Certificate Checks
How do you verify whether a Chinese supplier's certificates are real?
Do not ask only whether a certificate is real. Ask whether it belongs to this company, covers this site, applies to this product, and is still valid for the market you plan to sell into.
Suppliers often send a folder of certificates as proof that everything is in order. Some documents may be genuine and still provide little protection for your order. A system certificate can cover a different factory. A test report can cover an old sample. A compliance document can apply to a product that is similar but not identical to yours.
Match the legal entity and production site
Check the company name, address, certificate number, issue date, expiry date, and scope. If the certificate belongs to an affiliated company or another plant, ask why that entity is relevant to your order. The name on the certificate should not be treated as interchangeable with every company in a sales group.
Read the scope, not only the logo
Certificates are issued for specific systems, activities, products, or test samples. Read what the document actually covers. A general quality-management certificate does not prove that your product meets a destination-market requirement. A report on one model does not automatically cover a modified version, different material, or different manufacturer.
Verify the issuer and document trail
Look for the issuing body, report or certificate number, test method, sample description, and a way to verify the document with the issuer where available. Do not rely on a cropped screenshot. When compliance is commercially important, obtain the full report and confirm that the tested sample can be connected to the batch or product you intend to buy.
Use certificates as one layer of evidence
Documents should sit alongside company verification, product specifications, sample review, and production controls. They are not a substitute for knowing who is responsible for the goods and whether the factory can produce them consistently.
The useful outcome is not a larger certificate folder. It is a short, clear file showing which documents apply to your exact supplier, product, batch, and destination requirement, and which questions still need an answer before payment.
