How to Choose a Supplier When Buying a Machine in China? Run These 7 Checks First
- ✓Decide what you are really buying: factory or trading company
- ✓Verify the company can legally export — and pay only the company
- ✓Ask for a live factory video with today's date
Most buyers choose a machine supplier in China the same way: send the same message to ten companies on Alibaba, take the fastest answer and the lowest number. That is exactly how people end up paying a trader's price for a factory machine, or a factory price for a machine that was quietly re-specified. In the Zhengzhou belt alone we watch the same machine leave three different kinds of seller — the factory that builds it, the trading company that resells it, and the "agent" who owns nothing at all.
So how do you choose a supplier when buying a machine in China? Work through the seven checks below before you discuss price. Each one is something you can ask for on WhatsApp today, and each one is a place where a weak supplier will stall, change the subject or simply stop replying. If you want the deeper version of any single step, we cover them in How to Find a Sourcing Agent in China and the 7-Point Inspection Checklist.
1. Decide what you are really buying: factory or trading company
Open the business licence and read the registered scope: a manufacturer lists production and a real workshop address, a trading company lists trade and an office. A trading company is not automatically a scam — but its price, its warranty and its after-sales chain are a different product. Know which one you are paying before you compare numbers.
2. Verify the company can legally export — and pay only the company
Ask for the business licence with its unified social credit code, the import-export right, and the customs registration record. The beneficiary name on the invoice must match that licence exactly. If the supplier wants a personal bank account, a friend's company or a third currency account, stop — a legitimate exporter is paid to the company account.
3. Ask for a live factory video with today's date
A polished showroom clip proves nothing; it can be years old and shot anywhere. Ask for a live video call walking the actual production line, showing the exact machine you are buying together with its serial number, with the date visible in the frame. A real factory can always film itself; a rented address cannot.
4. Compare quotations line by line, never by total price
Two quotes 20% apart are rarely the same machine. Put them on one table: model, power, capacity, weight, motor and gearbox brand, steel thickness, control panel — and what is excluded, such as freight, installation and spare parts. Compare identical specifications first, and only then compare the number at the bottom.
5. Check who really makes the core components
Ask for nameplate photos of the motor, gearbox, bearings and hydraulic parts, then compare them against the brochure you were sent. On the same model, a premium motor and a budget motor can differ by thousands of dollars. This is where a suspiciously low quotation quietly comes from.
6. Ask for real customers and a spare-parts list
A supplier who has genuinely exported to your region can give you two or three buyers to contact, and a dealer who stocks wear parts. Ask for the wear-part price list and the delivery time for a spare motor before you pay. Machines never fail politely — the spare-parts chain decides your real cost of ownership.
7. Lock price, payment and delivery into one written contract
The contract should state the exact specification, packing, delivery time, port of loading, Incoterm, warranty terms and the payment schedule — typically 30% deposit, balance against the bill of lading copy. Never pay 100% in advance, and never to a personal account, however friendly the negotiation has been.
The price rule we apply to every supplier quotation
A genuine factory quotation and a trader's quotation for the same machine can differ by 15–30%, so never judge a supplier by its total number. Normalise every offer to the same specification, then compare. A price far below the factory level is not a bargain — it is the first sign that steel, motor or components were changed. We quote you the factory price and show the evidence: a factory visit with a live video of your exact machine is USD 100 per supplier.
