How to Verify a Chinese Supplier Before Paying

Verifying a Chinese supplier means checking three things: that the company exists legally, that its business licence covers manufacturing the product and not just selling it, and that the certifications it displays are issued in its own name. All three can be checked before you pay, and all three rule out most of the middlemen posing as factories.

The reason this matters more than price: whoever subcontracts production does not control your timeline or your quality, and when a defect shows up they negotiate with the factory with the same interest as you in the factory giving ground — which is to say, none.

Step 1: the Chinese business licence

Every company operating in China has a business licence (营业执照, yingye zhizhao) with an 18-digit unified registration number. It is public and can be looked up.

What you need to read is not the name or the registered capital, but the activity scope (经营范围). That is where the difference sits:

• A factory has a scope limited to production and manufacturing of one specific category.
• A trader has a scope limited to sales, commerce or foreign trade.

If the scope says sales and you believe you are buying from a factory, you are buying from a middleman.

Step 2: the entity type and ownership

Check that the entity type is consistent with what they are selling you. A limited liability company (有限公司) is the norm. A “sole proprietorship” (个体工商户) claiming to be a manufacturer of electronics for export is a contradiction.

Also check that the person signing the contract is the registered owner or someone with a verifiable power of attorney. And that the bank account is in the name of the same company that signs. An account in the name of a private individual, or of a different company, is grounds to stop the transaction without further discussion.

Step 3: the certifications

For regulated categories — electrical goods, children’s products, food, cosmetics — certifications are where the lying is heaviest.

The three failures that show up again and again:

Certificates in another company’s name. The supplier shows you a valid certificate, but the holder is a third party. That certificate does not cover your product.

Expired certificates. Very common in 1688 catalogues with years without updates.

Certificates covering a different model. The certificate exists, is valid, is in the right name, but it corresponds to a different reference from the one you are going to buy.

The check is the same in all three cases: look at the holder, the validity date and the model or reference covered, and confirm they match those of your order.

Step 4: catalogue consistency

A real factory has a narrow scope. A trader sells anything.

If the same company offers you phone cases, garden furniture, toys and building materials, it is not a factory: it is a middleman with an assembled catalogue. It is not always a reason to rule them out, but it changes the conversation about price, lead time and liability completely.

Step 5: the factory visit

This is the check that cannot be faked over email. If the order justifies it, visit the plant or arrange an on-site factory verification in your name.

What gets documented on a visit: the building and its size, the main equipment, the production lines, the number of workers, whether there is an in-house quality department and where it inspects. With dated photographs.

A middleman cannot show a production line it does not have. It can rent a building for an afternoon, but that is deliberate fraud — and at that point we are no longer talking about a bad supplier, but about a scam in progress.

The seven red flags

1. Payment to a personal account or to a company different from the one that signs. The most serious of all.
2. A price far below market for the same specification and volume.
3. Reluctance to allow third-party inspection before shipment, or excuses to delay it.
4. Reluctance to allow a factory visit with vague reasons: “we are renovating”, “the plant is in another province and it is not worth the trip”.
5. A licence scope incompatible with what it claims to manufacture.
6. Certifications from another holder, expired, or for another model.
7. A change of bank details mid-transaction. This is the classic pattern of compromised-email fraud. If you receive an email saying the account has changed, verify it through another channel before you move a single dollar.

How to verify a supplier you found yourself

If you already have a supplier identified on 1688 or Alibaba and you want to check it before paying, the verification can be hired independently, without needing to change your sourcing agent or buy through anyone at all.

The useful deliverable is not a “verified supplier certificate”, but a report that states explicitly: this is what we checked, this is what we found, and this is our assessment of whether this plant can produce your product.

What to do when the supplier fails

You rule it out and document why, so you do not stumble into it again.

This is a frequent outcome, not a failure of the process. In many 1688 categories, most listings that look like a factory are traders. Catching that before you pay is exactly the value of running the check, and the cost of the verification is a fraction of the cost of an order paid to the wrong party.
