How to Verify a Chinese Supplier: Evidence and Scorecard
A supplier qualification matrix that separates identity, capability, samples and order terms. Download the evidence worksheet before approving an order.
Verify a Chinese supplier by checking the legal business identity, matching it to the proposed contracting and payment parties, assessing product-specific manufacturing capability, and reviewing samples and commercial terms. Treat these as separate checks. Registration can help establish who a business is; it does not prove that it can produce your specification or perform your order reliably.
The Sourcing Lab Supplier Evidence Matrix below is an original editorial worksheet, introduced on September 14, 2026. It is not an industry standard, an audit certificate or a list of approved factories. Download the blank supplier evidence worksheet.
What company information should you request?
Request the Chinese legal name, Unified Social Credit Code, business license details, registered address, proposed production site, and the name of the entity issuing the quotation. Compare the business identity against the official National Enterprise Credit Information Publicity System. Its regional portal supports searches by enterprise name, credit code or registration number. Access may require interactive verification or local assistance.
Record the source and date of the check. Keep the legal name separate from an English trading name or marketplace display name. If the supplier, exporter, seller or bank beneficiary differs, ask for a documented explanation and have the arrangement reviewed before payment. Do not publish sensitive business or banking documents in a public scorecard.
What evidence belongs in a supplier scorecard?
Use one row per question, with a document reference and named reviewer. Mark evidence as missing, supplier-provided, cross-checked, or contradictory. Cross-checked means compared with another relevant source; it does not mean risk-free.
| Area | Evidence to request | What it can support | What remains unresolved |
|---|---|---|---|
| Identity | Legal name, registration identifier, quotation entity | The identity being proposed | Whether the order will be performed |
| Production fit | Process description, proposed site, subcontracted steps | A capability discussion for this product | Whether stated capacity is available |
| Specification | Written response to the same brief revision | Which requirements the supplier accepts | Whether production will match them |
| Samples | Identified sample with measured review notes | Selected appearance, dimensions and construction | Consistency across the production lot |
| Test documents | Report identity, issuer, date, product and scope | Evidence relevant to the tested item | Applicability to changed materials or models |
| Commercial terms | Seller, price basis, payment and delivery terms | Responsibilities proposed for the order | Ambiguities requiring contract review |
| Issue handling | Written correction and escalation process | A proposed way to handle discrepancies | How a real dispute will be resolved |
Do not give a missing document a positive status because the supplier responded quickly. Responsiveness is useful, but it answers a different question from technical suitability.
How can you score the completeness of a review?
For internal planning, count the required questions with a recorded answer and supporting evidence, then divide by the total required questions. If 9 of 12 have that evidence, the file is 75% complete. That number describes documentation coverage only: it is not a 75% probability of a safe order and cannot override a serious contradiction.
Identify critical questions before requesting quotes. Examples include the identity of the seller, whether a sample meets a non-negotiable requirement, and who owns an unresolved import review. Keep the order decision on hold when a critical answer is missing or contradictory, even if the rest of the file is complete. If a requirement does not apply, record the reason and reviewer instead of silently deleting it.
Factory or trading company: which is better?
Neither label decides the result. A trading company may coordinate several processes; a manufacturer may subcontract a specific finish. Ask who performs each step, who sells to you, what changes require approval, and what evidence is available. Compare the proposed arrangement using the agent and supplier explanation, then evaluate the actual product against the RFQ.
As an illustrative example, a box supplier may provide its own printing but buy inserts elsewhere. That is a question about coordination and component approval, not automatic proof of a problem. Request a complete assembly sample and identify who resolves a fit mismatch between the box and insert.
When do you need an independent inspection or specialist?
Request an independent provider when the decision requires site verification, a formal inspection report, laboratory testing or specialized technical judgment beyond the available evidence. Agree its scope, limitations, product reference and reporting requirements. A video call or production photo should not be described as an independent certified inspection.
Sourcing Lab USA provides sourcing and product supply with order-specific production coordination. This educational guide does not advertise a standalone factory audit or certification service. For the production handoff, use the quality control checklist and documented sourcing method.
What should you recheck before a repeat order?
Reconfirm the contracting and payment parties, specification revision, production site or process changes, materials, sample basis and delivery terms. Keep changes in a revision log. A previous order or an old test report does not resolve every question about a new product or changed material.
