YIVAHUBHow to Verify a Chinese Supplier: Licenses, Audits and Red Flags
2026-10-04 · YIVAHUB Team
Verification is the cheapest hour in sourcing. Everything it costs, it costs before you send a deposit — and everything it prevents happens after. Here is the sequence we run, in the order that catches the most problems per hour spent.
1. The licence, read carefully. Every legal Chinese company has a business licence with a unified social credit code. Check four things: the registered scope actually covers your product; the registered capital is not trivial for the order size; the company has been in business for years rather than months; and the registered address matches where you believe the goods are made. Trading companies are legitimate — but if a company presents itself as a factory and the licence says trading, you are entitled to know.
2. The address test. Registered address and production address diverging is the single most common sign of a trading company or an intermediary. It is not automatically a problem: a trading company that knows the belt can be a better partner than a mediocre factory. It becomes a problem when nobody will tell you where the goods are actually made, because then nobody owns quality.
3. The visit. A factory that will not accept a buyer-side visit is telling you something. On the visit, look for the processes your product actually needs — not the showroom. Ask what is done in-house and what is subcontracted, and photograph the line that would run your order.
4. Capacity against the queue. Ask for monthly capacity and how much of it is currently committed. A supplier who is honest about a full order book is more useful than one who promises every date you ask for. Lead times are set by the queue, not by enthusiasm.
5. Certifications, by number. ISO 9001, BSCI, product safety files — ask for the certificate number and the issuing body, then verify it. A logo on a spec sheet proves nothing; a file number that traces to a database proves a lot. Note also whose name is on the certificate: it is frequently a different legal entity from the one quoting you.
6. References and export record. Which markets do they ship to, for how long, and can they name any customer who will take a call? Many suppliers will decline the call — but the markets and the years are still informative, especially if your market is not among them.
Five red flags that should stop an order. The licence does not cover the product. The factory cannot show the process. Certificates do not trace. Capacity is promised with no queue information. And the quote sits far below the belt's floor price with no explanation of what was removed — because something always was. Thinner plating, a lower steel grade, a cheaper cartridge, a lighter carton. You will find out which one at your own cost unless you specify and inspect it.
