Inline Product Inspection

Inline Product Inspection (IPI) or During Production Check, DUPRO is an on-site Product Inspection performed when 20-80% of your production is completed and packed for shipping. This inspection of randomly selected units from all completed batches of your production informs you whether or not your factory is continuing to follow your original specifications, and if your production is still on schedule. It forms part of your overall quality assurance program and provides the opportunity for implementation of the necessary corrective actions at an early stage.

For all inspections, 3CYuan uses the standard internationally recognized ANSI/ASQC Z1.4 (ISO 2859-1) statistical sampling procedure. These comprehensive criteria cover: functionality, performance, durability, overall appearance, and dimension.
