on top of a 6 sieve.
(3) Screenings Kernels. Broken kernels of rice and other material that
pass through a 6 sieve but remain on top of a 5 1/2 sieve.
(4) Brewers Kernels. Broken kernels of rice and other material that
pass through a 5 1/2 sieve.
c. Determine the percentage of whole kernels on a representative portion of
no less than 25 grams of well-milled brown rice for processing.
(1) Remove the broken kernels from the 25-gram portion using any
device or method that will facilitate the separation of the broken
kernels from the whole kernels.
(2) Determine the percentage of whole kernels by subtracting the
percentage of broken kernels from 100.0 percent.
Example: 100.0% - 19.6% TBK = 80.4%WK
(3) Calculate the adjusted base by dividing the percentage of whole
kernels by 100.
Example: 80.4% WK ÷ 100 = .80 adjusted base
d. Determine the percentage of screenings kernels and brewers kernels on a
representative portion of no less than 125 grams.
(1) Nest a 6 sieve on top of a 5 1/2 sieve in a bottom pan.
Rice Inspection Handbook
Chapter 4: Brown Rice for
Processing
August 2020
4-30
(2) Place the sieves in a mechanical grain sizer and set the timer to 20.
(3) Put the rice in the center of the top sieve and turn on the sizer.
Note: If a mechanical sizer is unavailable, hold the sieves and
bottom pan level and, using a steady motion, move the sieves
from right to left approximately 10 inches, and return from left
to right to complete one sieving operation. Repeat this
operation 20 times.
(4) Return the material remaining in the perforations of the sieve to the
portion that remains on top of the sieve.
(5) Consider all material that passed through the 6 sieve, but remains
on top of the 5 1/2 sieve, as screenings kernels. Do not hand adjust
the separation.
(6) Consider all material that passes through the 5 1/2 sieve as
brewers kernels. Do not hand adjust the separation.
e. Adjust the percentage of screenings and brewers by multiplying the
“actual” percentage of screenings and brewers by the adjusted base.
Example: 2.1% SMR X .80 = 1.7% SMR
1.3% BMR X .80 = 1.0% BMR
f. Determine the percentage of second head kernels by adding the
percentage of screenings and brewers kernels together and then
subtracting that total from the percentage of broken kernels.
Example: 19.6% TBK - (1.7% SMR + 1.0% BMR)
= 16.9% SHMR
g. Record the percentage of whole kernels, second head kernels, screenings
kernels, and brewers kernels on the work record and in the “RESULTS”
section of the certificate to the nearest whole percent.

Note: Cold mold kernels are kernels of rice that are discolored by a
storage fungi which ranges from a light to dark amber/brown in color and
can be distinguished from other types of damage or heat damage by its
translucent appearance. Cold mold would generally function as damage;
however, if the color intensity meets or exceeds that depicted in Visual Aid:
Heat Damage (VRI R-2.0), it would then function as heat damage.
a. Determine the number of heat-damaged kernels on a representative
portion of 500 grams of well-milled brown rice for processing.
(1) Divide out a representative portion of between 475 and 525 grams.
(2) Add or remove kernels (by finger pinching, not pouring) until exactly
500 grams is obtained.
b. Remove and weigh the heat-damaged kernels. Consider each 0.02
grams of heat- damaged kernels as “one heat-damaged kernel in 500
grams.” Round the results to the lowest number.
For Example: 0.01 grams of HT = 0 HT
0.02 grams of HT = 1 HT kernel
0.03 grams of HT = 1 HT kernel
0.04 grams of HT = 2 HT kernels
c. When it is determined by general observation that the 500-gram portion
contains 75 or more heat-damaged kernels, divide the 500-gram portion
into two portions: a 100-gram portion and a 400-gram portion.
(1) Examine the 100-gram portion for heat-damaged kernels.
(2) If the 100-gram portion contains 25 or more heat-damaged kernels,
multiply the number of kernels found by 5.
(3) If the 100-gram portion contains less than 25 heat-damaged
kernels, examine the 400-gram portion and add the number of
heat-damaged kernels found in both portions together.
d. Record the number of heat-damaged kernels on the work record and in
the “RESULTS” section of the certificate.

4.25 RED RICE AND DAMAGED KERNELS
a. Definitions.
(1) Red Rice. Whole or broken kernels of rice on which the bran is
distinctly red in color.
(2) Damaged Kernels. Whole or broken kernels of rice which are
distinctly discolored or damaged by water, insects, heat, or any
other means (including parboiled kernels in nonparboiled rice and
smutty kernels). “Heat-damaged kernels” must not function as
damaged kernels.
b. Basis of Determination. Determine red rice and damaged kernels (other
than damaged by heat and parboiled kernels in nonparboiled rice) on a
representative portion of no less than 25 grams of unmilled brown rice for
processing.
(1) Determine kernels damaged by heat and parboiled kernels in
nonparboiled rice on a representative portion of no less than 25
grams of well-milled brown rice for processing.
(2) Red rice is rice that has a streak of red bran one-half or more the
length of the kernel, or two or more streaks that total one-half or
more the length of the kernel. A kernel or a piece of kernel of rice
that does not have sufficient red bran to be considered as red rice
must be considered as long grain, medium grain, or short grain rice
as appropriate.
Note: Black rice would function as red rice. Black rice is rice
that has a streak of black bran one-half or more the length of
the kernel, or two or more streaks that total one-half or more
the length of the kernel. A kernel or piece of a kernel that does
not have sufficient black bran to be considered as red rice will
be considered as long grain, medium grain, or short grain as
appropriate and could function as other types.
c. Types. The major types of damaged kernels are as follows:
(1) Insect-Bored Kernels.
Whole or broken kernels of rice that have been bored by insects.
Kernels that are only slightly eaten by insects and are clean in
appearance will be considered as sound kernels.

Processing
August 2020
4-36
(2) Pecky Kernels Damage (VRI R-2.7) and Water, Stain, and Peck
Damaged (Glutinous Rice) (VRI R-2.71).
Whole or broken kernels of rice that have one or more black,
brown, red, or other discolored spots or areas on them caused by
fungus growth or insects. Mold is defined as a fungus growth and
therefore, will be treated as fungus-damaged. Visual Aid: Pecky
Kernels Damage (VRI R-2.7). Visual Aid: Water, Stain, and Peck
Damaged (Glutinous Rice) (VRI R-2.71).
(3) Damaged by Heat (Stain) (VRI R-2.1).
Whole or broken kernels of rice that are distinctly discolored to the
minimum color intensity illustrated. There is no minimum coverage
requirement but are lighter in color than the Visual Reference
Image for heat-damaged kernels. Visual Aid: Damaged by Heat
(Stain) (VRI R-2.1).
Lightly Stained (Not Damage) (VRI R-2.2).
Whole or broken kernels of rice that are not damaged but have a
light discoloration (stain) equal to or greater than color shown on
the VRI. There is no minimum coverage requirement. Visual Aid:
Lightly Stained (Not Damage) (VRI R-2.2).
Note: This factor is not provided for under the United States
Standards for Brown Rice for Processing, but may be
determined upon request.
(4) Parboiled Rice in Nonparboiled Rice.
Whole or broken kernels of parboiled rice in nonparboiled rice that
are lighter in color than the Visual Aid: Heat Damage (VRI R-2.0).
(5) Other Damaged Kernels.
Whole or broken kernels of rice that are distinctly discolored or
damaged from causes other than those listed above will be
considered as damaged kernels. However, those whole and broken
kernels that show sheller marks, but are otherwise not distinctly
discolored or damaged, will not function as damaged kernels.
d. Record the percentage of red rice and damaged kernels on the work
record and in the “RESULTS” section of the certificate to the nearest tenth
percent.
Rice Inspection Handbook
Chapter 4: Brown Rice for
Processing
August 2020

0.051-inch thick, perforated with rows of round holes 0.0938 (6/64)
inch in diameter, 5/32 inch from center to center, with each row
staggered in relation to the adjacent rows, and a bottom lamina
0.091-inch thick, without perforations.
(2) 6 ½ Sieve. A metal sieve 0.032-inch thick, perforated with rows of
round holes 0.1016 (6 ½ /64) inch in diameter, 5/32 inch from
center to center, with each row staggered in relation to the adjacent
rows.
b. Basis of Determination. Determine broken kernels removed by a 6 plate
or a 6 1/2 sieve on a representative portion of no less than 50 grams of
unmilled brown rice for processing.
c. For southern production rice:
(1) Place a 6 plate in the bottom carriage of the rice sizing device.
(2) Pour the 50-gram portion on the plate. After the sample is poured,
place the emptied triangular pan under the hopper to catch the rice
that flows over the plate.
(3) Turn the machine on. Allow the machine to run until the rice stops
flowing over the plate into the triangular pan.
Rice Inspection Handbook
Chapter 4: Brown Rice for
Processing
August 2020
4-39
(4) After the rice stops flowing and the machine is turned off, remove
the plate and empty the contents into the rectangular container.
Lightly tap the bottom of the plate to remove material retained in the
perforations of the plate.
(5) Hand adjust the material that lodges in the 6 plate to remove any
whole kernels, any broken kernels that obviously do not belong with
the 6 plate brokens, any seeds, and any related or unrelated
material.
d. For western production rice:
(1) Mechanical Sieving Method.
(a) Mount a 6 ½ sieve with a bottom pan on a mechanical sieve
shaker.
(b) Make sure the shaker and sieve are level.
(c) Set the stroke counter for 20 strokes
(d) Gently pour the representative portion of grain rice in the
center of the sieve.
(e) Turn the machine on.
(f) After the required number of strokes has been completed,
the machine will automatically stop.
(g) Carefully remove the sieve and bottom pan. Jarring the
sieve will cause the material remaining on top to pass
through the perforations, leading to inaccurate results.
(h) Combine the material lodged in the perforations with the
material that remained on top of the sieve. To remove the
lodged material from the perforations, rub the sieve bottom
gently. Tapping will warp the sieve and lead to inaccurate
results in future determinations.
For more specific information on the operation, maintenance,
and performance sieves and sieve shakers, see the sieves
chapter in the Equipment Handbook.

(i) Hand adjust the material that passes through the 61/2 sieve
to remove any whole kernels, any broken kernels that
obviously do not belong with the 6 sieve brokens, any seeds,
and any related or unrelated material.
(2) Hand Sieving Method.
(a) Mount a 6 1/2 sieve on a bottom pan.
(b) Pour the representative portion in the center of the sieve.
(c) Hold the sieve level in both hands with elbows close to the
body. In a steady motion, move the sieve from left to right
approximately 10 inches, and return from right to left.
(d) Repeat the sieving operation 20 times.
(e) Combine the material lodged in the perforations with the
material that remained on top of the sieve. To remove the
lodged material from the perforations, rub the sieve bottom
gently. Tapping will warp the sieve and lead to inaccurate
results in future determinations.
(f) Hand adjust the material that passes through the 6 1/2 sieve
to remove any whole kernels, any broken kernels that
obviously do not belong with the 6 1/2 sieve brokens, any
seeds, and any related or unrelated material.
e. Record the percentage of broken kernels removed by a 6 plate or 6 1/2
sieve on the work record and in the “RESULTS” section of the certificate
to the nearest tenth percent.

5.3 SPECIAL GRADES AND SPECIAL GRADE REQUIREMENTS
a. The special grades and special grade requirements for all classes of
milled rice are shown in the United States Standards for Rice (Section
868.315 of regulations under the AMA).
b. A special grade, when applicable, is supplemental to the grade assigned.
Such special grades for milled rice are defined as follows:
(1) Coated Milled Rice. Coated milled rice must be rice which is
coated, in whole or in part, with substances that are safe and
suitable as defined in the regulations issued pursuant to the
Federal Food, Drug, and Cosmetic Act (FDA) as 21 CFR 130.3(d).
(2) Granulated Brewers Milled Rice. Granulated brewers milled rice
must be milled rice which has been crushed or granulated so that
95.0 percent or more will pass through a 5 sieve, 70.0 percent or
more will pass through a 4 sieve, and no more than 15.0 percent
will pass through a 2½ sieve.
(3) Parboiled Milled Rice. Parboiled milled rice must be milled rice in
which the starch has been gelatinized by soaking, steaming, and
drying.
If the rice is:
(a) Not distinctly colored by the parboiling process, the rice must
be considered “Parboiled Light.”
(b) Distinctly but not materially colored by the parboiling
process, the rice must be considered “Parboiled.”
(c) Materially colored by the parboiling process, the rice must be
considered “Parboiled Dark.”
(4) Undermilled Milled Rice. Undermilled milled rice must be milled
rice which is not equal to the milling requirements for “hard milled,”
“well-milled,” and “reasonably well-milled” rice.
(5) Glutinous Milled Rice. Special varieties of rice (Oryza sativa L.
glutinosa) which contain more than 50 percent of chalky kernels.
(6) Aromatic Milled Rice. Special varieties of rice (Oryza sativa L.
scented) that have a distinctive and characteristic aroma (e.g.,
basmati and jasmine rice).

5.4 WORK RECORD
Record the results of all tests and findings clearly and accurately on a sample
ticket or similar form. This will be used as the source of the information reported
on the inspection certificate. FGIS personnel must use FGIS-911, “Rice Sample
Ticket,” to record inspection results. Cooperators must use a similar form.
5.5 REPRESENTATIVE PORTION
A specified quantity of rice divided out from the representative sample by means
of an FGIS-approved divider.
5.6 WORK SAMPLE
A representative portion of rice (approximate size - 1,000 grams) that is used to
make all such determinations required for a particular class of rice.
Note: A Submitted Sample of milled rice with a request for grade that does
not contain 500 grams or more will be dismissed; or a factor only
inspection may be performed upon request.
5.7 FILE SAMPLE
a. A representative portion of rice (approximate size - 1,250 grams) that may
be used in conjunction with the work sample, when needed, to determine
the complete grade. File samples may also be used for monitoring, retest,
and appeal inspection purposes.
b. Retain file samples in appropriate containers for the required retention
period. After maintaining for the required period, dispose of the file
samples in accordance with established procedures. See FGIS Directive
9170.13, “Uniform File Sample Retention System” for additional
information.
Rice Inspection Handbook
Chapter 5: Milled Rice
August 2020
5-11
5.8 PERCENTAGES AND COUNTS
a. Basis of Determination. Percentages are determined upon the basis of
weight and are rounded as follows:
(1) When the figure to be rounded is followed by a figure greater than
or equal to 5, round to the next higher figure (e.g., report 6.36 as
6.4, 0.35 as 0.4, and 2.45 as 2.5).
(2) When the figure to be rounded is followed by a figure less than 5,
retain the figure (e.g., report 8.34 as 8.3, and 1.22 as 1.2).
b. Record percentages as follows:
(1) For broken kernels removed by a 5 plate in U.S. No. 1 and 2 Milled
rice and for objectionable seeds in U.S. No. 1 Brewers milled rice,
to the nearest hundredth percent.
(2) For all other factors, to the nearest tenth of percent.
c. Record counts, for all factors determined on the basis of count, to the
nearest whole number.
5.9 LABORATORY SCALES
Weigh samples and portions of samples using the proper class of FGIS-
approved laboratory scales, and record the results to the correct division size.
Use the table below to determine the scale class and division size required for
weighing particular sized samples.

5.10 PRELIMINARY EXAMINATION
a. The sampler must: (1) observe the uniformity of the rice as to type/class,
quality, and condition; (2) make the determination for “Heating;” (3) draw
the representative sample; and (4) report relevant information to the
inspector.
b. The inspector must review the sampler’s remarks/information. If the
inspector has questions or doubts the representativeness of the sample,
he or she must contact the sampler and obtain the needed information or
make arrangements to obtain another sample.
5.11 BASIS OF DETERMINATION
Certain Quality Determinations. All determinations must be on the basis of the
original sample. Mechanical sizing of kernels must be adjusted by handpicking,
as prescribed in FGIS instructions, or by any method which gives equivalent
results.
Broken Kernels. Broken kernels must be determined by the use of equipment
and procedures prescribed in FGIS instructions or by any method which gives
equivalent results.
Note: When rice that is offered for inspection as one lot is found to contain
more than 10,000 containers (packaged/bags/balers) or 6,000,000 pounds
(bulk) of rice, the lot must be sampled on the basis of two or more
(approximately) equal-sized sublots of 10,000 containers
(packaged/bags/balers) or 6,000,000 pounds or less. Inspect each sublot
separately. (For additional information, see Chapter 7, Roundlot Inspection
Plan, and Chapter 9, Warehouse-Lot Inspection Plan.)
Note: When rice that is offered for inspection as one lot is subsequently
found to contain portions that are distinctly different in class/type, quality,
or condition, the rice in each portion must be inspected separately.
a. Follow a systematic grading procedure. The order of procedure may vary
depending on the class and quality of the rice and the tests that are
required to determine the grade. A general order of procedure is as
follows:
(1) Review information on the work record.
(2) Examine the representative sample for odor and distinctly low
quality.
Rice Inspection Handbook
Chapter 5: Milled Rice
August 2020
5-13
(3) Use an FGIS-approved divider to process the representative
sample into three representative portions: (1) a work sample, (2) a
file sample, and (3) a moisture portion.
Note: For specific information on the operation and
maintenance of dividers, see the FGIS Equipment Handbook,
Chapter 7, Manual Sampling Devices.
(4) Examine the work sample for test weight (if requested) and type.
(5) Divide the 1,000-gram work sample to 500 grams and examine the
portion for:
(a) Infestation;
(b) Paddy kernels (all classes except BMR);
(c) Seeds (all classes except BMR); and
(d) Heat-damaged kernels (all classes except SMR and BMR).
(6) Divide the 500-gram portion to approximately 250 grams and
examine the portion for:
(a) Milling (degree) requirements; and
(b) Color.
(7) Divide out from the 250-gram portion a 100-gram portion and a 50-
gram portion.
(8) Examine the 100-gram portion for foreign material (all classes
except BMR).
(9) Examine the 50-gram portion for:
(a) Broken kernels removed by a 5 plate and a 6 plate, or that
pass through a 6 sieve;
(b) Class (for SHMR, SMR, and BMR); and
(c) 30 sieve material.
Rice Inspection Handbook
Chapter 5: Milled Rice
August 2020
5-14
(10) Divide the 50-gram portion to no less than 25 grams and examine
the portion for:
(a) Broken kernels total;
(b) Chalky kernels;
(c) Class (whole kernels for LGMR, MGMR, and SHGMR);
(d) Foreign material (for BMR);
(e) Heat-damaged kernels, kernels damaged by heat, and/or
parboiled kernels in nonparboiled rice (for SMR and BMR);
(f) Other types (whole kernels, and whole and broken kernels);
(g) Red rice and damaged kernels;
(h) Seeds and paddy kernels (for BMR);
(i) Ungelatinized kernels; and
(j) Well milled kernels.
b. When the grade (or contract requirements) of a lot or sample is
determined by a narrow margin (+/- 0.1 percent or 1 count) on a single
factor, another determination must be made on another representative
portion of equivalent size divided out from the work sample or file sample.
The factor result must be based on the average of the two determinations.
Note: Narrow margin determinations do not apply to multiple lots
where tolerance is applied.

5.12 MOISTURE
Water content in milled rice as determined by an FGIS approved device in
accordance with according to procedures prescribed in FGIS instructions.
a. Bass of Determination. Determine moisture on a representative portion of
sufficient size of milled rice as described in the Moisture Handbook.
b. Procedures. The procedures for performing a moisture determination
using the FGIS-approved moisture meters are described in the Moisture
Handbook.
c. Record the percentage of moisture on the work record and in the
“RESULTS” section of the certificate to the nearest tenth percent. If the
moisture content exceeds 15.0 percent, grade the rice “U.S. Sample
Grade.”
5.13 TYPE
There are three types of milled rice: (1) Long grain, (2) Medium grain, and (3)
Short grain.
Types must be based on the length/width ratio of kernels of rice that are
unbroken and the width, thickness, and shape of kernels that are broken,
prescribed in FGIS instructions.
FIGURE 5.1 – MILLED RICE LENGTH/WIDTH RATIO
a. The length-width ratio limitations for milled rice are:

Short grain
3.0 (or more) to 1
2.0 - 2.9 to 1
1.9 (or less) to 1
b. Type is usually determined by a cursory examination of the work sample
as a whole.
c. When a detailed examination is necessary, measure the length and width
of 15 unbroken kernels of milled rice taken at random from the work
sample and determine their average length-width ratio.
(1) Length is the distance between the most distant tips of the kernel.
(2) Width is the distance across the kernel at the widest point.

determination on a representative portion of no less than 25 grams.
(1) Record the percentage of each type on the work record to the
nearest tenth percent.
(2) If the rice contains more than 10 percent of “other types,” grade the
rice “Mixed Milled Rice.”
Determine the percentage of seeds and foreign material, when applicable.
Record the percentage of whole kernels of each type present in the order
of predominance; the percentage of broken kernels of each type present
in order of predominance; and when applicable, the percentage of seeds
and foreign material to the nearest tenth percent on the work record and in
the “RESULTS” section of the certificate. (These percentages must total
100%).
Note: Broken kernels other than long grain, in Mixed milled rice,
must be certified as “medium or short grain.”

f. When a detailed examination is necessary to determine class of second
head, screening, or brewers milled rice, make this determination on a
representative portion of no less than 50 grams.
(1) Southern Production.
(a) Mount a 4 sieve in a bottom pan.
(b) Place the sieve in a mechanical grain sizer and set the timer
to 20. Put the rice in the center of the top sieve and start the
sizer. (If a mechanical sizer is not available, hold the sieves
and bottom pan level and using a steady motion, move the
sieve from right to left approximately 10 inches, and return
from left to right to complete one sieving operation. Repeat
this operation 20 times.)
(c) Return the broken kernels that lodged in the perforations of
the sieve to the portion that remains on the top of the sieve.
(d) Place a 5 plate in the top carriage and a 6 plate in the
bottom carriage of the sizing device.

over the plates.
(f) Hand adjust the broken kernels that passed through the 4
sieve, and the broken kernels that are removed by the 5
plate and 6 plate by removing any whole kernels, broken
kernels that obviously do not belong in a particular
separation*, seeds, and foreign material.
*Material passing through a 4 sieve and lodged in the 5 and
6 plate perforations must pass through and/or lodge without
touching the side of the opening when turned to the widest
girth.
Note: It is permissible to use a No. 20 wire mesh sieve
as an aid in hand-adjusting 4 sieve material.
(g) Determine the percentage of broken kernels that passed
through the 4 sieve and the percent removed by the 5 plate
and by the 6 plate.
(2) Western Production.

sieve, 6 sieve, and a 5½ sieve in a bottom pan, as deemed
necessary.
(b) Place the sieves in a mechanical grain sizer and set the
timer to 20. Put the rice in the center of the top sieve and
start the sizer. (If a mechanical sizer is not available, hold
the sieves and bottom pan level and using a steady motion,
move the sieve from right to left approximately 10 inches,
and return from left to right to complete one sieving
operation. Repeat this operation 20 times.)
(c) Return the broken kernels that lodged in the perforations of
each sieve to the portion that remains on the top of each
sieve.
(d) Hand adjust the broken kernels that passed through the
sieves by removing any whole kernels, broken kernels that
obviously do not belong in a particular separation, seeds,
and foreign material.
Note: It is permissible to use a No. 12 or 14 wire mesh
sieve as an aid in hand-adjusting 6 sieve material.
(e) Determine the percentage of broken kernels that passed
through the 5½, 6, and 6½ sieves.
g. Record the percent of each plate or sieve separation on the work record
and on the certificate to the nearest tenth percent.
h. If the rice contains more than 25 percent of whole kernels, consider the
rice to be long grain, medium grain, short grain or mixed milled rice.

