I have received a certification from one of our suppliers. They were audited by BRC on Issue 1 of Agent & Brokers and they fall under category number 3: Packaging Materials. Their certification grade states 'Pass' but I am unaware due to lack of knowledge on this standard on how they get graded. I previously believed that all standards use the same grading of AA, A, B .. etc. Can somebody please confirm how they are graded.
