What is Pre-shipment inspection?
A pre-shipment inspection is a quality check of finished goods at the factory before they are shipped, usually when production is complete and most of the order is packed.
An inspector checks quantity, appearance, function, labelling and packaging against the order, on a random sample of cartons.
It is the last point at which defects can be fixed cheaply. After the goods leave China, returning or reworking them is rarely practical.