5.15 ODOR
a. Determine odor on the basis of the lot as a whole or the representative
sample as a whole.
Off-odors (i.e., musty, sour, and commercially objectionable foreign odor)
are can sometimes be detected when smelling the milled rice at the time
of sampling.
Note: If there is any question as to the odor when the sample is
being taken, a part of the sample must be put into an airtight
container to preserve its condition for further examination.
b. The final odor determination is made in the laboratory. All portions must
be returned to the sample before other tests are made.
(1) A musty odor is any odor that is earthy, moldy, or ground-like. Do
not confuse a burlap bag odor with a musty odor.
(2) A sour odor is any odor that is rancid, sharp, or acrid.
(3) A commercially objectionable foreign odor is any odor that is not
normal to rice and that, because of its presence, renders the rice
unfit for normal commercial usage (e.g., fertilizer, hides, oil
products, skunk, smoke, fire-burnt, and decaying animal and
vegetable matter odors).
(4) Fumigant or insecticide odors are not considered as commercially
objectionable foreign odors, unless they are caused by a fumigant
or insecticide that does not dissipate quickly. When a sample of
rice contains a fumigant or insecticide odor that prohibits a true
odor determination, the following guidelines must apply:
(a) The representative sample of rice must be allowed to air out
in an open metal container (e.g., a pan) for up to 4 hours, a
fume hood may be used if available; and
(b) If the fumigant or insecticide odor still prohibits the
determination of the rice’s true odor after 4 hours, the rice
must be considered as having a commercially objectionable
foreign odor. If the rice is from an unplacarded railcar, notify
your supervisor. Supervisors should report such instances
to FGIS headquarters.
Rice Inspection Handbook
Chapter 5: Milled Rice
August 2020
5-23
Caution: When sampling rice, check for placarded
railcars. If a car is placarded (or if a car is not placarded
but a fumigant odor is detected), do not enter the car or
sample the rice, and notify your supervisor immediately.
Note: Aromatic (scented) rice that has an odor known to
be common to such rice must be declared at the time of
the inspection request or will be considered as having a
commercially objectionable foreign odor.
c. When rice is determined to be musty, sour, or have a commercially
objectionable foreign odor, record the type of odor on the work record and
in the “RESULTS” section of the certificate, and grade the rice “U.S.
Sample Grade.”
Note: Milled Rice found to have a commercially objectionable
foreign odor is considered actionable according to FGIS Directive
9060.2, “Implementation of the FGIS-FDA Memorandum of
Understanding.”
5.16 HEATING
a. Determine heating on the basis of the lot as a whole.
(1) When high temperature develops in rice as the result of excessive
respiration, such rice is heating.
(2) Heating rice usually gives off a sour or musty odor.
(3) Care should be taken never to confuse rice that is warm due to
storage in bins, cars, or other containers during hot weather with
rice that is heating from excessive respiration.
b. When applicable, show the term, “Heating” on the work record and in the
“RESULTS” section of the certificate, and grade the rice “U.S. Sample
Grade.”

5.17 DISTINCTLY LOW QUALITY
a. Determine distinctly low quality on the basis of the lot as a whole or the
representative sample as a whole or an auxiliary sample.
b. Milled rice that is obviously affected by other unusual conditions which
adversely affect the quality of the rice and which cannot be graded
properly by use of the grading factors specified or defined in the standards
must be considered as being of distinctly low quality (see Chart 5.1 –
Distinctly Low Quality). Milled rice that contains any material too large to
enter a probe, Ellis cup, pelican, DT sampler or any official sampling
device such as pieces of wreckage and debris including lumps of rice,
grain, dirt and/or other commodities, unknown foreign substance or toxic
material which are visible to the sampler is considered DLQ.

the certificate, and grade the rice “U.S. Sample Grade.”
Note: Milled rice samples containing small stones may be
considered DLQ, depending on the quantity found on a percentage-
by-weight basis, and whether the condition adversely affects the
overall quality.
According to FGIS Directive 9060.2, “Implementation of the FGIS-
FDA Memorandum of Understanding,” milled rice is considered
actionable if stones constitute more than 0.1 percent-by-weight.

5.18 INSECT INFESTATION
a. Infested Milled Rice. Tolerances for live insects for infested milled rice are
defined according to sampling designation as follows:
Note: “Weevils” must include coffee bean weevils, broad-nosed
grain weevils, rice weevils, granary weevils, maize weevils, and
lesser grain borers. “Other live insects injurious to stored rice” must
include beetles, moths, meal worms, and other insects injurious to
stored rice.
Note: To aid in insect identification, refer to FGIS Visual Reference
Images (VRI) and/or the FGIS Stored-Grain Insect Reference.
b. Determine infestation on the basis of a representative portion of
approximately 500 grams, the lot as a whole (at the time of sampling,
while stationary or during checkloading/observation of loading), and/or the
component sample taken during continuous loading/unloading.
(1) Examine a representative portion.
(a) If no live or dead insects are found in the portion, make no
further check of the sample for insects.
(b) If two or more live or dead insects are found, consider the
rice to be “U.S. Sample Grade.”
(c) If one live or dead insect is found, divide out another
representative portion of approximately 500 grams from the
file sample. (Use the rest of the representative sample if the
file sample is less than 500 grams.)
1 If one or more live or dead insects are found in the
second portion, consider the rice to be “U.S. Sample
Grade.”
2 If no live or dead insects are found in the second
portion, do not consider the rice to be “U.S. Sample
Grade.”
(2) Examine the rice in the lot (i.e., the surface area of the lot and the
area around the lot).
(a) If no live or dead insects are found in, on, or about the lot,
make no further check of the lot for insects.
Rice Inspection Handbook
Chapter 5: Milled Rice
August 2020
5-26
(b) If two or more live or dead insects are found, consider the
rice to be “U.S. Sample Grade.”
(3) Examine the component samples
6
taken during continuous
loading/unloading.
(a) Divide out from each component sample a representative
portion of approximately 500 grams.
(b) Examine the representative portion for live or dead insects.
1 If no live or dead insects are found in the
representative portion, make no further check of the
component for insects.
2 If two or more live or dead insects are found, consider
the rice to be “U.S. Sample Grade.”
3 If one live or dead insect is found, cut another
representative portion of approximately 500 grams
from the component sample.
a If, in the second portion, one or more live or
dead insects are found, consider the rice to be
“U.S. Sample Grade.”
b If, in the second portion, no live or dead insects
are found, do not consider the rice to be “U.S.
Sample Grade,” and make no further check of
the component for insects.
c (Bulk rice only). If in the second portion no live
or dead insects are found, but one or more
insects had been found in a previously
inspected component in this or another sublot,
consider the rice that is represented by the
component sample to be “U.S. Sample Grade.”
6
As specified in Chapter 7, Roundlot Inspection. For shiplots and bargelots, a component sample may
not represent more than450,000 pounds of rice and each sublot must contain two or more approximately
equal-sized components.

5.19 TEST WEIGHT PER BUSHEL
Note: This factor is not provided for under the United States Standards for
Milled Rice, but may be determined upon request.
a. Determine test weight per bushel on a representative portion of
approximately 1,000 grams.
b. General Operating Procedures.
(1) Level and balance the test weight per bushel apparatus.
(2) Close the hopper valve.
(3) Pour the work sample into the hopper.
(4) Center the hopper over the kettle.
(5) Fill the kettle by opening the hopper valve quickly.
(6) Move the hopper all the way to the left before proceeding. Do not
jar the apparatus. Jarring could cause inaccurate results.
(7) Using a standard stroker, stroke the kettle by holding the stroker in
both hands with the flat sides in a vertical position. Level the rice in
the kettle by making three full-length, zigzag motions with the
stroker.
(8) Convert the weight of the sample by either the “standard” method
or one of the “alternate” methods.
(a) Standard Method. Carefully hang the kettle on the beam
and move the weights until the beam is balanced. Read the
test weight per bushel scale.
(b) Alternate Method – Manual Conversion. Pour the sample
from the kettle onto a general class scale, note the weight of
the sample, find the gram weight on the test weight
conversion chart (see Appendix 3, “Uniformity Tolerance
Tables”), and read the corresponding test weight per bushel
shown to the right of the gram weight.
Rice Inspection Handbook
Chapter 5: Milled Rice
August 2020
5-29
(c) Alternate Method – Automatic Conversion. When using an
electronic scale programmed to convert gram weight to
pounds per bushel select the appropriate test weight mode.
Place an empty sample pan or the test weight kettle on the
scale and zero the scale. Pour the sample from the kettle
into the sample pan or place the filled kettle onto the scale
as appropriate. Read the result from the test weight mode
selected.
c. Record the test weight per bushel on the work record to the nearest tenth
of a pound and record in the “RESULTS” section of the certificate.
d. Upon request by the applicant the following statement may be recorded in
the “REMARKS” section of the certificate:
“Test weight per bushel of (amount) pounds is approximately
equivalent to (amount) kilograms per hectoliter.”
Kilograms per hectoliter are determined by multiplying the test weight per
bushel by 1.287.
Note: Bulk density may be determined by dividing the test weight
per bushel by 1.2445. Bulk density is the number of pounds in one
cubic foot.

5.20 QUANTITATIVE ANALYSIS
a. Quantitative analysis provides an estimate of the quantity (percentage) of
whole kernels, second head-sized kernels, screenings-sized kernels, and
brewers-sized kernels in a lot or sample of milled rice.
Note: This factor is not provided for under the United States
Standards for Milled Rice, but may be determined upon request.
b. Definitions. The following definitions are applicable only to this
determination:
(1) Whole Kernels. Unbroken kernels of rice and broken kernels of rice
that are at least three-fourths of an unbroken kernel.
(2) Second Head Kernels. Broken kernels of rice and other material
that remain on top of a 6 sieve.
(3) Screenings Kernels. Broken kernels of rice and other material that
pass through a 6 sieve but remain on top of a 5½ sieve.
(4) Brewers Kernels. Broken kernels of rice and other material that
pass through a 5½ sieve.
c. Perform a milling analysis on long grain, medium grain, short grain, and
mixed milled rice as follows:
(1) Determine the percentage of “broken kernels (total)” on a
representative portion of no less than 25 grams. Remove the
broken kernels from the 25-gram portion using any device or
method that will facilitate the separation of the broken kernels from
the whole kernels.
(2) Determine the percentage of whole kernels by subtracting the
percentage of broken kernels from 100.0 percent.
Example: 100.0% - 19.6% TBK = 80.4% WK
(3) Calculate the adjusted base by dividing the percentage of whole
kernels in the sample by 100.
Example: 80.4% WK ÷ 100 = .80 adjusted base
(4) Determine the percentage of screenings kernels and brewers
kernels on a representative portion of approximately 125 grams.
Rice Inspection Handbook
Chapter 5: Milled Rice
August 2020
5-31
(a) Nest a 6 sieve on top of a 5½ sieve in a bottom pan.
(b) Place the sieves in a mechanical grain sizer and set the
timer to 20.
(c) Put the rice in the center of the top sieve and start the sizer.
Note: If a mechanical sizer is unavailable, hold the
sieves and bottom pan level and, using a steady motion,
move the sieves from right to left approximately 10
inches, and return from left to right to complete one
sieving operation. Repeat this operation 20 times.
(d) Return the material remaining in the perforations of the sieve
to the portion that remains on top of the sieve.
(e) Consider all material that passed through the 6 sieve, but
remains on top of the 5½ sieve, as screenings kernels. Do
not hand adjust the separation.
(f) Consider all material that passes through the 5½ sieve as
brewers kernels. Do not hand adjust the separation.
(5) Adjust the percentage of screenings and brewers by multiplying the
“actual” percentage of screenings and brewers by the adjusted
base.
Example: 2.1% SMR X .80 = 1.7% SMR
1.3% BMR X .80 = 1.0% BMR
(6) Determine the percentage of second head kernels by adding the
percentage of screenings and brewers kernels together and then
subtracting that total from the percentage of “broken kernels (total).”
Example: 19.6% TBK - (1.7% SMR + 1.0% BMR)
= 16.9% SHMR
(7) Record the percentage of whole kernels, second head kernels,
screenings kernels, and brewers kernels on the work record and in
the “RESULTS” section of the certificate to the nearest whole
percent.
d. Perform a milling analysis on second head, screenings, and brewers
milled rice as follows:
Rice Inspection Handbook
Chapter 5: Milled Rice
August 2020
5-32
(1) Determine the percentage of whole kernels on a representative
portion of no less than 25 grams. Remove the whole kernels from
the 25-gram portion by using any device or method that will
facilitate the separation of the whole kernels from the broken
kernels.
(2) Calculate the adjusted base by subtracting the percentage of whole
kernels from 100 percent.
Example: (100% - 13.1% WK) = 86.9
(3) Then divide the result by 100.
Example: 86.9 ÷ 100 = .87 adjusted base
(4) Determine the percentage of screenings kernels and brewers
kernels on a representative portion of approximately 125 grams.
(a) Nest a 6 sieve on top of a 5½ sieve in a bottom pan.
(b) Place the sieves in a mechanical grain sizer and set the
timer to 20.
(c) Put the rice in the center of the top sieve and start the sizer.
Note: If a mechanical sizer is unavailable, hold the
sieves and bottom pan level and, using a steady motion,
move the sieves from right to left approximately 10
inches, and return from left to right to complete one
sieving operation. Repeat this operation 20 times.
(d) Return the material remaining in the perforations of the sieve
to the portion that remains on top of the sieve.
(e) Consider all material that passed through the 6 sieve, but
remains on top of the 5½ sieve, as screenings kernels. Do
not hand adjust the separation.
(f) Consider all material that passes through the 5½ sieve as
brewers kernels. Do not hand-adjust the separation.
Rice Inspection Handbook
Chapter 5: Milled Rice
August 2020
5-33
(5) Adjust the percentage of screenings and brewers by multiplying the
“actual” percentage of screenings and brewers by the adjusted
base.
Example: 17.6% SMR X .87 = 15.3% SMR
71.6% BMR X .87 = 62.3% BMR
(6) Determine the percentage of second head kernels by adding the
percentage of whole kernels, screenings, and brewers kernels
together and then subtracting the total from 100.0 percent.
Example: 100.0% - (13.1% WK + 15.3% SMR +
62.3% BMR) = 9.3% SHMR
e. Record the percentage of whole kernels, second head kernels, screenings
kernels, and brewers kernels on the work record and in the “RESULTS”
section of the certificate to the nearest whole percent.

“reasonably well-milled”) must be equal to, or better than, that of the
Visual Reference Image for such rice.
b. Undermilled Milled Rice. Undermilled milled rice must be milled rice which
is not equal to the milling requirements for “hard milled,” “well-milled,” and
“reasonably well-milled” rice (see Section 868.306).
c. Grades.
(1) Grades U.S. No. 1 and U.S. No. 2 must contain no more than 2.0
percent of well-milled kernels.
(2) Grades U.S. No. 3 and U.S. No. 4 must contain no more than 5.0
percent of well-milled kernels.
(3) Grade U.S. No. 5 must contain no more than 10.0 percent of well-
milled kernels, no more than 10/0 percent of red rice and damaged
kernels (singularly or combined), and in no case more than 6.0
percent of damaged kernels.
(4) Grade U.S. No. 6 must contain no more than 15.0 percent of well-
milled kernels.
Note: The “Color and milling requirements” are not applicable
to the special grade “Undermilled milled rice.”
d. Basis of Determination. Determine milling degree on a representative
portion of approximately 250 grams.
e. Record the milling degree on the work record and in the “RESULTS”
section of the certificate.
(1) When rice is considered to be “Undermilled,” determine the
percentage of well-milled kernels on a representative portion of no
less than 25 grams (see section 5.33, “Well-Milled Kernels”) and
record the percentage of well-milled kernels on the work record and
in the “RESULTS” section of the certificate to the nearest tenth
percent.
(2) Except as provided above, all grades and grade requirements in
the “United States Standards for Milled Rice” must apply to
“Undermilled milled rice.”
Rice Inspection Handbook

5.22 COLOR
a. Basis of Determination. Color is usually determined by a cursory
examination.
When a detailed examination is necessary to determine color, make this
determination on a representative portion of approximately 250 grams of
milled rice.
b. Describe the color of the rice using one of the following terms:
White
Slightly Gray
Slightly Rosy
Creamy
Light Gray
Rosy
Gray
Very Rosy
Dark Gray
Note: When a sample has an overall yellowish cast or smut-affected
rough rice has a slight tinge of green, do not show color in the
“RESULTS” section of the work record. Show the following
statement in the “REMARKS” section of the work record and the
certificate: “This rice does not meet the color requirements for U.S.
No. 1 or 2 Milled rice.” The rice cannot be graded higher than U.S.
No. 3.
Note: Black rice typically has a deep purple to “rosy” colored
appearance once the bran has been removed. If the color of the
black rice appears “rosy,” it should receive a grade designation
consistent with that color (i.e., U.S. No. 5). However, should the
milled rice offered for inspection take on a different appearance that
is not addressed in the standards, do not show the color in results
section or the work record. Show the following statement in the
“REMARKS” section of the work record and the certificate: “This rice
does not meet the color requirements for U.S. No. 1 or 2 Milled rice,”
The rice cannot be graded higher than U.S. No. 3. For the special grade
Parboiled rough rice, color is not a grading factor. See section 5.37,
“Parboiled Milled Rice/Ungelatinized Kernels,” for special grade
determinations based on color level.
c. Record color on the work record and in the “RESULTS” section of the
certificate except as specified in the two notes above.

5.25 HEAT-DAMAGED KERNELS (VRI-R-2.0)
Definition. Whole or broken kernels of rice which are materially discolored and
damaged as a result of heating and parboiled kernels in nonparboiled rice which
are as dark as, or darker in color than, the interpretive line for heat-damaged
kernels. Visual Aid: Heat Damage (VRI R-2.0).
Note: Cold mold kernels are kernels of rice that are discolored by a
storage fungi which ranges from a light to dark amber/brown in color and
can be distinguished from other types of damage or heat damage by its
translucent appearance. Cold mold would generally function as damage;
however, if the color intensity meets or exceeds that depicted in Visual Aid:
Heat Damage (VRI R-2.0), it would then function as heat damage.
a. Determine the number of heat-damaged kernels on a representative
portion of 500 grams for all classes, except screenings and brewers milled
rice. (The United States Standards for Milled Rice does not provide for
determining this factor on screenings and brewers milled rice.)
(1) Divide out a representative portion of between 475 and 525 grams.
(2) Add or remove kernels (by finger pinching, not pouring) until exactly
500 grams is obtained.
b. Record the number of heat-damaged kernels on the work record and in
the “RESULTS” section of the certificate.
Note: If it is determined by general observation that the 500-gram
portion contains 75 or more heat-damaged kernels, divide the 500-
gram portion into two portions: (1) a 100-gram portion and (2) a 400-
gram portion. Examine the 100-gram portion for heat-damaged
kernels. If the 100-gram portion contains 25 or more heat-damaged
kernels, multiply the number of kernels found by 5 and record that
number of heat-damaged kernels on the work record. But if the 100-
gram portion contains less than 25 heat-damaged kernels, examine
the 400-gram portion and add the number of heat-damaged kernels

5.27 RED RICE AND DAMAGED KERNELS
a. Definitions.
(1) Red Rice. Whole or broken kernels of rice on which there is an
appreciable amount of red bran.
(2) Damaged Kernels. Whole or broken kernels of rice which are
distinctly discolored or damaged by water, insects, heat, or any
other means, and parboiled kernels in nonparboiled rice. “Heat-
damaged kernels” must not function as damaged kernels.
b. Basis of Determination. Determine red rice and damaged kernels on a
representative portion of no less than 25 grams for all classes, except
screenings and brewers milled rice.
(1) For screenings and brewers milled rice, determine the percentage
of “heat-damaged kernels, kernels damaged by heat, and/or
parboiled kernels in nonparboiled rice,” on a representative portion
of no less than 25 grams and determine “badly damaged or
extremely red in appearance” on a representative portion of
approximately 1,000 grams.
(2) Red rice is rice that has a streak of red bran one-half or more the
length of the kernel, or two or more streaks that total one-half or
more the length of the kernel. A kernel or a piece of kernel of rice
that does not have sufficient red bran to be considered as red rice
must be considered as long grain, medium grain, or short grain rice,
as appropriate.
Note: Black rice would function as red rice. Black rice is rice
that has a streak of black bran one-half or more the length of
the kernel, or two or more streaks that total one-half or more
the length of the kernel. A kernel or piece of a kernel that does
not have sufficient black bran to be considered as red rice will
be considered as long grain, medium grain, or short grain as
appropriate and could function as other types.
c. Types. The major types of damaged kernels are as follows:
(1) Insect-Bored Kernels.
Whole or broken kernels of rice that have been bored by insects.
Kernels that are only slightly eaten by insects and are clean in
appearance must be considered as sound kernels.

