China Supplier Verification Checklist (2026 Buyer Guide)

Important: this is a commercial sourcing checklist, not legal, accounting, certification, or regulatory advice. Verification reduces avoidable uncertainty; it cannot guarantee that a supplier is safe.

1. Verify the supplier’s identity

Start by confirming that the salesperson, website, contract, invoice, and payment beneficiary all point to a coherent legal and operating entity.

Legal name is recordedAsk for the exact Chinese legal name and unified social credit code, not only an English brand name. Business licence details agreeCompare the legal name, code, address, scope, registration status, and date with other records. A copy alone is not proof. Contact details are consistentCheck domain, email domain, phone, WeChat identity, address, salesperson name, and company name across platforms. Contract and invoice matchThe selling entity, invoice issuer, and beneficiary should be explainable. Written clarification is needed if they differ. Ownership and history are plausibleLook for unexplained recent creation, frequent name or address changes, or a brand-new sales profile behind an old claim.

2. Test the factory claim

“We are a factory” is a business-model claim that should agree with the location, equipment, staff, capacity, and documents you observe.

Production address is statedAsk for the full factory address and compare it with the licence, website, quotations, and any visit plan. Factory versus trader status is clearA trading company can be legitimate. The concern is a misleading claim, not simply the business model. Relevant equipment is evidencedRequest photos or video showing the claimed machine type, product in production, and a way to connect the evidence to this supplier. Capacity claim fits the orderCompare requested quantity and lead time with lines, staffing, shifts, peak periods, and other evidence. On-site verification is consideredBook a visit when factory location, equipment, process, capacity, or subcontracting is central to the payment decision.

3. Check product fit and capability

A supplier can look established and still be a poor fit for your product. Ask for evidence specific to what you intend to buy.

Similar products are evidencedLook for relevant specifications, production images, samples, customer references where permitted, and answers to technical questions. Specification questions are answeredMaterials, dimensions, tolerances, functions, finish, packaging, and customisation should receive specific answers. Price and terms are credibleCheck MOQ, tooling, sample cost, payment schedule, lead time, packaging, and what is excluded from the quote. Quality process is describableAsk who checks incoming materials, first output, work in progress, final goods, and nonconforming products. Your compliance needs are identifiedDo not assume a supplier’s document meets your destination market. Confirm required testing and certification with a qualified provider.

4. Stop for unexplained payment and authority red flags

Urgency and authority changes deserve special attention because they can bypass the normal evidence collection.

Bank beneficiary is understoodConfirm the legal relationship between the supplier, contract, invoice, and bank beneficiary in writing. Bank-detail changes are independently confirmedDo not rely on an email or chat reply alone. Use a previously established channel to confirm a changed account. Personal-account pressure is explainedA request for payment to an unrelated personal account should pause the process even when the reason sounds convenient. Signatory authority is clearKnow who can sign the contract and approve changes, especially for tooling, deposits, and account details. Artificial urgency is tested“Pay now or lose the price” is not evidence. Ask for the offer in writing with validity, scope, and conditions.

5. Send five questions before the deposit

A useful reply is specific and internally consistent. Copy these into your supplier conversation:

What is your exact Chinese legal name and unified social credit code?
Are you the manufacturer, a trading company, or a mixed model—and who produces which process?
Which production address will make our order, and what evidence can connect it to this company?
Who will inspect and approve the first output and final goods, using what checklist?
What is the exact contract, invoice, and bank beneficiary relationship?

6. Decide: green, amber, or red

Do not turn a list of documents into a false sense of safety. Make the decision depend on the evidence that matters for this order.

GREENIdentity, fit, and key claims are consistent; remaining uncertainties are non-critical and understood.

AMBERA central claim is unsupported or contradictory. Gather evidence or arrange a visit before paying.

REDMaterial identity, authority, beneficiary, or capability concerns remain unexplained. Stop.

Remember: the goal is not to make a supplier look perfect. It is to expose what is known, what is still missing, and what that means for your next payment.
