Grain grading

In Canada, grain grades are a tool used to define the quality of grain. Grades relate to a grain's end-use quality, meaning grades relate to how grain characteristics affect performance during processing (e.g. how much flour is produced during milling) or the quality of the end product (e.g. texture of cooked pasta). Under the Canada Grain Act, the Canadian Grain Commission is responsible for establishing and maintaining Canada’s grain grading system.

Most countries that grow, export or import grain use grain grades, and grades are part of transactions in the Canadian grain industry. In addition to grade, transactions can be based on contract specifications to meet the customer’s end-use requirements. Generally, producers are paid based on the grade of grain they deliver.
