What a certificate actually says
This is the artifact. Read it before you decide whether it is worth anything to you. Note what it does not say.

Read what it does not claim
It does not say the item is safe. It says a screening happened, names the databases it ran against, timestamps them, and binds the whole record to a photograph of the label — cryptographically, so that altering any part of it breaks the signature.
That is a smaller claim than “this crib is safe”, and it is the only one we can actually stand behind. Anyone selling you the larger claim is selling you something they cannot deliver.