Standards for Brown Rice for Processing, but may be
determined upon request.
(4) Parboiled Rice in Nonparboiled Rice.
Whole or broken kernels of parboiled rice in nonparboiled rice that
are lighter in color than the Visual Aid: Heat Damage (VRI R-2.0).
(5) Other Damaged Kernels.
Whole or broken kernels of rice that are distinctly discolored or
damaged from causes other than those listed above will be
considered as damaged kernels. However, those whole and
broken kernels that show sheller marks, but are otherwise not
distinctly discolored or damaged, will not function as damaged
kernels.

Lightly tap the bottom of the plates to remove material retained in
the perforations of each plate. Keep the material removed by each
plate separate.
(5) Hand adjust the material that lodges in the plates to remove any
whole kernels, any broken kernels that obviously do not belong with
the 5 or 6 plate brokens, any seeds, and any foreign material.
d. For western production rice:
(1) Mechanical Sieving Method.
(a) Mount a 6 sieve with a bottom pan on a mechanical sieve
shaker.
(b) Make sure the shaker and sieve are level.
(c) Set the stroke counter for 20 strokes
(d) Gently pour the representative portion of rice in the center of
the sieve.
(e) Turn the machine on.
(f) After the required number of strokes has been completed,
the machine will automatically stop.
(g) Carefully remove the sieve and bottom pan. Jarring the
sieve will cause the material remaining on top to pass
through the perforations, leading to inaccurate results.
(h) Combine the material lodged in the perforations with the
material that remained on top of the sieve. To remove the
lodged material from the perforations, rub the sieve bottom
gently. Tapping will warp the sieve and lead to inaccurate
results in future determinations.

5.41 FORTIFIED MILLED RICE
Note: This factor is not provided for under the United States Standards for
Milled Rice but may be determined upon request.
The rice fortification technique consists of spraying several layers of a mineral
and vitamin premix onto the surface of rice kernels to form fortified kernels. This
rice is then blended with non-fortified rice at a predefined dilution to produce
fortified rice.
The extruded rice fortification is a mixture of rice flour, mineral and vitamins
extruded to produce a kernel which mimics the physical characteristics of rice.
The fortified kernels are then blended with non-fortified rice, typically at a 1:100
ratio. Since the micronutrients are inside the extruded kernels, they cannot be
rinsed out of the rice. Broken extruded kernels do not count toward broken
kernels of rice since they are not rice kernels.
Upon the applicant’s request, official personnel can count the number of fortified
kernels in a representative sample of 200 kernels. A letterhead statement can be
issued with the following statement: “FGIS personnel identified fortified kernels in
a representative sample of 200 kernels of milled rice.” This statement cannot be
added to an official inspection certificate.
Note: If an applicant requests an inspection for non-fortified milled rice
and coated or extruded kernels are present, they will function as foreign
material. If the amount of foreign material exceeds 0.1%, the sample will
grade as “U.S. Sample Grade.”
A sample of just the extruded rice will be considered a processed commodity.
a. Basis of Determination. Fortification in Milled Rice is determined using the
Prussian Blue Method for Iron Enrichment, as outlined in the below
procedure.
b. Procedure. If an applicant requests testing for fortification (coated or
extruded), analyze 500 grams and certify the results according to the
procedure listed below:
Note: A fume hood is not required for conducting this test; however,
ensure that you are in a well-ventilated area.
(1) From the 500-gram (heat/seed) portion remove at least 15 coated
or extruded kernels (approximately 1 gram.)

(2) Use the sample scoop (1/4 teaspoon) to transfer about 1 gram of
the un-enriched rice reference sample to the first spot plate well
(left).
(3) Place the 15 selected kernels in the middle porcelain spot plate
well.
(4) Use the sample scoop to transfer about 1 gram of the enriched rice
reference sample to the third spot plate well (right).
(5) Wearing gloves, add three drops of the Hydrochloric Acid to each of
the wells containing sample. Wait ten minutes and then add three
drops of Potassium Ferrocyanide to each of the wells that were
treated with Hydrochloric Acid solution.
(6) Wait ten minutes for the color to develop.
(7) Compare the color of the test sample to the color of the un-enriched
and enriched rice reference samples.
(8) Test samples containing fortification should produce a blue color
similar to that of the enriched rice reference samples and are
considered positive.
(9) Test samples that do not contain fortification should produce color
similar to that of the un-enriched reference sample and are
considered negative.
(10) Four test samples can be tested on a spot plate (with two reference
samples per test sample).
(11) After testing, discard rice in the spot plate wells and clean the spot
plate.
Figure 5.4 – Spot Plate for Prussian Blue Method for Iron Enrichment in
Rice displays an example of a spot plate that is used for testing. The first
well (1) in the spot plate should contain the un-enriched rice reference
sample, the middle well (2) should contain the test sample, and the third
well (3) should contain the enriched rice reference sample.

5.42 TOTAL OIL AND FREE FATTY ACID
Note: This factor is not provided for under the United States Standards for
Milled Rice but may be determined upon request.
Caution: Conduct this test in a well-ventilated area.
For reference, see “Equipment and Chemicals for Total Oil and Free Fatty Acid
Analyses,” at the end of this chapter.
a. Determine total oil and free fatty acid on a work sample of approximately
650 grams.
b. Divide out a 650-gram representative portion and determine the moisture
content. Record this information on the Total Oil and Free Fatty Acid
Worksheet (work record) and in the “RESULTS” section of the certificate
to the nearest tenth percent.
c. Divide the remainder of the work sample to no less than 15 grams. Grind
the sample portion as follows:
(1) Turn on the grinder and allow it to reach maximum RPM.
(2) Adjust the feed gate to provide a feed rate of approximately 2
grams per second.
(3) Pour the sample into the feed hopper and allow it to grind.
(4) Press the plunger three to five times and tap above the clear plastic
cyclone to clear the grinder of all loose flour.
(5) Hold the plunger down, remove the sample jar, and cap it.
(6) Shake and rotate the sample jar to loosen caked flour from the
sample jar.
(7) Lightly clean the grinder with a brush after each sample. If
practicable, also vacuum the grinding chamber.
d. Extract the oil from the rice as follows:
Note: Prior to beginning the procedure, turn the analytical balance
on and allow at least 30 minutes to warm up. Calibrate it by
following the manufacturer’s instructions and then verify its
accuracy using a 10-gram, Class S weight.
Rice Inspection Handbook
Chapter 5: Milled Rice
August 2020

(1) Make sure the extraction beaker is clean and dry.
(2) Clean and dry your hands or wear clean plastic or rubber gloves.
This is to limit the transfer of dust and oil from hands to extraction
beaker, filter paper, or extraction thimble.
(3) Weigh
7
the extraction beaker on an analytical balance to the
nearest 0.0000 g and record the weight on the worksheet. Handle
the extraction beaker only at the top, with your forefinger and thumb
or with gloved hands. Handle the beaker as little as possible to
limit the transfer of oil from your hands to the beaker.
(4) Place filter paper or a weighing dish on the analytical balance and
tare off its weight.
(5) Mix the ground sample in the sample bottle with the spatula. Place
10 grams (+ .02 grams) of ground sample on the filter paper or
weighing dish and record the net weight on the worksheet.
(6) Pour the sample into the extraction thimble and plug with
nonabsorbent cotton; or place sample on filter paper, fold the filter
paper tightly with the sample inside, and then place it in the
extraction thimble.
Note: Before its initial use, wash the nonabsorbent cotton
with petroleum ether.
(7) Turn on the fan in the fume hood. Start the cold water running
through the cooling chamber.
(8) Place the thimble with the sample into the open ended Goldfisch
tube and lock it into place on the extractor.
8
To extend the life of
the heating elements, run two, four, or six samples at a time. Turn
off the heating elements not being used.
Note: Steps 9 through 19 must be performed inside the fume
hood by a technician who is wearing non-absorbent gloves
and appropriate eye protection. Strict adherence to the
following procedures is essential.
7
When using an analytical balance, the balance’s doors should be closed and the balance allowed to
stabilize before recording the weight.
8
The main power switch to the Goldfisch fat/oil extractor should be turned off before: (1) raising or
lowering the heating elements; (2) changing the heating selector switch; or (3) putting extraction beakers
up or taking them down.
Rice Inspection Handbook
Chapter 5: Milled Rice
August 2020
5-66
(9) Add approximately 50 ml of petroleum ether into the weighed
extraction beaker. Cover one of the heating elements on the
extractor with a heating element cover.
(10) Attach the extraction beaker to the extractor with the attachment
ring and tighten well. Remove the heating element cover.
(11) Raise the heating element to the bottom of the beaker and extract
for 2½ hours at the standard heat setting (approximately 8). Begin
the 2½-hour period when the first drop comes through the open-
end tube.
Note: The standard heat setting should yield approximately
150 drops per minute of petroleum ether from the bottom of
the open-end tube, depending on the proximity of the heating
element to the bottom of the beaker. Adjust the dial and/or
height of the heating element to yield this amount.
(12) After starting, check to see if petroleum ether is escaping from the
system. When the petroleum ether starts to boil, the level of
petroleum ether in the beaker will drop. This drop is because some
of the petroleum ether is in a gaseous state. After the initial drop, if
the level continues to drop, then there is a leak in the system.
Lower the heating element, re-tighten the ring, raise the heating
element, continue extracting, and recheck for escaping petroleum
ether.
(13) Check the petroleum ether for cloudiness. If cloudy, rice particles
have infiltrated the petroleum ether. Stop the procedure and
determine if the rice particles came from an improperly seated
cotton plug, from a leaking thimble, or from rice particles on the
outside of the thimble. Start the procedure over with a new sample
portion and make the proper corrections.
(14) Make sure that water condensation on the cooling chamber does
not drip onto the heating element or drip into the beaker when it is
released.
(15) At the end of the extraction period, turn off and lower the heating
element. Release vacuum in the beaker by pulling the tab on top of
the extractor. Cover the heating element with a heating element
cover. Release the beaker, remove the open-end tube with the
sample and replace it with the closed- end tube, reattach the
beaker, remove the heating element cover, raise the heating
element, and heat the beaker to collect any excess petroleum
ether.
Rice Inspection Handbook
Chapter 5: Milled Rice
August 2020
5-67
(16) Remove the thimble from the open-end tube. Place the thimble
with the sample in the fume hood to dry. After drying, remove the
filter paper with the rice (or cotton and rice) from the thimble, save
the thimble and cotton for future extractions. Throw rice and filter
away.
(17) When the level of petroleum ether in the extraction beaker reaches
about 1/8 inch, turn off and lower the heating element. Place the
heating element cover over the heating element, release the
vacuum, and release the beaker.
(18) Remove and empty the closed-end tube into the used petroleum
ether container or dispose of the used petroleum ether by letting it
evaporate in the fume hood. Do not turn the fume hood fan off until
all petroleum ether has evaporated, and sufficient air has been
used to flush the fumes from the fume hood exhaust system.
(19) Evaporate the remaining petroleum ether in the extraction beaker
by placing the beaker in the front part of the fume hood with the
door to the fume hood lowered to a level just above the beaker’s
top. When the beaker appears to be free of ether, place it upright
on the heating element cover that is on the element for a few
seconds to assure that all remaining ether is removed. (Be careful
not to allow oil to char.) Remove the extraction beaker from the
element cover and let the beaker cool in the fume hood to room
temperature.
(20) Weigh the cool, dry extraction beaker and record the weight on the
worksheet.
e. Determine the amount of free fatty acid as follows:
(1) Using a crystallizing dish and a magnetic stirrer-hot plate, heat a
water bath to 60-65˚ C.
(2) Prepare a titration solvent as follows:
(a) Place 25 ml of alcohol reagent - specially denatured
anhydrous ethyl alcohol - in a 250-ml beaker.
(b) Add 1 ml of phenolphthalein with the pipet to the alcohol.
(c) Place the beaker in the hot water bath and warm the titration
solvent. Add a stirring bar to the beaker and start it stirring.
Rice Inspection Handbook
Chapter 5: Milled Rice
August 2020
5-68
(d) Using the buret, titrate with 0.02 N Sodium Hydroxide
(NaOH) slowly, one drop at a time, into the titration solvent
until a faint pink color persists.
Note: Larger amounts of titration solvent may be
prepared provided the ratio is the same (e.g., 75 ml
alcohol to 3 ml of phenolphthalein). Unused solvent
must be stored in a tightly sealed container and used
within 2 days.
(3) Add 10 ml of the titration solvent with the pipet to the residue in the
extraction beaker. Rinse the sides of the beaker while adding the
titration solvent.
(4) Place the extraction beaker in a hot (60-65˚ C) water bath and let
the temperature stabilize, then add the stirring bar and start stirring.
(5) Zero the buret with NaOH and titrate the sample until a faint pink
color persists for at least 1 minute.
(6) Determine the amount of NaOH titrated and record it on the
worksheet. Record the amount to the nearest one hundredth of a
milliliter.
(7) Empty the contents of the extraction beaker down the drain with a
large amount of water. Carefully wash the extraction beaker with
soap and water making sure all oil residue is removed. Rinse the
beaker with distilled water. Cover the beaker with a towel to help
keep it clean and let it air dry.
(8) Should the buret or stopcock become plugged with crystallized
NaOH or foreign material, clean them with distilled water and let
dry. If water is present in the buret, rinse it with NaOH before
using.
f. Calculate the percentage of total and free fatty acid as follows:
(1) Percentage of Total Oil, Moisture-Free Basis (TODB).
(Wt. of Beaker with Oil Residue - Tare Wt. of Beaker) X 10%
= % Total Oil
(% Total Oil ÷ (100 - % Moisture)) X 100 = % TODB
Example: (69.1003 - 69.0244) X 10 = 0.759 or 0.76%
(0.759 ÷ (100 - 11.9)) X 100 = 0.862 or 0.86%
Rice Inspection Handbook
Chapter 5: Milled Rice
August 2020
5-69
Record the percentage of Total Oil, Moisture-Free Basis (TODB) on
the word record and in the “RESULTS” section of the certificate to
the nearest whole percent.
(2) Percentage of Free Fatty Acid in Oil (FFA/O).
Normality of NaOH Titrate X ml of NaOH Used in Titrating X 28.2 ÷
(Weight of Beaker with Oil Residue - Tare Weight of Beaker)
= % FFA/O
Example: 0.0202 X 3.25 X 28.2 ÷ 0.0759 = 24.4 or 24%
Record the percentage of Free Fatty Acid in Oil (FFA/O) on the
word record and in the “RESULTS” section of the certificate to the
nearest hundredth percent.
(3) Percentage of Free Fatty Acid in Sample (FFA/S).
% TODB X % FFA/O ÷ 100 = % FFA/S
Example: 0.862 X 24.4 ÷ 100 = 0.212 or 0.21%
Record the percentage of Free Fatty Acid in Sample (FFA/s) on the
word record and in the “RESULTS” section of the certificate to the
nearest hundredth percent.
g. Maintain a file sample of at least 300 grams of whole rice on each sample
analyzed for TOFFA. Keep file samples in a refrigerator at approximately
40˚ F.

(3) The same certificate number as shown on the superseded
certificate will show a consecutively numbered suffix on each
divided-lot certificate (e.g., US-NOFO-2001764, US-NOFO-
2001764).
(4) The rice quantity for each divided-lot must be requested on the
application. No divided-lot certificate will be issued which shows,
individually or collectively, a rice quantity in excess of the quantity
shown on the superseded original certificate.
(5) At the request of the applicant, a separate consignee, load order
number, purchase authorization number, reference number,
contract number, letter of credit identification, or similar
identification may be shown on each divided- lot certificate. This
information must be furnished by the applicant, in writing, and
identical information must be shown on the superseded certificate
Note: It is not necessary to list the individual sets of
information on the original master certificate, when you have
not formally issued it to the applicant, because you will void
the original master certificate for a divided-lot certificate(s)
and eventually list all the requested sets of information on
each individual divided-lot certificate. However, you must still
include all other required information (e.g., factor results,
statements) on the original master certificate.
(6) The markings on packaged rice containers will be shown according
to procedures in section 6.12, “Container Markings Information,” of
this chapter. The markings shown on the superseded certificate
must be shown on each divided-lot certificate with the number of
containers for each marking.
i. If checkweighing is performed as part of the original inspection, the
estimated average gross, tare, and net weights determined during the
original service must be used to determine the estimated total gross, tare,
and net weights to be shown on the divided-lot certificate. To certify
checkweighing, you may use a “Rice Inspection Services Certificate”
(Official White Certificate).
(1) If an inspection certificate is issued in addition to a separate
checkweighing or official weight certificate, do not include the
weighing information on the inspection certificate.
Rice Inspection Handbook
Chapter 6: Certification
August 2020
6-7
(2) If a separate checkweighing or official weight certificate is issued,
show the same type and class of rice as shown on the official
inspection certificate. Do Not show U.S. Grade. For example, if
the inspection certificate was issued for US #2 Long Grain Milled
Rice, use Long Grain Milled Rice for the commodity on the weight
certificate.
j. When a rice bag lot is not required to be checkweighed or in the case of a
bulk lot which is not officially weighed (e.g., barge, trucks, containers),
obtain the estimated net weight of the lot in writing from the applicant.
Show the estimated net weight of the lot in the Quantity section and enter
"Vendor's Weight” on the certificate in the “REMARKS” section.
k. If an applicant requests a divided-lot certificate, each certificate must
contain the same information and statements as the original certificate and
the vendor weights must add up exactly to the original weight.
l. After divided-lot certificates have been issued, further dividing or
combining is prohibited except with the approval of the FGIS Deputy
Administrator. These limitations do not apply when a corrected certificate
must be issued.

6.5 PARTIAL INSPECTION CERTIFICATE
a. There may be circumstances when the entire lot is not accessible, or a
representative sample cannot be obtained. In such instances, official
personnel will provide information on the work record stating the estimated
quantity of the rice in the accessible portion and that the inspection is
limited to the accessible portion. The inspection certificate issued must
have the words “PARTIAL INSPECTION” conspicuously shown in the
“REMARKS” section of the certificate.
b. For bulk rice in bins and shipholds that are sampled by a 12-foot probe
that does not reach the bottom of the lot, a partial inspection certificate
must be issued. Show the following statement in the “REMARKS” section
of the certificate:
“Top feet sampled. Bottom not sampled.”
Note: Do not issue a partial inspection certificate for bulk rice in
hopper cars or barges that are sampled using the approved length
probe (see section 2.13(a)) that does not reach the bottom of the lot
when fully inserted. The statement “Top feet sampled. Bottom
not sampled.” must be shown in the “REMARKS” section of the
certificate.
c. Bulk or bagged rice offered for inspection at rest in a container loaded in
such a manner that it is only possible to secure a door-probe, mustow-
probe, door-bag-probe, or surface-bag-probe sample(s) of the lot, or the
rice is not trimmed, or otherwise does not have a reasonably level surface,
the carrier or container will be considered to be “heavily loaded” and a
partial inspection certificate issued.
(1) If a partial inspection is made, the inspection certificate issued must
have the words “PARTIAL INSPECTION” conspicuously shown in
the “REMARKS” section of the certificate.
(2) In addition, the certificate must show the type of sample(s)
obtained. The type of sample(s) will be described as “door-probe,”
“mustow-probe,” “door-bag-probe,” or “surface-bag-probe” sample
and shown in the “REMARKS” section of the certificate. In the case
of packaged rice (including bagged rice), the approximate number
of containers accessible for sampling and the approximate number
of containers in the lot must be shown in the “REMARKS” section of
the certificate. (e.g., “800/100-pound polypropylene bags, part of
an undivided lot of 1,250 bags.”)

6.6 CORRECTED CERTIFICATE
a. The accuracy of the statements and information shown on official
certificates must be verified by the individual whose name or signature, or
both, is shown on the official certificate, or by the authorized agent who
affixed the name or signature, or both. Errors found during this process
will be corrected according to this section. The term “errors” includes
errors of commission or omission and are not limited to errors of
commission or omission attributed to official personnel. Such errors may
be attributed to the applicant for inspection.
b. Only official personnel may make corrections, additions, or other changes
to official certificates.
c. If errors are found on an official certificate at any time up to a maximum of
1 year after issuance, the errors must be corrected by voiding the incorrect
certificate and issuing a corrected certificate. A corrected certificate must
be issued superseding the incorrect one.
(1) Written or verbal notice of error may be issued to the applicant and
respondents.
(2) The original of the incorrect certificate must be “Voided.”
(3) The original and the copies of the corrected certificate must be
issued to the same applicant and respondents who received the
certificate found incorrect.
(4) The corrected certificate must show the identical information and
statements as shown on the incorrect certificate except the
following:
(a) The correct statement or information must be shown instead
of the incorrect or omitted statement or information.
(b) The corrected original certificate must show the term
“Corrected Original” and the corrected copies must show the
term “Corrected Copy.”
(c) The original and the copies must show in the “REMARKS”
section, the following complete statement:
Rice Inspection Handbook
Chapter 6: Certification
August 2020

“This certificate is corrected as to (reason for
correction) and supersedes Certificate No.
(superseded certificate number), dated (date of
superseded certificate). The superseded certificate
has not been surrendered and is no longer valid for
commerce.”
Official personnel must exercise other such precautions as
may be necessary to prevent the fraudulent and
unauthorized use of the superseded certificate.
Note: This statement is required even when the voided
certificate has not been released.
(d) A new certificate number must be shown.
(5) The provisions of this section must be applicable to all types and
levels of inspections.
6.7 MULTIPLE GRADE CERTIFICATE
a. When rice is offered for inspection as one lot and is subsequently found to
contain portions that are distinctly different in class/type, quality, or
condition, the rice in each portion must be sampled, inspected, and
graded separately, but the results must be recorded on one certificate.
b. The certificate must include the approximate quantity or weight of each
portion, the location of each portion in the carrier, and the grade and factor
information on the rice in each portion.
(1) Enter an estimate of the quantity of the larger portion and the grade
of that portion on the certificate in the “RESULTS” section and the
grade line of the certificate. Enter an estimate of the remainder of
the lot, factors, and the grade assigned to that portion in the
“REMARKS” section of the certificate. For hopper cars, include the
identification of the compartment(s).
(2) Factor information must be entered in the same order as the factors
listed in the results section of the certificate and must be related to
a particular portion and its position in the carrier.
Rice Inspection Handbook
Chapter 6: Certification
August 2020

6.8 INSPECTION DATE INFORMATION
a. The inspection date (or date of service) is the day on which the final
service is completed as shown in the detailed work records.
Note: If multiple services are performed, the date shown on the
certificate must be the day the last service was performed.
b. A uniform lot which requires more than one day to sample, may be
certified as one lot, provided no undue delay occurs in completion of the
lot.
(1) There must be a reasonably continuous operation taking into
consideration weather and other conditions which might interfere in
the completion of the lot.
(2) If reasonably continuous inspection service is not maintained, one
lot inspection certificate must be issued for the portion inspected
prior to the break in inspection service, and one lot inspection
certificate must be issued for the portion inspected after the break
in inspection service (or after each additional break).
(3) “Reasonably continuous inspection service” may include inactive
periods of no more than 88 consecutive hours (including weekends
and holidays). For roundlot or warehouse lot inspection plan
purposes, at least one block or sublot must be inspected during the
prescribed time period. The 88-hour limit may be extended at the
discretion of the appropriate FGIS field office manager.
c. Divided-lot certificates must be dated the same date as shown on the
original certificate.

