What is a during-production inspection (DUPRO)?

A during-production inspection (DUPRO) checks an order while it is being made, typically when 20–60% is complete. The inspector looks at finished units, work in progress and materials to find defects that would otherwise repeat across the whole order, and agrees corrective actions with the factory while most of the order can still be made right.

What a DUPRO looks at that a PSI cannot

A pre-shipment inspection sees only the finished product. A DUPRO sees how it is being made. That matters most for faults that hide inside the product or start early in the process:

  • Joinery and frames before upholstery or finish covers them.
  • Wood moisture content before finishing locks it in.
  • Fabric weight and shade on cut panels before sewing.
  • Materials in the store against the approved specification, to spot substitution.
  • Output per day against the ship date.

Worked example: 1,200 side tables

An order of 1,200 mango wood side tables is 35% complete: 420 tables finished, the rest at the cutting and joinery stages. The inspector samples the finished tables and walks the line. Two findings:

  • Legs on finished tables wobble on a flat surface because one batch of legs was cut short. Systematic, so the factory recuts the batch before assembly continues.
  • The stain on new tables is darker than the golden sample. The factory adjusts the mix and the buyer approves a corrected panel.

Found at the final inspection, the same two faults could have affected all 1,200 tables and delayed the ship date. Found here, they cost part of one batch.

When each inspection happens1. Pre-production (PPI): 0% before mass production. Materials, components and golden sample checked. 2. During production (DUPRO): 20–60% of the order complete. Repeat defects caught while they can be fixed. 3. Pre-shipment (PSI): 100% produced, at least 80% packed. Random sample drawn from packed cartons. 4. Loading (Loading supervision): 100% packed, on the stuffing day. Container, carton count and seal checked.

How Clear To Load uses DUPRO

Our DUPRO report records production progress, the defects found by class, and each systematic defect with the action and date agreed with the factory, in effect a short corrective action plan. It ends in a verdict: Cleared to load (production on track), Hold (issues to resolve) or Not cleared (stop and fix). The later pre-shipment inspection confirms the fixes. See during-production inspection in India and the guide on when to book a DUPRO.

Frequently asked questions

Does a DUPRO use AQL sampling?

For finished units, yes, usually on the quantity finished at the time. Work in progress and materials are checked by walking each stage rather than by a formal AQL plan.

Is DUPRO worth it for a repeat order?

Less often. It pays most on first orders, new products, new materials and hand-made goods made across several workshops, where variation is likely.
