Pre-Shipment Inspection: What the Report Must Contain Before You Pay the Balance

The balance payment is the last moment you have real leverage. After it, a defect becomes a negotiation. Everything in this article exists to make sure you have already decided, before that payment, whether the goods are acceptable.

Inspection is four checkpoints, not one

Pre-production. The first article off the line, measured against the signed sample. Catches the case where the factory built to a drawing you changed three months ago and never re-issued.

In-line. Roughly 20–30% into production. This is the cheapest inspection to run and the most valuable, because a systematic error found at 400 units costs a rework, not a replacement.

Pre-shipment. Finished, packed, in cartons, at the loading port. This is the one that gates payment.

During loading. Container number, seal number, pallet count, and photos of the loaded container before the doors close. Cheap, and it settles disputes about what was shipped.

How AQL sampling actually works

You do not inspect the whole order; you inspect a statistically defined sample and accept or reject the lot. The usual arrangement is two defect levels — critical, major, minor — with acceptance limits such as 0 / 2.5 / 4 on a sample of 200 units from an order of 8,000.

Three things to agree in writing before production starts, not on inspection day:

• The AQL levels, and who pays for a re-inspection after a fail.
• What counts as critical. For a battery product, a cell without protection circuitry is critical. For a candle, a wick that produces a flame above the tested height is critical.
• The reference for "correct": the signed sample, the approved artwork, and the packing list. If those three disagree, the inspection becomes an argument.

What a usable report contains

A report that says "passed" is worth nothing. You want the artefacts:

• Order reference, quantity inspected, sample size, and the AQL applied.
• Measured values against tolerance — actual numbers, not ticks. Weight, dimensions, wall thickness, colour reading, and the tolerance you specified.
• Function tests performed, with the method. For electronics: charge, run time, button response, protection cut-off. For fragrance: burn behaviour and throw. For silicone: Shore hardness or a tear test.
• Workmanship defects, photographed and counted by type and severity, each pinned to a carton number.
• Packaging checks: barcode scan, carton mark, drop test result, inner-pack quantity, and accessory completeness against the packing list.
• On-site video of the packing line, and the container seal photo at the end.

The four failures inspection catches most often

Material substitution one grade below the approved sample. Accessory omission — the manual, the cable, the remote. Print and colour drift on packaging across production batches. And quantity shortfalls in mixed cartons that only show up when someone counts at the far end.

What to do when it fails

Hold the shipment, do not release the balance, and send the report to the factory the same day with a specific ask: rework, replace, or discount, quantified per defect. A factory that respects you will rework. A factory that argues about the definition of a minor defect has told you what your next twelve months will look like.
