During Production Inspection (DUPRO)
Catch defects at 20–80% production — when there’s still time to fix them. In-line quality checks that protect your entire order.
What Is a DUPRO Inspection?
A During Production Inspection (DUPRO), also called an In-Line Inspection, is conducted when 20–80% of your production is complete. Unlike a pre-shipment inspection, DUPRO allows defects to be identified and corrected while production is still underway — preventing a full batch of defective goods.
DUPRO is especially valuable for large orders, new factories, or high-risk products where catching problems late would be costly or impossible to remedy.
What DUPRO Catches
- Systematic production errors affecting multiple units
- Material or component substitutions mid-production
- Workmanship issues: poor stitching, incorrect assembly, surface defects
- Colour or material deviations from approved samples
- Incorrect sizing, measurements, or specifications
- Machine calibration and production process issues
When to Order DUPRO
- Orders over 3,000 units or high-value shipments
- New factory relationships (first 1–3 orders)
- Products with complex assembly or tight tolerances
- When your supplier has a history of last-minute surprises
- Combined with a pre-shipment inspection for full coverage
DUPRO vs Pre-Shipment: Which Do You Need?
DUPRO (In-Line)
- Conducted at 20–80% production
- Defects can still be corrected
- Best for large/complex orders
- Prevents systematic failures
Pre-Shipment (PSI)
- Conducted at 80–100% production
- Final quality gate before shipping
- Best for all orders
- Approves or rejects shipment
