How to Verify a Chinese Factory Is Real and Not a Trader: 8 Practical Tests

The difference between a factory and a trader is not just price. A trader cannot change anything on the production line, does not carry responsibility for defects, and in a dispute either disappears or blames the original factory you have never met. Here are eight tests we actually use at our Guangzhou office.

1. Ask for the Chinese Business License

Every legitimate Chinese company has a Business License showing the company name in Chinese, a unified code, registered capital and scope of business. The key words in the scope: 生产 (manufacturing) versus 贸易 (trading). A trader usually stalls or sends an unreadable image.

2. Examine the product range

A real factory specialises. A bag factory makes bags — it does not also sell you headphones, watches and kitchenware. A very broad catalogue is the clearest sign of an intermediary.

3. Ask for live video — not recorded clips

Request a live video call from inside the production line, and ask them to walk to specific areas you choose. A trader will make excuses or send a polished clip with music.

4. Ask precise technical questions

Ask about the machine type used, daily output capacity, scrap rate and mould changeover time. A factory answers immediately and confidently; a trader says "let me ask the engineer and get back to you".

5. Verify the address

An address in a downtown office tower means a trading company. Factories sit in industrial zones on city outskirts. Look the address up on maps and see what kind of place it is.

6. Ask for a Chinese VAT invoice (增值税发票)

Legitimate exporting factories can issue a tax invoice in their own name. Small intermediaries often cannot, or issue it under a third company's name — which is a clear signal.

7. Ask for system and test certificates

Such as ISO 9001 or test reports from recognised laboratories. What matters: confirm the company name on the certificate matches the company you are dealing with — many send another factory's certificates.

8. The site visit — the decisive test

Nothing replaces a visit. If you cannot travel, appoint someone to visit on your behalf. A visit reveals in an hour what correspondence hides for a month: actual factory size, equipment condition, worker discipline and storage practices.

Quick red flags 🚩

• A price far below market average with no logical explanation.
• Insistence on transfers to a personal account, or a Hong Kong account in an individual's name.
• Refusing to send a sample, or demanding an excessive fee for one.
• The company name changing between the email, the invoice and the bank account.
• Time pressure: "the offer ends today" — that is a sales tactic, not a manufacturing one.

In summary

Verification costs you days; skipping it costs you a shipment. No single test is sufficient on its own — but four or five of them together give you a very clear picture.
