The short answer
To verify a Chinese supplier, confirm four things before you pay: that they are a real registered company (business license), that they are the actual manufacturer rather than a trading company reselling, that the factory and capacity genuinely exist (audit, live video or third-party inspection), and that their certificates and references are genuine. Never wire a deposit until all four check out.
Why verification matters
In China sourcing you almost always pay a deposit before you receive anything, across distance, language and different legal systems. That makes verification the single highest-leverage step in the whole process: it protects the money you send, and the far larger cost of receiving the wrong product from the wrong supplier. Most sourcing losses are not dramatic fraud — they are ordinary buyers who skipped verification and paid a trading company posing as a factory, or a supplier that could not actually make what it promised.
The four pillars of verification
Every reliable check falls into one of four areas:
- Identity — is this a legally registered company, and are you paying that same entity?
- Manufacturer vs. trader — do they own the production, or resell another factory’s goods?
- Capability — does the factory, equipment and capacity to make your product at your volume actually exist?
- Credentials — are the certificates, test reports and references real and relevant to your market?
A supplier can pass one and fail another — a real company that is only a trader, or a genuine factory with fake certificates — so all four matter.
A step-by-step verification process
Work through these in order; stop and resolve anything that fails before moving on.
- Get and check the business license — confirm the legal name, registration number, business scope (it should cover manufacturing your product) and that it is active.
- Confirm you are paying that same company — the bank account name must match the license; treat any personal or third-party account as a stop sign.
- Prove the factory exists — request a live video walk-through of the production line, or the address to cross-check on maps and export records.
- Order a paid sample — evaluate real quality and confirm they can make your exact spec.
- Match capacity to your order — ask about lines, workers and monthly output, and whether your volume fits comfortably.
- For larger orders, commission a third-party inspection or factory audit before you release the balance.
How much verification your order needs
| Order size | Recommended verification |
|---|
| Small trial (under ~$5k) | Desk check: license + live video tour + paid sample |
| Medium (~$5k–$50k) | Above + reference checks + pre-shipment inspection |
| Large ($50k+) | Above + third-party factory audit before the deposit |
Scale the effort to what you are risking. A small trial order is itself a form of verification; a large or ongoing relationship justifies an independent audit.

FAQ
How do I check a China supplier’s business license?
Ask for the license and verify the registered name, unified social credit code, business scope and status. The scope should cover manufacturing your product, and the account you pay must match the license name.
How can I tell a manufacturer from a trading company?
Ask detailed technical and process questions, request a live tour of the specific production line, and check whether the business scope and certificates match the product. Traders tend to deflect technical questions and avoid showing the floor.
Do I need to visit the factory in person?
Not always. For small and medium orders, a live video tour plus a paid sample and a pre-shipment inspection is usually enough. For large or ongoing orders, an in-person visit or a third-party audit is worth the cost.
Is a business license enough to trust a supplier?
No. A license proves the company exists, not that it makes your product well or at your volume. Combine it with a sample, a factory check and, for big orders, an inspection.
