Red Flags When Sourcing from China: 8 Critical Warning Signs

Every importer we talk to has a story about the order that went wrong, a deposit wired to a supplier who vanished, or goods that arrived nothing like the samples. The red flags when sourcing from China are rarely a mystery in hindsight. They were visible the whole time. Here’s what to watch for before you commit, not after.

The Red Flags When Sourcing From China That Matter Most

1. No business registration number. Every legitimate Chinese company has an 18-digit registration number. If a supplier won’t share it, or gives a number that doesn’t match their invoice, stop there.
2. Mobile number only, no landline. Real factories have a fixed business line. A supplier who only ever answers on a personal mobile is easier to disappear.
3. The “business scope” doesn’t say manufacturing. A factory’s registered business scope includes words like “manufacture” or “produce.” If it doesn’t, you may be dealing with a trading company posing as a factory.
4. Photos that don’t match the address. Stock factory photos, or photos with visible signage from a different company, are a common shortcut for shell operations.
5. Residential or shared office address. Real manufacturers operate from industrial zones. A residential registration address is a serious warning sign.
6. Pressure to pay 100% upfront. Standard terms are a partial deposit to start production and the balance before shipment. A demand for full payment upfront is one of the clearest signals to walk away.
7. Refusal to allow inspection. A legitimate factory has nothing to hide from a pre-shipment quality check. Reluctance here is rarely innocent.
8. Price that’s too good against everyone else’s quote. An outlier-low quote is sometimes just an aggressive factory, but it’s also the oldest bait in the book.

What to Do If You Spot These Red Flags

One red flag doesn’t automatically mean a scam, but it means slow down. Ask directly for the documents in question, verify them independently rather than trusting a photo sent over chat, and treat a supplier’s reaction as information in itself. A legitimate factory answers these questions without hesitation. Anyone who deflects, stalls, or gets defensive is telling you something.

Vendor due-diligence frameworks used well outside of China sourcing, JPMorgan’s guide to vetting suppliers covers the same fundamentals: verify registration, check references, and never treat a refusal to share basic documentation as a minor detail.

How We Actually Verify a Factory Before Recommending It

Every supplier we work with goes through the same process before a client ever hears their name: we confirm the business registration number directly, not from a photo sent over chat. We visit the physical address and confirm it matches an actual production facility, not a residential unit or a shared office. We ask to see the production floor, not just a showroom. And we check whether the factory has a landline tied to their registered business, since a mobile-only contact remains one of the simplest tells that a supplier isn’t set up the way they claim to be.

None of this is exotic due diligence, it’s the same handful of checks covered in almost any vendor-vetting framework. The difference is that we do it in person, on the ground, before a client’s money is ever at risk, rather than relying on documents a supplier chooses to send.

Every factory we work with has already been walked through this exact checklist by our own team, in person, before we ever recommend them to a client. That’s the entire point of having boots on the ground in Yiwu, the red flags when sourcing from China are a lot easier to catch when someone is physically standing in the factory, not reading a business license photo over chat.
