To vet a Chinese supplier at a trade fair: confirm what they actually are (factory, trading company or middleman) by reading their business license, not their booth; treat too-good-to-be-true prices as warnings; order a paid sample and a pre-shipment inspection before you trust bulk quality; and never pay 100% up front — 30% deposit, 70% after inspection is the safe default. The booth is where you qualify a supplier, not where you close. Below is the floor-tested checklist, a red-flag table, and the scams that cost importers real money.
Factory vs trading company vs middleman — and why it matters
Three kinds of "supplier" stand behind the booths at the Canton Fair or in the aisles of Yiwu, and knowing which one you're talking to changes your price, your quality control and your risk.
- Factory (manufacturer). Makes the goods. Best price on its own product line, direct control over quality, but often narrow (one category) and weaker at export paperwork and English.
- Trading company. Buys from factories and resells to you. Wider catalogue, smoother communication and export handling — at a markup, and one step removed from the production line. Not inherently bad; a good trading company is worth its margin on a mixed order.
- Middleman / agent. An individual or tiny office reselling under a borrowed identity. This is where most outright fraud hides, because there is no real business behind the WeChat photo.
How to tell them apart
The single most reliable signal is the business scope (经营范围) on the company's official business license, which you can check for free on China's National Enterprise Credit Information Publicity System (GSXT) or via tianyancha.com. A factory's scope contains production words — 生产 (produce), 加工 (process), 制造 (manufacture); a trading company's leans on 批发 (wholesale) and 进出口 (import/export) (JingSourcing). Note the traps: many trading companies put "manufacturing" or "industrial" in their name purely for marketing — the name is just characters, the license is the source of truth. And the registered address is not automatically the factory address, nor is the legal representative automatically the owner (bo-asia).
Quick booth tells: ask a deep technical question about the production process. A factory rep answers from the floor; a reseller deflects to "our engineers." Ask for a 17% VAT invoice — real manufacturers issue them, and the company name on the invoice must match the license (ChineseCheck).
Verification checks: license, video tour, references
Do these before any money moves, even for a supplier you liked at the show.
- Get the license in Chinese, not just an English certificate, and read the name off it. Then verify that exact Chinese company name on GSXT or Tianyancha — registration date, capital, scope, legal representative. A company registered three months ago is not automatically a scam, but it changes how much you risk on order one.
- Ask for a live video tour at a random time during Chinese working hours (roughly 9:00–18:00 GMT+8). A genuine factory can walk you through the line on short notice; a middleman stalls (ChineseCheck).
- Match the bank account to the license. The beneficiary on the wire should be the company, in China, with a name matching the license — never a personal account, never Hong Kong for a mainland factory without explanation.
- Ask for references or trade records and, for anything meaningful, plan a third-party inspection or factory audit rather than trusting the tour alone.
Red flags at the booth
| Red flag | What it may mean | What to do |
|---|---|---|
| Price far below every other quote | Corners will be cut on materials/QC, or a low anchor to be clawed back later | Treat the cheapest quote with more suspicion than the dearest; ask what's different in the spec |
| "Yes, no problem" to every request | They've confirmed nothing; a real factory pushes back on unclear specs | Ask a question with a wrong assumption baked in — see if they correct you |
| Won't put price/MOQ/lead time in writing | No basis for a dispute later | Get a written quote (photo of the price card counts) before you leave |
| Refuses the license in Chinese, or only shows English | Possible reseller or forged identity | Insist on the Chinese license; verify the name yourself on GSXT/Tianyancha |
| Pushes you to "confirm today" / pay a deposit at the booth | Manufactured urgency; nothing closes at a booth | Say "I'll compare and come back this week" — a complete, respectful answer |
| Payment to a personal or mismatched account | Classic fraud vector | Only wire the company account that matches the license |
| Vague on samples, factory visits, inspection | Something to hide about real production | Make a paid sample and pre-shipment inspection non-negotiable |
MOQ = Minimum Order Quantity (smallest order accepted). T/T = telegraphic transfer (bank wire). B/L = bill of lading (the shipping document proving goods are loaded).
Samples and third-party inspection
A great sample proves the supplier can make it well once. It does not prove your bulk run will match — that's the gap bait-and-switch and quality fade live in (more below). Two habits close it:
- Pay for the sample. Order a real sample against your written spec, ideally a "golden sample" both sides sign off as the reference. Paying is normal and filters time-wasters; the cost is often credited against the first order.
