Official inspections result in the issuance of official certificates. Certificates report the grade of the grain inspected based on characteristics such as test weight, moisture, cleanliness, and damage. Certificates are issued for the various grains for which standards exist under the U.S. Grain Standards Act, as amended, and for rice, pulses, and miscellaneous processed commodities covered by Part 68 of the regulations under the Agricultural Marketing Act of 1946, as amended.

Certificates are the final product in the chain of official inspection services. They document the official procedures followed; date, location of the inspection or weighing process, and provide specific service results factor-by-factor or by service requested.

GIPSA continues to modernize its grain inspection and weighing business information systems to better meet the needs of its customers. In 2007, GIPSA will deploy a new certificate program. The new certification program will issue redesigned inspection and weighing certificates that are standardized in design, color, and size to make them more identifiable as official documents and easier to print.
