How to Conduct DUPRO and PSI Inspections for Products from China

DUPRO (During Production Inspection) and PSI (Pre-Shipment Inspection) are the two primary quality control checkpoints for goods manufactured in China. Elite Global Trade Ltd manages both inspection types for B2B importers, providing independent photo and video reports before any shipment is released.

What is a DUPRO Inspection?

A DUPRO inspection takes place during production — typically when 20–40% of the order has been completed — to identify quality issues while there is still time to correct them.

A DUPRO by Elite Global Trade covers:

• Materials verification — raw materials match approved specification and Golden Sample
• In-process quality checks — workmanship, assembly, dimensions and tolerances
• Production line assessment — worker skill, equipment condition and process control
• Early defect identification — classified as critical, major or minor per AQL standard
• Corrective action request — written CAR issued to factory if defects exceed AQL threshold

What is a PSI Inspection?

A Pre-Shipment Inspection takes place when 100% of production is complete and at least 80% is packed and ready for loading.

A PSI by Elite Global Trade covers:

• AQL sampling — random sample drawn per ISO 2859-1
• Workmanship and appearance — defect classification at AQL 2.5/4.0
• Functional testing — operation, performance and safety checks
• Packaging and labelling — carton markings, barcodes and presentation
• Quantity verification — physical count against PO
• Loading supervision — optional container stuffing with photo record

AQL Standards Used by Elite Global Trade

• AQL 1.0 — critical defects (safety, regulatory, total non-function)
• AQL 2.5 — major defects (likely to cause customer rejection)
• AQL 4.0 — minor defects (cosmetic, unlikely to affect function)

Custom AQL levels available on request for safety-critical products.
