During Production Inspections (DUPRO)
What Is During Production Inspection?
A During Production Inspection (DUPRO) also called In-Process Inspection, IPQC, or Inline Quality Inspection is performed when 20–80% of an order is complete. Instead of waiting until production finishes, we inspect while goods are still being made, catching problems when they’re fast and affordable to fix.
QCI.Asia provides DUPRO inspection services across Vietnam, China, Thailand, and the Philippines, following AQL (Acceptable Quality Limit) standards with structured defect classification.

When You Need DUPRO Inspection
Key scenarios for mid-production inspection:
- Timeline pressure – Tight deadlines where you can’t afford to find problems at final inspection
- Production issues emerging – Factory reports quality problems and you need to assess the scope
- Complex assembly processes – Multi-step products where early defects compound through the entire process
