During-Production Inspection (DPI) in China
CGF Inspection’s During Production Inspection (DPI), also known as DUPRO (During Production Check), is a critical quality control process conducted when 10%-50% of your order is completed. This proactive inspection identifies potential issues early in production, allowing time for corrections before mass production is finalized. By monitoring production progress and product quality at this stage, we help you avoid costly delays, minimize defective units, and ensure on-time shipment.

What is During Production Check (DUPRO)?
During Production Check (DUPRO) is an essential preventative measure conducted in the early to mid-stages of production. It helps identify and resolve quality issues before too many defective items are manufactured, minimizing costly rework and avoiding delays in the shipping schedule.
CGF Inspection performs on-site DUPRO inspections when 30% to 50% of production is completed, ensuring consistent quality throughout the manufacturing process. Our inspectors follow ANSI/ASQC Z1.4 (ISO 2859-1) AQL sampling standards and provide detailed reports based on predefined acceptable quality levels.
