Quality Control in China: Inspections

A practical guide to quality control when sourcing from China — inspections at the right moments and defect handling.

Quality is managed, not hoped for

Quality problems in China sourcing are rarely random. They come from unclear specifications, unverified suppliers, and inspections that happen too late. Quality control is a sequence of checks placed at the right moments.

The inspection sequence

  • Pre-production: confirm materials, tooling, and packaging specifications before production starts
  • In-line inspection: sample products during production, when problems are still cheap to fix
  • Pre-shipment inspection (PSI): the final check — quantity, quality, packaging, and labeling before goods leave the factory

What a good PSI checks

  • Quantity matches the order
  • Quality meets the agreed brief — materials, finish, dimensions, function
  • Packaging and labeling are correct for shipping and your market
  • Documentation is complete for customs clearance

Handling defects

  • Define the defect standard in writing before production — "acceptable quality level" in the contract, not after the fact
  • Inspect before shipment so defects are caught while the supplier can still fix them
  • If defects arrive at your door, document them and manage the claim with evidence
