​

Before your supplier starts manufacturing in China, a pre-production inspection (PPI) is performed. Inspectors will inspect the supplier's raw materials, components, and quantities, guaranteeing compliance. When dealing with new suppliers or resuming manufacturing, a pre-production is essential.

​

An inspection serves as an extra pair of eyes and ears for the buyer to make educated choices by providing impartial information about the supplier and their skills. A PPI inspector may spot faulty components or materials, as well as detect communication problems and flaws in the manufacturing process before it starts.

It may be too late or too costly to replace these components after they have been integrated into a finished product. As a result, a pre-production inspection may assist to prevent this situation.
