What is a Pre-Production Inspection?
A Pre-Production Inspection (PPI) is a quality control checkpoint performed before mass production begins. It verifies that raw materials, components, sub-assemblies and the production plan are correctly prepared, so the order is set up right from day one. PPI is one of the four standard inspection checkpoints used by importers and third party QC firms (alongside IPC, DPI and PSI).
What a PPI covers
- Raw materials - type, grade, quantity and conformity to the bill of materials
- Components and sub-assemblies - supplier, lot, condition and conformity to approved samples
- Production tooling, jigs, fixtures and machine calibration status
- Workshop readiness - capacity, line layout, workforce and shift plan
- Production schedule and milestones versus your delivery date
- Initial incoming-quality controls and traceability plan
When to book a PPI
Book a Pre-Production Inspection as soon as raw materials and components have arrived at the factory, ideally before more than 10% of production has started. PPI is especially valuable for new products, new suppliers, complex specifications or large-volume orders.
Why a PPI matters
- Catches wrong materials or wrong components before they are built into thousands of units
- Confirms the factory is genuinely ready to produce at scale
- Reduces rework, scrap and avoidable cost increases downstream
- Protects your delivery date by surfacing bottlenecks early
