Written for global buyers and sourcing managers. Chinese factories reading this — the Chinese-language articles on this site are for you; this one looks through the buyer's eyes.
You found a supplier on Alibaba, made-in-china.com, or at a trade show. Price looks right. Photos look right. The salesperson replies fast in good English.
Then the shipment arrives late. Or quality does not match the sample. Or — worst case — you paid a deposit and the company disappeared.
In 12+ years bridging global buyers and Chinese factories, I have watched these same traps repeat. Here are the 17 that matter, in two stages: before you inquire and before you place the order.
Stage 1 — Before you even inquire
Trap 1 · Response speed — they are timing you
Buyers typically contact 5–10 suppliers at once. Whoever responds within 24 hours, professionally, moves to round two. After 48 hours of silence you are usually off the list — the supplier will not tell you; they simply stop replying.
Trap 2 · Email professionalism reveals the whole team
Check the email signature, greeting, grammar and layout. ALL-CAPS messages, no salutation, broken English — instant distrust. For a Chinese factory, the English email is the first face it shows the world.
Trap 3 · "We are a factory" — but the license says trading
Ask for the business license. The scope will state either "manufacturing / processing" or "sales / trading". If it says trading, you are dealing with a middleman: higher prices, less quality control, unverifiable delivery.
Trap 4 · Claimed headcount vs social-insurance headcount
A factory claiming 300 staff but insuring only 15 is almost certainly a middleman or tiny workshop. Cross-check on China's public business registry.
Trap 5 · Certificates that are real only in a photo
ISO9001, CE, FDA — anyone can put a logo on a slide. Demand the certificate number and issuing body, then verify on the issuer's portal (SGS, TÜV, BV). PS-edited certificates are common.
Trap 6 · The price that is too good
A quote 15–20% below the industry average always has a reason: substituted materials, cut processes, or hidden fees that surface after you commit.
Trap 7 · Vague MOQ
"MOQ is negotiable" is not an answer. If they cannot state a number, they have not planned how your order will actually be produced.
Trap 8 · Delivery in "days" — but which days?
30 days might mean 30 working days (≈42 calendar days). If you plan a launch around the wrong number, you miss your season. Demand working vs calendar days, and separate confirmation time from production time.
Stage 2 — Before you place the order
Trap 9 · Buyers talk to each other
The sourcing community is small. Buyers ask peers: "How is this factory?" One bad story travels faster than any brochure. Ask for 2–3 references you can actually call.
Trap 10 · Customs data does not lie
Professional buyers check real export records. Claim "we export to 20 countries" but customs shows a handful of shipments — the story collapses. Export records are the hardest proof of capability.
Trap 11 · Great sample, bad batch
The most common and costliest trap. A workshop can hand-craft one perfect sample but lacks standardized mass production. Verify the QC system: incoming-material checks, in-line inspection, final inspection, defect handling.
Trap 12 · No written QC standard
If they cannot hand you a written standard covering material, process, tolerances and defect thresholds — walk away. Without it you have no baseline for inspection or claims.
Trap 13 · Live video tour refused
A real factory can show its production line on a five-minute video call. Refusal is a red flag large enough to end the conversation.
Trap 14 · "Unlimited capacity, instant delivery"
Real factories quote realistic lead times from an actual schedule. Anyone promising the impossible is over-promising — and will outsource your order or slip the date.
Trap 15 · Payment terms that leave you unprotected
Never pay 100% in advance. Safe structure: 30% deposit + 70% against B/L copy, or an LC. Tie the final payment to an independent inspection report.
Trap 16 · No inspection before shipment
A few hundred dollars of third-party AQL inspection before shipment saves tens of thousands in defective goods. Treat it as non-negotiable on first orders.
Trap 17 · Nothing in writing
Verbal promises and WeChat chats are not a contract. Get it in writing: spec and tolerances, MOQ, delivery terms, Incoterms, QC standard, packing, and remedies for defects.
The bottom line
Reliable China sourcing is not about the cheapest quote. It is a repeatable process: verify the entity, confirm real capacity, lock QC standards in writing, stage payments, inspect before shipment.
Do these 17 checks and the traps largely disappear. Skip them, and you are gambling — not sourcing.