6.9 REMARKS INFORMATION
a. The “REMARKS” section is for showing information which will facilitate
marketing. No statement may be shown which is known to be false or
misleading. Remarks may include information, such as warehouse receipt
numbers, loan numbers, load order numbers, container markings, seal
numbers, and approved statements.
b. If an applicant requests that any factor information be shown differently
than the standard (e.g., portion size, count, percent), you must show that
factor information in the “REMARKS” section of the certificate. (e.g.,
Number of Damaged by Heat kernels in 500 grams; Heat damaged
kernels shown in percent).
Note: All lots that receive a US grade determination must be graded
according to U.S. Standards and results shown in the “RESULTS”
section of the certificate.
c. Additional page(s) of certificates may be used for showing pertinent
information and approved statements. When information requires more
than one page, the following must be shown:
(1) The statement “Continuing: Page 1 of [Y]” must be shown on the
first page and report the total number of pages
(2) The statement “Continuing: Page [X of Y]” must appear at the top of
each subsequent page to document page number and total number
of pages
Note: Requests for special statements which are substantially
different from approved statements or which are not approved,
must be referred to the appropriate FGIS field office manager
for approval.

6.10 SHIPPER AND CONSIGNEE INFORMATION
Rice certificate forms do not have a preprinted space for showing the name and
address of a shipper or consignee. This information may be shown in the space
provided for remarks. Showing this information is not mandatory, it will only be
shown when requested.
Note: When divided-lot inspection certificates are requested with different
consignees for each divided-lot certificate, all consignees must be shown
on the surrendered original certificate.
Note: It is not necessary to list the individual sets of information on the
original master certificate, when you have not formally issued it to the
applicant, because you will void the original master certificate for a
divided-lot certificate(s) and eventually list all the requested sets of
information on each individual divided-lot certificate. However, you must
still include all other required information (e.g., factor results, statements)
on the original master certificate.
6.11 CARRIER, CONTAINER, AND LOT IDENTIFICATION
a. Carrier, container, lot and seal identification may be shown on lot
inspection certificates and on submitted sample inspection certificates.
b. Care should be taken to ensure that the proper identification information is
recorded.
c. For lot inspections, official personnel must provide identification
information on the work record. Do not transcribe the information from the
application or other documents supplied by the applicant or others.
Note: In certain instances, it may be necessary to separately certify
the rice in one or more compartments of a hopper car because of
different class, quality, or condition. A statement identifying the
compartment must be shown after the car initials and number and
must be followed by the seal identification applied to the
compartment, if applicable.
Rice Inspection Handbook
Chapter 6: Certification

6.12 CONTAINER MARKINGS INFORMATION
Most packaged rice has identifying marks on the containers. These marks are
required to be shown on the rice inspection certificate if the marks indicate a
different quality of rice than what is actually in the container. All other times, the
marking may be shown upon request of the applicant. Show such markings on
certificates as follows:
a. Uniform Markings.
(1) When container markings are uniform for an identified rice lot, then
all markings may be shown on the certificate.
(2) However, much of the markings shown on the containers is
information which identifies the container manufacturer or some
container specification and does not serve any useful purpose with
regard to identifying marks. Such information, unless requested by
the applicant, need not be shown as identifying marks on the
certificate.
(3) Markings are usually shown in lines one above the other
substantially, as follows:
RICE
PRODUCT OF U.S.A.
EXTRA FANCY
LONG GRAIN
888
SAM, INC.
STUTTGART, AR
(4) Space permitting, such markings may be shown on the certificate
as shown above but are usually shown with slash marks indicating
the end of each line of markings, as follows:
RICE/PRODUCT OF U.S.A./EXTRA FANCY/LONG
GRAIN/888/ SAM, INC./STUTTGART, AR
b. Nonuniform Markings.
(1) On some occasions, an identified rice lot will have varied markings
shown on the containers. Such markings are usually the result of
the use of “leftover” containers accumulated and used by a shipper
at the end of a shipping season.
Rice Inspection Handbook
Chapter 6: Certification
August 2020
6-15
(2) When such marks are found and the applicant does not request
that such marks be shown, the statement “No Common Marks” may
be shown in the “REMARKS” section of the certificate.
(3) If the applicant requests that such varied markings be shown, the
applicant has the responsibility of separating the containers by the
various markings so that the number of containers of each marking
can be determined or the applicant can furnish the count.
c. Nonuniform Markings - With Uniform Sublot Markings.
(1) There are occasions when several sublots, with uniform markings
within each sublot but varying markings from each other, will be
accumulated in warehouses and designated as one overall lot.
(2) In such instances, a record will be kept of the number of bags of
each set of uniform markings contained within the overall lot. Such
information may be shown in the “REMARKS” section of the
certificate.
For Example: An identified warehouse lot consisting of 10
separate cars (1,200 100-pound bags each)
was unloaded on a warehouse floor. Six of the
carlots have one set of uniform markings and
four of the carlots have another set of uniform
markings. The certificate (with regard to
markings) would be issued as follows:
7,200 bags marked: RICE/Product of U.S.A./Jones Rice
Co./Eunice, LA/(Reverse) LARENCO MARQUES
4,800 bags marked: RICE/Product of U.S.A./Smith Rice
Inc./Houston, TX/ (Reverse) LARENCO MARQUES
d. Tag Markings. When containers are tagged with identifying markings, the
tag information may be shown in the space provided for remarks on the
certificate as follows:
Example: EXPORT/RICE/SOUTH AFRICA/LONG GRAIN
e. Contract Specification Markings. An applicant may request that the
markings be checked only for compliance with contract specifications. In
such cases, show in the “REMARKS” section of the certificate, one of the
following statements:
Rice Inspection Handbook
Chapter 6: Certification
August 2020
6-16
(1) “Bag markings as specified by (contract number, agency, or other
pertinent information).”; or
(2) “Bag markings not as specified by (contract number, agency, or
other pertinent information) because (reason; e.g., code number
omitted or letter size incorrect).”
f. Registered Trademark Markings.
(1) Many rice companies, exporters, and shippers have registered
trademarks (i.e., brand names) for rice packaged by or for them.
Such markings may contain artwork, such as an eagle, crossed
rifles, a plantation home, and many other markings which frequently
are not necessary, practicable, or requested by the applicant.
(2) When such instances occur and all of the brand name information
is not needed or requested by the applicant, the brand name may
only be shown in parenthesis followed, if necessary, by any export
marks shown on the reverse of the bag. In such cases, show on
the work record and in the “REMARKS” section of the certificate as
follows:
Example: (Eagle Brand) (Reverse) XYC/RICE/SOUTH
AFRICA/LONG GRAIN
6.13 LOCATION INFORMATION
a. The space identified as “LOCATION” is provided to show the city and
state where an inspection is performed. The place of inspection (e.g., rice
mill, warehouse, or wharf) may also be shown.
b. Applicants for inspection may request that the place of inspection not be
shown. This request is frequently made by rice exporters or their
representatives who may enter into purchase contracts with several rice
facilities to fulfill a sales contract commitment for a larger export cargo
shipment. In such instances, the place of inspection is not needed by the
applicant, would not facilitate efficient and orderly marketing of the rice,
and is not required to be shown. However, the place, city, and state
where the inspection was performed must be shown on all inspection work
records and certificates.
Rice Inspection Handbook
Chapter 6: Certification
August 2020
6-17
6.14 QUANTITY INFORMATION
a. On lot inspection certificates, the space identified as “QUANTITY” is
provided to show the quantity of rice in the lot that is inspected.
(1) The rice lot quantity must be stated in terms of Bargelot, Bushels,
Carlot, Container lot, Grams, Metric Tons, Trucklot, or in Pounds or
by container type and capacity and whether the rice is in bulk or
bagged. (Totes are considered “bagged.”)
Note: The statement of quantity serves as a part of the lot
identity and is not to be construed as a certificate of weight or
quantity, except when the applicant requests that a lot of
packaged/bagged rice be checkloaded, checkweighed, or
checkcounted and the certificate so states. The weight
provided by the vendor will not be shown in the “Quantity”
section of an official certificate. Vendor’s weight must be
reported in the “REMARKS” section of the certificate using the
following statement:
“Vendor’s Weight: ______ pounds.”
(2) Typical statements of quantity shown on the work record and in the
“REMARKS” section of the certificate are as follows:
(a) 1,000 100-pound, double polypropylene bags 1,000 50-
kilogram new jute bags
(b) 1,000 110.23-pound bags (50 kilograms) or (50 kilos)
(c) 55,000 100-pound bags
(d) 1 carlot (bulk)
(e) 1,000,000 pounds (bulk)
(f) 2 bargelots (bulk) 1,760,000 pounds
(g) 875 48-pound paper balers (24/2-pound poly bags)
(h) 1,000 30-pound cases of 30/1-pound polyethylene bags
(i) 8,400 99.3-pound bags (100 pound gross)

6-18
Note: When a lot of rice if officially weighed, the results
must be issued on a “Commodity Weight Certificate”
(FGIS-7).
b. On submitted sample inspection certificates, the space provided for
quantity must be used to show the approximate sample quantity in terms
of weight or volume. No submitted sample inspection certificate will be
issued which shows, directly or indirectly, the quantity of rice in the lot
from which the sample may have been taken.
6.15 FACTOR INFORMATION
a. Each official certificate will show the class, grade, and any other quality
designation according to the United States Standards for Rice, all factor
information requested by the applicant, and all grade determining factors
for rice graded below U.S. No. 1. (The milling degree must also be shown
for graded milled rice.)
Note: A factor must be considered a quantified physical or chemical
property identified in official standards, specifications, information
abstracts, contracts, or other documents whose measurement
describes a specific quality of a commodity.
b. Factor information must be shown on the certificate.
(1) Show factor information on lot inspection certificates by selecting
the factor followed by the appropriate percentage, count, or other
quality descriptions.
(2) Show factor information on submitted sample inspection certificates
by selecting the factor followed by the appropriate percentage, the
count, or other quality descriptions.
Note: Total Rice and Whole Kernel results for Milling Yield
determinations must be inserted in the “RESULTS” section of
the certificate in tenths of a percent (unrounded) but must not
be shown on the official certificate.
c. Factor Only Inspections. Applicant may request the factor(s) for
inspections. The class of rice must be recorded on the grade line of the
official certificate. The type may be recorded on the grade line upon
request. A numerical grade will not be assigned on the grade line of the
certificate. Factors must be recorded on the work record and in the
“RESULTS” section on the official certificate.

certification by requesting it on the application for inspection.
The request must be filed prior to the beginning of the
inspection.
Note: If no request for either option is submitted prior to
the beginning of inspection, certification must be
“Option 1.”
(b) Under “Option 1,” rice offered for inspection is certified as a
specific grade. (e.g., “U.S. No. 2 Long Grain Rough Rice.”)
(c) Under “Option 2,” rice offered for inspection would be
certified as being a specific grade “or better.” (e.g., “U.S. No.

6.17 OTHERWISE GRADE INSPECTIONS
a. Applicants may request information as to what the quality of rice in a lot or
sample would “otherwise grade” if the results of one or more factors were
not considered.
b. When requested, official personnel must:
(1) Determine and show the actual grade of the lot or sample in the
space provided for the grade designation; determine requested
factors only and show the type or class of the rice on the grade line
(e.g., “Milled Rice”).
(2) Show the grade determining factor results and the results of other

Chapter 7: Round-Lot Inspection
Plan
August 2020
7-2
7.1 GENERAL INFORMATION
a. A roundlot is a single lot of bulk or bagged rice that is comprised of
multiple units. Roundlots are usually loaded aboard, or unloaded from,
two or more carriers. However, a lot of rice loaded aboard a single barge
or ship may also be considered a roundlot.
b. The roundlot inspection plan provides for sampling and inspecting
roundlots of rice.
(1) Rice inspected under this plan is examined for both uniformity in
quality and compliance with grade, factor, and/or contract
requirements. (Roundlots may be inspected for grade, grade and
special factors, or factors only.)
(2) This plan utilizes established tolerances (i.e., statistically
predetermined limits) for accepting those occasional portions of a
lot that, due to known sampling and grading variations, may grade
below the desired lot quality.
7.2 APPLICATION FOR INSPECTION
a. Prior to loading or unloading the lot, the applicant must submit an FGIS-
907, “Application for Inspection and Weighing Services”, or an appropriate
cooperator’s form.
(1) The application must declare: (1) all official services requested; (2)
the contract requirements (i.e., contract grade, factor limits, and/or
other specifications); (3) the approximate quantity of rice in the lot;
(4) the sublot size; (5) “Option 1” or “Option 2” certification; and (6)
any other necessary information.
(2) The application must be signed.

7.3 COMPONENTS AND SUBLOTS
Note: Sublots must be recorded on FGIS-911 or logged in the order that
they are graded.
a. Component. A component is a portion of a sublot (e.g., one compartment
of a hopper car).
(1) Generally, there should be no less than two components in every
sublot.
(2) All components in the lot must be uniform in size (i.e., the largest
sized component no more than 5 percent larger than the smallest
sized component).
(3) Component size must be established by the official inspection
personnel and may not be changed once loading or unloading has
begun.
b. Sublot. A sublot is a portion of the overall lot (e.g., one railcar in a unit
train).
(1) Except for the last sublot, all sublots in the lot should be reasonably
uniform in size (i.e., the largest sized sublot no more than 25
percent larger than the smallest sublot), excluding the last sublot.
(2) To determine the allowable variation in size, multiply the smallest
size sublot by 1.25, and the resulting figure is the maximum sublot
size.
For Example: Bulk Sublot
If the smallest size sublot is 4,000,000 pounds, then the maximum
sublot size would be 5,000,000 pounds.
(4,000,000 x 1.25 = 5,000,000)
For Example: Bagged Sublot
If the smallest size sublot is 1,500, bags then the maximum sublot
size would be 1,875 bags.
(1,500 x 1.25 = 1,875)
Rice Inspection Handbook
Chapter 7: Round-Lot Inspection
Plan
August 2020
7-4
(3) The last sublot should not amount to less than 5 percent of the
average size of the sublots in the lot; unless after the final sublot is
loaded aboard a vessel and the National Cargo Bureau (NCB)
surveyor, port surveyor, stevedoring personnel, ship’s captain, or
other persons responsible for the security of the vessel, indicates
that more grain must be loaded for vessel security.
(4) Sublot size must be established by the applicant for inspection and
may not be changed once loading or unloading has begun without
the approval of the field office manager or the cooperator manager
c. Components and sublots must comply with the size restrictions in Table
7.1 – Component and Sublot Size.

Note: When two packers are fed from one bin and are used for bagging rice for
two different boxcars simultaneously, four component samples representing
approximately 60,000 pounds each, when uniform, may be combined and graded
as one sublot sample representing the two carriers, provided that each
component sample is obtained proportionally from each packing line.

7.4 UNIFORMITY CRITERIA
a. During the loading or unloading of a lot, draw a sample from each
component according to the procedures in Chapter 2, Sampling.
(1) When bulk rice is sampled with a compartmented probe, consider
each probe as one component sample.
(2) When bagged rice is sampled, each component must be
approximately equal in size and should be taken from no less than
eight bags.
(a) If the rice is sampled in a boxcar, use an X probing pattern
across the face of a tier and randomly space the sampling
during the loading or unloading.
(b) When the rice is sampled online, randomly space the
sampling during the loading or unloading.
b. Visually examine each component sample for uniformity of quality.
12
(i.e.,
No factors appear to exceed the grade/contract requirements by more
than the grade limit or the established roundlot tolerance.) For more
information, see section 7.10, “Roundlot Tolerances.”
Note: Do not examine component samples for milling yield.
c. If the component sample appears to be uniform in quality, combine the
sample with other uniform component samples to form a sublot sample.
d. When the component sample appears to be not uniform in quality, analyze
the sample for the potential nonuniform factor(s).
(1) For factors that have roundlot tolerances, make only one
determination.
(a) If the results do not exceed the roundlot tolerance, consider
the component as being uniform in quality and combine the
component sample with other uniform component samples
to form a sublot sample. Do not record the component factor
results on the log or FGIS-911.
12
See Chapter 3, Rough Rice, Chapter 4, Brown Rice for Processing, and Chapter 5, Milled Rice, for
insect infestation.
Rice Inspection Handbook
Chapter 7: Round-Lot Inspection
Plan
August 2020
7-6
(b) When the results exceed the roundlot tolerance, declare the
rice represented by that component sample to be a material
portion and certify it as a separate lot or as a portion of a
multiple grade lot, as appropriate.
(2) For all other factors, make two determinations.
(a) If the results of either determination are within the
grade/contract requirement, consider the component as
being uniform in quality and combine the component sample
with other uniform component samples to form a sublot
sample. Do not record the component factor results on the
log or FGIS-911.
(b) If the results of both determinations exceed the
grade/contract requirement, declare the rice represented by
that component sample to be a material portion and certify it
as a separate lot or as a portion of a multiple grade lot, as
appropriate.
e. Analyze each sublot sample for all contract and grade determining factors
and record the results on the log or FGIS-911.
Note: For a factor’s average results to be shown on the roundlot
inspection certificate, all sublots must be analyzed for that factor and
the sublot results must be properly recorded on the log or FGIS-911.
(1) For factors that have roundlot tolerances, make only one
determination.
(a) If the results do not exceed the grade/contract requirement,
consider the sublot as being within contract.
(b) If the results exceed the roundlot tolerance, declare the rice
represented by that sublot sample to be a material portion,
certify it as a separate lot or as a portion of a multiple grade
lot, as appropriate, and line through the factor results on the
log or FGIS-911.
(c) If the results exceed the grade/contract requirement, but not
the roundlot tolerance, consider the sublot as “within
contract”; provided that, the run rule is not subsequently
violated (see section 7.5, “Run Rule”).
Note: If the applicant requests “average milling yield”,
do not apply roundlot tolerances to the results.
Rice Inspection Handbook
Chapter 7: Round-Lot Inspection
Plan
August 2020
7-7
(2) For all other factors, make one determination
(a) If the results do not exceed the grade/contract requirement,
consider the sublot as being “within contract.”
(b) If the results exceed the grade/contract requirement, make
another determination and average the results of the two
determinations.
1 If the average meets the grade/ contract requirement,
consider the sublot as being “within contract.”
2 If the average does not meet the grade/contract
requirement, declare the rice represented by that
sublot sample to be a material portion, certify it as a
separate lot or as a portion of a multiple grade lot, as
appropriate, and line through the factor results on the
log or FGIS-911.

7-8
7.5 RUN RULE
a. When a sublot exceeds the grade/contract requirement for a factor, but
not the roundlot tolerance, average that sublot’s factor results with the
factor results of the next four consecutive sublots from the same source.
13
(1) If the average results are equal to or better than the grade/contract
requirements for all factors, consider the first sublot to be “within
contract.”
(2) If the average results are not equal to or better than the
grade/contract requirements for all factors, consider all five sublots
as a material portion and certify them as a separate lot, unless
corrective action is taken.
Corrective action consists of the following:
(a) Withdrawing (unloading) one or more of the five sublots
included in the average;
(b) Separately certifying the withdrawn sublot(s); and
(c) After withdrawal, reapplying the run rule. When a sublot(s)
is withdrawn, the run rule must be reapplied as if the
withdrawn sublot(s) had never been offered for inspection.
Note: Do not apply the run rule if there are less than five
sublots in the entire lot or less than four sublots
remaining in the lot after a “run” has started.
13
A “source” may be: (a) Rice moving from the warehouse floor to one carrier; (b) One packer that is
used for bagging rice for one carrier; (c) Two packers fed from two different bins, but used for sacking rice
for one carrier; (d) Two packers fed from the same bin, but used for bagging rice for two different carriers
simultaneously; (e) Each belt delivering bulk rice to a carrier; or (f) Each spout receiving rice from different
belts or shipping bins. Consider all other systems as “multiple sources” and sample/grade the rice from
each packer as a “source.”

7-9
7.6 TIME LIMITATIONS
If reasonably continuous inspection service is not maintained, a roundlot
inspection certificate must be issued for that portion of the lot inspected prior to
the break in inspection service or after each additional break in inspection
service.
a. “Reasonably continuous inspection service” can include inactive periods of
no more than 88 consecutive hours (includes weekends and holidays).
b. To be considered “reasonably continuous service,” at least one sublot
must be loaded during any 88-hour period. The 88-hour limit may be
extended at the discretion of the field office manager.
7.7 REVIEW INSPECTIONS
When a sublot’s factor results exceed either the grade/contract requirements or
the roundlot tolerance, the applicant may request an appeal inspection on that
sublot; provided that, the applicant withdraws the sublot from the lot.
a. The roundlot tolerances cannot be applied to a single sublot.
b. If the appeal inspection determines that the sublot meets the
grade/contract requirements, the sublot cannot be re-entered in the
original lot unless the applicant requests an appeal inspection on all of the
other sublots in that lot.
7.8 MATHEMATICAL OR WEIGHTED AVERAGE
a. After completing the inspection of all sublots, calculate the factor
information to be shown on the certificate(s) by one of the following
methods:
(1) Mathematical Average Method. If the lot is composed of 10 or
more “reasonably uniform”
14
sublots or any number of “uniform”
15
sublots, mathematically average the sublot factor results (excluding
any sublot(s) to be certified as a separate lot).
(2) Weighted Average Method. For all other lots, average the sublot
factor results (excluding any sublot(s) to be certified as a separate
lot) in the following manner:
14
The term “reasonably uniform” means that the largest sized sublot is no more than 25 percent larger
than the size of the smallest sublot (excluding the last sublot) in the lot.
15
The term “uniform” means that the sublots are one standard size or are within 5 percent of the
standard.

