A pre-shipment inspection (PSI) is a quality and quantity check performed by a third-party inspector — or sometimes the buyer's own staff — after production is complete but before the goods are loaded for export. It typically checks quantity against the purchase order, visual quality against agreed standards or an approved sample, basic function testing where relevant, and packaging condition.
The value of doing this before loading rather than after arrival is straightforward: a defect caught at the factory can be reworked or the shipment held back, at comparatively low cost; the same defect discovered after a six-week ocean transit means the goods have already incurred their full freight cost and are now sitting at destination as a dispute rather than a production-floor fix.
PSI is a quality function, not a customs or freight function, and we do not perform inspections ourselves — we coordinate pickup and freight around whatever inspection timeline the buyer has arranged, which means the inspection date needs to be communicated early enough that it does not conflict with the planned cargo-ready and pickup dates.
The common scheduling mistake is treating inspection as something that happens "whenever," rather than a fixed point the pickup date depends on — if an inspection finds issues requiring rework, that delay needs to flow into the pickup and booking plan immediately, not be discovered when the truck arrives and the goods are not ready.
