Connecting sample approval to pre-shipment inspection

An approved prototype does not prove that a production lot matches it. Before shipment, give the inspector the final drawing, golden-sample ID, packaging revision, and purchase-order quantity. Decide the inspection scope early enough to act on a failure.

Verify the actual lot

Confirm production completion, lot identification, cartons available, and access to goods. The inspection plan should state sample selection, defect definitions, dimensional or functional checks, and how results will be recorded. If attribute sampling is used, choose the plan for this product and lot; do not claim that a generic sample count guarantees quality.

Make release a decision

Receive the report with photos and raw measurements. Compare the findings with the agreed acceptance rules, then record release, hold, rework, or reject. A supplier correction should be verified under a defined retest method. Keep the inspection result linked to the shipment and payment milestone it affects.

Worked shipment gate

The supplier says 500 units are packed under purchase order PO-18. Give the inspector the approved sample S-6, drawing F-3, and packaging P-2. Enter the reference and any observed deviations in the sample review tool for a summary, but keep the full lot sampling report and photos attached separately. Common error: releasing the shipment after seeing S-6's earlier approval while no production units have been inspected. Put the actual inspection disposition beside the payment and shipping release decision.
