A third-party pre-shipment inspection in China typically costs USD 100–300 per man-day and checks your actual order — quantity, workmanship, function, packaging — against your specification before the balance payment is released. For most orders above a few thousand dollars, it is the cheapest insurance available.
- Standard service: one inspector, one day, one factory — commonly USD 100–300 all-in.
- Inspection happens when goods are at least 80% produced and packed, before you pay the balance.
- AQL sampling means a statistically valid sample is checked, not every piece.
- The report (photos, defect counts, measurements) reaches you within 24 hours — you then approve shipment or demand rework.
- Tie the balance payment to a passed inspection in your proforma invoice; that clause changes supplier behaviour.
What an inspection actually covers
- Quantity: cartons counted against the packing list.
- Workmanship: a random sample checked for visual defects, classified critical/major/minor.
- Function and safety: products powered on, assembled, load-tested as applicable.
- Conformity: materials, colours, logos, labels and barcodes against your approved specification or golden sample.
- Packaging: export carton strength, inner packing, shipping marks — the thing that decides whether goods survive Mombasa road transit.
You receive a photographic report the same or next day with a pass/fail against the agreed standard. The decision to release payment stays yours.
AQL in plain English
Inspectors use AQL (Acceptance Quality Limit) sampling: for a given order size, a defined sample is drawn (for example, 200 pieces from a 5,000-piece order at General Level II), and the lot passes if defects stay under thresholds — commonly 0 critical, 2.5% major, 4% minor for consumer goods.
This is the same statistical language big retailers use, which has a useful side effect: quoting 'AQL 2.5/4.0, Level II' in your order tells the factory you know what you are doing.
When to inspect — and when to skip
| Order profile | Recommendation |
|---|---|
| First order with a new supplier | Always inspect — this is where surprises live |
| Repeat order, stable product, good history | Spot-check every 2nd–3rd shipment |
| High-value or safety-critical goods (electrical, kids' products) | Inspect every shipment; consider during-production check too |
| Tiny trial order (< USD 1,000) | Inspection can cost 20% of the order; rely on photos/video instead |
How this connects to your payment flow
The classic 30/70 structure — 30% deposit to start production, 70% balance before shipment — has one weak point: once the 70% is paid, your leverage is gone. Slotting the inspection between production and balance payment fixes the sequence: inspect, pass, then release the balance in RMB through your documented payment channel.
If the inspection fails, you negotiate rework or discount while you still hold the money. That conversation goes very differently after payment.
One more habit worth building: file every inspection report alongside the golden-sample photos, the proforma invoice and the payment record for that order. Six months later, when a customer complaint or a customs query surfaces, that single folder answers in five minutes what would otherwise take a week of chasing WeChat history — and it is exactly the evidence set that wins supplier disputes.
Frequently asked questions
Who are the main inspection companies?
International firms (SGS, TÜV, Intertek, QIMA) and many capable regional agencies operate across Guangdong, Zhejiang and beyond. For standard consumer goods, well-reviewed regional firms at USD 100–200 are usually sufficient.
My supplier says their own QC is enough. Is it?
Factory QC works for the factory. A third party works for you. Polite insistence on independent inspection is normal professional practice in China and no serious factory is offended by it.
Can the inspector be bribed?
It happens, which is why you use firms with rotation policies and audit trails, give precise specifications, and cross-check reports against the golden sample photos you hold.
