You've got a COA, but the lab name isn't in any database, or there's no accreditation listed. That's a problem you need to fix before you order, not after.

Look for ISO/IEC 17025 accreditation. This isn't a nice-to-have; it's the international benchmark for testing labs. If the lab isn't accredited, regulators will likely reject your reports—and you'll be stuck with a shipment you can't sell.

You can verify accreditation by checking the lab's certificate number on the accrediting body's website. If you can't find it, ask the supplier for proof. If they can't provide it, that's a stop sign.