Note: For subjective factors (e.g., milling degree), show
on the certificate the lowest quality determined for one
or more sublots.

7.9 CERTIFICATION
a. If the mathematical or weighted average of all factors in the lot are within
contract requirements, issue one certificate.
b. When the average of all factors is not within contract requirements, issue
separate certificates for each individual sublot. Two or more sublots
failing to meet the same contract requirement may be combined and
certified together as a separate lot. Sublots that fail to meet different
contract requirements must be certified as separate lots.
Note: If there are less than five sublots in the lot or less than four
sublots remaining in a lot after a “run” has started, and the average
of the overall lot is not within contract requirements, the applicant
may request one certificate for the entire lot with the grade of the lot
determined by the average sublot results.
c. If the applicant requests “average milling yield,” show the average sublot
milling yield results for the entire lot and include the following statement in
the “REMARKS” section of the certificate:
“Sublot milling yield results ranged from (show the lowest percent of
whole kernels and the highest percent of whole kernels) percent to
(show the lowest percent of total rice and the highest percent of
total rice) percent.”
(This statement may be modified, as necessary, to clearly indicate the
actual range of whole kernels and total rice results in the lot.)
d. Issue an inspection certificate for each roundlot inspection. Show the
following information on each certificate:
(1) The identification and sampling date for each carrier;
(2) The date on which the last official service was completed (i.e.,
“inspection date”);
(3) The average results for each of the factors determined during
inspection; and
(4) The lowest results for subjective quality factors (e.g., milling degree
and color) that were determined for one or more sublots.

f. Special Contract Limit. When the contract requires a factor limit that
differs from the grade limit set in the U.S. Standards for Rice, use the
tolerance established for the next higher quality grade.
For Example: A contract for U.S. No. 3 Long Grain Brown Rice for
Processing limits the percentage of damaged kernels
(DK) to a maximum of 1.5 percent. The grade limit for
a U.S. No. 1 for red rice and damaged kernels is 1.0
percent, with a tolerance of 0.7 percent. The grade
limit for a U.S. No. 2 is 2.0 percent, with a tolerance of
1.0 percent. Use the tolerance for a U.S. No. 1 for
red rice and damaged kernels (0.7 percent),
establishing the maximum DK for sublots graded
under this contract at 2.2 percent.

7.11 EXAMPLES OF RUN RULE APPLICATIONS AND CORRECTIVE ACTION
Example #1. The declared grade of the lot is U.S. No. 5 Long Grain Milled Rice,
maximum 20.0 percent total broken kernels (TBK). The sublot results for TBK
are:
Sublot No. 1
21.3 percent
Sublot No. 2
20.0 percent
Sublot No. 3

Sublot No. 4
19.9 percent
Sublot No. 5
19.6 percent
Sublot No. 6
18.5 percent
Sublot No. 7
9.0 percent
Explanation. Sublot 1 exceeds the contract requirement for TBK but not the
tolerance. Therefore, the TBK results for sublots 1 - 5 are averaged.
a. The average TBK result is 20.5 percent. Since this exceeds the contract
requirement, sublots 1 - 5 are declared a material portion.
b. To correct the material portion, the applicant elects to withdraw sublot 1.
c. After withdrawing sublot 1, the run rule is reapplied with sublot 6 replacing
sublot 1.
d. The new average (sublots 2 - 6) is less than 20.0 percent.
e. After withdrawing sublot 1, the roundlot continues as if there had been no
run, except that the next potential run begins with sublot 3 (21.9 percent).
When the next four consecutive sublots (sublots 4 - 7) are averaged with
sublot 3, the result is less than 20.0 percent, so the rice is considered to
be within contract requirements.
Note: In this example, either sublot 1 or sublot 3 can be withdrawn
from the roundlot in order to meet the contract requirement of 20.0
percent or less. When a sublot is withdrawn, the run rule is reapplied
as if the withdrawn lot had never been offered for roundlot
inspection.

Sublot No. 9
19.6 percent
Sublot No. 10
21.7 percent
Sublot No. 11
20.4 percent
Explanation. Sublot 1 exceeds the contract requirement for TBK but not the
tolerance. Therefore, the TBK results for sublot 1 are averaged with the TBK
results for sublots 2 - 5.
a. The average result is over 20.0 percent. Since this exceeds the contract
requirement, sublots 1 - 5 are declared a material portion.
b. To correct the material portion, the applicant elects to withdraw sublot 1
and sublot 2. Withdrawal of only one of the two sublots would not have
been sufficient to lower the average of the five sublot group to 20.0
percent or less.
c. After withdrawing sublots 1 and 2, the roundlot continues as if there had
been no run, except that the next potential run begins with sublot 3 (20.3
percent).
d. When the next four consecutive sublots (sublots 4 - 7) are averaged with
sublot 3, the result is less than 20.0 percent, so the rice is considered to
be within contract requirements.

Sublot No. 5
2
Average
2.6 = 3
Explanation. Sublot 1 exceeds the contract requirement for OBS and HT but not
the tolerance. Therefore, the results for sublots 1 - 5 are averaged and yield an
average result of 2.4, which rounds to 2.
a. Since this does not exceed the contract requirement, sublots 1 - 5 are not
considered to be a material portion.
b. Sublot 6 exceeds the contract requirement for OBS and HT but not the
tolerance. Therefore, the results for sublots 6 - 10 are averaged and yield
an average result of 2.6, which rounds to 3.
c. Since this exceeds the contract requirement, sublots 6 - 10 are considered
a material portion.
Note: To determine results for a run for factors determined by count,
add the factor results for five consecutive sublots beginning with a
sublot which does not meet the contract requirements. Determine
the average for these sublots then round to the nearest whole
number according to established rounding.

8.1 GENERAL INFORMATION
The identity-preserved (IP) inspection plan provides for the certification of
bagged rice lots and bulk rough rice barges at one location based on results
determined at another location.
The remainder of this chapter provides guidance on the responsibilities, lot
identification, origin services, and destination services for bagged rice lots and
bulk rough rice barges, respectively.
8.2 BAGGED RICE LOTS
Accordingly, a lot of bagged rice is specifically identified, sampled, inspected
(and, when requested, checkweighed), and certified at an origin location. Then,
after the lot has been shipped to another official service location (destination), its
identity and condition is verified.
If the identification and condition of the lot has not changed, a new certificate is
issued. This certificate shows the grade, class, factor results, and other
information that were determined at origin, along with the carrier identification
and similar information determined at destination.
a. Responsibilities.
(1) Applicant at Origin. The applicant must:
(a) Complete an application for service.
1 Show “IP Inspection” in the “REMARKS” section.
2 Show the destination of the lot in the “REMARKS”
section.
(b) File the application with official personnel at origin prior to or
at the time of the service.
(c) Provide for the proper identification of the lot and maintain
the lot so that its identity is preserved.
(d) Provide the original certificates and any other pertinent
documents to the applicant at destination.
Rice Inspection Handbook
Chapter 8: Identity-Preserved
Inspection Plan
August 2020
8-3
Note: For shipments where destination services may be
requested before the origin certificate can be delivered
to the applicant at destination, the applicant at origin
should surrender the original certificates to the official
personnel at origin and request that the pertinent
information and identification codes be transmitted to
the official personnel at destination.
(2) Official Personnel at Origin. Official personnel must:
(a) Ensure that the lot is properly identified, and the identity is
maintained.
(b) Sample and inspect the lot; perform all the requested
services in accordance with the applicable procedures.
(c) Issue an official certificate in accordance with the applicable
procedures.
(3) Applicant at Destination. The applicant must:
(a) Complete an application for service.
1 Show “IP Inspection” in the “REMARKS” section.
2 Show the method that was used at origin to identify
the lot and the applicable bag code number or carrier
seal number in the “REMARKS” section. (e.g., “Lot
identified by coding bags - bag code number H123.”)
(b) File the application, the original certificate for the origin
inspection, and any other pertinent documents, with official
personnel at the destination office prior to or at the time of
the requested service. Note on the application the amount
of rice to be shipped.
(c) For lots identified only by carrier seal numbers, ensure that
official personnel are present prior to breaking the seals and
unloading the carriers. If such a lot is to be stored in a
warehouse or similar facility at destination prior to final
shipment, apply a code, or arrange for official personnel to
apply a code, to the bags during the unloading operation.

(4) Official Personnel at Destination. Official personnel must:
(a) Review the origin certificate, application for service, and any
other pertinent documents.
(b) Verify the identification and the condition of the lot, and,
when necessary, apply or witness the application of a bag
code to the bags during the unloading operation.
(c) Perform all other requested services in accordance with the
applicable procedures.
(d) Issue an official certificate(s) in accordance with the
applicable procedures.
b. Lot Identification. The applicant at origin must provide specific identity to
the lot by either coding the bags in the lot or sealing the carriers into which
the lot is loaded.
(1) Coding Bags.
(a) When coding is used, the applicant at origin must apply or
arrange for official personnel to apply a special and unique
code number to no less than 25 percent of the bags in each
carrier or sublot.
(b) Each code number must consist of four or more
alphanumeric digits. The first digit will be the letter
identifying the field office from the list below. The remaining
digits will be assigned according to procedures adopted by
the field office manager or cooperator, in cooperation with
the shipper.
B – Beaumont
J – Jonesboro
N - New Madrid
C – Crowley
L - Lake Charles
S - Sacramento
G – Greenville
T - Stuttgart
H - League City
(c) The code number must be applied with either a hand roller
stamp, commercial coder, coded tags sewn in seams, or any
other FGIS-approved method.
Rice Inspection Handbook
Chapter 8: Identity-Preserved
Inspection Plan
August 2020
8-5
1 Official personnel must maintain full control of hand
roller stamps, and any other similar FGIS owned
labeling equipment.
2 Official personnel must maintain a log of officially
issued IP lot codes.
(d) Official personnel must record the code number on the work
record(s) and in the “REMARKS” section of the certificate.
Note: If coded bags are subsequently loaded aboard
carriers, official personnel must observe the bags being
loaded into the carriers, witness the carriers being
sealed, and issue an observation of loading certificate
with the carrier identification and seal numbers listed.
(2) Sealing Carriers. When sealing is used, official personnel must
observe the bags being loaded into the carriers, witness the
carriers being sealed, and record the carrier identification and seal
number(s) on the work record(s) and in the “REMARKS” section of
the certificate.
c. Origin Services.
(1) Sampling, Inspection, and Other Services. Official personnel must:
(a) Sample, inspect, and perform all other requested services on
the lot in accordance with the applicable procedures.
(b) If a component/sublot does not meet contract requirements,
direct its removal from the lot and certify it separately.
Ensure that all coded bags in such components/sublots have
their code numbers obliterated or are emptied.
(2) Certification.
(a) Official personnel must certify the lot in accordance with the
applicable procedures. Record the IP code in the
identification field and show in the “REMARKS” section as
follows:
“FGIS IDENTITY PRESERVED CODE NUMBER: (number).”
A separate code number must be used for each lot.
Rice Inspection Handbook
Chapter 8: Identity-Preserved
Inspection Plan
August 2020
8-6
(b) Divided-lot certificates must not be issued on Identity
Preserved lots at origin.
d. Destination Services.
(1) Identification and Condition Verification. Official personnel must:
(a) Check bag code numbers or carrier seal numbers to
determine if the lot is the same as that identified on the origin
certificate. If the identification of the lot cannot be verified,
the IP inspection must be canceled.
(b) For lots identified only by carrier seal numbers, observe the
breaking of the seals. If such a lot is to be stored in a
warehouse or similar facility prior to final shipment, apply or
witness the application of a bag code to the bags during the
unloading operation.
(c) Examine the outside of all visible bags in each pallet or
barge for animal filth, wetness, infestation, and large holes.
Rice in a barge or ship may be examined while still in the
barge, on the deck of a ship, or in the shiphold; provided
that, a significant number of bags are accessible for
examination.
1 If animal filth, wetness, or large holes are found on
the outside of the bags, direct the applicant to remove
the bags from the lot and subtract the number of bags
removed from the lot. If the bags are not removed,
cancel the IP inspection on that portion of the lot that
contains the affected bags.
2 If insect infestation is found only on the outside of the
bags, allow the applicant to fumigate the lot and
request a condition examination. If the subsequent
condition examination determines that the rice in the
bags is free of live or dead insects, the lot may still be
certified under the IP plan. If the bags are not
fumigated, or if there is still live or dead infestation,
cancel the IP inspection on that portion of the lot that
contains the affected bags.
Rice Inspection Handbook
Chapter 8: Identity-Preserved
Inspection Plan
August 2020
8-7
Note: Do not sample fumigated rice until after the
time period specified by the manufacturer for the
effective use of the fumigant, the rice has been
adequately aerated, and a gas-free certificate has
been issued by a licensed fumigator.
(d) Draw a sample from approximately 1 percent of the bags in
each component or carrier. Examine each sample
separately.
1 If the sample is out-of-condition, direct the applicant to
remove the affected bags from the lot and subtract
the number of bags removed from the lot. If the bags
are not removed, cancel the IP inspection on that
portion of the lot that contains the affected bags.
2 If the sample appears to be of a lower quality than the
contract requirement, analyze the sample. If the
sample exceeds the “New Sample” tolerance for any
factor (see “Uniformity Tolerance Tables,” located in
Appendix 3, cancel the IP inspection on that portion
of the lot that contains the affected bags.
Note: The applicant may request a warehouse-lot
inspection on any portion of a lot which is out-of-
condition or off-grade (exceeds the “new sample”
tolerance).
(e) Perform any other services requested, such as
checkcounting and observation of loading.
(f) Fully describe on the work record and certify any off-
grade/out-of-condition portion of a lot so that bags from that
portion will not be subsequently included with another lot
without being inspected.
Note: Issue condition examination certificates for (a)
bags that were removed from the lot; (b) bags that were
not removed from the lot which have animal filth,
wetness, or large holes on the outside of the bags, or
which contain rice that is infested, out-of-condition, or
of a lower quality than the contract requirement; and (c)
bags that required a second examination subsequent to
fumigation.

(2) Certification. Official personnel must:
(a) If the identification and condition of the lot is determined to
be the same as that shown on the origin certificate(s), mark
the certificate(s) issued at origin “VOID” and issue a new
(destination) certificate.
(b) On each destination certificate, show the grade designation,
class, kind, factor results, and other service-related
information (e.g., checkweighing) taken from the origin
certificate(s). Show all other information, such as
identification of carrier, place of issuance, date, quantity, and
location, as determined at destination. Do not show the IP
code on the destination certificate.
(c) When a lot inspected under the IP plan is loaded aboard two
or more carriers, issue a separate destination certificate for
each portion of the lot, by carrier; provided, it has not been
more than 30 days since the first destination certificate was
issued.
1 Do not issue destination certificates on any remaining
portion of a lot after the expiration of the 30-day
period.
2 Show on each destination certificate the amount the
applicant requests; provided, the amount does not
exceed the total amount covered by the origin
certificate.
3 Attach and file the superseded origin certificate(s)
with a copy of the first destination certificate issued.
4 Document destination certificate number(s) on the
work records.
(d) Allow applicants to switch from “Option 1” to “Option 2”
certification. When two or more certificates are combined,
the lowest quality grade will prevail on the destination
certificate.
(e) Allow lots inspected under the IP plan to be combined with
other lots of like grade and kind that were inspected under
the IP plan or under the Warehouse Lot Inspection Plan (see
Chapter 9, Warehouse Lot Inspection Plan).

1 Once certificates are combined, no further combining
may be performed.
2 Factor results and other information must be based
on the weighted average of the results shown on the
origin certificates.
3 Multiply the number of bags recorded on each origin
certificate by the factor results shown on each
certificate.
4 Divide the total product by the total quantity of bags.
5 Follow the same procedure for other percentages,
count factors, and checkweights. In cases where a
percentage or count factor does not appear on all
origin certificates, the weighted average must be
based on those certificates which show the factor.
For subjective factors, such as milling degree and
color, show the factor which represents the lowest
quality grade shown on the origin certificate(s).

8.3 BULK IDENTITY-PRESERVED INSPECTION PLAN (BIP) (ROUGH RICE
BARGES ONLY)
The bulk identity-preserved (BIP) inspection plan provides for the certification of
bulk rough rice lots loaded into barges at one location based on results
determined at another location.
Note: BIPs are not allowed for milled rice or brown rice. BIP is only
allowed for bulk rough rice barges.
a. Requirements for Participation.
(1) Identification. The lot(s) must be loaded into a barge(s) that is
clearly marked with a unique word or alpha numeric identifier.
Barges must be sealed to preserve the identity of the lot.
(2) Sampling Methods. Only approved diverter-type (D/T) mechanical
samplers, Pelican and Ellis cup sampling methods are approved for
this inspection plan. Probe sampling methods are not approved for
this inspection plan.
(3) Lot Requirements. Each barge must have an official single lot
inspection certificate.
(4) Identity-Preserved. Use either FGIS-approved seals, an FGIS-
approved tamper evident security tape, and/or other approved
device(s) to secure the identity of each barge.
(5) Time Limits. Transfer to the final export vessel must occur within
30 days of the origin inspection service.
(6) Method of Transfer/Discharge. A floating rig using a “clam shell” for
the method of discharge is the only transfer method approved.

August 2020
8-13
(c) Do not issue Bulk Identity Preserved divided-lot certificates
at origin.
d. Destination Services.
(1) Identification and Condition Verification. Official personnel must:
(a) Check the barge identification and sealing device(s), to
ensure that the lot is the same as that identified on the origin
certificate. If the identification of the lot cannot be verified,
the BIP inspection must be canceled.
(b) Observe the breaking of the sealing device(s).
Note: Sometimes during transit, seals do break. If the
seal(s) is broken, but the condition of the lot is
unchanged, continue with the BIP inspection plan.
(c) During the unloading/transfer process, draw a sample from
each barge using Table 8.1 – Component and Sublot Size,
shown below:
TABLE 8.1 – COMPONENT AND SUBLOT SIZE
Carriers
Maximum Component Size
Maximum Sublot Size
Standard Barges
300,000 pounds
1,000,000 pounds
(d) Examine each sample separately. Examine the rice for
animal filth, heating, off-odors (sour, musty, and
commercially objectionable), infestation, and quality.
1 If animal filth, heating, off-odors, or Distinctly Low
Quality rice is found, direct the applicant to remove
the affected rice from the lot. Subtract the weight of
the portion removed from the lot and certify that
portion separately. If the rice is not removed, cancel
the BIP inspection on that portion of the lot that
contains the affected rice and certify the lot as having
(estimated quantity) of inferior rice loaded on board.
Rice Inspection Handbook
Chapter 8: Identity-Preserved
Inspection Plan

2 If the sample appears to be of a lower quality than the
contract requirement, analyze the sample. If the
sample exceeds the “New Sample” tolerance for any
factor (see “Uniformity Tolerance Tables,” located in
Appendix 3, cancel the BIP inspection on that portion
of the lot that contains the affected rice. (Do not
examine samples for milling yield.)
3 If insect infestation is found, notify the applicant and
record the amount and types of insects found on the
work records. The applicant may choose to fumigate
the lot in accordance with the guidelines in the
Fumigation Handbook. If the rice is fumigated, the
certificate will be issued as if the infestation
designation had never been assigned. If the applicant
chooses not to fumigate the lot, cancel the BIP
inspection on that portion of the lot that contains the
affected rice.
(e) Perform any other services requested.
(2) Certification. Official personnel must:
(a) If the identification and condition of the lot is determined to
be the same as that shown on the origin certificate(s), mark
the certificate(s) issued at origin “VOID” and issue a new
(destination) certificate.
(b) Allow lots inspected under the BIP plan to be combined with
other lots of like grade and kind that were inspected under
the BIP plan or single-lot plan.
(c) Allow applicants to switch from “Option 1” to “Option 2”
certification. When two or more certificates are combined,
the lowest quality grade will prevail on the destination
certificate.
(d) Factor results and other information must be based on either
the mathematical or the weighted average, as applicable, of
the results shown on the origin certificate(s).
(e) For subjective factors that are not quantified, such as color,
show the factor that represents the lowest quality grade
shown on the origin certificate(s).
Rice Inspection Handbook
Chapter 8: Identity-Preserved
Inspection Plan
August 2020
8-15
(f) On the destination certificate, show the grade designation,
class, kind, factor results, and other service-related
information taken from the origin certificate(s). Show all
other information, such as identification of ship, place of
issuance, date, quantity, and location, as determined at
destination. Do not show the BIP statement on the
destination certificate.
(g) When a lot inspected under the BIP plan is loaded aboard
two or more ship, issue a separate destination certificate for
each portion of the lot, by ship, provided it has not been
more than 30 days since the first origin certificate was
issued.
1 Do not issue destination certificates on any remaining
portion of a lot after the expiration of the 30-day
period.
2 Attach and file the superseded origin certificate(s)
with a copy of the first destination certificate issued.
3 Document destination certificate number(s)on the
work records.
(h) When BIP rice loaded on board a ship is loaded with rice
that is not uniform in quality, certify as a separate lot. When
the rice is non-uniform, the certificate for each lot loaded on
board the ship will show the grade of the lot, as well as the
following, located in the “REMARKS” section:
1 A statement that the rice has been loaded on board
with other rice;
2 The grade, location, and approximate quantity of the
other rice; and
3 Any additional information required by the
Administrator.
For Example: “This rice was loaded aboard with
approximately 1,500,000 pounds
of US No. 6 LGRUF in holds
1,2,3 without separation.”

