What do the actual scam mechanics look like, not just the warnings?

None of the mechanics below are exotic — they recur across the China-sourcing niche generally, and naming exactly how each one works is more useful than a vague warning to “be careful.”

The deposit-and-disappear

A buyer wires a deposit against an order, often to a personal bank account rather than a verified company account, and either the goods never ship, ship as something clearly different from what was ordered, or the supplier goes silent after the payment clears. The mechanic depends on the deposit being sent before the buyer has done enough verification to know whether the counterparty is real — the dedicated payment-safety page covers how to structure a deposit to reduce this exposure.

The sample-swap

A supplier provides a genuinely high-quality sample to win the order, then ships a bulk order made to a lower spec — cheaper materials, looser tolerances, a shortcut in construction that doesn’t show up until the goods arrive. This works because a sample and a bulk production run aren’t automatically held to the same standard unless a buyer specifically arranges inspection against the sample before shipment, which is exactly what an independent, non-conflicted inspection exists to catch.

The factory that isn’t

A booth or showroom presents production capability that doesn’t actually exist behind it — a trading company implying factory-direct pricing and control it doesn’t have. The dedicated page on this specific mechanic covers the checks that catch it.

The guaranteed-visa or pay-for-invitation scheme

An intermediary offers to “guarantee” a visa outcome, or charges a fee specifically for obtaining a Canton Fair badge or invitation letter — both of which the organiser issues directly and free of charge. This isn’t a hypothetical concern: an official embassy notice aimed at Canton Fair buyers has directly warned against intermediaries promising a guaranteed visa or a “no visa, no payment” arrangement, exactly the kind of promise this mechanic relies on.

No legitimate party can guarantee a visa outcome, since that decision sits with the consulate, not with any intermediary — an offer that implies otherwise is the tell, not the reassurance it’s meant to sound like.

Inspection collusion

A supplier arranges or influences who performs your “independent” inspection, so a report comes back clean regardless of what’s actually in the shipment. This is the sharper edge of the conflict of interest covered on the inspection-versus-agent page — the fix is the same one: an inspector with no relationship to either the supplier or your sourcing agent, paid by you specifically.

The upfront-fee sourcing scam

An “agent” collects a fee for sourcing services before doing any verifiable work, then delivers little or nothing — a poor supplier match, no real vetting, or simply going quiet after payment. This is different from a legitimate flat fee, which is tied to a defined scope of work; the tell here is a payment requested with no clear deliverable attached to it.

What actually reduces your exposure across all of these

Verification before payment, payment structured so leverage doesn’t disappear the moment money moves, and independence between whoever finds your supplier and whoever checks the resulting goods. None of these mechanics survive a buyer who insists on all three.
