Amazon Tightens COA Requirements for Supplement and Cosmetic Sellers
Amazon sellers face increased scrutiny as the platform mandates ISO 17025 accredited COA documentation for health and beauty products — with non-compliant listings facing immediate suspension.
Achieving quality control requires accurate, accredited laboratory testing that regulatory bodies and marketplace platforms trust. Qalitex Laboratories provides certificate of analysis tailored for quality control requirements. A Certificate of Analysis (CoA) is your product's credential for market access. Qalitex Laboratories provides ISO 17025 accredited CoAs for all test types — identity, potency, heavy metals, microbiology, pesticide residues, and stability. Our ISO 17025 accredited methods and detailed COA reports are designed to streamline your quality control process.
How Certificate of Analysis Supports Quality control
Quality control requires documented evidence of product safety and quality. Qalitex provides the specific testing and documentation needed to support your quality control process, including detailed COA reports, method validation documentation, and expert consultation on testing scope. Our ISO 17025 accreditation ensures your results are accepted by regulatory bodies and marketplace platforms.
