Certificates of Analysis

Meaning

Certificates of Analysis, commonly referred to as CoAs, are formal, quality-control documents issued by manufacturers or third-party testing laboratories for a specific batch of a raw material, excipient, or finished product. This document attests that the tested batch meets its pre-established specifications for identity, purity, potency, and composition. The CoA serves as a critical assurance tool in regulated industries, including pharmaceuticals and dietary supplements, verifying that the product conforms to quality and safety standards before it enters the supply chain.
