Before you pay a Chinese supplier, you need to confirm three things: the company legally exists, it is the actual manufacturer (not a middleman), and it can make your product to spec. This guide gives US importers a 12-point verification checklist — from business licence and credit checks to factory audits, sample testing, IP protection and payment red flags — so you can separate genuine factories from risky listings before money leaves your account.
In short: To vet a Chinese manufacturer, verify its business licence and legal name, confirm it is a factory rather than a trading company, run a credit and history check, audit the factory (remotely or in person), test a real sample, lock down IP and contract terms, and watch for payment red flags. Work through the 12 points below before you send any deposit. If a supplier resists basic verification, treat that as your answer.

Why does vetting a Chinese manufacturer matter so much?
Most sourcing problems — quality failures, disappeared deposits, products that don't match the sample — trace back to skipping verification at the start. On platforms like Alibaba, a polished listing tells you almost nothing about whether the company behind it is a real factory, a trading company reselling someone else's goods, or worse. For US importers wiring deposits across the world, a few hours of due diligence is the cheapest insurance you will ever buy.
The 12-point manufacturer verification checklist
1. Verify the business licence
Every legitimate Chinese company has a business licence with a Unified Social Credit Code (an 18-character number). Ask for a copy and confirm the legal company name, registered address, registered capital, and approved business scope. The business scope must actually include manufacturing your product category — not just "trading."
2. Confirm the legal name matches who you're paying
The company name on the business licence, the bank account you wire to, and the sales contract should all match. A mismatch — for example, paying a personal account or a different company — is one of the most common scam patterns. Insist on paying the registered company's corporate account.
3. Factory or trading company? Run the test
Ask direct questions a real factory can answer instantly: What is your monthly production capacity? How many production lines? Can you show the workshop on a live video call right now? Trading companies stall, redirect, or only show finished goods. There's nothing wrong with using a good trading company — but you must know which you're dealing with, because it affects price, control and quality.
4. Pull a third-party credit report
Services that source Chinese corporate records can return registration status, paid-up capital, legal disputes, and whether the company is flagged as abnormal. A cheap company verification report often surfaces red flags that a glossy profile hides.
5. Check how long they've really operated
Cross-check the founding date on the business licence against platform "years as gold supplier" claims. A company registered three months ago presenting as a 10-year exporter is a serious warning sign.
6. Audit the factory — remotely or in person
Arrange a live video walkthrough of the production floor, or commission an on-site factory audit. A real audit checks machinery, staffing, certifications, QC systems and whether the address is a factory at all (not a residential unit or empty office). This is the single highest-value step — our quality control and factory audit service does exactly this on the ground.
7. Verify certifications independently
If a supplier claims ISO 9001, BSCI, or product-specific marks (FCC, UL, FDA registration for your US market), ask for the certificate number and verify it with the issuing body. Certificates are easy to fake; verification is not.
8. Order and test a real sample
Never approve mass production from photos. Order a paid sample, test it against your specification, and — for regulated products entering the US — have it lab-tested against the relevant CPSC, FCC or FDA requirements. Keep the approved sample as your quality reference.
9. Lock the specification in writing
Provide a detailed product specification sheet (materials, dimensions, tolerances, packaging, labelling). Vague specs are how "it matched the sample" disputes start. The spec becomes the standard your pre-shipment inspection is judged against.
10. Protect your IP before you share designs
For custom or branded products, use an NNN agreement (non-disclosure, non-use, non-circumvention) suited to China, and register your trademark in China if you're producing your brand there. Don't send full designs to unvetted suppliers.
11. Structure payment to limit risk
Avoid 100% upfront. Common terms are 30% deposit / 70% before shipment, ideally with a pre-shipment inspection before the balance. Use traceable bank transfers to the verified corporate account, or platform escrow / Trade Assurance where available. Be wary of any push to pay a personal account or change bank details mid-deal.
12. Run a pre-shipment inspection
Before the balance payment and before goods leave China, commission a third-party pre-shipment inspection against your spec and an AQL standard. It's your last checkpoint to catch defects while you still have leverage — the unpaid balance.
Quick due-diligence reference table
| Check | What confirms it | Red flag |
|---|---|---|
| Business licence | 18-digit code, matching name & scope | Won't share, scope is "trading only" |
| Payment account | Registered corporate account | Personal account / changed details |
| Factory vs trader | Live workshop video, capacity answers | Only shows finished goods, evasive |
| Certifications | Verified with issuing body | Certificate "on file," no number |
| Sample | Tested against written spec | "Trust the photos," no sample |
| Payment terms | Deposit + balance after inspection | 100% upfront demanded |
What are the biggest red flags when vetting a supplier?
Watch for: refusal to share the business licence, requests to pay a personal or third-party account, prices dramatically below every other quote, a sudden change of bank details by email, reluctance to allow a video factory tour, and pressure to skip the sample or inspection. Any one of these warrants pausing the deal; two or more means walk away. If you are still at the stage of building a shortlist, our guide on how to find manufacturers in China pairs naturally with this checklist.
Frequently asked questions
How can I tell if a supplier is a factory or a trading company?
Ask for the business licence (the business scope reveals manufacturing vs trading), request a live video of the production line, and ask detailed capacity questions. Real factories answer specifics instantly; traders deflect.
Is Alibaba verification enough to trust a supplier?
No. Platform badges like "Verified Supplier" or "Gold Supplier" are a starting filter, not proof of capability or honesty. Always run independent checks — business licence, credit report, sample and audit — and apply the same rigour to quality control when importing from China.
Do I need to visit the factory in person?
Not necessarily. A thorough remote audit — live video walkthrough plus a third-party on-site inspection — covers most of what an in-person visit would, at a fraction of the cost. In-person visits add the most value for large or complex orders.
How much does it cost to verify a Chinese manufacturer?
A company credit report is typically modest; a third-party factory audit or pre-shipment inspection runs a few hundred US dollars. Against a four- or five-figure order, this is inexpensive protection. Verifying the supplier also helps you land goods at the right declared value — see our worked examples for import duty to Ireland and import duty to the UAE.
What's the safest way to pay a new supplier?
Use a deposit-plus-balance structure with a pre-shipment inspection before the final payment, paid by traceable transfer to the verified corporate account or via platform escrow. Never pay 100% upfront to an unverified supplier.
