China Supplier Due Diligence Checklist Before Onboarding or Payment

Scope the check to the decision

A useful supplier due-diligence checklist begins with the decision the buyer is about to make. Screening a company before requesting a sample requires less evidence than approving a large deposit, transferring tooling, signing an exclusive agreement, or onboarding a long-term supplier. The depth of verification should increase with the commercial and operational risk.

Record the product, expected order value, payment stage, destination market, critical standards, and consequences of failure. This creates a clear scope and prevents the investigation from becoming a collection of facts that are interesting but unrelated to the actual purchasing decision.

Verify identity and transaction responsibility

Confirm the supplier’s registered Chinese legal name, Unified Social Credit Code, current registration status, establishment date, registered address, legal representative, and business scope. Connect the English name, website, email domain, B2B profiles, quotation, contract, invoice, and proposed payment account to that legal entity.

List every other company involved in sales, manufacturing, export, invoicing, or payment. For each entity, record its role and the evidence of its relationship to the proposed contracting company. Do not transfer a factory capability, certification, trade record, or liability from one entity to another without support.

Review capability and operating evidence

Review whether the supplier’s operating evidence fits its claims. Depending on the order, this may include product specialization, technical staff, recruiting activity, certifications, patents, tender records, trade-fair participation, customs or trade signals, factory addresses, equipment claims, social-media activity, and consistency across Chinese and English channels.

Separate marketing statements from independently checkable evidence. A website can demonstrate positioning and product knowledge, while a registry, certification database, tender notice, recruiting record, or shipment signal may provide a different type of support. No single source should carry the entire conclusion.

Check risk signals and consistency

Check relevant public risk and status information, but interpret it in context. Confirm that a record belongs to the correct legal entity, note the date and source, and distinguish an unresolved lead from a verified finding. A missing public record should not be presented as proof that no risk exists.

Compare claims across sources and document inconsistencies. Important questions include whether company age matches claimed experience, whether certifications belong to the contracting entity, whether the payment recipient is expected, whether factory evidence points to another company, and whether product and staffing signals support the claimed operating scale.

Convert findings into next actions

Translate every material uncertainty into a follow-up action. The action might be requesting an original document, confirming bank details through a known contact, asking the supplier to explain an entity relationship, ordering a sample, checking a reference, conducting a video call, arranging a factory audit, or scheduling a pre-shipment inspection.

Finish with a decision record rather than a simple pass-or-fail label. State what was verified, what remains uncertain, which sources were used, when the information was checked, and what must happen before the next commitment. This makes the due-diligence work traceable and easier to update if the order, entity, or risk level changes.
