Inspection Services for Contract Manufacturing

A quality inspection company can provide various inspection services. There are 4 types of inspection services that are particularly relevant to contract manufacturing in China.

In factory audit, the inspection company sends a professional inspector to visit the target factory in person. He will assess the physical environment, production capacity, technological capability, quality control system, human and corporate organization, licensing, certifications etc. The inspector will issue detailed audit report to verify the claims of the factory and to reflect any issues and problems.

2) Initial Production Check (IPC)

In the initial production check, the inspector checks if the raw materials and components for the production are correct and in good quality. He needs to check the production and quality control procedures are set up correctly. The IPC identifies any quality issues at the very beginning of the production so that correction measures are implemented early.

3)  During Production Check (DUPRO)

During production check also called receiving inspection, it aims to identify and eliminate quality issues from the production line when at least 25 % of finished product are produced. It enables the manufacturer to correct and improve the defects before the mass production.

4) Final Random Inspection (FRI)

Final random inspection or pre-shipment inspection is conducted when 100% of the production is completed and at least 80% of the products are packed in export cartons. This inspection is conducted using random sampling procedures based on international standard such as MIL-STD-105E, ANSI/ASQC Z1.4., etc. The inspection makes sure the product quality, product outlook, workmanship, packaging are confirmed with the specifications and requirements of the order.
