*China supplier scams cost importers an average of $19,400 per incident. Here are the 12 patterns we keep catching — and the 10-minute check that filters out ~70% of frauds before a dollar moves.*

Every supplier scam on Alibaba, Made-in-China and Global Sources is one of four moves:
fake identity, fake factory, fake certification, or bait-and-switch.
Once you know which of the four you're looking at, the defense is mechanical.
A perfect sample. Then production goods arrive 15–40% cheaper in materials.
In our inspection log, 23% of first-time orders showed material deviation from the approved sample; 6% failed buyer QA on arrival.
Defense: sealed retained sample, signed by both parties *before* production, physically checked against the production run at the pre-shipment stage.
An attacker intercepts the email thread, sends a "corrected" wire instruction from a near-identical domain (`1xchina-factory.com` vs `lxchina-factory.com`). The deposit goes to the attacker.
Defense: voice-confirm any bank change on a known phone number before wiring. Always.
Stock footage and competitor video assembled into a "factory walkthrough" sent on WhatsApp. The factory does not exist.
Defense: insist on a live, unscripted video call with a visible time-and-date overlay. Real factories say yes in minutes.
A PDF showing certification on a product. The certificate number is invalid, expired, or belongs to a different product. Customs holds the shipment at port.
Defense: verify every certificate through the issuing body's public database. Takes under 5 minutes per certificate.
We ran a registered-capital check on a "factory" a buyer was about to wire $38,000 to.
The company had cut its registered capital by ¥6.44 million (644万) and its headcount was down 88% year-over-year — a company in active retreat presenting itself as a growing manufacturer. The buyer walked.
Defense: check registered capital history and headcount trend (社保参保人数), not just "years in business."
A supplier claimed a second factory branch to win a large order. The branch registration didn't exist in the official registry.
One query, 90 seconds, order saved.
Defense: every claimed address → official registry lookup (国家企业信用信息公示系统 / GSXT). Match legal name, address, and the bank beneficiary exactly.
Rents a desk in an industrial park, says "we are factory direct."
Tell: can't answer machine model numbers, raw material grades, or production cycle times in specifics.
Defense: ask three technical questions only an engineer on the floor can answer. A real factory replies in minutes; a costume replies in vague copy.
Physics still applies in China. Cheap has a cost — either the product is counterfeit/substandard, or the money never becomes goods.
Defense: if one quote is 30%+ below the other three, that's not a deal, that's a flag.
"Special price valid only today." "Only 3 units left."
Real factories rarely operate with theatrical scarcity.
Defense: anything that rushes you off the platform and into a wire is a scam. Full stop.
They refuse Trade Assurance / platform escrow and push Western Union, personal bank account, or crypto.
Defense: platform escrow is your single strongest protection. Bypassing it removes all recourse. Never wire to a personal account.
The contact email is @gmail or @163.com. Real companies have company domains (even small ones).
Defense: check the domain's WHOIS and match it to the registered company.
Reverse-image-search product and factory photos. Scammers lift images from other listings — mismatched backgrounds between "factory" and "products" reveal the theft.
Defense: reverse image search takes 30 seconds per photo.

1. Open the business license PDF, confirm the name matches the bank-transfer beneficiary. *(90 seconds)*
2. Pull the WHOIS record for their email domain. *(60 seconds)*
3. Search the Unified Social Credit Code on the national registry. *(90 seconds)*
4. Check registered capital history + headcount trend (社保). *(2 minutes)*
5. Reverse-image-search their factory and product photos. *(60 seconds)*
6. Ask three technical questions a real engineer answers in minutes. *(wait time)*
This pass rules out roughly 70% of pure-fraud operators before a single dollar moves.
