Procedures October 2020 United States Department of Agriculture Agricultural Marketing Service Federal Grain Inspection Service Program Handbook October 2020 Grain Inspection Handbook – Book II Grain Grading Procedures Foreword The effectiveness of the official U.S. grain inspection system depends largely on an inspector’s ability to sample, inspect, grade, and certify the various grains for which standards have been established under the United States Grain Standards Act (USGSA), as amended. In view of this fact, the Federal Grain Inspection Service (FGIS) published the Grain Inspection Handbook. Book II, Grain Grading Procedures, sets forth the policies and procedures for grading grain in accordance with the Official United States Standards for Grain. The information contained in this handbook is applicable to official grain inspection services performed by FGIS, delegated State agencies, and designed State and private agencies. Persons interested in obtaining official services may contact any FGIS field office or official agency. Trade names are used solely to provide specific information.

The extra unworked portion cut from the representative sample that may be used in conjunction with the work sample when needed. Samples retained for grade should be approximately 1,400 grams or more, except for the lighter grains (e.g., oats or barley) that require less grain to determine grade. For factor only tests or official criteria (e.g., wheat protein or falling number), smaller file samples should prove sufficient to handle review services. File samples larger than 1,400 grams may be retained if deemed necessary to provide subsequent inspection service. Kind of Grain. A determination as to whether a sample meets the definition of a specific grain or oilseed as established in the Official U.S. Standards for Grain. Official Agencies (OA). State and private partners authorized by FGIS to provide official inspection and weighing services to the domestic and export grain trade on FGIS behalf. Official Personnel. Any authorized Department employee or person licensed by FGIS to perform all or specified functions under the Act. Official Service Providers (OSP). Federal offices and State and private agencies authorized by FGIS to provide official inspection and weighing services to the domestic and export grain trade. Representative Portion. A specified quantity of grain divided out from the representative sample by means of an FGIS-approved device. Representative Sample. The terms “Representative Sample” and “Original Sample” are used interchangeably in the Grain Inspection Handbook. Both terms refer to a sample size of approximately 2,500- 3,000 grams in size drawn from a lot by official inspection personnel using approved procedures and sampling devices. For more information on sampling, refer to Book I, “Sampling Procedures.” Review Inspection. All follow-up grade inspections available (reinspection, appeal, or board appeal). Work Sample. A representative portion of grain; approximately 1,000 - 1,050 grams, used to make determinations required for a particular grain.
