Grain Grading Reference Cards are an aid for use in commercial inspection. Each 3.5″ x 3.5″ card shows a visual reference with guidance for interpretation and were developed by USDA/GIPSA to aid grain inspectors. The work surface for the VRI-BOARD measures 8″ x 15.5″.
Shown to the left is the VRI-BOARD which holds the cards and also provides a work surface in the approved color and style used by FGIS for official use in the inspection of all grains, edible beans, peas, and lentils.
