How do I spot a trading company disguised as a factory?
Short Answer: Five Behavioural Tests, Not a Licence Check
Disguised traders refuse factory visits, cannot answer technical questions, span ten unrelated product categories, demand all money flow through their own account, and will not provide the original factory invoice. Real factories let you pay the maker directly and welcome a third-party audit.
The Pattern That Hides Behind a Polished Listing
The most common 'factory' a new importer meets on Alibaba is in fact a small trading company with a glossy catalogue, an English sales engineer and a domain they registered last year. The trading company is a perfectly legal business. The problem is only the label. Once a supplier claims to be the manufacturer, every signal they send is filtered through the buyer's expectations of a factory - capabilities, control, accountability - and the trading company has incentives that quietly diverge from those expectations.
Five behavioural tests separate the two. None of them require Chinese language or an in-person visit. All of them work from the buyer's first email to the buyer's first PO.

Five Tests for a Real Factory
Why the Five Tests Stack
Each test removes one form of deception. The five together remove most of them. A real factory that wants your order will pass all five because the answers are routine to them. A trading company will fail at least two, because the answers expose the structural fact they would rather keep quiet.
The cheapest test in the set is the third: 'Can I pay the factory and pay you a separate fee?' A real factory says yes. A disguised trader says no.

Case: The Catalogue That Spanned Eleven Categories
A buyer was sourcing a simple kitchen tool and found a supplier on Alibaba with a clean business licence, a 6-year trading history and a catalogue covering silicone tools, glassware, electric kettles, yoga mats, pet toys, stationery and seven more categories. The buyer asked one process question: at what temperature and for how long is the silicone cured?
The supplier replied with a marketing paragraph that did not contain a single number. The buyer asked for a live video walk of the silicone line. The supplier offered a pre-recorded clip. The buyer asked whether payment could go directly to the factory. The supplier insisted that all payments had to be handled by the export department for tax efficiency.
We confirmed within an afternoon that the supplier was a Yiwu trading company without a workshop of its own.
The Three Things Genuine Factories Let You Do
If you have never worked with a Chinese factory before, the list of things a real factory agrees to can feel surprisingly open. They are not concessions. They are baseline expectations of any well-run manufacturer.
Walk the floor on a video call with the salesperson naming the machines. Pay the factory bank account, not the trading company's. Send your own inspector on a date the agent does not know in advance. Ask for the factory's own invoice and compare the unit cost with the trading company's commercial invoice. None of this is adversarial. All of it is how the relationship is supposed to work.

How to Use the Five Tests When the First Quote Looks Good
The first quote is usually the most favourable. Use it as a starting point for the five tests rather than as a signal to commit. A supplier who reacts well to the five tests is statistically likely to be a real factory. A supplier who reacts badly to two of the five is statistically likely to be a trader.
The most useful moment to run the tests is after you have a quotation but before you have sent a deposit. The tests lose half their value if you have already paid.
How RND SOURCING Differentiates the Two
We work in Yiwu, where the trading-company share of the market is closer to 70% than to 10%. Knowing which kind you are talking to is therefore a routine part of our work, not a special investigation.
We disclose the supplier type in writing at the start of the relationship. If the right counterparty is a trading company - and for small mixed orders it often is - we say so. If the right counterparty is a factory, we give the factory name, the address and the live video walk on request.
The five tests are not our tests. They are the buyer's tests. We simply help the buyer run them.
