You can usually tell within one video call. A factory can show you its SMT line, name the firmware engineers who will work on your project, and explain why a design decision was made. A trading company can show you a showroom and a catalogue, but has to “check with the factory” before answering technical questions.

This guide lists seven checks that separate a real manufacturer from a trading company, and explains when each one is actually the better choice for your project.

China Factory vs Trading Company: How to Tell Who You’re Buying From

Is a trading company automatically bad?

No. A good trading company can be the right partner if you are buying standard products, consolidating several categories into one shipment, or ordering volumes too small for a factory to prioritise. They often handle smaller MOQs, mixed containers and paperwork efficiently.

The problem is not the business model — it is **not knowing which one you are dealing with**. That matters most when something goes wrong: a firmware bug, a certification question, or a tooling change. A factory fixes these in-house; a trading company has to relay the question, and every relay costs days.

Seven checks

1. Ask for a live video walkthrough of the production line

Not a pre-recorded tour — a live call, walking from the SMT line through assembly, testing and packing. Ask them to show a machine running your product family. Factories do this without hesitation; intermediaries make excuses about schedules.

2. Ask who owns the firmware

This is the single most revealing question. If they cannot change firmware behaviour, provisioning flow, or app behaviour, they are reselling someone else’s platform. If they can describe the SDK, the module and the OTA update process, there are engineers behind the product.

3. Check the business licence

Ask for the Chinese business licence (营业执照) and look at the business scope. A manufacturer’s scope includes manufacturing or production (制造/生产); a trading company’s scope covers wholesale and retail (批发/零售) and often import/export. Also check that the registered address matches the factory address you were given.

4. Ask who is the applicant on the certificates

Test reports and certificates name an applicant company. If that company is not the supplier you are talking to, ask why. There are legitimate reasons (a group structure, or a subcontracted line), but you should hear a clear explanation.

5. Ask who owns the tooling

If you are paying for moulds, get it in writing that the tooling belongs to you, is marked as such, and can be transferred. A trading company may not be able to give you that undertaking, because the mould sits in a factory they do not control.

6. Ask about R&D headcount, specifically

Not “do you have engineers” but how many firmware engineers, hardware engineers and structural designers are in-house, and what they worked on most recently. Vague answers indicate there is no engineering team.

7. Look at the bank account name

The entity receiving your deposit should be the same entity you contracted with. A mismatch — especially a personal account — is a serious warning sign regardless of what the supplier calls itself.

Questions that expose the gap fastest

Which platforms have you actually shipped — Tuya, Zigbee 3.0, Thread, Matter — and can you give shipped model numbers?
What happens if we need a firmware change after the first shipment? Who does it and how long does it take?
Can I see the PCBA being assembled for my product family?
Who signs the firmware updates, and where are they hosted?
If we double volume next year, does your capacity come from your own lines or from subcontractors?

What a factory-direct relationship gives you

Working direct with the manufacturer means faster engineering changes, direct access to test reports, control over tooling, and a realistic answer when you ask whether something is feasible. It also usually means a lower unit cost at volume, because there is no intermediary margin.

Xingliao Technology is a Shenzhen-based manufacturer of smart switches, video doorbells, pet feeders and sensors, with 172 production-ready platforms across 16 product categories, in-house OEM and ODM engineering, and certification support for CE, FCC, RoHS, UKCA, CCC and PSE. Prototypes are delivered in 7–15 days and tooling in 25–40 days.

Frequently Asked Questions

How can I tell if a supplier is a factory or a trading company?

Ask for a live video walkthrough of the production line, ask who owns the firmware, and check the business scope on the Chinese business licence. Manufacturers have manufacturing in their registered scope and can show equipment running your product family.

Are trading companies more expensive?

Usually, but not always. They add margin, yet they may secure better prices through volume across factories. The bigger cost is time: every technical question has to be relayed, which slows engineering changes and problem resolution.

Can a trading company provide certifications?

They can pass on certificates, but check who the applicant is and whether the model number matches your product. You want the report for the exact model you are buying, issued to an entity that stands behind it.

Should I visit the factory?

If the order is significant, yes, or send a third-party auditor. If you cannot travel, a live video walkthrough plus a third-party pre-shipment inspection covers most of the risk.

Does factory-direct always mean lower MOQ?

Not necessarily, but it usually means more flexibility to negotiate a pilot run, because the factory controls its own schedule. On our lines, standard models start from 500 pcs per colour and full tooling projects typically run 3,000–5,000 pcs.
