Supplier due diligence
Factory vs trading company: how to tell the difference
When you ask a supplier where your goods are made, everyone says yes. The directory listing says “manufacturer”, the email signature says “factory direct”, and sometimes it is even true. Buying from an intermediary without knowing it means paying a margin you did not budget for, losing sight of who controls quality, and discovering in a dispute that the company you contracted has no machines to fix anything with. None of this makes trading companies bad — they exist because they are useful. The problem is not knowing which one you have.
There is no single test. There are seven checks, and together they give a picture no listing page will give you.
1. Read the business scope, not the name
A company register entry lists what the business is licensed to do. A manufacturer's scope names the making of goods — processing, production, manufacture. A trading company's scope reads like a shopping list: wholesale, retail, import and export of everything. The name alone proves nothing: many intermediaries call themselves "Industry Co., Ltd." and some genuine factories trade on the side. The scope on the licence is the first document to read, and a claim about manufacturing should point at it.
2. Match the registered address to the work
A factory needs land, sheds and machines, so its registration usually sits in an industrial zone or an industrial park. A company registered on an upper floor of an office tower in a city centre can still buy and resell for you — but the address is a hint, not a verdict. Some factories register a sales office downtown and keep the plant in a nearby county, so treat a mismatch as a question to ask, not an answer in itself.
3. Compare staff count with the order
Registries and trade platforms often show how many people a company employs. A workshop that claims to make your goods in volume but reports a handful of employees is telling you something. The same logic runs the other way: an enormous headcount with no factory floor behind it can mean a large trading house. The number only means something next to the product and the volume you are asking about — which is why a shortlist should show the figure, its source and its date.
4. Look at the width of the catalogue
Real production lines are specific. A plant that makes injection-moulded closures does not also forge steel valves, weave textiles and assemble electronics. A supplier offering thirty unrelated categories is almost always aggregating other factories' output. Depth in one narrow category is the strongest simple signal that you are looking at the machine that makes the thing.
5. Check whose name the certificates carry
A certificate for a management system or a product test lists the organisation it was issued to. If the name on the certificate is not the name of the company you are about to pay — or if the supplier shows a certificate but never shows whose it is — the claim has not been verified. Ask for the certificate with the licence number visible, then check it against the registry entry you already read.
6. Ask what happens on the day of production
Ask a direct, plain question: will my goods be made on your line, or will you buy them from another factory? A factory answers in specifics — which line, which town, when a visit is possible. An intermediary answers in reassurance. Neither answer is dishonest by itself; intermediaries can be useful. What matters is that you know which one you are talking to before you compare prices, because the two are carrying different costs.
7. Follow the export paperwork
Customs and trade records can show who has actually shipped a product category, under which company name, at what scale. A factory that exports directly appears as the shipper or exporter of record. A trading company appears instead, and the real maker stays invisible. Where such records are accessible to you, they are among the few sources that show behaviour over time rather than a self-written profile.
When the evidence disagrees
Real files are messy. A factory's licence may be out of date, a certificate may name a sister company, an address may have moved. The honest outcome of these checks is often not “factory” or “trading company” but “one source says this, nothing found to confirm that”. Write down which claims rest on the supplier's own words and which rest on an independent record, and treat the first kind as unverified until something supports them.
How ProcuraAI runs these checks for you
ProcuraAI researches permitted public sources and supplier websites and returns a shortlist where every claim carries its source URL, its evidence date and a state: verified, partially verified or unverified. It calls a supplier a manufacturer only when the evidence supports it — when the record is ambiguous, the label says so. You can see a sample shortlist built this way, for a product like the ones you buy.
ProcuraAI is run end to end by AI agents on NanoCorp, which is how a one-person team can keep guides like this one grounded in the same rules the product follows.
