In-Process Inspection Services
Pro QC International provides third-party In-Process Inspections (IPI/DUPRO) in 100 countries, helping businesses detect defects early and ensure product quality during production
Pro QC International provides third-party In-Process Inspection services (IPI), also called During Production Inspection (DUPRO), in 100 countries for a large variety of product categories.
Companies need transparency and visibility into the manufacture of their products and a reassurance that final product quality will meet their requirements. In-Process Inspection serves these goals. Conducted during the production process at the most critical steps, IPI provides essential information on actual manufacturing conditions and product quality.
What is an In-Process Inspection?

An In-Process Inspection is a product inspection conducted during the manufacturing process. This control is carried out at different stages and at predetermined times. The inspection usually occurs when at least 20% of the products are completed. It provides monitoring and assurance that the factory is following established production methodology and techniques. Conducting During Production Inspections helps to identify defects at an early stage and eliminate them before products are finished, which prevents additional costs downstream.

Pro QC’s In-Process Inspection Services
As a third-party quality company, Pro QC supports companies across the globe in providing impartial During Production Inspection services. Our experienced quality inspectors conduct each inspection. Inspectors are selected according to their industry experience, as knowing the manufacturing processes specific to the products to be inspected is paramount. For instance, a textile inspector will be deployed for a garment in-process inspection while a mechanical engineer will conduct a motorcycle in-process inspection.
During the service, the inspector will walk through the selected processes and follow a comprehensive inspection checklist to ensure product quality matches the specifications. Through this step-by-step process, inspectors will identify and correct any anomaly or quality defect quickly. Customers are immediately informed if there are any major or critical problems.
