Header & ID
Document title, issuing laboratory, COA number, and production batch or lot identifier for unambiguous traceability and record linkage.
A complete COA reduces shipment rejections, enables consistent release decisions, and documents compliance with quality and regulatory requirements. It provides auditable evidence of testing, links to batch records, and a clear signature trail to assign responsibility.
Multiple stakeholders rely on the COA for traceability, dispute resolution, and to meet customer or regulatory obligations.
The Lab Director or designated laboratory manager certifies test methods and results. Their signature confirms that accredited procedures were used and that the data reported are complete and accurate.
The Quality Manager or authorized quality representative reviews the analytical data and chain-of-custody, approves release, and accepts responsibility for product disposition and compliance with specifications.
