Certificate of Analysis (CoA) Testing Services

Signed CoAs for all test types — accepted by retailers, Amazon, and regulatory agencies.

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.

What a CoA Includes

Every Qalitex CoA includes: product description and batch number, test methods (USP, AOAC, ISO), results with specification limits, accreditation number and lab credentials, scientist signature and date, and chain of custody documentation. Reports are delivered in PDF format suitable for Amazon Seller Central, retailer portals, and regulatory submissions.

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.

Our Turnaround Time

Standard CoA delivery is 48–72 hours from sample receipt. Rush options are available for time-sensitive listings or compliance deadlines. We serve clients across all 50 US states from our Irvine, California laboratory.
