How it works

01

Upload your COA

Send the certificate as issued — PDF or link to the issuing laboratory's page.

02

We review it

An analyst checks the report ID at source, the batch reference, the dates and the attached trace.

03

Cross-check verdict

Passing certificates are marked cross-checked. Failing ones are rejected with the reason.

04

Published

Passing certificates appear on the public index, with the issuing laboratory named.

What review is not. We do not re-test the sample. We verify that the document is what it claims to be, that the identifier resolves at the issuing laboratory, and that the batch reference and dates are coherent. A cross-checked mark is not a pass and not an endorsement.
