How to tell a real factory from a trading company

Why it matters

A trading company is not a scam. It is a middleman that buys from factories and sells to you, and there are situations where that is exactly what you want. The problem is not paying a middleman. The problem is paying a middleman while believing you are dealing with the factory, because every decision you make after that is based on something untrue.

It changes three things. Price, because there is a margin in the chain you did not budget for. Control, because your feedback on a defect passes through someone else before it reaches the people operating the machines. And evidence, because when you need a technical file or a test report in your own name, a reseller has to go and ask for it, and sometimes cannot get it at all.

The tells that something is off

A very wide, unrelated product range is the clearest one. A supplier offering cups, LED lighting and office furniture from one site is not manufacturing all three. Real factories are narrow, because the machines are narrow.

Watch for a quoted minimum that is suspiciously low for a bespoke product. Factories set minimums from setup time and material runs, so a genuine OEM order has a floor. Someone offering a hundred units of a custom item is usually buying from stock or aggregating your order with somebody else's.

Other signals worth noticing: the company name and the bank account name do not match; the address is an office tower rather than an industrial park; nobody will do a live video walk of the production line; answers about tolerances or materials come back slowly and vaguely, because the person answering has to ask someone else.

None of these is proof on its own. Two or three together usually are.

How to verify in twenty minutes

Ask for the business licence. Every Chinese company has one, and it carries a unified social credit code plus a stated scope of business. The scope is the useful part: a manufacturer's licence names production activities, while a trading company's names wholesale and import-export. This is not a document you should have to negotiate for.

Then check it yourself. The National Enterprise Credit Information Publicity System at gsxt.gov.cn is the official public register, searchable by company name or by the unified social credit code. Confirm the company exists, that the name matches the licence exactly, and that the registered scope is what you were told. A supplier who sends a licence that does not match the register has answered your question.

If the goods need certification, ask who holds the test report. A factory usually holds its own reports in its own name. A trader will often send you a report belonging to a third company, which is a problem the moment you need documentation naming your supplier.

The video call test

Ask for a live video call from the production floor, unscheduled if you can, and ask them to walk from raw material to packing. Not a recorded tour, not a photo folder. Photographs are shared between companies routinely; a live walk is much harder to borrow.

What you are looking for is mundane: does the line actually make your kind of product, is there work in progress on it today, does the person holding the phone know what the machines are called. Ask them to show the section where your product would run and to point out where quality checks happen. Someone who works there answers instantly. Someone who does not will pan away.

Do the call before you pay a deposit, not after. It costs half an hour and it is the single most informative thing a first-time buyer can do.

When a trading company is the right answer

Sometimes it is. If you need six different product types in one container, a good trading company consolidates them, handles the suppliers you do not want to manage, and ships one shipment instead of six. If your volumes are below what a real factory will entertain, a trader can get you started at all. If you need someone who answers in fluent English at UK office hours, that capability usually sits with the trading side rather than the production side.

The test is not factory versus trader. It is whether you know which one you are dealing with, and whether the margin you are paying buys you something you actually want. A trader who is open about being a trader, and who earns their margin in consolidation and quality control, is a legitimate part of a supply chain.

What you should not accept is a company describing itself as a manufacturer when the register says otherwise. That is not a business model difference. That is the first thing they were willing to be untrue about.

What it means for your paperwork

This becomes concrete when your goods need compliance evidence. As the UK importer you have to be able to produce a technical file and a declaration of conformity, and if you are selling under your own brand those obligations are yours as manufacturer, not the factory's.

A factory can normally hand over the underlying documentation because it generated it. A reseller has to obtain it from whoever did, and their supplier may not agree, may have changed component sources since the report was issued, or may not exist any more. You find this out when a customer, a retailer or a trading standards officer asks, which is the worst possible moment.

So make documentation part of the supplier decision rather than a later request. Ask, before the order: who holds the test reports, in whose name, covering which exact configuration, and will you give me a copy for my file?
