When you source from China, you're often paying more than you think — not to the factory, but to a middleman between you and the factory. Trading companies present themselves as manufacturers, use professional product photos taken at real factories, and quote prices that look competitive. But their margin (typically 15–30%) comes out of your pocket. Here's how to tell the difference.
Why It Matters
Factories control production, can customize products, offer lower MOQs on their own lines, and can troubleshoot quality problems directly. Trading companies add a markup, have less control over quality, and often can't give you real OEM options. Knowing which you're dealing with changes your negotiation strategy entirely.
When something goes wrong with an order — a defect, a delay, a spec mismatch — a factory can act on it immediately. A trading company has to relay the problem to the factory through their own relationship, adding time, miscommunication risk, and often a diminished sense of urgency since the financial pain is on your side, not theirs.
Clue 1 — The Company Name
Chinese company names reveal a lot. A name containing 贸易 (màoyì = trade) or 商贸 (shāngmào = commercial trade) is almost certainly a trading company. A name with 制造 (zhìzào = manufacturing), 实业 (shíyè = industry), or 科技 (kējì = technology) plus a factory product category is more likely a manufacturer.
This isn't definitive, but it's a quick first filter. Ask the supplier to share their business license and read the company name carefully. You can verify the full name on China's company registration system at gsxt.samr.gov.cn.
Clue 2 — Product Range Breadth
A real LED headlight factory makes LED headlights — maybe a few closely related products, but that's it. If a supplier on Alibaba sells LED lights, car seats, steering wheel covers, and phone holders, they are almost certainly a trading company buying from multiple factories and reselling to you.
Genuine manufacturers have deep but narrow product ranges. They've built machines, molds, and expertise for a specific product category. If the catalog looks like a department store, it's a trader's catalog, not a factory's.
Clue 3 — Willingness to Show the Factory
Ask directly: "Can I see the production line for my specific product on a live video call?" A factory will say yes and schedule it. A trading company will say "our factory partner doesn't allow visits" or send you a generic factory video that doesn't show your product being made.
Push further: ask to see the raw materials arriving, the intermediate assembly stages, and the quality control area. A factory has all of these and can walk you through them. A trader has none of them and will deflect.
Clue 4 — Pricing Patterns
Trading companies often quote a price that's suspiciously close to or slightly higher than a factory's price — because they need a margin but also need to seem competitive. If you receive three quotes and one is notably lower than the others, that supplier might actually be a factory. If one is oddly in between, it might be a trader undercutting the next trader.
Ask for a breakdown: raw material cost, labor, packaging, and factory margin. A factory can answer this with real numbers. A trader will give vague round numbers because they don't actually know the production cost — only the wholesale price they pay.
Clue 5 — The Address on Documents
Ask for a copy of the business license. The "registered address" should match a physical factory location, not a shared office building in the commercial center of Shenzhen or Shanghai. Use Google Maps Street View on the address — does it look like a factory compound or an office park?
Industrial zones in Guangdong typically have compound walls, loading docks, and row buildings with skylights. Office parks have lobbies, parking lots, and floor directories. The difference is usually visible from satellite view.
Clue 6 — Customization and MOQ Flexibility
Real factories can adjust molds, packaging, colors, and labeling because they own the machines. Trading companies have to ask their factory partner, which takes time, introduces errors, and limits your options. If a supplier says "all customization is possible" but then goes silent for three days every time you ask for a sample adjustment, they're not in control of production.
Test this early: ask for a small, specific customization — a logo on the packaging, a specific color variant, a dimension change. Time how long it takes to get a real answer. A factory responds within hours. A trader disappears to negotiate with their supplier.
How to Confirm It for Certain
Short of visiting in person, the most reliable method is a third-party factory audit. An inspector goes to the address, verifies the production equipment actually exists, checks the business license, and confirms the supplier manufactures what they claim. Some auditors charge $200–$400 per factory visit — a fraction of the cost of one bad order placed with the wrong type of supplier.
