During Production Inspection (DuPRO or DPI), or inline Inspection is a pivotal quality control measure implemented when 20-80% of the manufacturing process is complete. At this juncture, the production line has reached a level of stability, and any defects detected are likely to be replicated across the batch. Identifying these defects early is a strategic move to mitigate extensive product loss. The sooner a widespread issue is discovered, the lower the cost and effort required for rectification.
In the 20-80% production phase, inspectors examine of semi-finished products at critical manufacturing stages. This ensures that any potential defects are caught before they become systemic. They also assess whether production is adhering to the projected timeline, which is crucial for meeting delivery deadlines. Whenever possible, they also evaluate the finished products for their craftsmanship, functionality, performance, and compliance with testing standards.
During Production Inspection is a proactive inspection approach. It is not just about defect control; it’s a forward-thinking strategy that underscores the commitment to excellence and reliability in production. By integrating inline inspection into the manufacturing timeline, buyers can make sure that the final products align with the high standards expected by consumers and uphold the integrity of the brand.
The importance of conducting a during production inspection (DuPRO) are summarized as below:
Identifying non-conformities during the critical stages of production is akin to an early warning system. During Production Inspection allows businesses to address issues promptly and devise a strategic plan for shipment. This proactive approach is crucial for mitigating risks and ensuring that the production schedule remains on track.
For eCommerce sellers, timing is everything. During Production Inspection provides a real-time snapshot of the production timeline, enabling sellers to confirm that their products will be ready for the promised delivery dates. It is a vital step in guaranteeing customer satisfaction and maintaining a competitive edge in the fast-paced online marketplace.
During Production Inspection fosters a collaborative environment between buyers and manufacturers. It shifts the focus from a high-stakes, pass-or-fail scenario, typical of Pre-Shipment Inspection (PSI), to a more constructive and less adversarial process. By involving manufacturers early and often, DuPRO encourages open communication and a shared commitment to quality, reducing the temptation for unethical practices.
When a supplier is open to DPI, it’s a strong indicator that they have direct control over the production line. This transparency can alleviate concerns about potential misrepresentation, ensuring that the supplier is not merely a middleman but has a genuine stake in the manufacturing process.

During Production Inspection is not just a checkpoint; it’s a strategic partnership tool that aligns the interests of buyers and manufacturers. It underscores a commitment to excellence and builds trust through transparency. By integrating DuPRO into the production process, businesses can enhance product quality, streamline operations, and foster stronger, more ethical supplier relationships.
Let’s break down the steps of During Production Inspection:
Strategic Planning: DPI isn’t a fly-by-the-seat-of-your-pants operation. It requires meticulous planning to nail down the when, where, and how of the inspection. This includes setting up clear communication channels with the factory to ensure everyone’s on the same page.
Opening brief: Upon arrival at the factory, the inspector should hold a briefing to outline the day’s objectives. This is also the time to remind the factory about the compliance hotline – it’s the red button they can hit if anything goes south with the inspector’s conduct.
Production Line Recon: The inspector needs to do a walkthrough, pinpointing the critical stages of production. Checking the workers’ instructions and production records gives a comprehensive view of the factory’s playbook.
Semi-Product Check: Inspector will pick the semi-finished goods at crucial checkpoints and put them through the wringer with necessary tests.
Schedule Verification: The inspector checks the production schedule against the plan. If things aren’t syncing up, it’s time to call an audible and adjust. It’s crucial for ensuring that the final whistle blows on time for shipment.
Final Product Sampling and checking: The inspector should also grab samples of the finished product at various time points to form a representative sample size.
Document Everything: All findings, photos, and videos should be meticulously recorded. The factory needs to sign off on these – it’s their acknowledgment of the inspection results.
Addressing Nonconformities: If any issues pop up, inspector will discuss with the factory for corrective and preventive actions. Documenting these steps is key – it helps to track for improvement.
Reporting: Compile all the documented findings into a comprehensive report for the clients.

Timing is everything. Ask your supplier for the production schedule, and book the inspection once 20 to 80% of the goods are made, ideally when the first finished pieces come off the line. That’s when the inspector can still catch a problem before it’s repeated across the whole order.
A during production inspection also checks whether the factory is on schedule, which protects your delivery date and builds a more open working relationship with your supplier.
