DUPRO — 20–80% Completion Checkpoint
During-Production Inspection in India
Catch systemic workmanship, dimensional, colour and material-substitution defects mid-run — when rework is cheap and your shipment date is still safe. AQL 2.5, ISO 2859-1, 24-hour photo reports.
Book a DUPRO InspectionWhat we inspect during DUPRO
Production progress vs. plan
Verify 20–80% of the order is actually produced. Compare to the factory's shipment timeline and flag delay risk early.
First-off-line workmanship
Pull units straight off the line — inspect stitching, finishing, polishing, soldering, assembly quality against the approved golden sample.
AQL 2.5 sampling on WIP
ISO 2859-1 sample plan on work-in-progress. Catches systemic defects before they multiply across the full lot.
Dimensional & spec checks
Critical dimensions, weights, colour matching (Pantone / lab dip), material composition — caught before they're locked in.
Raw material & component verification
Are the trims, hardware, fabrics, PCBs being used the same ones approved at PPI? Substitution is a top-3 defect source in India.
Corrective action capture
Defects logged with root cause, photo evidence, and a written corrective-action plan agreed with factory management on-site.
Why DUPRO is the highest-leverage QC checkpoint
Catch defects at 30% — not 100%
Re-work on 30,000 units is 3× cheaper than re-work on the finished lot, and it doesn't push your shipment date.
Hold the factory accountable mid-run
DUPRO reports trigger contractual obligations to rework before invoicing the next milestone. Pure leverage.
Protect your delivery date
Most production-delay disputes start with quality issues found at PSI. DUPRO surfaces them 2–3 weeks earlier.
Reduce PSI failure rate by 60–80%
Buyers running DUPRO + PSI consistently report sub-5% PSI failure rates vs. 20–30% on PSI-only programmes.
DUPRO FAQs
What is during-production inspection (DUPRO)?
DUPRO is an on-site quality inspection conducted when 20–80% of the order has been produced. It uses AQL 2.5 sampling on work-in-progress to catch systemic workmanship, dimensional, colour-matching and material-substitution defects before they propagate across the full lot. DUPRO is the most leverage-rich checkpoint in any QC programme because defects can still be reworked without delaying shipment.
When in the production cycle should DUPRO happen?
Best practice is to schedule DUPRO when 20–50% of units are finished and the rest are mid-line. This gives the inspector finished units to AQL-sample plus visibility into the in-process work. For orders over 50,000 units or 60-day production windows, run two DUPRO visits (at ~30% and ~70%).
How is DUPRO different from pre-shipment inspection (PSI)?
PSI happens when production is 100% complete and 80%+ packed — defects found at PSI mean re-work, re-packing and shipment delay. DUPRO happens mid-run, when defects are still cheap to fix and the factory hasn't locked in packing. Most professional QC programmes run PPI + DUPRO + PSI as three checkpoints, not just PSI.
What does DUPRO cost in India?
$220–$280 per inspector per 8-hour man-day in Tier-1 hubs (Delhi NCR, Mumbai, Tirupur, Jaipur, Moradabad, Ludhiana, Bengaluru, Chennai). One man-day covers most orders up to 10,000 units. See our QC inspection cost page for the full 2026 pricing table.
Is DUPRO worth it for small orders (under 5,000 units)?
For first orders with a new factory — yes, always. For repeat orders with a trusted factory and an MOQ under 3,000 units, DUPRO can be replaced with an extended PSI. We help buyers right-size the QC programme based on factory history, product risk class and end-buyer requirements.
