Pre-Shipment Inspection (PSI), also known as Final Random Inspection, PSI helps ensure that production complies with the governing specification, contract, or purchase order. A final random inspection (FRI) checks finished products, often when at least 80% of an order has been produced and export-packed. Samples are selected at random, according to standards and procedures. QCC INSPECTION uses ISO 2859 tables as its sampling standard and acceptable level of quality.
