How to Verify a Chinese Supplier: 7 Methods That Actually Work
Every week, buyers wire deposits to Chinese suppliers they've never met, based on a slick Alibaba page and a WeChat conversation. Most of the time it works out. When it doesn't, the loss is usually total — the money is gone, the "factory" doesn't answer, and there's no reasonable legal path to recover it from another country.
The single biggest predictor of whether a deal goes sideways is whether the buyer verified the supplier before paying. Here are the seven methods that actually work, from free public checks to full third-party reports.
1. Get the business licence — and read it properly
Every legitimate Chinese company holds a business licence (营业执照) issued by the local Administration for Market Regulation. Ask for a clear scan. The details that matter:
- Unified Social Credit Code — an 18-character identifier. This is the key that unlocks every other government database.
- Legal representative — the person legally responsible for the company.
- Registered capital — a company claiming to run a large factory with RMB 10,000 (~$1,400) in registered capital is a red flag.
- Establishment date — a "10-year-old manufacturer" registered six months ago is not a manufacturer.
- Business scope — real factories have 生产 (production) or 制造 (manufacturing) in scope. Trading companies have 贸易 (trade). This is written on the licence.
If the supplier refuses to send the licence, or the details don't match anything they've told you, stop there.
2. Cross-check on the GSXT government database
The National Enterprise Credit Information System — GSXT — is the Chinese government's public register of every company in the country. Enter the Unified Social Credit Code and you'll see the same registration data the licence claims, plus annual reports, shareholder structure, administrative penalties, and any "abnormal business" listings. If any of these don't match the licence the supplier sent you, the licence is fake or edited.
The catch: GSXT is entirely in Chinese, search only accepts the exact Chinese company name or code, and the interface is not friendly. But it is the authoritative source.
3. Search court and enforcement records
China's court judgements are public through China Judgements Online (中国裁判文书网) and the Supreme People's Court enforcement system. Search the supplier's Chinese name and you'll see:
- Contract disputes filed by other buyers — a pattern of these means the same is likely to happen to you.
- Labour disputes — a lot of these often means unpaid wages, which often means cash flow problems.
- Enforcement cases (被执行人) — the supplier lost a lawsuit and didn't pay. This is a serious signal.
- IP infringement suits — often a sign the "manufacturer" is copying someone else's product.
One or two old cases is normal for any company that has done real business. Dozens is not.
4. Check the tax credit rating
Chinese tax authorities grade every company A, B, C, or D each year based on tax compliance. Only 5–8% of companies earn an A. Most legitimate businesses are B. A C-rated company has had filing or payment issues. A D-rated company has committed tax fraud or repeatedly failed to file. A company willing to cheat the tax bureau is a company willing to cheat you.
5. Actually look at the factory — physically or on video
A supplier's registered address is on the licence, in Chinese. Paste it into Baidu Maps or Amap (高德地图) and check the satellite view. A real factory looks like a factory: large industrial building, loading bays, worker dormitories nearby. An office tower or residential compound is not a factory.
Then get a live, unscripted video call from the production line — your product visible, workers you can see, and the person on camera pointing the phone at whatever you ask. Not a pre-recorded tour. Not photos. Middlemen rarely pass this test, and when they do, the "factory" often turns out to be a workshop they rent for exactly this purpose.
For higher-value orders, hire a third-party audit firm (SGS, Bureau Veritas, TUV, AsiaInspection). $300–$1,500 depending on scope. Cheap insurance on a $30,000 order.
6. Ask for — and verify — trade references
Any real supplier has customers who will vouch for them. Ask for two or three buyers in your region and call them. Useful questions: How long have you been buying? Any quality issues, and how did the supplier handle them? Any pricing surprises mid-order? Would you order again?
Verify the references exist. A "customer" with no website, no LinkedIn, and no findable public presence is often the supplier's cousin.
7. Order an independent verification report
All six methods above take days, require Chinese, and produce raw data you still have to interpret. A proper third-party report does the work in one place: business licence verified, government database cross-checked, court and enforcement records pulled, tax rating decoded, penalties listed, address confirmed, and a clear recommendation at the end.
This is what FactoryChecker does. We run these checks — plus product certifications, ISO verification, export licence, and 1688 transaction history — on any Chinese supplier you send us. You get a plain-English report before you send a deposit, for a flat $129. That's roughly 0.4% of a typical first order. If the supplier is legitimate, you get peace of mind. If they're not, you get the single most valuable email of the quarter.
Which methods for which situation
Small first order under $5,000, cautious buyer: methods 1, 2, and 8 (the video call). Cost: your time, plus about $129 if you outsource.
Standard order, $5,000–$50,000: methods 1–4 plus a video call, or a full verification report. Skip the on-site audit unless you're doing repeat business.
Large order, ongoing relationship, or private-label brand: full report plus a physical on-site audit. Add pre-shipment inspection on every batch.
The one thing that costs you every time
Skipping verification because the supplier "seems nice" is the single most expensive mistake in China sourcing. Nice suppliers scam people every day. Rude suppliers deliver on time every day. Vibe is not a verification method.
