What is a During Production Inspection China (DUPRO / DPI)?
A During Production Inspection (DUPRO) is a quality control check performed while production is ongoing, typically when 20% - 80% of the order is completed. It allows issues to be identified early and corrected before the full order is finished. Unlike inspections at the end of production, this inspection allows you to correct issues immediately, before they affect the entire order.
During the inspection, our specialists verify:
Product quality and workmanship
We check for defects, inconsistencies, and overall product quality during production.
Production status and progress
We verify production output, timelines, and whether manufacturing is on track according to your order.
Raw materials and components
We check materials and components used to ensure they meet your specifications and quality requirements.
Functionality and specifications
We test products and measure key parameters to confirm they meet your technical requirements.
Compliance with your specifications
We compare products against your requirements, drawings, or approved samples to ensure consistency.
