ISS launches public Certificate of Analysis verification

A Certificate of Analysis is only useful if the person reading it can trust that it's genuine and current. Until now, confirming that meant reaching out to the lab directly. That's changing: anyone holding an ISS certificate can now check it themselves, through a verification page on this site.

The process is simple. Enter the certificate reference printed on the document and the page returns its current status — valid, superseded by a later result, or revoked — along with the basic details of what was tested. No account or client relationship is required to check a certificate; verification is built for anyone downstream of the original client who needs to confirm what they're holding is real.

The three statuses map to how certificates actually move through their life after issue. Most stay valid indefinitely. A certificate is marked superseded when a later result replaces it for the same sample, and revoked if it's withdrawn for any reason. Making that state checkable, rather than something only the lab could confirm, is the point of the feature.

This is the first piece of a broader effort to make lab records more accessible to the people who rely on them, not just the client who commissioned the testing. It sits alongside the chain-of-custody work already under way, and both draw on the same underlying idea: documentation is more useful when it doesn't depend on trusting a claim at face value.

The verification tool is rolling out now. Existing clients don't need to do anything differently — certificates already reference the details needed to check them.
