Quick Answer
A during-production inspection (DUPRO) is conducted when roughly 10–40% of an order is produced. It samples finished units from the line and checks them against specification, allowing problems to be corrected while production continues — before the whole order is affected.
When DUPRO Is Most Valuable
DUPRO is most valuable for large orders, ongoing production, and products where defects can emerge partway through a run. By catching issues at 10–40% completion, corrections can be applied to the remaining production rather than discovering problems only at the end.
- Conducted at ~10–40% of production
- Samples finished units against the spec
- Allows correction while production continues
- Best for large or continuous runs
Key Takeaways
- DUPRO inspects at 10–40% of production.
- It allows correction during the run.
- Best for large or continuous orders.
- Bridges pre-production and pre-shipment checks.
Frequently Asked Questions
What is a DUPRO inspection?
A during-production (DUPRO) inspection is conducted when about 10–40% of an order is produced. It samples finished units against the specification so problems can be corrected while production continues.
When should I use a DUPRO inspection?
Use DUPRO for large orders, continuous production, or products prone to defects partway through a run, so issues are caught early enough to fix the remaining production.
How is DUPRO different from pre-shipment inspection?
DUPRO happens during production and allows mid-run correction; pre-shipment inspection happens after production is complete and checks the finished order before it ships.
Do I need DUPRO if I already do pre-shipment inspection?
For large or higher-risk orders, DUPRO adds value by catching problems early enough to correct, whereas a failed pre-shipment inspection can mean reworking the entire order.
Can Plutonia run a DUPRO inspection?
Yes. Plutonia conducts during-production inspections at the agreed stage and reports findings so issues can be corrected before the run completes. Submit your order details to start.
