How to Verify a Chinese Supplier

The guide that saves importers from wiring money to a façade. Written and maintained by Sol Research Desk. Last updated: August 2026.

Every year, thousands of first-time importers lose money the same way: they find a "factory" on Alibaba in five minutes, skip verification because the salesperson seemed nice, wire a deposit, and receive a container of unsellable product — or nothing at all.

The professionals don't have better luck. They have a system. This is it, in full.

Why verification matters more in 2026 than ever

Three shifts made supplier due diligence non-optional this year:

1. The US de minimis exemption is gone. Shipments under $800 that used to clear duty-free now require formal entry. Your supplier's paperwork, HS code accuracy, and declared values now get scrutinized — errors cost real money at the border.
2. Platform verification ≠ supplier verification. Alibaba "Verified" badges confirm a company exists and paid for the badge. They do not confirm the company manufactures what it claims, owns its equipment, or will still exist in 90 days.
3. Trading companies now pose as factories more convincingly than ever. AI-generated factory photos, rented showroom tours, and copied certification documents are standard playbooks.

The good news: a disciplined buyer can filter out 95% of bad suppliers before any money moves, in about a week of part-time work, at near-zero cost.

Step 1 — Pull the business license (营业执照)

Every legitimate Chinese supplier has a registered business license. You want three fields off it, and you can verify all of them yourself:

• Unified Social Credit Code (USCC) — the 18-character national ID for the company
• Registered business scope — must include manufacturing (生产/制造) of your product category if they claim to be a factory. A company whose scope says only "trading" (贸易) is a middleman posing as a factory.
• Registered capital and founding date — a 2-year-old company with ¥100,000 registered capital claiming to be "a 15-year factory with 400 workers" is telling you a story.

How to check it free: paste the USCC or the Chinese company name into the National Enterprise Credit Information Publicity System (gsxt.gov.cn) or a commercial registry like Qichacha. Five minutes. If the supplier refuses to send their license at all, you're done — that's a disqualifying red flag, not a negotiation.

Step 2 — Cross-check the certifications

If you sell into regulated markets, the certs matter more than the price:

• US market: FDA registration (food/contact goods), FCC (electronics), CPSIA (children's products), UL/ETL (electrical safety)
• EU market: CE marking with a real Notified Body number, RoHS, REACH

The move everyone misses: certifications are issued to a legal entity. The cert must match the business license name of the company you're paying — not a sister company, not a "partner factory," not a slightly different spelling. Mismatched entity names on certificates are the single most common cover for trading companies posing as manufacturers.

Verify the cert itself, not the PDF: FCC IDs go into the FCC database, CE Notified Body numbers go into NANDO, FDA registrations go into the FDA registration lookup. All public, all free.

Step 3 — The video factory audit

You cannot fly to Shenzhen for every supplier. You can do the next best thing:

• Request a live 15-minute walkthrough (pre-recorded videos are stock-footage playgrounds)
• Ask the guide to show specific stations: the machine that makes your part, the QC bench, the warehouse racks with dated inventory
• Ask one operator to state what the machine is running that day

A real factory does this without drama. A shell company stalls, offers a "virtual tour video," or reschedules forever. Each of those outcomes is data.

Step 4 — References and reviews that actually check out

Ask for two export references in your market — name and email is enough. Then actually contact them. A five-line email to a reference surfaces more truth than a week of chatting with sales.

Cross-reference independently: search the supplier's name on Alibaba's own complaint boards, Scamadviser, and Reddit (r/FulfillmentByAmazon, r/ecommerce are brutally honest). One furious ex-customer is a story; five is a pattern.

Step 5 — Samples against a written spec

Free samples are showroom units. Paid samples are production-line units. Order 2–5 units, pay for them plus express freight, and — critically — attach a one-page spec sheet so the sample is judged against the same document your mass order will be judged against.

The spec sheet doesn't need to be engineering-grade. Material, dimensions with tolerances, weight, finish, packaging, and the test standard it must pass. One page. If the sample deviates from the spec, you've just watched your future quality dispute — while it was still cheap.

Step 6 — Payment structure as the final filter

Verification is never "done" — it's priced into how the money moves:

• Never 100% upfront. Standard structure: 30% deposit, 70% after a passed final inspection (pre-balance-payment photos, or better, a third-party inspector's report)
• Alibaba Trade Assurance for first orders — imperfect, but its dispute mechanism is real leverage
• Wire transfers (T/T) only to a company account matching the business license name. A "factory" asking you to wire a personal account, a different company, or a Hong Kong shell is not a factory you want to pay

The 10-second red flag scan

Before any deep verification, these instantly disqualify:

1. Refuses to share a business license
2. Certificate entity name ≠ business license name
3. Prices dramatically below every other quote (they're pricing what they'll actually deliver)
4. Pressure tactics: "price valid today only," "another buyer is ordering now"
5. WhatsApp-only communication, no company email domain
6. Can't answer a technical question about their own product beyond the brochure
7. Factory address resolves to an office tower or a residential block
8. Payment to a personal or third-party account
9. Sample quality ≠ quote quality tier
10. They agree to every customization instantly — a real factory says "no" sometimes

Three or more of these present, walk away. It's not a negotiation, it's an exit.
