12-Point Checklist for Vetting a Chinese Mold Maker
Huangshi Mold Hub Editorial Team · Published and source-reviewed
Before buying extrusion tooling from China, verify the company you will contract with, its relevant manufacturing capability, the acceptance plan and the payment beneficiary. This 12-point checklist turns those questions into documents and checks you can record before a deposit, during technical negotiation and before final payment. A directory listing or marketplace badge is a starting point for research, not proof that a factory can deliver your profile.
Before You Contact: 4 Document Checks
1. Match the business license to the contracting entity
Request the registered Chinese company name, unified social credit code and license copy. Search the official National Enterprise Credit Information Publicity System using those identifiers. Record the result and date; access can require interactive verification. Resolve differences between an English trading name and the legal entity before signing.
Registration establishes identity, not manufacturing competence. The US International Trade Administration’s due-diligence guidance supports researching potential business partners rather than relying on introductions alone.
2. Review attributable export evidence
Ask for redacted commercial documents for comparable tooling shipments, with dates and company identity visible. A trading company may legitimately export for a manufacturer; identify who designs, trials, invoices and warrants your tooling. Obtain permission before contacting a reference customer.
3. Cross-check shipment and customs records where available
Use relevant third-party trade records as supporting evidence. Match entity names and product descriptions carefully. An absent record may reflect limited database coverage or an intermediary exporter; it does not establish that the company has never exported. Likewise, a shipment of unrelated goods does not prove extrusion-die capability.
4. Assess marketplace history without treating it as an audit
Check account ownership, published product scope and any transaction or assessment information that is actually visible. Save dated records of the claims you rely on. Read the protection terms applicable to your order, including the payment route and dispute deadlines. Never assume a badge covers your tooling acceptance criteria.
During Negotiation: 5 Technical Checks
5. Confirm steel and treatment in writing
Identify grades and governing standards for melt-contact plates, calibrators, inserts and supports. Request certificate traceability and heat-treatment or surface-treatment records. Decide whether independent analysis is needed. The steel guide explains why “nitrided” and “corrosion-resistant” are different specifications.
6. Define the trial policy
Specify included trial runs, compound supply, sampling, measurement and shipping. Define the labels T0 and T1 in the project documents; labels alone do not set acceptance. Ask for the intended line conditions and agree how changes will be recorded.
7. Agree measurable tolerances and acceptance
Attach the drawing revision, critical dimensions, surface criteria and functional checks. State the measurement method and sample-conditioning requirements. Approve the intended production compound and target output. Use the trial guide to build a report that relates each result to an acceptance requirement.
8. Allocate correction and redesign costs
Separate correction of a supplier’s failure to meet the agreed specification from buyer changes to geometry, material or output. Document the approval process, additional costs and schedule impact. Also record tooling ownership, storage, maintenance and the information supplied if you move the tooling to another plant.
9. Make the schedule auditable
Request milestone dates for drawing approval, machining, first trial, corrective work, acceptance and dispatch. Agree what happens after a delay and how changes are authorized. Commercial remedies should be reviewed for your contract; a claimed lead time on a product page is not a project commitment.
Before Final Payment: 3 Shipment Checks
10. Approve identifiable samples and reports
Match sample labels to the tooling set, trial date, compound batch and report. Review physical samples where critical fits require them. Record acceptance or remaining deviations in writing, including any condition that must be closed before shipment.
11. Verify the actual shipment
Use a risk-appropriate inspection to confirm tooling identity, agreed components, documentation, packing and preservation. If an independent inspector is appointed, provide the acceptance plan and access requirements beforehand. Inspection should address your order rather than offer only general workshop photographs.
12. Confirm payment milestones and the beneficiary
Match payment documents to the contract and resolve any intermediary arrangement. Independently verify a changed bank account using an established channel. The FBI’s business email compromise guidance describes how genuine business conversations can be exploited for fraudulent payment requests.
No universal 30/70 payment split is asserted here. Negotiate release conditions around identifiable deliverables, and understand which document demonstrates inspection, shipment or delivery. A bill of lading does not by itself prove tooling performance.
| Stage | Checks | Record to retain |
|---|---|---|
| Before contact | 1–4: identity, exports, trade records, marketplace evidence | Dated records and unresolved differences |
| Negotiation | 5–9: steel, trials, acceptance, changes, schedule | Agreed specifications and signed order documents |
| Before payment and shipment | 10–12: samples, inspection, beneficiary | Acceptance record, inspection findings and payment verification |
Red Flags: Pause the Order if You See These
Pause when the supplier will not identify the contracting entity, cannot explain its manufacturing role, refuses reasonable access to the work or cannot specify steel and acceptance conditions. Unexplained beneficiary changes and pressure to bypass agreed payment procedures deserve immediate independent checking.
A request for full advance payment or reluctance to show proprietary workshop areas is a reason to investigate context, not automatic proof of fraud. Ask for alternative evidence and decide whether the unresolved risk is acceptable before proceeding.
Keep a PDF Copy with Your Order File
Request the free supplier-vetting PDF by email. It provides space for evidence, exceptions and sign-off at each stage. You can also request the companion trial checklist from the same form.
Browse Zhongjie, Hongxing and Kunsheng for their published product scope. Read the cost comparison guide before assessing quotations. When your specification is ready, select suppliers for an RFQ; directory inclusion does not replace these checks.
Frequently Asked Questions
How much deposit is normal for a Chinese mold maker?
There is no independently verified directory-wide deposit percentage. Negotiate staged payments tied to documented deliverables, and assess the amount at risk before each release. A familiar percentage is not evidence that an order is safe.
Can I use a video factory audit instead of flying over?
A live walkthrough can screen capability. Ask to see the workshop, tooling under manufacture, inspection equipment and trial line, with the date and your project identified. Video cannot replace independent inspection where that is required.
What payment method is safest?
No method removes all risk. Compare bank transfers, letters of credit and applicable marketplace protections with your bank or adviser. Verify the beneficiary independently and check protection terms, exclusions and dispute deadlines before paying.
What if the supplier stops responding after the deposit?
Preserve the contract, invoices, messages and payment evidence. Contact your bank promptly if fraud is suspected, use any applicable marketplace dispute process, and seek qualified advice on recovery. A directory profile does not guarantee repayment.
