Pre-shipment Inspections (QC Inspections)

Pre-shipment inspection (PSI) is the full QC inspection of the product quality before the goods are shipped to assess if the overall quality of the products meets the requirements before shipment.

Typically the PSI is based on the inspection and acceptance criteria that have been agreed to by the customer, including the determination of the Acceptance Quality Level (AQL), the general sample level and the sample size.
