COA Verification

Certificate verification.

Enter the lot number printed on your label to retrieve the Certificate of Analysis issued for that lot.

What a certificate shows

The material's identity, the analytical laboratory, the dates of testing, the methods used and the documented results — exactly as the laboratory reported them.

One certificate, one lot

Certificates are bound to a single lot number in our records and cannot be attached to another lot. If the lot on your label differs from the certificate, do not rely on it.

Document integrity

Each original certificate is stored with its SHA-256 fingerprint, displayed beneath the record, so a downloaded file can be checked against what we hold.

If your lot is not found

Check the number against your label. If it still does not match, contact us and we will look into it. A missing certificate is treated as a documentation exception.

Integrating programmatically? Certificates for released lots are available as JSON at /api/coa/<lot>. See our standards.
