Certificate of Analysis (CoA) Testing Services
Signed CoAs for all test types — accepted by retailers, Amazon, and regulatory agencies.
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.
What a CoA Includes

When You Need a CoA
You need a CoA for Amazon FBA supplement listings, retail compliance (Whole Foods, Target, Vitamin Shoppe), import/export documentation, FDA facility inspections, brand protection and labeling accuracy, and third-party quality audits.