9.1 GENERAL INFORMATION
a. A warehouse-lot is a multiple-unit lot of bagged rice, including rice in
containers and “tote” bags, or bulk rice in bins, that is at rest in a
warehouse, mill, or similar structure (e.g., staging units to be loaded into a
vessel).
b. The warehouse-lot inspection plan provides for sampling and inspecting
warehouse-lots of rice as a single lot.
(1) Rice inspected under this plan is examined for both uniformity in
quality and compliance with grade/contract requirements.
(2) This plan utilizes established tolerances (i.e., statistically pre-
determined limits) for accepting those occasional portions of a lot
that, due to known sampling and grading variations, may grade
below the desired lot quality.
9.2 APPLICATION FOR INSPECTION

9.3 COMPONENTS, BLOCKS, AND SUBLOTS
a. Component. A component is a portion of a block (e.g., 2,000 bags in a
4,000-bag block).
(1) There must be no less than two components in every block.
(2) All components in the lot must be reasonably uniform in size (i.e.,
the largest sized component no more than 25 percent larger than
the smallest component).
(3) Component size must be established by the official inspection
personnel and may not be changed once the inspection has begun.
b. Block. A block is a portion of a sublot consisting of 4,000 to 8,000 bags of
rice, or approximately 400,000 to 800,000 pounds of bulk rice.
Component size and composition must be established by the official
inspection personnel and may not be changed once the inspection has
begun.
c. Sublot. A sublot is a portion of the overall lot consisting of one or more
blocks.
(1) Except for the last sublot, all sublots in the lot must be reasonably
uniform in size. (i.e., The largest-sized sublot must not be more
than 25 percent larger than the smallest sublot, excluding the last
sublot.)
(2) Sublot size must be established by the official inspection personnel
and may not be changed once the inspection has begun.
d. Use Table 9.1 – Components, Blocks, and Sublots, shown below, when
determining the quantity of rice to include in a component, and when
determining the number of components in a block, blocks in a sublot, and
sublots in a lot.

When a bulk probe is used, consider each probe as a component sample.
e. After determining the number of components, blocks, and sublots in the
lot, identify the rice that will comprise each of the blocks.
(1) Review the size and physical layout of the lot.
(2) Randomly select a storage area (section, bay, or doorway).
(3) Then, begin physically grouping the rice into blocks and the blocks
into sublots. (e.g., Ex-railcar lot UP 1234 is identified as
component 1, components 1, 2, 3, and 4 are grouped together as
block 1, and blocks 1 and 2 are combined to form sublot 1.)
f. For bagged rice, determine which blocks must be made fully accessible.
(i.e., a minimum of one side of each pallet in a block is completely
exposed so that a sample may be drawn from any sack facing that side.)
.
(1) For new applicants, all pallets in each block must be made fully
accessible for inspection until 15 consecutive blocks are inspected
without noting any non-uniformity.
Rice Inspection Handbook
Chapter 9: Warehouse Inspection
Plan
August 2020
9-5
(2) For all other applicants, approximately one-fifth of the blocks must
be made fully accessible; provided that, if any non-uniformity is
noted in a component, block, or sublot, then all pallets in each of
the next 15 consecutive blocks must be made fully accessible.
Note: When some bags are non-uniform because of water
damage, bird droppings, or similar conditions, and these bags
are removed from the lot, the applicant is not required to make
the next 15 blocks fully accessible.
(3) For each lot inspected, a minimum of one block must be made fully
accessible.
(4) Use a random number table that has been assigned to the specific
applicant to determine which blocks must be made fully accessible.
(a) Divide the number of blocks in the lot by 5 and select that
number of random numbers. Select one additional number if
there is a remainder after dividing (e.g., if there are 19 blocks
in lot, select 4 random numbers).
(b) When a number selected from the random number table is
greater than the number of blocks in the lot, select another
number.
(c) The number selected from the table represents the intervals
between blocks that must be made fully accessible.
For Example: A lot has 20 blocks. Four random
numbers are selected: 5, 8, 3, and 6.
By using these numbers to plot the
intervals between selected blocks, it is
determined that blocks 5, 13, and 16
must be made fully accessible.

9.4 UNIFORMITY CRITERIA
a. Draw a sample from each component according to the procedures in
Chapter 2, Sampling.
(1) When bulk rice is sampled with a compartmented probe, consider
each probe as one component sample.
(2) Each component must be approximately equal in size.
(a) If the component being sampled is part of a block that must
be made fully accessible, a minimum of one bag from each
pallet must be sampled.
(b) If the component being sampled is part of a block that is not
required to be made fully accessible, a minimum of one bag
from each pallet that is accessible must be sampled.
Note: The surface of top bags on the top pallets of
blocks selected must be examined for condition.
b. Visually examine each component sample for uniformity of quality. (i.e.,
No factors appear to exceed the grade/contract requirements by more
than the grade/contract limit or the established warehouse-lot tolerance.)
Note: Do not examine component samples for milling yield.
c. If the component sample appears to be uniform in quality, combine the
sample with other uniform component samples to form a block sample.
d. When the component sample appears to be not uniform in quality, analyze
the sample for the potentially nonuniform factor(s).
(1) Warehouse-Lot Tolerances. For factors that have warehouse-lot
tolerances, make only one determination.
(a) If the results do not exceed the warehouse-lot tolerance,
consider the component as being uniform in quality and
combine the component sample with other uniform
component samples to form a block sample. Do not record
the component factor results on the log or FGIS-911.
Rice Inspection Handbook
Chapter 9: Warehouse Inspection
Plan
August 2020
9-7
(b) When the results exceed the warehouse-lot tolerance,
declare the rice represented by that component sample to be
a material portion and certify it as a separate lot. When this
occurs, the next 15 consecutive blocks must be made fully
accessible.
(2) Other Factors. For all other factors, make two determinations.
(a) If the results of either determination are within the
grade/contract requirement, consider the component as
being uniform in quality and combine the component sample
with other uniform component samples to form a block
sample. Do not record the component factor results on the
log or FGIS-911.
(b) If the results of both determinations exceed the
grade/contract requirement, declare the rice represented by
that component sample to be a material portion and certify it
as a separate lot. Show the average results of the
determination on the certificate. When this occurs, the next
15 consecutive blocks must be made fully accessible.
e. Visually examine each block sample for uniformity of quality. (i.e., No
factors appear to exceed the grade/contract requirements by more than
the grade/contract limit or the established warehouse-lot tolerance.)
Note: Do not examine block samples for milling yield.
f. If the block sample appears to be uniform in quality, combine the sample
with other uniform block samples to form a sublot sample.
Note: Since the size of blocks may vary by as much as 4,000 bags,
combine block samples in proportion to their size. For example, if 40
percent of the bags in the sublot are from block 1, then 40 percent of
the sublot sample should be taken from the block 1 sample.
g. When the block sample appears to be not uniform in quality, analyze the
sample for the potentially nonuniform factor(s).
Rice Inspection Handbook
Chapter 9: Warehouse Inspection
Plan
August 2020
9-8
(1) Warehouse-Lot Tolerances. For factors that have warehouse-lot
tolerances, make only one determination.
(a) If the results do not exceed the warehouse-lot tolerance,
consider the block as being uniform in quality and combine
the block sample with other uniform block samples to form a
sublot sample. Do not record the block factor results on the
log or FGIS-911.
(b) When the results exceed the warehouse-lot tolerance,
declare the rice represented by that block sample to be a
material portion and certify it as a separate lot. When this
occurs, the next 15 consecutive blocks must be made fully
accessible.
(2) Other Factors. For all other factors, make two determinations.
(a) If the results of either determination are within the
grade/contract requirement, consider the block as being
uniform in quality and combine the block sample with other
uniform component samples to form a sublot sample. Do
not record the component factor results on the log or FGIS-
911.
(b) If the results of both determinations exceed the
grade/contract requirement, declare the rice represented by
that component sample to be a material portion and certify it
as a separate lot. Show the average results of the
determination on the certificate. When this occurs, the next
15 consecutive blocks must be made fully accessible.
h. Analyze each sublot sample for all contract and grade determining factors
and record the results on the log or FGIS-911.
Note: For a factor’s average results to be shown on the Rice
Inspection certificate for warehouse-lot inspection, all sublots must
be analyzed for that factor and the sublot results must be properly
recorded on the log or FGIS-911.
(1) Warehouse-Lot Tolerances. For factors that have warehouse-lot
tolerances, make only one determination.
(a) If the results do not exceed the warehouse-lot tolerances,
consider the sublot as being “within contract.”
Rice Inspection Handbook
Chapter 9: Warehouse Inspection
Plan
August 2020
9-9
(b) If the results exceed the warehouse-lot tolerance, declare
the rice represented by that sublot sample to be a material
portion, certify it as a separate lot, and line through the factor
results on the log or FGIS-911. When this occurs, the next
15 consecutive blocks must be made fully accessible.
Note: If the applicant requests “average milling yield,”
do not apply warehouse-lot tolerances to the results.
(2) Other Factors. For all other factors, make two determinations.
(a) If the results of either determination are within the
grade/contract requirement, consider the sublot as “within
contract.”
(b) If the results of both determinations exceed the
grade/contract requirement, declare the rice represented by
that component sample to be a material portion, certify it as
a separate lot, and line through the factor results on the log
or FGIS-911. Show the average results of the determination
on the certificate. When this occurs, the next 15 consecutive
blocks must be made fully accessible.

9.5 CORRECTING NON-UNIFORMITY
When non-uniformity of quality is noted within an identified lot, the action required
to correct the non-uniformity will vary. Inspection personnel must exercise good
reasoning and judgement when at warehouse locations. Questionable or
unusual situations must be discussed with supervisory personnel before taking
final action.
Note: Whenever non-uniform bags are found in a lot, inspectors must
observe and verify that the affected bags are removed from the lot and
conspicuously marked as rejected.
a. Component Sample – Non-Uniform.
(1) When a component sample is found to be non-uniform in quality,
other component samples taken from the block must be carefully
examined before requiring that all pallets in the next 15 consecutive
blocks be made fully accessible.
(a) If the non-uniformity is limited to only a small number of bags
in the component, the non-uniform bags must be removed
from the lot and separately certified.
(b) In such circumstances, it would not be necessary to require
the next 15 blocks to be made fully accessible. However, if
the non-uniformity is prevalent throughout one or more
components, accessibility of the next 15 blocks is required.
(2) When a component is found to be non-uniform because of
conditions such as water damage or bird droppings, the non-
uniform bags must be removed from the lot and separately certified.
In such circumstances, it would not be necessary to require the
next 15 blocks to be made fully accessible. However, the top bags
of the next 15 blocks must be carefully inspected to ensure that all
such damaged bags are found and removed.
b. Insect Infestation – Not Fully Accessible. When insect infestation is found
in a component sample of a block that is not fully accessible, the inspector
must record the incident and continue with the inspection.
(1) If, by sampling consecutive blocks (fully accessible or not), the
inspector continues to find infestation, there would be no need to
require that the next 15 blocks be made fully accessible.
Rice Inspection Handbook
Chapter 9: Warehouse Inspection
Plan
August 2020
9-11
(2) If the infestation is not prevalent in one or more components of a
block, the inspector may require one or more of the next 15 blocks
be made accessible to determine the extent of the infestation.
(3) If flying moths are found on or around the block, there would be no
need to require that the next 15 blocks be made fully accessible.
However, the other blocks should be carefully examined for such
infestation.
(4) Bagged rice stored in warehouses sometimes becomes infested
with larvae, moths, and weevils. Often the entire lot is not infested,
but only a portion of the lot. Applicants may request that official
inspection personnel inspect and segregate the infested rice from
the rice that would be acceptable for shipment. Accordingly, the
rice may be inspected on a pallet-by-pallet basis, but not on a bag -
by- bag basis.
The following example illustrates the procedure to be used:
Step 1 The applicant requests an inspection of 100,000 bags
of milled rice on pallets in a warehouse.
Step 2 The warehouse-lot inspection plan is followed, and
the rice submitted for inspection is divided into
appropriate blocks.
Step 3 The plan calls for 5 sublots, each sublot containing
20,000 bags.
Step 4 The plan permits the inspector to have 20 blocks for
the entire lot. Each block will consist of 5,000 bags.
Step 5 Each block will have 5 components of 1,000 bags
each. (100 components in the total lot.)
Step 6 The inspector finds a component sample representing
1,000 bags that is not uniform in quality because of
dead insects in the sample or on the bags.
Step 7 The 4,000 bags that were found uniform in quality are
considered as an accepted block, and the sample
representing the 4,000 bags will be composited with
the sublot sample.
Rice Inspection Handbook
Chapter 9: Warehouse Inspection
Plan
August 2020
9-12
Step 8 The 1,000 bags of U.S. Sample Grade rice will be
separately certified and the Food and Drug
Administration (FDA) will be contacted in accordance
with FGIS Directive 9060.2, “Implementation of the
FGIS-FDA Memorandum of Understanding.”
Step 9 Notify the applicant of the above action.
Step 10 The applicant requests FGIS to perform a pallet-by-
pallet inspection to separate the infested pallets from
the acceptable pallets.
Step 11 FGIS informs FDA of the applicant’s request, and, if
FDA has no objections, FGIS will perform a pallet-by-
pallet inspection.
Step 12 The applicant will make each pallet accessible to the
inspector for inspection.
Step 13 Each pallet will be treated as a single lot inspection
and will first be inspected for condition. The minimum
number of bags sampled will be in accordance with
the Chapter 2, Sampling. More bags may be sampled
at the discretion of the inspector, and an individual
bag may be sampled more than one time.
Suspected infested areas that can be viewed through
the translucent bag material may be sampled to
determine if these areas are insects, seeds, or foreign
material. Some pallets may be rejected without
sampling by a visual examination if webbing, insects,
or insect refuse is present on the outside of the bags
or is viewed through the bag material. Samples taken
must be sieved to determine if insects are present
(one insect per pallet will be sufficient to consider the
pallet U.S. Sample Grade).
Note: Samples taken from suspected areas may
contain more seeds and foreign material than
representative samples. Samples taken at this
time are to determine condition only and must be
discarded after sieving.
Step 14 If the pallets examined for condition are found not to
be acceptable, they may be included with other
pallets of the same condition.
Rice Inspection Handbook
Chapter 9: Warehouse Inspection
Plan
August 2020
9-13
Failing pallets may be certified as one lot. A portion
of the bags on all four sides of the rejected pallet are
to be marked with a felt tip marker, chalk, roller
stamp, or other suitable means of identification.
Step 15 Pallets found to be in an acceptable condition (no
infestation) are to be immediately sampled for quality.
Samples are to be taken in accordance with the
procedures in Chapter 2, Sampling. This sample will
be sieved for infestation. One insect per pallet will be
sufficient to consider the pallet U.S. Sample Grade,
as a number of pallets will be combined to constitute
a lot. If no infestation is found, this sample will be
composited with other samples of the same quality to
make a lot sample.
Step 16 Issue two separate certificates at the conclusion of
the inspection: One certificate representing the pallets
found acceptable, and another certificate representing
the pallets found unacceptable. Show the quality of
the rice and condition of the containers on each
certificate.
Step 17 Notify FDA of the location and amount of rice that
meets the defect action level.
Step 18 No further inspection may be performed until the rice
is released by FDA.

9.6 TIME LIMITATIONS
If reasonably continuous inspection service is not maintained, a warehouse-lot
inspection certificate must be issued for that portion of the lot inspected prior to
the break in inspection service or after each additional break in inspection
service.
a. “Reasonably continuous inspection service” can include inactive periods of
no more than 88 consecutive hours (includes weekends and holidays).
b. To be considered “reasonably continuous service,” at least one block must
be inspected during any 88-hour period.
9.7 REVIEW INSPECTIONS
When a sublot’s factor results exceed either the grade/contract requirements or
the warehouse-lot tolerance, the applicant may request an appeal inspection on
that sublot, provided that the applicant withdraws the sublot from the lot.
a. The warehouse-lot tolerances cannot be applied to a single sublot.
b. If the appeal inspection determines that the sublot meets grade/contract
requirements, the sublot cannot be re-entered in the original lot unless the
applicant requests an appeal inspection on all of the other sublots in that
lot.

9.8 MATHEMATICAL OR WEIGHTED AVERAGE
After completing the inspection of all sublots, calculate the factor information to
be shown on the certificate(s) by one of the following methods:
a. Mathematical Average Method. If the lot is composed of 10 or more
“reasonably uniform”
18
sublots or any number of “uniform”
19
sublots,
mathematically average the sublot factor results (excluding any sublot(s)
to be certified as a separate lot).
b. Weighted Average Method. For all other lots, average the sublot factor
results (excluding any sublot(s) to be certified as a separate lot) in the
following manner:
(1) Multiply each sublot factor result by the quantity of rice (bags or
pounds) in the sublot.
For Example: Weighted Average Calculation

(2) Total the products for each factor column. (In the above example,
the total is 1,522,000.)
(3) Divide each totaled product by the total quantity (e.g., 1,522,000);
77,500 = 19.64, or 19.6 percent total broken kernels.
Note: For subjective factors (e.g., milling degree), show on the
certificate the lowest quality determined for one or more
sublots.
18
The term “reasonably uniform” means that the largest sized sublot is no more than 25 percent larger
than the size of the smallest sublot (excluding the last sublots) in the lot.
19
The term “uniform” means that the components are one standard size or are within 5 percent of the
standard.

9.9 CERTIFICATION
a. If the mathematical or weighted average of all factors in the lot are within
contract requirements, issue one certificate.
b. When the average of all factors is not within contract requirements, issue
separate certificates for each individual sublot:
(1) Two or more sublots failing to meet the same contract requirement
may be combined and certified together as a separate lot.
(2) Sublots that fail to meet different contract requirements must be
certified as separate lots.
c. If the applicant requests “average milling yield,” show the average sublot
milling yield results for the entire lot and include one of the following
statements in the “REMARKS” section of the certificate:
(1) “Sublot milling yield results ranged from (Lowest Percent – Highest
Percent Whole Kernels) % to (Lowest Percent – Highest Percent
Total Rice) %.”
Example: Sublot milling yield results ranged from 68%-72%
to 74%-77%.
(2) “Sublot Milling yield results ranged from (Lowest Percent – Highest
Percent) % Whole kernels - (Lowest Percent – Highest Percent
Total Rice) %.”
Example: Sublot milling yield results ranged from 68%-72%
Whole Kernels to 74%-77% Total Rice.
d. Issue an inspection certificate for each warehouse-lot inspection. Show
the following information on each certificate:
(1) The identification and sampling date(s);
(2) The date that the last sublot was graded as the inspection date;
(3) The average results for each of the factors determined during
inspection; and
(4) The lowest results for subjective quality factors (e.g., milling degree
and color) that were determined for one or more sublots.

For Example: A contract for U.S. No. 3 Long Grain Brown Rice for
Processing limits the percentage of damaged kernels
(DK) to a maximum of 1.5 percent. The grade limit for
U.S. No. 1 Red rice and damaged kernels is 1.0
percent, with a tolerance of 0.7 percent. The grade
limit for U.S. No. 2 is 2.0 percent with a tolerance of
1.0 percent. Use the tolerance for U.S. No. 1 Red
rice and damaged kernels (0.7 percent), establishing
the maximum DK for sublots graded under this
contract at 2.2 percent.

10.1 INTRODUCTION
a. The USDA Agricultural Marketing Service (AMS) purchases a variety of
100% domestically produced and processed commodity food products by
periodically issuing a Master Solicitation for Commodity Procurements
(Master Solicitation) for distribution through Domestic and International
Food Distribution Programs. These purchases support American
agriculture by encouraging consumption of domestically produced foods.
The products purchased by USDA are delivered to schools, food banks
and households in communities across the country and are a vital
component of our nation’s and the world’s food safety net.
b. USDA Foods purchasing is a coordinated effort. AMS Commodity
Procurement Program (CPP) develops the product and purchase
specifications, manages the Web-Based Supply Chain Management
System (WBSCM), and conducts the procurements. The Food and
Nutrition Service (FNS) manages the food and nutrition assistance
programs, including the National School Lunch Program and The
Emergency Food Assistance Program, generating demand (orders) from
qualified recipients for various USDA Foods and coordinating with AMS on
the purchase planning and scheduling.
c. FGIS provides official inspections for rice purchased by USDA to ensure
conformance with contract requirements. As official personnel, you play
several important and critical roles in the success of these programs.
Adhering to the inspection guidance and instructions provided in this
appendix ensures that:
(1) Programs receive both the quality and quantity of rice that
American taxpayers committed to the lots being inspected;
(2) Rice was processed and packaged under sanitary conditions as
required by the Food and Drug Administration (FDA);
(3) Packaging is sound and meets the purchase specifications for type
and marketing; and
(4) Rice inspected is properly loaded into a carrier that is suitable to
maintain its quality.
d. Your work is crital to the integrity and image of rice provided by USDA to
our fellow citizens in the United States and those that the U.S.
Government assists around the globe.
e. This chapter provides you with the information, guidance and documents
you will need to perform these important duties.

10.2 CONTRACT SPECIFICATIONS
a. The Commodity Requirement Documents (CRD) provide the contract
specifications that suppliers or companies use when bidding to sell rice to
USDA. These documents also outline relevant information regarding
FGIS inspections and responsibilities.
b. The applicant is responsible for providing all applicable contract
documents and specifications to FGIS. The quality, weight, and
packaging of the rice must be verified by Rice Inspection Certificates
issued by FGIS. In addition to the quality requirements, as determined by
officially sampling and grading, the documents also specify all the required
inspections that must be performed by FGIS. These requirements include
checkweighing, condition of food container examinations, and may include
checkloading.
c. Additional inspections may be required. Refer to the Rice Products for
use in Domestic Programs and Milled Rice and Fortified Milled Rice for
use in International Food Assistance Programs to determine FGIS
inspection and certification requirements for Domestic and Export
contracts.
d. The Master Solicitation - for Domestic and International programs will also
provide contract clauses with information regarding the required plant
examinations that include Food Defense Survey and Sanitation
Inspections. These examinations must be up-to-date when performing
commodity procurement inspections.

