Certificate of Analysis (COA)

A Certificate of Analysis, commonly abbreviated as COA, is a document issued by a regulatory or quality assurance entity that confirms a regulated product meets its product specification. They contain the actual results obtained from testing performed as part of quality control of an individual batch of a product. This document is crucial in ensuring the safety and quality of products, particularly in industries such as pharmaceuticals, biotechnology, and food manufacturing. A COA typically includes information such as the name of the substance or material tested, its batch number, the date of manufacture, the date of analysis, the reference against which the product was tested, and detailed results of tests performed. These tests could include assays to determine the product’s composition, identification tests to confirm the presence of the active ingredient, and tests for impurities or contaminants. The COA may also list the methods used to conduct these tests, ensuring that they comply with industry standards and regulatory guidelines. By providing a COA, manufacturers and suppliers offer transparency and build trust with customers, confirming that the product they are purchasing has been rigorously tested and meets the claimed specifications.
