Inline Inspection (DUPRO)
Catch manufacturing defects early when only 10-30% of goods are finished. Don't wait until it's too late to fix them.
What is Inline Inspection?
Also known as During Production Inspection (DUPRO), this service takes place when your production is between 10% and 30% complete. Unlike pre-shipment inspections that happen at the end, DUPRO allows us to check the first finished units coming off the line.
We verify that the factory is following your specifications, using the correct raw materials, and that the initial output meets quality standards. It acts as a crucial checkpoint to correct manufacturing processes before mass production continues.
- Verify production schedule and capacity
- Identify systematic defects in early stages
- Ensure raw materials match approved samples
Why Early Defect Detection Matters
Waiting until the end is expensive. Catching issues early saves your budget and timeline.
Without Inline Inspection
You discover 20% of your products have a wrong logo placement during the final Pre-Shipment Inspection.
With Inline Inspection
We find the logo placement issue when only 500 units are made.

"We caught a wrong component issue when only 200 units were soldered."
Client: Audio Equipment Brand (USA)
Problem: The factory used a cheaper capacitor than specified in the BOM (Bill of Materials) for the first batch.
Action: REPA's inspector identified the mismatched component during DUPRO at 15% completion.
Result: Factory stopped production, sourced the correct capacitor, and reworked the initial 200 units. Delay: 2 days. Without DUPRO, the entire batch would have been defective upon arrival.
Frequently Asked Questions
When is the best time to book an Inline Inspection?
Ideally, you should book this service when 10% to 30% of the goods are completed. This is the "sweet spot" where we can check finished quality but still have time to correct production processes for the remaining 70%+.
What is the difference between DUPRO and Pre-Shipment Inspection (PSI)?
DUPRO happens during production to fix issues early. PSI happens after 100% production is done to verify final quality before loading. DUPRO is for corrective action; PSI is for final validation.
Is Inline Inspection suitable for all products?
It is highly recommended for complex products (electronics, machinery), large quantity orders, orders with new suppliers, or time-sensitive shipments where you cannot afford a rework delay at the end.
