How to Tell if a Chinese Supplier Is a Factory or Trading Company

When sourcing machinery from China, one of the first questions you should ask is: Am I dealing with a factory or a trading company? Both can sell you equipment, but the difference affects pricing, quality control, after-sales support, and your ability to resolve problems. Many trading companies present themselves as manufacturers, and the distinction is not always obvious from a website or an Alibaba listing.

This guide explains how to tell the difference, why it matters for machinery buyers, and what you can do to confirm.

What Is a Trading Company?

A trading company (贸易公司) is a business that buys products from factories and resells them to overseas buyers. They do not manufacture the equipment themselves. Their role is to source products, handle export documentation, and act as an intermediary between you and the actual factory.

Trading companies are not inherently bad. For small orders or when you need a variety of products from different factories, a trading company can be helpful — they consolidate sourcing, handle logistics, and manage communication. But for machinery purchases, where specifications are complex and after-sales support is critical, buying through a trading company adds layers of risk:

Higher prices. The trading company marks up the factory price, sometimes by 10–30%.
Less technical knowledge. Trading company sales staff may not deeply understand the machinery they sell. They often cannot answer detailed technical questions or customize specifications.
No direct factory access. If something goes wrong with the equipment, the trading company must coordinate with the factory on your behalf, which can lead to delays and finger-pointing.
Quality control gaps. The trading company does not control the production process. They inspect goods after production, if at all.

Signs of a Real Factory

How do you know if you are dealing with an actual manufacturer? Look for these indicators:

Business scope includes manufacturing. The business license (营业执照) lists the company's registered business scope (经营范围). If it includes "生产" (production/manufacturing) or "制造" (manufacturing), the company is licensed to produce goods. If the scope only lists "销售" (sales) or "进出口贸易" (import/export trade), it is a trading company.

Technical staff and engineering capabilities. A real factory has engineers, technicians, and a production manager. When you ask technical questions — about motor brands, material specifications, control systems, or customization — a factory can give you detailed, specific answers. A trading company may give vague responses or need to "check with the factory."

Factory photos with consistency. Ask for factory photos. A real factory's photos will show consistent branding (company name on the building, on workers' uniforms, on equipment). The photos should show production areas with machinery, raw materials, and work-in-progress. Be wary of photos that look like stock images or show different company names on different photos.

Willingness to arrange a factory visit or video call. A genuine manufacturer will usually agree to a factory tour or a live video walkthrough. They have nothing to hide. If the supplier resists, offers to "show you the showroom instead," or only provides pre-recorded videos, they may be a trading company using someone else's factory.

Detailed knowledge of the production process. Ask the supplier to describe how the machine is made: What materials do they use? What is the production lead time and why? What quality checks do they perform during production? A factory representative can answer these questions in detail. A trading company representative often cannot.

Signs of a Trading Company

Now look for the opposite side — indicators that the supplier is a trading company posing as a factory:

Broad product range. If a supplier claims to manufacture everything from food processing equipment to construction machinery to packaging lines, they are almost certainly a trading company. Real factories specialize in a product category. No single factory makes 50 unrelated types of machinery.

"Gold Supplier" but no verified factory. On Alibaba, a "Gold Supplier" badge means the company paid for a premium membership — it does not mean they are a factory. Look for the "Verified" type: Alibaba distinguishes between "Trading Company," "Manufacturer," and "Trading Company, Manufacturer" (meaning both). But even this label is self-reported and should be independently confirmed.

Business scope shows trade only. As mentioned above, if the business license scope does not include manufacturing terms, the company is legally registered as a trading company — regardless of what their website says.

No in-house engineering. If you ask for a customization (e.g., a different motor brand, a modified production capacity, or a non-standard voltage), and the supplier says "let me check with our engineers" but never follows up with a technical answer, they are likely relaying your request to a separate factory.

Pricing that seems too high. Trading companies add a markup. If you receive quotes from multiple suppliers and one is significantly higher than the others for the same specifications, they may be a trading company reselling another factory's product.

Questions to Ask the Supplier

Here are specific questions you can ask to determine whether you are dealing with a factory or a trading company:

Can you send me a copy of your business license? (Check the business scope for manufacturing terms.)
Are you a manufacturer or a trading company? (Some will honestly tell you. Some will lie. Use this as one data point, not the final answer.)
Can you arrange a video call to show me the production floor? (A factory will usually say yes. A trading company may deflect.)
What is your factory's address? Can I see it on Google Maps? (Cross-check against the business license address.)
How many workers do you have, and what is your monthly production capacity? (A factory can give you specific numbers. A trading company may give round numbers or say "it depends.")
Can you customize the machine to our specifications? What changes can you make? (A factory will discuss specific technical modifications. A trading company may say "yes we can" without technical details.)
Who handles after-sales support if something breaks? Do you have technicians, or do you contact the factory? (This reveals whether they have in-house technical capability.)
Can you provide photos of the factory with your company name visible? (Look for consistency with the business license name.)

Why It Matters for Machinery Buyers

For consumer goods — phone cases, T-shirts, promotional items — whether you buy from a factory or a trading company matters less. The products are simple, the order values are low, and quality issues are relatively easy to resolve.

For machinery, the stakes are different:

Customization is common. Machinery buyers often need specific configurations — different voltage, different production capacity, specific material for food-grade compliance. A factory can engineer these changes. A trading company cannot — they must ask the factory, and communication layers introduce errors.
After-sales support is critical. When a machine breaks down, you need spare parts, technical guidance, and sometimes a technician. A factory has the technical staff and spare parts inventory to support you. A trading company must relay your request to the factory, adding delays.
Quality control during production. A factory controls the production process from raw materials to final assembly. If you want to inspect the machine during production or request specific quality checks, the factory can accommodate. A trading company has no control over the production floor.
Price transparency. When you buy from a factory, you get the factory price. When you buy from a trading company, you pay their markup — and you may not know how much margin they are adding.

How to Confirm

The most reliable way to confirm whether a supplier is a factory or a trading company is to combine multiple verification methods:

Check the business license. The business scope is the most definitive indicator. If it does not mention manufacturing, they are a trading company.
Search the company on Chinese business databases. Use the National Enterprise Credit Information Publicity System (gsxt.gov.cn) to verify the registration details.
Request a video call. Seeing the production floor in real time is hard to fake.
Ask technical questions. Gauge whether the representative has deep product knowledge or is just relaying messages.
Check the Alibaba or Made-in-China profile. Look at the company type, years on platform, and whether they have been audited by a third-party inspection agency (SGS, TUV, Intertek).

If you are about to place a significant order ($10,000+), consider hiring a third-party inspection company to visit the factory and verify its operations. This costs $300–$500 but can save you far more if the "factory" turns out to be a small office.

Conclusion

Factory or trading company — it is one of the most important distinctions when sourcing machinery from China. Trading companies are not always a bad choice, but you should know which one you are dealing with, because it affects pricing, quality, customization, and after-sales support.
