A Certificate of Conformance (CoC) is a formal document that certifies a product or service meets specific quality, performance, or safety standards. It is often issued by manufacturers or independent laboratories and is essential for ensuring compliance with regulatory requirements in various industries. CoCs facilitate international trade by providing assurance that products adhere to necessary specifications, thereby reducing the risk of defective goods and potential litigation. This document typically includes details about the product, the standards it complies with, and the issuing authority.
