How to Verify a Supplier in China Before You Pay: A Practical Checklist

Most problems buyers have with Chinese suppliers are predictable — and they start before the first payment, not after it. A supplier that was never properly checked cannot be fixed by a well-written contract later. This guide walks through the checks that matter, in the order a professional buyer would run them, using channels that are free or low cost.

1. Check the business license on the official registry

Every legally operating company in China has an 18-digit Unified Social Credit Code printed on its business license. You can verify it yourself, for free, on the National Enterprise Credit Information Publicity System (gsxt.gov.cn, Chinese language interface) — the official government registry. Look at four things:

• Status — the company must be "存续" (active). Avoid any record showing revoked, cancelled, or listed as abnormal-operation.
• Registration date — a company registered three months ago presenting itself as a ten-year manufacturer is a warning sign, not a deal-breaker by itself, but it changes how much you should risk on the first order.
• Business scope — it should cover manufacturing or trading of what they are selling you.
• Registered capital — treat this with caution: registration is on a subscription basis in China, so the number shows what shareholders committed, not what was actually paid in. It is not proof of financial strength.

Also check the China Customs Enterprise Credit Information Publicity Platform (credit.customs.gov.cn) to see whether the company is a registered importer/exporter and whether it has any customs violations on record. A factory with no export registration is not necessarily a fraud — many sell through trading companies — but you should know which situation you are in.

2. Decide whether the identity matches reality

A common misunderstanding: buyers believe they must find a "real factory" and that any trading company is a middleman to be cut out. In practice, both can work well. Factories are strong in their own product; trading companies are often better at mixed-container consolidation, communication and export paperwork.

What actually matters is whether the claimed identity matches the verified identity. A trading company posing as a factory is the real problem — it usually means the markup is hidden and quality control is one step further away than you think. Video calls that walk through the production floor, a request for a real-time tour rather than a recorded video, and a factory address you can cross-check on a map are simple ways to test this.

3. Audit the factory — in person, by a third party, or by video

If the order value justifies it, an on-site audit is the most reliable check. International inspection firms such as SGS, Bureau Veritas, TÜV, Intertek and QIMA offer supplier audits in China; they verify that the premises, equipment, workforce and certifications match what the supplier claims. Costs vary by scope and location, so ask for a quotation directly.

For smaller orders, a structured video audit covers a surprising amount: production lines running (or not), the warehouse, the QC station, and the person who will actually sign your contract. Ask for it live, not pre-recorded, and ask to see the specific machine that would produce your product.

4. Treat the sample as a test of process, not just product

A good sample tells you the supplier can make one good unit. What you actually need to know is whether they can make ten thousand consistent units. Two habits help:

• Ask the sample to be made on the production line, not in a dedicated sample room.
• Define your acceptance criteria in writing before the sample is made — material grade, dimensions with tolerances, finish, packaging — so the sample is judged against a standard instead of a feeling.

Remember that the sample stage is also when you should agree on how the goods will be inspected at the end: a pre-shipment inspection against the approved sample and the written specification is the standard last line of defense, and it is far cheaper than a rejected container.

5. Set up payment terms that limit your downside

Payment structure is risk allocation. Common structures in China trade include a deposit (typically around 30%) with the balance paid against a copy of the bill of lading, or safer instruments such as letters of credit for larger orders. Whatever the split, two rules protect you more than any negotiation:

• Pay only to the company's corporate bank account, and check that the account name exactly matches the name on the business license you verified in step 1. A request to pay a personal account, a different company, or via informal transfer channels is one of the clearest red flags in this trade.
• Keep the first order small. No verification method is perfect; a modest first order is your own final check, and a good supplier will understand that.

6. Red flags worth walking away from

• Price far below every other quotation you have received for the same specification
• Pressure to pay a personal account or to skip the deposit structure
• Refusal to do any live video walk-through of the workshop
• Business license details that do not match the company name on the quotation or bank account
• No written specification or contract — "trust me, same as sample" is not a quality standard

How a local sourcing agent fits in

Every check above can be done remotely. What a locally based sourcing agent adds is presence: visiting the factory to confirm it is real, sitting across the table when terms are negotiated, following production week by week, and inspecting goods before the container door is closed. That is the practical difference between verifying a supplier on paper and verifying them on the ground.

Yzsource is an independent sourcing service based in Shijiazhuang, Hebei — close to the province's major industrial clusters such as wire mesh in Anping, fasteners in Yongnian, and dozens of others. We do not promise perfect suppliers; no one honestly can. What we do is run the checks described above on your behalf and tell you what we actually find. If you are evaluating a new supplier, send us the company details and we will tell you plainly what can and cannot be verified.
