How to verify a supplier in China before you pay

A practical checklist to tell a real factory from a reseller — and avoid the most expensive mistake small importers make.

May 20, 2026

The single most expensive mistake a first-time importer makes is wiring money to a "factory" that turns out to be a middleman — or worse, no one at all. Before any payment leaves your account, here is how we check that a supplier is real and worth working with.

1. Confirm they make what they sell

Many sellers on large marketplaces are trading companies, not manufacturers. That is not always bad, but you should know which one you are talking to. Ask for the product line they actually produce, the factory location, and photos of the production floor — not stock images. A real factory can answer specific questions about materials, tolerances and lead times without hesitating.

2. Check the business, not just the chat

A legitimate Chinese supplier has a registered business license. Ask for it, and confirm the company name matches the bank account you are asked to pay. A mismatch between the company you are talking to and the account receiving your money is the clearest red flag there is.

If the product talk is great but the paperwork is vague, slow down. The paperwork is the product.

3. Order a sample first

No matter how good the photos look, order a sample before committing to a production run. A sample tells you about quality, but it also tells you about the supplier: how fast they respond, how carefully they pack, and whether the thing in the box matches the thing in the listing.

4. Put someone between you and the factory

This is where most small importers are at a disadvantage — they are thousands of miles away, in a different time zone, reading messages through a translation app. Having a person on the ground in China who can call the supplier, visit if needed, and inspect the real product changes the dynamic completely. Suppliers behave differently when they know someone local is watching.

The short version

Verifying a supplier is not about being paranoid — it is about removing the few risks that can sink a small order. Do these four things and you have already avoided the mistakes that cost most first-time importers their first shipment.
