Stay on Track: How a During Production Inspection (DUPRO) Ensures Quality Consistency
Your initial samples were perfect, and production is underway. But as the factory ramps up to full capacity, a critical question arises: Is the quality of the 1,000th unit the same as the first? Without on-site verification, you’re operating on trust alone. This is where a During Production Inspection (DUPRO) becomes an indispensable tool for supply chain management.
At Vietnam Inspections, we see DUPRO not just as an inspection, but as a real-time health check for your production run, offering you vital insights and control when it matters most.
What is a During Production Inspection (DUPRO)?
A During Production Inspection, also known as DUPRO or In-Process Inspection, is conducted on-site when 20-60% of your total order quantity has been manufactured. Our inspectors evaluate the semi-finished and finished products coming off the line, comparing them against your specifications and approved samples.
Crucially, a DUPRO also assesses the factory’s ongoing processes, allowing us to catch any deviations or quality fade before they affect the majority of your order.

The Strategic Benefits of a DUPRO: Your Mid-Production Safeguard
Skipping a mid-production check is a risk that can lead to costly delays and quality issues. A DUPRO provides essential benefits:
- Ensure Quality Consistency: A DUPRO is the ultimate test of uniformity. It verifies that the quality standards established at the beginning of the run are being maintained consistently across the entire batch.
- Real-Time Course Correction: If our inspectors identify defects or process deviations, they can be addressed with the factory management immediately. This allows for instant corrections, preventing the same mistake from being repeated on the remaining 80% of your products.
- Monitor Production Timeline: Are you on track to meet your shipping deadline? A DUPRO provides a clear, unbiased assessment of the actual production progress, giving you an early warning of any potential delays.
- Gain Crucial Visibility: For businesses managing production from thousands of miles away, a DUPRO offers invaluable peace of mind. It replaces uncertainty with a clear, on-the-ground picture of your operations, empowering you to make informed decisions.
