How to Conduct a Product Quality Inspection in a China Factory

A step-by-step guide for importers and buyers.

How to Conduct a Product Inspection in China

The six decisions behind every professional inspection — written for buyers, not inspectors.

1

Define what "good" means, in writing

Inspections fail on vague specs, not on bad inspectors. Lock a golden sample, a written specification and a defect list before anything is booked — this becomes the checklist the factory and the inspector both work from.

2

Pick the checkpoint that matches your risk

New factory? Audit it before the first PO. Complex product? Check during production (10–50% complete). Standard order? A final random inspection when 80%+ is packed. Tight schedule or mixed containers? Add loading supervision.

3

Set your AQL before the visit

Most consumer goods run Critical 0 / Major 2.5 / Minor 4.0 under ANSI/ASQ Z1.4. Tighter limits mean bigger samples and higher cost — agree the plan in writing so the verdict cannot be argued afterwards.

4

Book 2–3 days ahead with a fixed fee

Send the PO, spec and factory city; confirm the man-day rate and report language up front. Book the inspection for when at least 80% of the order is finished and packed — earlier results do not represent the shipment.

5

Make sure sampling stays random

The inspector — not the factory — selects which cartons are opened, drawing from packed stock across the lot. If a factory offers a prepared "showroom" area, that is your cue to look closer.

6

Decide on the report, not on promises

Within 24 hours you should hold a photo-documented verdict: Ship, Hold or Rework. Release the balance payment only against that report — and if it is a Hold, ask for a corrective-action plan before re-inspection.
