From the opening
A commodity is graded by sampling a lot and scoring it against a published standard. The grade is a class, such as a number and a color or type, that summarizes measurable factors so a contract can name the class instead of the particular pile. The opening covers a sample stands for the lot, factors map onto a class, and the certificate carries the grade.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
