Pre-Production Inspection (PPI) is an inspection conducted at the early stage of foreign trade order execution, before mass production begins, covering raw materials, components, production process readiness, and first article samples. Its core purpose is to control quality from the source and avoid mass rework caused by material or process defects. Use cases include: high customer quality requirements, large order amounts, or first-time cooperation with a supplier. Notes: PPI should be conducted after raw materials are received and before the production line starts, and the inspection scope should cover key materials and first articles; if problems are found, they must be rectified before mass production. Compared with During Production Inspection (DUPRO) and Pre-Shipment Inspection (PSI), PPI focuses more on prevention rather than process control or final gatekeeping. PPI cannot replace DUPRO and PSI; the three are often used in combination to form a complete quality control chain.
📝 Examples
1. We recommend arranging a Pre-Production Inspection before mass production to confirm that all raw materials and first article samples meet contract specifications. (Note: Raise the PPI requirement with the supplier at the early stage of the order to prevent mass quality risks.)
2. According to the PPI report, the fabric used by the supplier was underweight, so we required them to replace the material before starting mass production. (Note: After PPI identifies material issues, promptly require rectification to avoid subsequent losses.)
