How to Verify a Chinese Supplier: a Practical Checklist

A quotation and a video call rarely tell you how a supplier will perform once your purchase order is placed. Most sourcing problems — delays, specification drift, incomplete documents — can be predicted by checks you run before the first order. This checklist covers what we verify on the ground in China, in the order we verify it.

1. Confirm the legal identity

• Business licence. Ask for the company's licence and check the Unified Social Credit Code (18 characters) against the official National Enterprise Credit Information system. Confirm the registered name matches the name on the quotation and, later, on the contract and invoices.
• Registered scope and capital. The registered business scope should plausibly cover the product you are buying. Very low registered capital for a claimed large factory is a flag to investigate, not a verdict.
• Who are you actually dealing with? Many "factories" are trading companies. That is not necessarily bad — but you should know it, because it changes pricing, quality control and your recourse if something goes wrong.

2. Check manufacturing capability

• Product fit. Does the supplier really make this product family, or something adjacent? Ask for evidence of similar past production: photos with dates, packing lists, export references.
• Key equipment and processes. For your product, list the two or three processes that determine quality (welding, powder coating, injection moulding, final assembly and testing…). Verify the supplier owns those processes or identify which ones are subcontracted.
• Capacity and lead time. Compare the promised lead time to visible workload. A quote that undercuts every competitor with half the lead time is usually paid for later, in delays or quality.

3. Test the certificates, don't collect them

• Ask for test reports and certificates for the specific product, not the company brochure set. Check that the model references, standards, dates and issuing laboratories are consistent with what you are buying.
• Certificates can be borrowed, expired or edited. Cross-check report numbers with the issuing laboratory when the stakes justify it.
• Remember the boundary: no sourcing or inspection company can "guarantee CE compliance" for you. Responsibility stays with the manufacturer and the importer — what you can verify is whether the documentation is consistent, current and complete.

4. Use samples as evidence, not reassurance

• Request samples from the production line that would make your order, and keep an approved reference sample (signed, dated, photographed) before mass production.
• Document tolerances and acceptance criteria in writing at sample stage. "Same as sample" is only enforceable if the sample and its criteria are controlled documents.

5. Visit — or have someone visit for you

• A half-day site visit answers questions no document can: real production lines versus showroom, workforce level, housekeeping, quality stations, outgoing goods area.
• If you cannot travel, use a local representative who works for the buyer and reports facts with photos — not an intermediary paid by the factory.

6. Agree the working rules before the first order

• Written specifications, an approved sample, agreed inspection criteria and a clear escalation path cost little to set up and prevent most disputes.
• Confirm payment terms that keep leverage until quality is verified — for example, balance after a passed pre-shipment inspection.

What this looks like in practice

Panda United runs this verification as a defined, fixed-fee assignment from Shanghai: registration and identity checks, capability review, site visit where agreed, certificate plausibility checks and a written risk assessment with evidence. It is a risk assessment, not a financial or certification audit — and it is the single cheapest insurance you can buy before wiring a deposit to a new supplier.
