Costly sourcing mistakes and how to avoid them
The mistakes that cost importers the most money — and the specific step that prevents each one.
Most sourcing losses are not bad luck — they are the same handful of avoidable mistakes, repeated. Here is our honest field list, with the check that prevents each one.
1. Paying 100% in advance to a new supplier
A new supplier has no reason to fix a problem once the money has cleared. Keep a meaningful balance payable against inspection or documents, and treat any insistence on full prepayment as a negotiating position, not a rule.
2. Assuming your supplier is the factory
Most listings you find online belong to trading companies. Ask for the business licence, the plant address and a live walk-through of the line running your product — and check the licence scope covers manufacturing, not just wholesale.
3. Skipping pre-shipment inspection
Inspection is the last point at which a problem is still the supplier's to fix. Agree an AQL level and a written checklist before production starts, and hold the balance payment until the report is accepted.
4. Ordering against vague specifications
"Same as the photo" is not a specification. Put material, grade, dimensions, tolerance, finish, packaging and labelling in writing, and make the purchase order refer to that document.

5. Not sealing an approved golden sample
Without a sealed, dated sample held by both sides there is nothing objective to judge bulk production against. Seal two: one with the factory, one with you.
6. Misunderstanding Incoterms and landed cost
An attractive FOB price can become an expensive delivery once freight, duty, clearance and local handling are added. Always compare quotations on landed cost at your door, in your currency.
7. Wiring to a changed bank account
Payment-diversion fraud usually arrives as a polite email saying the usual account is under audit. Verify any change by voice with a known contact, and confirm the account name matches the company on your contract.
8. Sharing designs without protection
Drawings and tooling shared without an agreement often reappear as a competing product. Use a bilingual NDA/NNN agreement, register your trademark in the country of manufacture, and split sensitive processes where you can.
9. Ignoring Chinese New Year timing
Factories slow down before the holiday, close for two to four weeks and restart with new staff. Place orders early, expect a quality dip in the pre-holiday rush, and plan inspection around the shutdown.

10. Depending on a single country or supplier
One tariff change, freight spike or capacity problem can stop your whole programme. Qualify a second source — ideally in another country — before you need it.
11. Working without a bilingual contract
A purchase order is not a contract. A bilingual agreement covering specification, inspection, delivery, payment, liability and jurisdiction is what makes the terms enforceable.
12. Chasing the cheapest quote
When a price is far below the market, something has been removed: material grade, process step, testing or service. Ask what changed rather than assuming you negotiated well.
