Certificate of Analysis (COA)

A Certificate of Analysis (COA) is an official document provided by a manufacturer that details the results of tests conducted on a product, typically to verify its quality, identity, purity, and safety. It includes information such as the product’s specifications, test methods, and whether it meets specified standards. Think of it as a quality report that assures buyers or regulators that the product has been properly tested and is consistent with its claimed attributes. Overall, a COA provides transparency and confidence in the product’s integrity and compliance.
