Every week someone messages me a screenshot of a disaster: a supplier who vanished after a 50% deposit, a container held hostage at a US port, a "CE-certified" product seized by customs. The depressing part is that almost none of these were sophisticated crimes. They were textbook scams with textbook warning signs, visible before any money moved.

Here are the seven I check for on every deal, in the order they usually appear — from first contact to final payment.

1. The "Too Good" Unit Price (Bait Pricing)

A quote 15%–30% under every other supplier isn't negotiation skill; it's bait. The pattern: win your deposit with the low price, then "discover" material cost increases, mold fees, or packaging charges before shipment — or simply ship lower-grade goods at the quoted spec.

The check: collect three to five quotes and treat the outlier as a warning, not a win. Real factories quote inside a fairly tight band because they're all buying the same materials.

2. The Trader Dressed as a Factory

A large share of "factories" on B2B platforms are trading companies with a rented showroom and borrowed photos. Traders aren't automatically bad — but you'll pay their margin on top, and when quality fails, they're a middleman relaying your complaints, not a production line fixing them.

The check: business license scope (production vs. sales), a video call from the production floor at a random time, and the five verification checks I use before any deposit. A real factory never hesitates to show its line; a trader invents excuses.

3. The Golden Sample Switch

The sample is perfect. The bulk order is... close, but the plastic is thinner, the print is off, the stitching is looser. This isn't always malicious — production drifts without supervision — but with a dishonest supplier it's deliberate: the sample comes from a better line or a better material lot.

The check: keep the approved sample sealed and photographed, write the spec into the contract with tolerances, and run a pre-shipment AQL inspection against that sealed sample before the balance payment. Inspection is the only point in the process where you still have leverage.

4. Paper Certifications (Bought, Not Earned)

CE, FCC, RoHS certificates are sold online for a few hundred dollars, complete with your product name. Customs doesn't care that you were fooled — the seizure is your loss, not the supplier's.

The check: verify every certificate on the issuing body's own database (not a link the supplier sends), and confirm the certificate holder's company name matches the factory's legal name exactly. Mismatched names are the most common tell.

5. The Off-Platform Payment Redirect

"Pay our Hong Kong account for a better price" or "our Alibaba account is under audit, use my manager's personal account." The moment money leaves the platform's trade-assurance wrapper, your recourse goes with it. Personal accounts and freshly opened HK shell accounts are where deposits die.

The check: the receiving account name must match the company on the business license, on the platform, and on the contract. All three. Any pressure to deviate — especially with a deadline attached ("the price is only valid today") — is the scam talking.

6. The Vanishing Forwarder (Double-Freight Trap)

You pay a freight forwarder in full. The forwarder issues a House Bill of Lading but never pays the ocean carrier. At destination, the carrier refuses to release the container until you pay the freight again. Your goods, held hostage, twice-paid.

The check: never pay freight 100% upfront to an unknown forwarder; verify the forwarder's license and how long they've traded; for FCL, confirm the Master Bill of Lading exists and the carrier is paid before release. A legitimate forwarder accepts payment terms because they'll be around next year.

7. The Fee-Stacking Quote (Death by Surcharges)

The freight quote that's impossibly cheap, then grows: fuel surcharge, security fee, origin handling, destination handling, "customs facilitation." By the time your cargo is loaded, switching costs more than paying. This is the freight version of bait pricing — and it's everywhere.

The check: demand an all-in door-to-door quote with every line item before booking. Here's what honest 2026 rates and surcharges actually look like — if a quote is far below the base-rate floor, the difference is coming for you later.

The Payment Structure That Defuses Most of These

None of the checks above require expertise — they require discipline. The single biggest risk reducer is payment structure:

  • 30% deposit, 70% balance only after a passed inspection. Anyone demanding 50%+ upfront on a first order is shifting all risk to you.
  • Balance released on inspection report, not on "goods are ready" photos. Photos show what the supplier wants you to see.
  • Everything in writing: spec sheet, tolerances, certifications required, inspection standard, payment account. WeChat voice messages are not a contract.

Scammers optimize for buyers who skip these steps because the steps are "slow." The steps are exactly the point.

The Rule

Trust is built with documents and verified in person — never with chat history. A supplier can be charming for three months and still ship garbage. The buyers who lose money aren't the ones who trusted the wrong person; they're the ones who trusted instead of verifying. Verification is cheap. A container of unsellable stock is not.
