During Production Inspection



What is During Production Inspection (DUPRO) or in process quality control?

DUPRO quality inspection is the process of checking prepared and packaged products that are ready to be shipped. It takes place in the Chinese factory once the production process has begun but before it is completed.


What do we look for during DUPRO?

We work to ensure that your order meets your expectations for appearance or Acceptance Quality Limit (AQL), workmanship, size, weight, functionality, appendages, artwork, packaging, packing, and any other special requirements pertaining to the product or its destination or from your specific quality control checklist. DUPRO also includes provisions for raw materials, unfinished products, and production planning.

Benefits of DUPRO:

DUPRO gives you the ability to interface with an already ongoing production process, introduce responsive measures, and take pulse of your quality control expectations. Not to mention forecasting an on-schedule production cycle. We accomplish this by examining actual production volume to foresee any delays of your shipment inspection. This foresight allows you to step in during the production process and make any necessary changes while remaining on-schedule. Control the quality of your Chinese supplier during production of you order.


●    Mirroring golden sample quality with the rest of your production items.

●    Diagnose production issues to prevent excess defective items.

●    Snapshot of adherence to AQL.

●    Comprehensive investigation of the production process:

●    Stop cost overruns and production delays.

  • " Just the mention of GuangdongInspection got me instant results. When I told my factory representative in China that I was sending in a team from GuangdongInspection, the agent hesitated and then reluctantly admitted that there was no factory, despite pictures of a busy factory on their website. Lesson learned, I never start production without sending GuangdongInspection in first. "
