Buyers who have started using pre-shipment inspection often assume they are covered. Then a container arrives with the right total quantity and the wrong mix of sizes, or with a fifth of the cartons crushed, and they discover that inspection and loading are two different events.
The gap
A pre-shipment inspection happens when production is finished, usually a few days before loading. Between the inspector leaving and the doors closing, a lot of physical handling happens with nobody watching who works for you.
That handling is done at speed, usually by workers who were not present at the inspection, against a packing list that may or may not be the one your inspector reconciled.
What actually goes wrong
Short shipment. The most common and the most expensive. The count in the container does not match the packing list. Discovered at your warehouse six weeks later, it is a claim; discovered in the factory yard, it is a conversation.
SKU substitution. The total is correct and the mix is not. Eighty units of the size that sells and forty of the size that does not, reversed. This is often not malice — it is a picker working from a Turkish-language list under time pressure — but the commercial effect is identical.
Crushing. Heavy cartons stacked on light ones. The damage looks exactly like transit damage, which means your claim goes to the carrier, who declines it, because it happened before the container moved.
A container that should have been rejected. Dented, previously repaired, damp, or carrying an odour from a previous cargo. It arrives at the factory, the schedule is tight, and someone decides it will be fine. Textiles and food-adjacent goods absorb odours permanently.
Missing documents. Certificates, packing lists or export marks that should be physically inside the container, and are not.
Seal mismatch. The seal number on the bill of lading is not the number on the door. This turns a routine customs formality into a week of correspondence, and it invalidates the chain of custody if you ever need to prove the container was not opened.
What supervision looks like in practice
Before loading. The empty container is inspected: structural condition, cleanliness, dryness, previous repairs, odour. The container number is photographed against the booking. A container that fails this is rejected before anything goes into it, which is the only moment rejecting it is cheap.
During loading. Cartons are counted as they cross the door — not counted on a pallet in the yard and assumed to have all gone in. The stack pattern is photographed at intervals. Weight distribution is checked. If the count diverges from the packing list, loading stops and the buyer is called before the doors close.
Sample verification. Random cartons are opened at the door and the contents checked against the label and the packing list. This is the cheapest defence against SKU substitution that exists, and it takes ten minutes.
Sealing. The doors are closed and sealed with the supervisor present. The seal number is photographed on the seal and on the door, and recorded in the report against the bill of lading number.
Same-day report. Photographs, final count, seal number, container number and any deviation, sent while the truck is still on its way to the port — so that if something is wrong there is still time to act.
The timing constraint
Loading supervision has to be booked at least 72 hours ahead, and this is not administrative caution. It has to be synchronised with the factory’s truck booking, and in Türkiye trucks arrive early more often than they arrive late. A supervisor who turns up at the confirmed time to find the container sealed and gone has bought you nothing.
If you take one thing from this: ask your supplier for the truck slot, not the loading day.
When to use it
Not on every shipment. Sensible triggers:
- The first three shipments from any new supplier
- Any order with multiple SKUs or size runs
- Any product where crushing or moisture is a real risk
- Any shipment after a failed or marginal inspection
- Any order large enough that a five per cent short shipment matters
Combined with a pre-shipment inspection on the same visit it costs very little extra, because the inspector is already there. That combination — inspect Tuesday, load Thursday, same person — is the most cost-effective quality arrangement available to a mid-sized importer buying from Türkiye.
