Pre-Shipment Inspection

Also known as: PSI, Final Random Inspection, FRI

A quality check carried out when production is at least 80% complete and packed, in which an inspector samples finished goods before the buyer pays the balance and the goods ship.

A pre-shipment inspection normally covers quantity, workmanship against the AQL plan, functional checks, measurements, packaging and labelling. It is the buyer's last practical chance to have defects fixed in the factory.
