How to tell a factory from a trading company in China
A trading company answers email and quotes you a price. A factory owns the machines that make the product. On paper the two can look alike, because both hold a Chinese business licence and both can send a polished catalogue. The difference shows up in the registered business scope, in the number of people on the payroll, and in what happens when you ask to see the production line.
Why the difference matters
Buy from a trading company and you pay a margin to a middleman who does not control the line. When a defect appears or a delivery slips, the person you deal with cannot walk to the machine and fix it. You also lose sight of the real cost, because you only ever see one marked-up price.
Trading companies are not automatically bad. Some hold stock, write clear English and handle export paperwork you would rather not touch. The risk is paying factory prices and trusting factory promises while someone else controls production.
How do I check if a supplier is a real factory?
Start with the business registry, then confirm on the floor. The registry says what a company is allowed to do. The floor says what it actually does. Neither is enough on its own.
- Read the registered business scope. Every Chinese company has a scope of permitted activities on its licence. A manufacturer lists production of the goods. A trading company lists wholesale, retail or import and export. If the scope says trading, the company may still own a factory under a related entity, so keep reading the other checks. Our separate guide explains how to pull this record from the official registry.
- Check the number of insured employees. The annual report a company files with the registry includes a headcount. A factory that runs a line usually reports dozens or hundreds of staff. A trading company that brokers orders often reports a handful. A mismatch between a large claimed factory and a two-person payroll is a warning.
- Ask for the production licence and certificates in the factory's own name. Environmental permits, equipment certificates and product test reports should name the company you are paying. Reports issued to a different legal entity suggest you are buying from a middleman.
- Walk the floor on video or in person. Ask to see the machines that make your product, not a showroom. A real factory can show the line running, the moulds, the stock and the shipping area in one continuous clip. Editing, a fixed camera angle or a sudden cut are reasons to ask again.
- Match the paperwork to the goods. Ask which line will run your order, what the daily capacity is, and what the current lead time is. A trading company often answers with estimates. A factory answers with a schedule tied to real capacity.
| What you check | Factory | Trading company |
|---|---|---|
| Business scope | Production or manufacturing of the goods | Wholesale, retail, import and export |
| Insured staff | Often dozens or more | Often a small office team |
| Certificates | Issued to the company you pay | Issued to another company |
| Floor walk | Machines, moulds and stock on site | Showroom, or a partner factory |
| Lead time | Tied to real capacity | Estimated |
What the registry will not tell you
The registry is a starting point, not a verdict. A trading company can hold a manufacturing scope, and a factory can hold a trading scope for historical reasons. Records also lag behind reality. A licence can stay active after a line has stopped, and a company can register a scope it never uses.
Treat the registry as the first filter. It removes the obvious mismatches, and it gives you the legal name you should see on every certificate and quotation.
Where the floor matters most
For goods with tooling, tight tolerances or compliance requirements, the floor is where an order is won or lost. A sunglasses frame is a good example. The lens material, the coating and the mould all affect the test report, so the person quoting you needs control of the line. If they do not, the report can describe a lens the factory never makes.
If a supplier resists a live or recorded walk of the floor, ask why in plain terms. Most real factories are proud to show the line. Most middlemen change the subject.
When a trading company is the right choice
There are cases where a trading company earns its margin. It may consolidate several small items into one shipment, hold stock for fast delivery, or manage export documents and quality checks you do not want to run yourself. If you know you are buying through a middleman, you can price that margin into your costs and keep your expectations honest.
The mistake is not choosing a trading company. The mistake is choosing one while believing it is a factory, and paying for access you never get.
How this fits our own checks
We run these steps on every candidate before it reaches a report. Licence active and unflagged on the official registry, registered to manufacture, trading for at least two years, willing to let us film the floor, and no copies of other brands' designs. A factory that fails any of the five is dropped, and we tell you why.
If you would rather do the registry step yourself, our guide to checking a Chinese business licence on the official system walks through it. To see what a finished check looks like, read about eyewear sourcing in Danyang or see how the sourcing service works.
