During Production Inspection · DPI / DUPRO

Inspect while production can still be corrected.

Independent checks at an agreed production milestone to identify deviations before the entire order is completed, packed or ready for final shipment inspection.

Why DPI

Find problems before they multiply across the whole order.

A during-production inspection is useful when production has started and enough material is available to evaluate, but corrective action may still be practical before final completion.

01

Production Status

Record finished, semi-finished, unfinished and packed quantities against the order and agreed milestone.

02

Early Product Conformity

Compare available production against drawings, specifications, approved samples and other client-defined requirements.

03

Workmanship

Identify visible defects, finishing concerns or recurring quality issues before they continue across the remaining production.

04

Dimensions & Material

Check selected dimensions and agreed material characteristics where suitable methods and references are available.

05

Packing Readiness

Review the packing status and whether packaging, labels or shipment marks are ready to be verified at that production stage.

06

Corrective-Action Visibility

Give the buyer documented evidence early enough to discuss correction, rework or production-control actions with the supplier.

Typical Use Cases

DPI is especially useful when early execution risk matters.

  • New supplier or new product.
    Check whether early production matches the agreed requirement before the full batch is completed.
  • Large orders.
    Identify systematic quality issues before they affect a much larger quantity.
  • Critical dimensions or finishing.
    Verify selected characteristics while process adjustments are still possible.
  • Tight delivery schedule.
    Create visibility on actual production progress and readiness before the final shipment window.

DPI vs PSI

Two checkpoints, different timing.

During Production Inspection

Performed at an agreed stage while production is still in progress. The objective is early visibility and corrective-action opportunity.

Pre-Shipment Inspection

Performed when the shipment is substantially ready and enough finished goods are available for the final agreed inspection scope.

Best practice: for higher-risk orders, a buyer can combine supplier qualification, during-production inspection and pre-shipment inspection rather than relying on a single final checkpoint.
Methodology

Production-stage findings need context.