- Book a pre-shipment inspection (PSI). An independent inspector from a reputable firm — QIMA, SGS, Bureau Veritas, Intertek — checks the finished goods against your spec and an agreed AQL (Acceptable Quality Limit, the defect threshold you'll tolerate) before you release the balance. Budget roughly $300–600 for a one-day on-site PSI (ChineseCheck). On the numbers, that is cheap insurance: reported China import scams averaged around $87,500 per fraudulent transaction in 2025 (ChineseCheck). See our guide to quality control and inspection in China for how to scope one.
Safe payment terms
How you pay is your strongest lever against fraud and quality problems, because it decides when the supplier gets your money.
| Method | When it fits | Watch-out |
|---|---|---|
| 30/70 T/T (30% deposit, 70% before shipment) | The default for most orders | "Before shipment" alone triggers your balance the moment goods are finished, defects or not — tie the 70% to inspection pass, not just completion (China Makers Hub) |
| Alibaba Trade Assurance / escrow | First orders under ~$20k with an unproven supplier | Only protects you if the full spec is written into the contract; funds release on agreed terms (ChineseCheck) |
| Letter of Credit (L/C) | Large orders, typically $50k+ | Bank fees run $500–1,500+ per side; overkill for small orders (ChineseCheck) |
| 100% up front | Almost never | A supplier who'll produce on 100% prepayment from a stranger is huge, a years-long partner — or a scam (ChineseCheck) |
The practical rule: pay the 30% deposit by T/T to the verified corporate account, and release the 70% after a passing pre-shipment inspection. If a supplier emails mid-order that their "bank account has changed," stop and call a known contact to confirm — a last-minute account switch is a well-worn fraud (ChineseCheck).
Common scams, and how each one breaks
- The reseller in factory's clothing. A trading company or agent poses as the manufacturer. Beaten by reading the business scope and asking for the VAT invoice.
- Ghost factory / forged license. No real production behind the photos, or a doctored certificate. Beaten by verifying the Chinese name on GSXT/Tianyancha and the random-time video tour.
- Bait-and-switch. An excellent sample, then a bulk run with cheaper materials or looser tolerances. Beaten by a signed golden sample plus a PSI tied to payment (Zignify).
- Quality fade. Quality drifts down over repeat orders as margins tighten, betting you won't notice until switching hurts. Beaten by inspecting every order, not just the first.
- Bank-account-change fraud. A mid-order email redirects your balance to a new account. Beaten by verifying any account change by phone with a known contact.
Capture what you need to vet, right at the booth
You can't vet 40 suppliers from memory two weeks later. The verification checklist only works if, at each booth, you leave with the company's exact Chinese name, the quote (unit price + currency + MOQ + tier breaks), the sample cost and lead time, and the contact — captured consistently, so you can compare the same product across suppliers and run the license/scope checks calmly afterward. Pair it with an interpreter or sourcing agent when a booth speaks no English and the license is only in Chinese.
FAQ
How do I tell a factory from a trading company at a booth?
Read the business license, not the booth. A factory's business scope (经营范围) contains production words — 生产, 加工, 制造 — while a trading company's leans on wholesale (批发) and import/export (进出口). Names mean nothing; many resellers put "manufacturing" in their name for marketing. Confirm by asking a deep process question and requesting a 17% VAT invoice whose name matches the license.
What payment terms are safe with a new Chinese supplier?
30/70 T/T is the default: 30% deposit to the verified corporate account, 70% balance before shipment — but tie that balance to a passing pre-shipment inspection, not just "goods finished." For first orders under ~$20k with an unproven supplier, Alibaba Trade Assurance or escrow adds protection if the spec is in the contract. Reserve letters of credit for orders above ~$50k. Never pay 100% up front.
Is a very low price a good sign at a trade fair?
No — it's usually the opposite. A quote far below every competing price signals cut corners on materials, labour or quality control, or a low anchor meant to win the deal before the spec is locked, with the gap recovered later through change orders or cheaper components. Treat the cheapest quote with more suspicion than the most expensive, and ask exactly what's different.
How much does a third-party inspection cost, and is it worth it?
A one-day, on-site pre-shipment inspection from a reputable firm (QIMA, SGS, Bureau Veritas, Intertek) typically runs about $300–600. Against reported China import scams averaging roughly $87,500 per fraudulent transaction, it's cheap insurance. Tie your final payment to a passing inspection against an agreed AQL, so defects are caught before your money leaves.
How do I verify a Chinese supplier's business license?
Get the license in Chinese (not just an English certificate), read the exact company name off it, and verify that name for free on China's GSXT system or on tianyancha.com — checking registration date, capital, business scope and legal representative. Then confirm the wire beneficiary is that same company, in China, and request a live video factory tour at a random time during Chinese working hours.