10.5 GENERAL INSPECTION PROCEDURES
Receive the “Application for Inspection and Weighing Services” (FGIS-907) from
applicant. (Cooperators may use similar form(s)).
a. Review the request for service and determine the inspection and weighing
services to be performed on the specified lot(s). Domestic and Export
contracts may require different inspection services according to the
Commodity Description documents. Contracts may also have varying
inspection requests. Work with applicant to ensure all required inspection
services for the specific contract are requested. Additional inspection
services may also be requested by the applicant.
(1) Obtain the necessary forms for official documentation (e.g., FGIS-
992, Condition of Food Container worksheet(s) (COFC), for the
type of food container being inspected);
(2) Determine the appropriate sampling device and scale according to
the size of the containers to be inspected and weighed;
(3) Identify the lot(s) for inspection to verify the size of the lot and the
location; and
(4) Determine how the lot will be identified (e.g., unique lot codes
marked on packaging by applicant, USDA assigned lot number).
b. Perform inspection and weighing services. A general order of inspection
and weighing services is as follows:
Note: Containers randomly selected may be used for multiple
inspection services (e.g., sampling, checkweighing and COFC).
(1) Sample the lot according to official procedures provided in Chapter
2, Sampling, of this Handbook.
(2) Checkweigh the lot according to Chapter 4, Checkweighing, of the
FGIS Weighing Handbook.
c. Checkweighing. Checkweighing is performed to determine the estimated
weight of the lot to ensure it meets the weight requirements of the
contract. (Chapter 4, Checkweighing, of the FGIS Weighing Handbook
provides the official procedures to use for performing the checkweighing
service.)
Rice Inspection Handbook
Chapter 10: Commodity Procurement
Lot Inspections

(1) To Checkweigh a lot, use an FGIS approved scale with the
appropriate division size for the weight of the container (e.g., bag,
package, baler) to be weighed. (See Table 10.1 – Weight Range
and Allowable Division Size, shown below.)
(a) If packaged in secondary (outer) containers, the secondary
containers will be checkweighed to determine the estimated
weight of the lot. Determine the appropriate division based
on the marked/specified (target) weight of the secondary
container.
TABLE 10.1 – WEIGHT RANGE AND ALLOWABLE DIVISION SIZE
Gross Product Target Weight Range
Maximum Allowable Division Size
Pounds

(b) If the product target weight is outside the range of this chart,
refer to Table 1, “Division Size Selection,” located in Chapter
4, Checkweighing, of the FGIS Weighing Handbook.
(c) Daily Scale Checks.
1 Balance and check the scales:
a At the beginning of each work shift and at least
one other time during each work shift;
b Each time the scale is moved to a new
location; and
c When the scale is left unattended and/or the
results or the balance is questionable.
(d) Scale - Procedures.
1 Set the scale on a relatively smooth, firm surface.
Adjust the level of the scale until balanced. Zero the
scale. The indicator must be stable at zero.
Rice Inspection Handbook
Chapter 10: Commodity Procurement
Lot Inspections
August 2020
10-8
2 Place a test weight(s) that is approximately equal to
the weight of the rice to be weighed in the center of
the platform. If the scale indication for the test load
applied is within tolerance, the scale may be used. If
the indicator is flashing between two divisions,
consider it one-half of a division. (See Table 2a,
“Maintenance Tolerances for Marked Devices,”
located in Chapter 4, Checkweighing, of the FGIS
Weighing Handbook.)
3 Record the scale check in the “Remarks” section of
FGIS-992, as follows:
“(Scale ID) checked at 0 and (weight(s) used)
at (military time) - OK - (weigher’s initials).”
Example: “Scale #0152 checked at 0 and 50lbs
at 0715-ok-LR”
(2) Establish a tare weight: (If no empty containers are available, refer
to Table 4, “Special Tare Weights,” located in Chapter 4,
Checkweighing, of the FGIS Weighing Handbook to establish tare
weight.)
(a) Find Single-Container Unit Tares:
1 Determine the average tare weight by averaging the
weight of at least 10 empty containers selected at
random.
2 If the combined weight of 10 containers is less than
the minimum weight for tare determination (refer to
Table 3, “Tare Weight Requirements,” in Chapter 4,
Checkweighing, of the FGIS Weighing Handbook)
add empty containers to the scale until the total
weight is equal to or greater than the minimum weight
for tare determination.
3 Divide the total weight of the containers by the total
number of containers weighed to determine the
average tare weight of one empty container.
4 Record tare weights following the guidance provided
on FGIS-992.
Rice Inspection Handbook
Chapter 10: Commodity Procurement
Lot Inspections
August 2020
10-9
(b) Find Multiple-Container Unit Tares:
1 Determine the average tare weight by averaging the
weight of at least 10 empty primary (inner) containers
selected at random and by averaging the weight of at
least 10 empty secondary (outer) containers selected
at random.
2 If, for either the primary or secondary containers, the
combined weight of 10 containers is less than the
minimum weight for tare determination (refer to Table
3, “Tare Weight Requirements,” in Chapter 4,
Checkweighing, of the FGIS Weighing Handbook),
add empty containers to the scale until the total
weight is equal to or greater than the minimum weight
for tare determination.
3 Divide the total weight of the primary containers by
the total number of primary containers weighed to
determine the average tare weight of one empty
primary container.
4 Divide the total weight of the secondary containers by
the total number of secondary containers weighed to
determine the average tare weight of one empty
secondary container.
5 Multiply the average tare weight of one empty primary
container by the number of primary containers in one
secondary container. Add this total to the average
tare weight of one empty secondary container to
determine the average tare weight of one unit.
For Example: 24 - 2 Lb. Polyethylene Bags
Inside a Paper Baler
Weight of 10 paper balers = 3.28 lbs.
Average weight of balers = 0.33 lbs.
Weight of 24 polyethylene bags = 0.22 lbs.
Average tare weight of one unit = 0.55 lbs.
6 Record tare weights following the guidance provided
on FGIS-992.
Rice Inspection Handbook
Chapter 10: Commodity Procurement
Lot Inspections
August 2020
10-10
(3) Determine the sample size for checkweighing according to Table
10.2 – Sample Size, shown below. Checkweigh no less than the
minimum number of units required per lot.
TABLE 10.2 – SAMPLE SIZE
Number of Units in Sublot
or Lot
Minimum Number of Units
Check weighed
0 – 1 500
12
1 501 – 3 000

3 001 – over
36
Randomly select containers to be weighed. Do not set a pattern of
selecting containers. If selecting samples online when there is
more than one filling scale, you must always select 2 adjacent bags
to ensure you are collecting weights from both filling scales.
(a) Confirm the scale is free from any obstruction. Weigh each
container by placing it in the center of the scale platform.
(b) Record the exact weight for each container as shown on the
scale in the gross weight columns on FGIS-992.
(c) After all weights are recorded, calculate the total gross
weight of the containers and record the results in block 18 on
FGIS-992.
(d) Divide the total gross weight by the number of containers
weighed to determine the average gross weight per
container. Record the results in block 23 on FGIS-992.
(e) Subtract the average tare weight from the average gross
weight to establish an average net weight per container.
Record the results in block 25 on FGIS-992.
(f) Multiple the number of containers in the lot by the average
gross weight, tare weight and net weight per container to
determine the estimated weights of the lot. Record the
results in blocks 26, 27 and 28 of FGIS-992.
(4) CPP domestic and export rice contracts have varying net weight
requirements and must be certified according to the following
guidance:
Rice Inspection Handbook
Chapter 10: Commodity Procurement
Lot Inspections
August 2020
10-11
Note: Domestic Rice does not specify a specific net weight
requirement.
(a) Compare the average net weight of the containers obtained
by checkweighing with the marked net weight on the
container or as specified in the contract.
1 If the average net weight of the containers meets or
exceeds the marked or specified net weight, multiply
the number of containers in the lot by the
marked/specified net weight and place this quantity
on the work record and in the “Remarks” section of
the certificate, as follows:
“Estimated Total Weight (pounds) Net: (net weight of
the lot).”
For Example: Average weight after
checkweighing 24/2 pound baler
lot was 48.26 pounds.
(marked/specified weight) 48.00 x 875 balers
= 42,000 pounds
2 If the average net weight of the containers is less than
the marked or specified net weight, multiply the
number of containers in the lot by the average net
weight obtained by checkweighing and place this
quantity on the certificate. Certify the lot as not
complying with the contract and place the following
statement indicating that the lot does not meet
average net weight on the work record and in the
“Remarks” section of the certificate:
“Estimated Total Weight (pounds) Net: (net weight of
the lot).”
“This lot does not meet contract weight requirements.”
For Example: Average weight after
checkweighing 24/2 pound baler
lot was 47.89 pounds.
(actual weight) 47.89 x 875 balers
= 41,904 pounds.
Rice Inspection Handbook
Chapter 10: Commodity Procurement
Lot Inspections
August 2020
10-12
“Estimated Total Weight (pounds) Net: 41,904.”
“This lot does not meet contract weight
requirements.”
(b) When “average net weight” requirements are specified, the
average net weight of the lot must be 98 percent or more of
the marked or specified net weight.
Note: Export Rice contracts specify an “average net
weight” requirement.
Determine the average net weight of the containers obtained
by checkweighing.
1 If the average net weight of the containers meets or
exceeds the marked or specified net weight, multiply
the number of containers in the lot by the
marked/specified net weight and place this quantity
on the certificate.
“Estimated Total Weight (pounds) Net: (net weight of
lot).”
For Example: Average weight after
checkweighing 50 kilo bag lot
was 110.26 pounds.
(marked/specified weight) 110.23 x 2000 bags
= 220,460 pounds.
“Estimated Total Weight (pounds) Net: 220,460.”
2 If the average net weight of the containers is less than
the marked or specified net weight, but not less than
98 percent of the marked net weight, multiply the
number of containers in the lot by the average net
weight obtained by Checkweighing, and place the
quantity on the work record and in the “Remarks”
section of the certificate.
Certify the lot as complying with the contract and
place the following statement on the work record and
in the “Remarks” section of the certificate indicating
that the lot does not meet average net weight:
Rice Inspection Handbook
Chapter 10: Commodity Procurement
Lot Inspections
August 2020
10-13
“Estimated Total Weight (pounds) Net: (net weight of
lot).”
“This lot does not meet average net weight
requirements.”
For Example: Average weight after
checkweighing 50 kilo bag lot
was 109.41 pounds.
(actual weight) 109.41 x 2,000 bags
= 218,820 pounds.
“Estimated Total Weight (pounds) Net: 218,820.”
“This lot does not meet average net weight
requirements.”
3 If the average net weight of the containers is less than
98 percent of the marked or specified net weight,
multiply the number of containers in the lot by the
average net weight obtained by checkweighing and
place this quantity on the work record and in the
“Remarks” section of the certificate.
Also certify the lot as not complying with the contract
and place a statement in the “Remarks” section of the
work record and the certificate:
“Estimated Total Weight (pounds) Net: (net weight of
lot).”
“This lot does not comply with contract net weight
requirements. Average net weight per container is
(the net weight per container for the lot).”

10.6 CONDITION OF FOOD CONTAINER INSPECTIONS
It is important that the rice is packaged in a way that will maintain its integrity until
it reaches the final destination. It is equally important that the packaging be
labeled in accordance with the purchase specifications. To accomplish this,
purchase specifications require that you perform a Condition of Food Container
(COFC) Inspection in accordance with the U.S. Condition of Food Container
Standards. The Condition of Food Container Manual provides procedures and
information necessary for performing COFC inspections.
Depending on the type of packaging used, two separate condition of container
inspections may be necessary -- one for the primary containers and one for the
secondary containers.
Note: Samples selected for COFC inspections may be used for other
inspection services, such as official sampling and checkweighing.
a. Definitions.
(1) Primary Container (Inner). The immediate container in which the
product is packaged, and which serves to protect, preserve, and
maintain the condition of the product.
(2) Secondary Container (Outer). The container in which one or more
primary containers are packaged.
(3) Sample Size. The number of containers (sample units) to check for
condition.
(4) Sample. Any number of sample units which are to be used for
inspection.
b. Basis of Determination. Sample size is determined according to Tables
for Inspection Levels and Plans, located in Attachment 4 of this Chapter.
Sample size is the based on the (1) level of inspection (2) lot size and (3)
sampling plan.
(1) Level of Inspection. There are three established levels of
inspection: (1) Reduced, (2) Normal, and (3) Tightened. The
plant’s history of producing acceptable and unacceptable food
containers determines which of the three levels of inspection that
will be applied. The AD-749, Cumulative Original Inspections for
Condition of Container worksheet, is used to record the results of
sequential lots to determine the level of inspection required.
Rice Inspection Handbook
Chapter 10: Commodity Procurement
Lot Inspections
August 2020
10-16
Determine which of the three levels of inspection the facility at
which you are performing the inspection is currently operating
under according to the AD- 749. The procedures for determining
the level of inspection can be found on the reverse of the AD-749.
If there is not an established inspection history for the facility,
default to the normal level of inspection.
Determine if you are performing an Origin Inspection or Other than
Origin Inspection. If “Other than Origin” inspection, refer to the
Condition of Food Container Manual, “Other than Origin Inspection
AQL’s” section.
If the inspection is a reinspection of a previously rejected lot that
has been reworked/reconditioned, use tightened level of inspection.
(2) Lot Size. Determine the lot size and the type and size of
container(s). Select the appropriate COFC Worksheet(s) for the
type(s) of packaging contained in the lot.
(3) Sampling Plan. The U.S. Standards for Condition of Food
Containers offers two sampling plan options: single and double
sampling plans.
c. Double Sampling Plan. A sampling scheme which involves the use of two
independently drawn but related samples, a first sample and a second
sample which is added to the first to form a total sample size. A double
sampling plan consists of first and total sample sizes with associated
acceptance and rejection criteria. The first sample must be inspected first,
and if possible, a decision as to acceptance or rejection of the lot will be
made before a second sample is inspected. When the decision cannot be
made on the first sample, a second sample is inspected; the decision to
accept or reject is based on the total sample size.
Note: Use the double sampling plan for original inspections, unless
the applicant requests the single sampling plan.
(1) The manner in which samples (first and second) are selected
depends on how the rice is being loaded for shipment.
(2) If the rice is being packaged and loaded directly into a carrier,
select both the first and second samples at the same time. Set
aside the second sample until it is determined if it is needed.
Rice Inspection Handbook
Chapter 10: Commodity Procurement
Lot Inspections
August 2020
10-17
d. Single Sampling Plan. A sampling scheme where the decision to accept
or reject an inspection lot with respect to a specified requirement is made
after the inspection of the prescribed number of sample units. A single
sampling plan consists of a single sample size with associated acceptance
and rejection criteria.
e. Procedure – Double Sampling Plan. For an illustrative example of both a
secondary and primary container using a double sampling plan, refer to
Attachment 1 and Attachment 2 at the end of this Chapter.
(1) Select the appropriate COFC Worksheet(s) for the type(s) of
packaging contained in the lot. When primary containers are
packed inside a secondary container, two separate condition of
container inspections must be performed on separate worksheets --
one for the primary containers and one for the secondary
containers.
When it is more time efficient, Condition of Food Container
inspections for both the primary and secondary containers may be
done at the same time.
When rice is packaged in polypropylene bags or polyethylene bags
inside paper or plastic balers, use the AD-3066 Flexible Containers
examination worksheet for both the primary and secondary
containers (when applicable). If the polyethylene bags are packed
in fiberboard boxes, use the AD-3065 Rigid and Semi-Rigid
Containers examination for the COFC inspection of the fiberboard
boxes.
Populate the examination worksheet(s) with the lot information to
include the following:
Rice Inspection Handbook
Chapter 10: Commodity Procurement
Lot Inspections
August 2020
10-18
(a) Inspection level the facility is operating under as previously
determined.
(b) Refer to the appropriate table (Table I-A, Table II-A or Table
III-A located in Attachment 4 of this Chapter) for the double
sampling plan and the level of inspection the facility is
operating under (normal, reduced, or tightened) to determine
the following:
1 Sample Code (CAA, CA, CB, etc.); and
2 Sample Size /No. of Sample Units for both the first,
second and total samples for the double sampling
plan.
Note: If the lot contains secondary and primary
containers, determine the number of sample units
for the primary containers that must be inspected.
Divide the number of required primary containers
by the number of secondary containers to
determine how many primary containers should
be selected from each previously selected
secondary container. (A maximum of 6 primary
containers per secondary is required. If the
number exceeds 6, you must select additional
secondary containers.)
3 Acceptable Quality Levels (AQL) Accept and Reject
limits for Critical, Major, and Total defects for the first
sample and the Total Sample:
a Acceptable Quality Level (AQL). The
maximum number of defects per hundred units
(DHU) which is acceptable as a process
average. Lots, or portions of production,
having a quality level equal to a specified AQL
will be accepted approximately 95 percent of
the time when using the sampling plans
prescribed for the AQL.
b Acceptance Number (Ac). The number in a
sampling plan that indicates the maximum
number of defects permitted in a sample in
order to consider a lot as meeting a specific
requirement.
Rice Inspection Handbook
Chapter 10: Commodity Procurement
Lot Inspections
August 2020
10-19
c Rejection Number (Re). The number in a
sampling plan that indicates the minimum
number of defects in a sample that will cause a
lot to fail a specific requirement.
(2) Perform a preliminary inspection (scanning), prior to drawing the
sample, to identify any obvious defects present. While “scanning”
the lot:
(a) Confirm the number of secondary containers in the lot; and
(b) Determine if any segments or portions appear abnormal
(e.g., Wet balers or bags, leaking bags, critical
abnormalities). If such segments or portions are noted, the
lot should be rejected for condition of container.
If the lot is rejected prior to sampling, it cannot be
subsequently inspected until the lot has been
reconditioned/reworked. If no abnormal portions are
observed, samples may be drawn to determine condition.
(3) Randomly select sample units for inspection whereby each unit in
the lot has an equal chance of being chosen. Use any method that
facilitates an unpredictable selection.
Ordinarily, the second sample set is not drawn unless the lot could
not be accepted or rejected based on the results of examining the
first sample set. However, there may be circumstances in which it
would be desirable to draw both first and second samples on the
initial sampling of the lot (e.g., the lot is being loaded directly into a
carrier during inspection). In such instances, the examination of the
second sample set should be held, pending the outcome of the
examination of the first sample.
If using the random number method for sample selection, number
the pallets in the lot to be inspected. The random number charts
are located in Attachment 5 of this Chapter.
Begin randomly selecting the required number of sample units for
the inspection.
Rice Inspection Handbook
Chapter 10: Commodity Procurement
Lot Inspections
August 2020
10-20
Note: If a defective container is observed which falls outside
the predetermined sampling pattern, do not purposely select
the container simply because it is defective. It should be
drawn only if it falls within the predetermined pattern.
However, the inspector should recommend that obviously
defective units be removed from the lot and be replaced. This
recommendation should be made for any defective container
appearing in the sample, even though the lot is found to be
acceptable. There will also be instances in which defective
containers are localized. For example, the entire top layer of a
pallet may show water damage and contain wet containers, or
the front of a stack may show extensive forklift damage. In
these instances, identify the defective containers, the location
and estimated quantity to properly inform the applicant if
reconditioning is in order.
(4) Analyze the first sample set selected for all applicable defects as
listed on the appropriate COFC worksheet. Note each defect found
for each ‘type of defect’ in the first sample column.
(5) Once all container units in the first sample set have been analyzed
and all defects noted, calculate the total number of the Critical, the
Major, and the defects. Add the number of all defects to determine
the Total defects.
Compare the total number of Critical; the total number of Major and
the Total defects to the AQL accept/reject levels as stated on the
container examination worksheet for the lot.
(a) If all defect totals are equal to or less than the acceptable
level, mark the action taken based on first sample as “lot
accepted”.
(b) If the total number of defects for any defect level (Critical,
Major and/or Total) meet or exceed the ‘reject’ level, mark
the action taken based on first sample as “lot rejected”.
(6) If the total number of defects for any defect level (Critical, Major
and/or Total) exceed the acceptable level but is less than the reject
level for the first sample, you must move into the second sample of
the Double Sampling Plan and analyze the second sample.
Analyze the second sample set selected for all applicable defects
as listed on the appropriate COFC worksheet. Note each defect
found for each ‘type of defect’ in the second sample column.
Rice Inspection Handbook
Chapter 10: Commodity Procurement
Lot Inspections
August 2020
10-21
Once all container units in the second sample set have been
analyzed and all defects noted, calculate the total number of the
Critical, the Major, and the Minor Defects. Add the number of all
defects to determine the Total Defects for the second sample.
Then, add the Minor defects, Major defects; Critical defects and
Total defects results of each category for the first and second
samples to determine the Grand total of each defect category.
Compare the Grand totals to the AQL accept/reject limits for the
Critical; Major; and Total categories.
(a) If all defect category Grand totals are equal to or less than
the acceptable level, mark the action taken based on second
sample as “Lot Accepted”.
(b) If the Grand total number of defects for any defect level
(Critical, Major and/or Total) exceed the acceptable level,
mark the action taken based on second sample as “Lot
Rejected”.
Note: When the lot contains both primary and
secondary containers, the results of these COFC
inspections are independent of each other (i.e., the
primary containers may be accepted while the
secondary containers may be rejected).
f. Procedure – Single Sampling Plan. For an illustrative example of both a
primary and secondary container using a single sampling plan, refer to
Attachment 3 of this Chapter.
(1) Select the appropriate COFC Worksheet(s) for the type(s) of
packaging contained in the lot. When primary containers are
packed inside a secondary container, two separate condition of
container inspections must be performed on separate worksheets --
one for the primary containers and one for the secondary
containers.
When it is more time efficient, Condition of Food Container
inspections for both the primary and secondary containers may be
done at the same time.
Rice Inspection Handbook
Chapter 10: Commodity Procurement
Lot Inspections

10-22
When rice is packaged in polypropylene bags or polyethylene bags
inside paper or plastic balers, use the AD-3066 Flexible Containers
examination worksheet for both the primary and secondary
containers (when applicable). If the polyethylene bags are packed
in fiberboard boxes, use the AD-3065 Rigid and Semi-Rigid
Containers examination for the COFC inspection of the fiberboard
boxes.
Populate the examination worksheet(s) with the lot information to
include:
(a) Inspection level the facility is operating under as previously
determined.
(b) Refer to the appropriate table (Table I, Table II or Table III
located in Attachment 4 of this Chapter) for the single
sampling plan and the level of inspection the facility is
operating under (normal, reduced, or tightened) to determine
the:
1 Sample Code (CAA, CA, CB, etc.)
2 Sample Size /No. of Sample Units for the single
sampling plan from the Origin Inspection section
Note: If the lot contains secondary and primary
containers, determine the number of sample units
for the primary containers that must be inspected.
Divide the number of required primary containers
by the number of previously selected secondary
containers to determine how many primary
containers should be selected from each
secondary container. (No more than 6 primary
containers can be selected from a secondary
container. If the primary sample size requires
more than 6 per secondary container, additional
secondary containers must be selected.)
(c) Acceptable Quality Levels (AQL) Accept and Reject limits for
Critical, Major, and Total defects for the Single Sample:
Rice Inspection Handbook
Chapter 10: Commodity Procurement

1 Acceptable Quality Level (AQL). The maximum
number of defects per hundred units (DHU) which is
acceptable as a process average. Lots, or portions of
production, having a quality level equal to a specified
AQL will be accepted approximately 95 percent of the
time when using the sampling plans prescribed for the
AQL.
2 Acceptance Number (Ac). The number in a sampling
plan that indicates the maximum number of defects
permitted in a sample in order to consider a lot as
meeting a specific requirement.
3 Rejection Number (Re). The number in a sampling
plan that indicates the minimum number of defects in
a sample that will cause a lot to fail a specific
requirement.
(2) Perform a preliminary inspection (scanning), prior to drawing the
sample, to identify any obvious defects present. While “scanning”

(a) Confirm the number of secondary containers in the lot; and
(b) Determine if any segments or portions appear abnormal
(e.g., wet balers or bags, leaking bags, critical
abnormalities). If such segments or portions are noted, the
lot should be rejected for condition of container.
If the lot is rejected prior to sampling, it cannot be subsequently
inspected until the lot has been reconditioned/reworked. If no
abnormal portions are observed, samples may be drawn to
determine condition.
(3) Randomly select sample units for inspection whereby each unit in
the lot has an equal chance of being chosen. Use any method that
facilitates an unpredictable selection.
If using the random number method for sample selection, number
the pallets in the lot to be inspected. The random number charts
are located in Attachment 5 of this Chapter.
Begin randomly selecting the required number of sample units for
the inspection.

