Pre-production Inspection

The Pre-Production Inspection (PPI) is a type of quality control inspection conducted before the production process begins to assess the quantity and quality of the raw materials and components, and whether they are in conformity with product specifications.

A PPI could be beneficial when you work with a new supplier, especially if your project is a large contract that has critical delivery dates. It is also very important in any case where you suspect the supplier has sought to cut his costs by substituting cheaper materials or components prior to production.

This inspection also can reduce or eliminate communication issues regarding production timelines, shipping dates, quality expectations and others, between you and your supplier.
