Quality Control, PPAP and Batch Testing in China

Consistent quality is what makes overseas manufacturing work. We set up and run quality control with your Chinese manufacturer, so problems are found at the factory, not after delivery.

Approve first: PPAP before volume orders.

Check every batch: before goods ship.

Stay secure: dual-sourcing and clear contracts.

Frequently asked questions

How do I control quality when manufacturing in China?

Agree a written quality plan with the factory, approve the production process before volume orders, and check batches before they ship. We set up and manage each of these steps.

What is PPAP?

The Production Part Approval Process is a structured way to confirm that a supplier’s production process can consistently make parts to your specification. It was developed in the automotive industry and is now used more widely.

Who carries out inspections before shipping?

Our team or a partner checks batches before goods leave the factory. Where specialist expertise is needed, we bring in a third-party inspection company.

Can you help with shipping and customs?

Yes. We advise on pricing, Incoterms and customs, and help organise logistics from the factory to the UK.
