Quality Control When Importing from China

Updated May 18, 2026

One bad batch can sink your reviews and your margin. Quality control is how you catch problems in China — before they reach your customer.

The inspection stages

Quality isn’t a single check at the end; it runs through production:

  • Pre-production inspection — verify materials and components before manufacturing starts.
  • During-production inspection — monitor the run to catch defects early.
  • Post-production inspection — final verification of finished goods against your spec.
  • Loading supervision — oversee packing and loading to prevent transit damage.

Add laboratory testing for anything with safety or compliance requirements.

What inspection actually catches

Wrong materials, off-spec dimensions, finish and assembly defects, mislabeled or short quantities, and packaging that won’t survive transit. These are cheap to fix in the factory and expensive to discover after shipping.

Factory audits

For a long-term supplier or a regulated product, a factory audit checks the manufacturer’s capability and systems — not just the sample. Worth it before committing to volume. (Pair this with vetting the supplier.)

When to inspect

For most orders, a pre-shipment inspection on a finished batch is the highest-leverage check. For new suppliers, larger orders or regulated goods, add earlier stages.

This is built into how we work — see quality control, part of the wider sourcing process.
