Certificate of Analysis document from Qalitex Laboratories

A Certificate of Analysis (CoA) is an official laboratory document that reports test results for a specific product batch, including identity, potency, purity, and contaminant testing, signed by an accredited scientist and accepted by retailers, regulatory agencies, and Amazon.

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 signed CoAs are accepted by Amazon, major retailers, distributors, and regulatory agencies worldwide.
