Grading factors

Grades are assigned based on a sample’s ability to meet tolerances for various grading factors. A grading factor is a physical condition or feature that is evaluated to determine the quality of the grain. This condition can be a result of growing conditions, handling procedures or storage practices.

All grain grade standards and tolerances are listed by crop in the Official Grade Grading Guide.
