Pre-shipment inspection
Pre-shipment inspection — A structured look at finished goods at the supplier's warehouse while they are still the supplier's problem — quantity checked against packing list, workmanship sampled against an agreed standard, and cartons checked for the marks your customs paperwork will carry.
The 80 % rule
The 80 % rule — The earliest moment an inspection is meaningful: when at least 80 % of goods are finished and at least 60 % packed. Earlier and you inspect a sample of intentions; later and the container is already booked and the leverage has evaporated with the timeline.
| Quantity and packing errors | wrong counts, wrong mixed ratios — found at sea they become your stock shortage |
|---|---|
| Workmanship drift from the approved sample | finish, colour, assembly: compared against the golden sample, not feelings |
| Carton marks against paperwork | the mismatch that stops a customs clearance is usually on the box |
| Functional spot-checks | the one test your product needs — switched on, assembled, weighed, measured |
| Photos of every stage | the inspection's real deliverable: the evidence file you negotiate with |
Inspection is a calendar decision, not a quality decision
The moment you book the inspection matters more than who does it. At 80 % finished and 60 % packed, problems are still rework — recount, repack, reprint labels — and rework is cheap inside a supplier’s own walls. On the day the container is booked, every finding becomes a choice between missing the sailing and shipping the defect, and that choice was made by the calendar, not by anyone’s standards. Buyers who inspect well are mostly buyers who scheduled well: the inspection slot belongs on the purchase order, with the payment terms leaning on it.
The report you will actually re-read
Nobody re-reads “PASS.” The report worth requesting carries numbers — how many cartons opened, how many pieces checked, how many defects found and of which class — plus the photo set: a wide shot of the pile, a close shot per defect, and the paperwork held beside the carton marks. That file is what you negotiate with when the next order discusses price, what you show an insurer, and what settles arguments with customers about what shipped. Request the file, not the verdict.
Paying for inspections that pay for themselves
A visit costs against the order, not against the invoice: a fixed-day fee on a small order can be a percentage that makes the import pointless, while on a container it disappears. The pattern that makes inspections economic is grouping — inspecting all of a quarter’s orders from one factory in one visit, the way consolidators do — and the pattern that makes them wasted money is inspecting what your own receiving check would catch anyway, one week after it would still have been fixable at origin.
Who runs the inspection — me, the supplier, or a third party?
On reorders with a proven supplier, your own checklist run by their QC team is normal. On a first supplier in a category, an independent inspector is the cheapest insurance you will ever buy, because the report is written by someone whose product is the truth, not the sale. The mistake is not using third parties at all; the other mistake is using them on orders too small to pay for the visit.
What happens when an inspection fails?
Usually not what dramas suggest. Most findings are fixable on the spot — re-counts, re-pack of a few pallets, a carton-mark correction — and the inspection earns its fee by making the fix happen while goods sit under the supplier's roof. The failure that matters, systematic workmanship drift, stops the shipment and starts a real negotiation with photo evidence attached — the version of that conversation where you hold paper instead of hope.
