Supplier Verification Checklist for Sourcing from China

A business licence, factory photograph or marketplace badge answers only one question. Supplier verification is a layered process: establish who the counterparty is, what it is authorised and able to do, whether its claims match independent records, and how the proposed transaction will control the remaining risks. No single database search proves that a supplier will deliver the right goods.

The checklist below is designed for an overseas buyer preparing a real purchase. The depth should follow product, country, value, safety and payment risk. A low-value standard item and a regulated medical device should not pass through the same review.

1. Freeze the requirement before checking candidates

Write the model, drawings, materials, dimensions, tolerances, performance, quantity, packaging, destination, intended use and target timing. Identify mandatory destination standards, import permits and prohibited features. Separate “must have” requirements from preferences. Verification without a stable brief can confirm the wrong company for the wrong product.

2. Establish the legal counterparty

• Obtain the Chinese legal name, Unified Social Credit Code, registered address, legal representative and current business licence.
• Search the official National Enterprise Credit Information Publicity System using the Chinese name or code. Review registration status, registered scope and published abnormal-operation or serious-violation entries where available.
• Match the entity across quotation, contract, invoice, company seal and bank beneficiary. Ask for a written explanation of any difference.
• Identify whether the counterparty manufactures, trades, exports, or combines those roles. A trading company is not automatically unsuitable, and the word “factory” is not proof of manufacturing.
• Identify affiliates and subcontractors that will touch the goods, tooling, buyer data or payment.

Public records have limits: they can be incomplete, delayed or difficult to interpret, and an active registration is not a credit rating. Preserve the search date, query and result rather than copying a status into a spreadsheet without evidence.

3. Verify the people and communication channel

Confirm the sales contact through a company-controlled domain, published switchboard, video meeting or another independently obtained channel. Check that contract changes and bank instructions come from authorised people. A familiar email thread can still be compromised. For any beneficiary change, stop the payment workflow and verify it through a previously trusted channel; do not rely on the message announcing the change.

4. Test product and regulatory claims

• List each claimed certificate, test report, licence, registration, patent or trademark and the exact product model it covers.
• Check the issuer, number, holder, manufacturing site, scope, issue date, expiry and status in the issuer or regulator’s official system where one exists.
• Contact the issuer through independently found details when an online check is unavailable.
• Compare photographs, nameplates, manuals, labels and packaging with the documented manufacturer and model.
• Confirm destination requirements independently. A certificate used in one market does not automatically authorise import or sale in another.

A PDF certificate can be altered, valid for a different model, issued to another entity or outside the proposed factory scope. Even a valid management-system certificate does not prove that the production lot meets the buyer’s specification.

5. Verify operating capability

Choose remote evidence, an on-site visit or an independent audit according to risk. Review the actual manufacturing and testing flow, key equipment, calibration, incoming-material controls, qualified staff, capacity constraints, traceability, nonconforming-product control and subcontracting. Ask who owns tooling and who approves changes. Compare observed capability with the quoted lead time and volume.

ISO 19011 provides guidance on audit principles, programmes and competence; it does not turn a brief walk-through into a certification. Define the audit criteria and collect objective evidence. A tidy showroom and a video of machinery do not establish ownership, available capacity or control of the product under order.

6. Run a controlled sample or pilot

1. Approve a written sample specification and identify the sample with model, version and date.
2. Test critical functions and safety requirements using a competent facility when needed.
3. Record deviations and the supplier’s corrective action.
4. Seal or otherwise identify the approved reference where practical.
5. State that bulk production must match the agreed specification, not merely “be similar to the sample”.

A good sample reduces uncertainty but can be specially prepared. The production control plan and release inspection must still address bulk consistency.

7. Review commercial resilience and conduct

Ask for references that the buyer can contact independently, while respecting confidentiality. Review litigation, administrative penalties, adverse media, intellectual-property disputes and abrupt changes in ownership or address where lawful and relevant. Test how the supplier answers technical questions: clear limits and documented uncertainty are more useful than instant agreement to every request.

Protect drawings, brands and buyer information before disclosure. The International Trade Administration notes that companies should develop an intellectual-property strategy for China rather than assume overseas rights apply automatically. Use need-to-know access, confidentiality terms and staged disclosure for sensitive material.

8. Design the transaction controls

• Contract with the verified entity and state specifications, acceptance criteria, change control and document hierarchy.
• Link payments to objective milestones appropriate to the transaction, while recognising that documents alone may not prove physical quality.
• Define inspection access, hold points, rework, reinspection and release authority.
• Confirm the Incoterms® rule, named place, shipping documents, insurance responsibility and claims process.
• Retain an evidence file containing source records, versions, approvals and communications.

Use a decision record, not a pass badge

Close the review with supported facts, conflicts, unknowns, mitigation and an owner for each open item. A supplier can be suitable for one model or volume and unsuitable for another. Recheck time-sensitive information before payment, production release and shipment. Verification supports a purchasing decision; it does not guarantee future performance or replace legal, regulatory, technical and financial review.