(4) Analyze the sample set selected for all applicable defects as listed
on the appropriate COFC worksheet. Note each defect found for
each ‘type of defect’ in the first sample column.
(5) Once all container units in the sample set have been analyzed and
all defects noted, calculate the total number of the Minor, Major and
Critical defects. Add the number of all defects to determine the
Total defects.
Compare the total number of Critical; the total number of Major and
the Total number of defects to the AQL accept/reject levels as
stated on the container examination worksheet for the lot.
(a) If all defect totals are equal to or less than the acceptable
level, mark the action taken based on first sample as “lot
accepted”.
(b) If the total number of defects for any defect level (Critical,
Major and/or Total) meet or exceed the ‘reject’ level, mark
the action taken based on first sample as “lot rejected”.
Note: When the lot contains both primary and
secondary containers, the results of these COFC
inspections are independent of each other (i.e., the
primary containers may be accepted while the
secondary containers may be rejected).
g. Review Inspections.
(1) COFC Appeal must be performed:
Rice Inspection Handbook
Chapter 10: Commodity Procurement
Lot Inspections
August 2020
10-25
(a) Prior to when the lot is reworked/reonditioned;
(b) By a person(s) other than the person who made the
inspection being appealed, unless there is only one
authorized person available at the time and place of the
requested appeal inspection; and
(c) On the next larger sample size in the table used in the
original inspection.
(2) COFC Reinspection at origin:
(a) May only be done after a lot that failed has been reworked or
reconditioned and defects have been removed from the lot.
(b) Use tightened level of inspection.
(c) Single sampling plan must be used.
Refer to the Condition of Food Container Manual (Inspection section, J.
Reinspections) for “Other than Origin” (destination) inspection guidance.
h. COFC Certification.
When the official paperwork shows the “lot accepted” for a Condition of
Food Container inspection, record on the work record and in the “Results”
section of the certificate. Type “Pass” in “Factor Result” section of the
certificate next to the factor Condition of Food Container”.
When the official paperwork shows the “lot rejected” for a Condition of
Food Container inspection, record on the work record and in the “Results”
section of the certificate. Type “Fail” in “Factor Result” section of the
certificate next to the factor Condition of Food Container”. In the
“Remarks” section of the certificate, state the reason(s) the lot failed. Use
the following statement:
“Lot fails the US Standards for Condition of Food Containers because:
(reason(s) for fail).”
For Example: “Lot fails the US Standards for Condition of Food

[EXAMPLE] SECONDARY CONTAINER USING THE DOUBLE SAMPLING PLAN
A lot contains 500 secondary containers, of which each contains 24 - 2 pound primary
containers of Long Grain Milled Rice. The facility is currently operating under a
“Normal” level of inspection using the Double Sampling Plan. Refer to the appropriate
Table 1-A (shown below) to determine the correct code for the size of the lot.
For this example, you will use Code CA for the secondary container selection since 500
secondary containers are included in the lot, which meets the requirement of 6,000 or
less containers.
For the first sample, you will select 36 secondary containers to examine for COFC. As
per the table The Acceptable Quality Levels (AQL) for Origin Inspections are as follows:
0.25 = Critical
1.5 = Major
6.5 = Total (Minor, Critical and Major Defects)
Note: Transfer the appropriate AQL criteria from the appropriate Table (see
above) to the proper COFC worksheet (see below).
According to the above table, the lot will be rejected (Re) if any Critical defects are
found, or if (4) or more major defects, or (7) or more total defects are found in the first
phase. The lot will be accepted (Ac) if no critical and no major and (2) or less Total
Defects are found.
Rice Inspection Handbook
Chapter 10: Commodity Procurement
Lot Inspections
August 2020
10-29
If no critical defects are found, but up to (3) major or (6) total defects are found, you will
need to proceed to the second sample of the double sampling plan. This requires you
to randomly select an additional 60 secondary containers from the lot and inspect them
for Critical, major and minor defects on the appropriate COFC Worksheet.
Use the same method as above to determine acceptance (Ac) or rejection (Re) for the
Total of the first and second sample.

In the above worksheet example of the Double Sampling Plan, the results of the first
sample set for secondary containers indicate 2 Minor Defects and 2 Major Defects.
According to the AQL limits above, the lot can neither be accepted nor rejected based
on the results of the first sample. Therefore, the second sample must be implemented
by selecting an additional 60 secondary containers for a total of 96 containers.
In the second sample, the worksheet indicates 1 Minor Defect and 1 Major Defect were
found. Add the first sample and second sample defects for a Grand Total. The Grand
Total for the lot is: 3 Minor Defects, 3 Major Defects, and 0 Critical Defects, equaling 6
Total Defects. After Comparing the Major, Critical, and Total results to the AQL criteria,
the lot is accepted based on the second sample.
Note: Samples selected for COFC inspections may be used for other inspection
services, such as official sampling and checkweighing.

ATTACHMENT 2:
[EXAMPLE] PRIMARY CONTAINER USING THE DOUBLE SAMPLING PLAN
When there are primary and secondary containers, COFC inspections can be done in
conjunction with one another. Once you have examined the selected secondary
container and recorded the results, that container can be opened to provide the primary
container(s) to then perform the examination on those containers. Use the appropriate
COFC worksheet, codes, sample sizes and AQL limits for the number of primary
containers in the lot.
In this example, the lot consists of 500 secondary containers, each containing 24
primary containers (500 x 24 = 12,000). Refer to Table 1-A (shown above and also
located in Attachment 4 of this Chapter) for the lot size (6,001 -12,000 units) to
determine: the code CB; the first sample size is 120, the second sample size is 60; and
the AQL limits for origin inspections.
Select 120 primary containers from the 36 secondary containers. Divide the number of
primary containers by the number of secondary containers to determine how many
primary containers to select from the secondary containers. In the example, there are
36 secondary containers and 120 primary containers in the first sample. 120/36=3.333.
You will need to select between 3-4 samples from each secondary container until you
have obtained the required number of primary samples.
Note: You must divide the number of samples as evenly as possible per
secondary container.
Once the required number of primary containers have been examined and all defects
recorded on the COFC Worksheet, compute the total Critical, the total Major and the
total Minor defects. Refer to the AQL limits on the worksheet to determine the action to
be taken based on the first sample. This lot could not be accepted based on the results
of the first sample, and therefore, the second sample (an additional 60 primary
containers) was examined. The total defects from the first and second samples (total of
180 primary containers) were calculated and the grand total defects compared to the
AQL limits; the lot was accepted based on the second sample.
Note: You may not select more than 6 primary containers from any secondary
container. If the second sample is required for the primary COFC, and the
quantity exceeds 6 per outer container, you must select primary containers from
additional secondary containers.

[EXAMPLE] SECONDARY AND PRIMARY CONTAINER USING THE SINGLE
SAMPLING PLAN
A lot contains 500 secondary containers, of which each contains 24 - 2 pound primary
containers of Long Grain Milled Rice (500 X 24= 12,000). The facility is currently
operating under a “Normal” level of inspection using the Single Sampling Plan. Refer to
the appropriate Table 1 (below) to determine the correct code for the size of the lot.
Note: You may not select more than 6 primary containers from any secondary
(outer) container. If the sample size requires more than 6, you must select
additional secondary containers to pull primary samples from.
For this example, use Code CB for the primary container selection since 12,000 primary
containers are included in the lot, which meets the requirement of 12,000 or less
containers.
For the Single Sampling Plan, you will select 168 primary containers to examine for
COFC. As per Table 1, The Acceptable Quality Levels (AQL) for Origin Inspections are
as follows:
0.25 = Critical
1.5 = Major
6.5 = Total (Minor, Critical and Major Defects)
Note: Transfer the appropriate AQL criteria to the proper COFC worksheet (see
below).
According to the above table, the lot will be rejected (Re) if 2 or more Critical Defects
are found, or if 6 or more major defects, or 17 or more Total Defects are found in the
sample. Otherwise, the lot will be accepted.

Change No. 5: August 20, 2020
The Rice Inspection Handbook was revised to incorporate policy and procedural
changes throughout the entire handbook, since its initial date of publication, as well as
re-formatting and editorial updates to maintain in compliance with FGIS Administrative
Directive 3010.2, “Policies, Procedures, and Guidance Issuance.”
For all substantive revisions, updated hyperlinks were embedded within the text to link
directly to both internal and external content wherever possible. Explicit reference was
made to the following FGIS Directives:
• FGIS Directive 9070.6, “Reporting Violations of the U.S. Grain Standards
Act and the Agricultural Marketing Act of 1946”

Policy”
• FGIS Directive 9180.41, “Sacked Grain”
• FGIS Directive 9020.1, “Exemptions and Waivers of Official Inspection
and Class X Weighing Requirements”
Additionally, acronyms and organizational details were updated to reflect accurate
administrative structure and associated program information (e.g., reference to the
Grain Inspection Packers and Stockyards Administration (GIPSA) was replaced by the
Federal Grain Inspection Service (FGIS)).
Change No. 4: June 19, 2014
Chapter 3, Rough Rice; Chapter 4, Brown Rice for Processing; and Chapter 5,
Milled Rice, were revised to update the definition of moisture, moisture portion,
delete the reference to “Motomco” moisture meter, and reference the procedures
for performing a moisture determination using the GAC2500- UGMA and Perten
AM 5200-A moisture meters in the Moisture Handbook.
Incorporated Visual Aid: Chalky Kernels (VRI R-8.0), and clarified the procedure
for chalky kernel determination.

1. PURPOSE
This appendix establishes the policies and procedures for requesting,
performing, certifying, and monitoring official commercial inspection services
(OCIS) of rice performed under the Agricultural Marketing Act of 1946, as
amended (AMA).
2. GENERAL INFORMATION
a. Official commercial inspection services, like other official services, provide
for the inspection of rice in a lot or submitted sample, by official personnel,
using approved and check tested equipment. Unlike other services,
applicants for this service may also request that sampling and inspection
procedures be modified, certain equipment be used, file samples not be
maintained, and certificates not be issued.
b. There are two types of official commercial inspection services: (1) official
commercial sample-lot inspection services and (2) official commercial
submitted sample inspection services.
(1) Official Commercial Sample-Lot. Official commercial sample-lot
inspection services consist of official personnel sampling identified
lots of rice, and analyzing the lots for grade, official factors, official
criteria, or any combination thereof, according to the Official U.S.
Standards for Rice, this appendix, other FGIS instructions, and the
OCIS Agreement.
(2) Official Commercial Submitted Sample. Official commercial
submitted sample inspection services consist of an applicant, or
their agent, submitting rice samples to an FGIS Field Office or
Cooperator to analyze for grade, official factors, official criteria, or
any combination thereof, according to the Official U.S. Standards
for Rice, this appendix, other FGIS instructions, and the OCIS
Agreement.
Note: As used in this Appendix, official personnel refers to
any authorized Department employee or person licensed by
FGIS to perform all or specified functions under the AMA.
c. Official commercial inspection services are not available for the inspection
of export rice, or for phytosanitary inspections.

Appendix 1 – Official Commercial
Inspection Services
August 2020
A1-3
3. INSPECTION PLAN (OCIS AGREEMENT)
a. The proposed inspection plan must be presented to the FGIS Field Office
or Cooperator in writing.
b. The inspection plan must describe:
(1) Location for the inspection(s);
(2) Type of inspection (lot or submitted) – may include one or more
lots;
(3) Type(s) of rice
(4) Procedures and methods for sampling, if applicable;
(5) Factor(s) and/or criteria to be anaylzed;
(6) Procedures and methods for determining factor/criteria results;
(7) If file sample(s) will be retained – if yes, retention time; and
(8) How the results will be reported (certificate, pan ticket,
spreadsheet).
For Example: RL Rice Company requests official commercial
sample-lot inspections on all trucklots of Rough
Rice delivered to Mill X from May 1, 2018, to
May 1, 2019. Each trucklot must be sampled
with the mill’s mechanical truck probe in four
randomly selected locations. Each trucklot
sample must be inspected for milling yield,
damaged by heat (stain), and heat damaged
kernels. Sample will be divided into 162-gram
work portion using a boerner divider. Work
portion will then be milled using a #2 McGill
Miller.

Appendix 1 – Official Commercial
Inspection Services

Inspector will then determine the following factors on the Total Rice after
milling:
(1) Kernels damaged by heat (stain) - determine count;
(2) Heat damaged kernels - determine count; and
(3) Milling yield - determine by assessing the number of whole kernels
captured in pan after handshaking the Total Rice twice using a #12
plate. (No hand adjustments to whole or broken kernels).
All determinations will be performed in an unofficial inspection
environment.
Note: Do not maintain file samples or issue certificates. Provide
results via spreadsheet at the end of each day. Notify Ricky Rice, RL
Rice Company manager, if heat or stain is present in any lot.
c. FGIS Field Office or Cooperator managers must review each new request
for official commercial inspection service and determine if the requested
modifications in sampling and/or inspection procedures are reasonable
and proper. Although FGIS Field Office and Cooperator are not restricted
by State law, managers should ensure that commercial equipment meets
minimum State and local specifications and tolerances.
(1) Both the FGIS field office and the cooperator manager (when
applicable) must approve the inspection plan, in writing, prior to
providing the requested official commercial inspection services.
(2) The inspection plan becomes the OCIS Agreement once it has
been approved and has been signed by the applicant, the Field
Office manager and the cooperator manager when applicable. The
OCIS Agreement is only valid for the Field Office/Cooperator and
the applicant/location(s) named in the approved agreement.
(3) All approved OCIS Agreements must be kept on file at the Field
Office and the cooperator’s office (when applicable).
(4) Copies of approved OCIS Agreements must be provided to QACD.
(5) Copies of approved OCIS Agreements must be provided to
interested parties upon request.

4. REQUESTS FOR SERVICE, WORK RECORDS, AND CERTIFICATES
a. Requests for Service According to OCIS Agreement. Any interested
person may request an original, retest, appeal, or Board appeal official
commercial inspection service, as applicable under the AMA.
(1) Requests must be filed, in writing, with the FGIS Field Office or
Cooperator that is responsible for providing the requested service.
(a) For original inspection, and retest requests, applicants for
service may use any form that provides all necessary
information.
(b) For Appeal and Board Appeal inspection requests,

5. SAMPLING AND INSPECTION
a. Sampling Requirements. (Applicable to official commercial sample-lot
inspections only.) Samples must be obtained:
(1) By official personnel
(2) Using an FGIS-approved sampling device, or an open-throat probe,
a truck tailgate sampler, or a mechanical truck probe (core or
gravity-fill type only); and
(3) According to the sampling procedures in Chapter 2, Sampling, of
this handbook, or as agreed to by the applicant for inspection and
the FGIS Field Office or Cooperator, provided that such procedures
are reasonable and proper.(e.g., An applicant may ask that only
two probe samples be drawn, at random, from each truck lot, but
the applicant may not direct that samples be taken from particular
areas in the lot.)
Note: The same type of equipment and procedures used for
obtaining the sample used for the original inspection must be
used for obtaining a sample for any subsequent reinspection,
retest, or appeal inspection.
b. Inspection Requirements. Rice must be inspected:
(1) By official personnel.
(2) Using FGIS-approved inspection equipment, or commercial
equipment. Commercial equipment includes devices that are
approved or allowed by local or state weights and measures
jurisdictions as “legal for trade.” Much of the FGIS official
equipment meets stricter tolerances or design requirements than
commercial equipment; however, commercial equipment may be
considered for official commercial inspection services.
(3) According to the inspection procedures in this Handbook or as
agreed to by the applicant for inspection and the official service
provider, provided that such procedures are reasonable and proper.
(e.g., An applicant may ask that the percent of damaged kernels be
determined only if, in the inspector’s judgment, the sample or lot
contains 1.5 percent or more of damaged kernels. Otherwise, the
inspector should indicate “less than 1.5 percent” on the work record
for percent of damaged kernels.)
Rice Inspection Handbook
Appendix 1 – Official Commercial
Inspection Services
August 2020
A1-9
Note: The same procedures used for performing the original
inspection shall be used for performing any subsequent
reinspection, appeal inspection, or Board appeal inspection.
c. “Other Criteria” Test Requirements. “Other criteria” tests (e.g., TOFFA,
enrichment and fortification testing) must be performed:
(1) By official personnel ;
(2) Using FGIS-approved equipment and calibrations; and
(3) According to the test procedures in the appropriate FGIS
handbooks or directives.
6. FEES
a. Fees assessed for official commercial inspection services must be
reasonable and nondiscriminatory.
(1) FGIS field offices must charge according to published fees.
(2) Cooperators must either charge the fees shown in their approved
fee schedule or charge a negotiated fee. If a negotiated fee is
charged, the Cooperator must:
(a) Use their approved fee schedule as a basis for the fee; and
(b) Include a statement in their approved fee schedule that
official commercial inspection service is available, upon
request, and fees for this service will be negotiated on a
case-by-case basis.
7. MONITORING
FGIS Field Office or Cooperator quality assurance specialists must monitor the
grading accuracy of official personnel who perform official commercial inspection
services, using any methods deemed appropriate (e.g., over-the-shoulder
supervision, referee samples, and separation monitoring).

1. SCOPE
This appendix is only applicable to “CBOT Specifications for Rough Rice,” as
requested by the applicant.
2. SPECIFICATIONS
CBOT contracts include quality specifications based on U.S. Rice Standards.
These quality specifications are unique, as they include additional factors and
factors determined on portion sizes that are different than FGIS established
procedures. These inspection specifications must be requested at the time of
inspection and include:
a. U.S. No. 2 or Better Long Grain Rough Rice with the same established
standards promulgated by the USDA.
b. No Heat-Damaged Kernels, as defined by Visual Aid: Heat Damage (VRI
R-2.0) are permitted in a 500-gram sample.
c. No “Stained” (Damaged by Heat) kernels, as defined by Visual Aid:
Damaged by Heat (Stain) (VRI R-2.1) are permitted in a 500 gram sample.
d. A maximum of 75 “lightly discolored kernels,” Lightly Stained (not
damaged), as defined by Visual Aid: Lightly Stained (VRI R-2.2) are
permitted in a 500 gram sample.
e. All Rough Rice shall be of a southern origin or such other origin as the
exchange may approve and have a milling yield not less than 48% - 65%.
Rice Inspection Handbook
Appendix 2 – Rough Rice
Inspections for Chicago Board of
Trade (CBOT)

3. PROCEDURE
a. Follow normal rough rice milling procedures and grade according to the
Rough Rice chapter of this handbook.
b. In addition to determining the required grade determining factors in the
representative 500-gram portion, also determine the number of Kernels
Damaged by Heat (Stain) and Lightly Stained Kernels.
For reference, see Visual Aid: Damaged by Heat (Stain) (VRI R-2.1) and
Visual Aid: Lightly Stained (VRI R-2.2).
c. Since these determinations are not according to FGIS procedures, they
must be recorded in the “REMARKS” section of the work record.
Example: DHT - 12/500g
LS – 47/500g
4. CERTIFICATION
CBOT specifications that require results not based on U.S. Rice standards and/or
FGIS procedures, (Kernels Damaged by Heat in 500 grams and Lightly Stained
kernels), must be shown in the “REMARKS” section of the certificate.
a. When the factors, Heat Damaged Kernels and Kernels Damaged by Heat
(Stain) are requested by count in 500 grams, show the following statement
in the “REMARKS” section of the certificate:
“This rice contains (count) Heat-Damaged Kernels and (count)
stained kernels in (amount) grams. Stained is defined as being
Kernels Damaged by Heat.”
b. When the factor Lightly Stained kernels is requested by count in 500
grams, the following statement will be shown in the “REMARKS” section of
the certificate
“This rice contains (count) Lightly Stained kernels in 500 grams.
Lightly Stained kernels are not considered as damaged kernels and
are not included in the damaged results.”

1. INTRODUCTION
Because of sampling, equipment, and interpretive variations, grades or other
contract specifications of subsequent supervision inspections may be different
than those of original inspections although the true quality and condition have not
changed. When there is no actual change, a change in grade or other contract
specifications may be due to the sampling, equipment, or interpretive variations.
Such variations are measurable and predictable. Therefore, it can be
determined statistically that the results of an original inspection are correct when
the results of a subsequent supervision inspection are within the expected range
of prescribed tolerances.
Tolerances have been determined and are to be used for supervision of factors.
Note: For supervision purposes when the same separations are reviewed,
the results should be the same.
