Canadian mustard seed and Canada Grain Regulations

Mustard seed is one of the grains defined in Canada Grain Regulations – Section 5. This means that the Canadian Grain Commission establishes and maintains quality standards for mustard seed. Also, this means that mustard seed is one of the crops protected by security. If a licensed grain company refuses or fails to pay for a delivery of mustard seed, the producer can make a claim against security.

Canadian mustard seed standards and grades

The Canadian Grain Commission defines Canadian grain standards and assesses the grade of grains against these standards. The Grain Grading Guide contains all the standards for Canadian grain. Chapter 12 presents the standards for mustard seed.

The Western Standards committee and Eastern Standards committee review these grading standards and recommend changes when necessary. The committees also select the standard samples of Canadian grain used each year.
