Does cargo insurance cover damage caused by poor packing or bad stowage?
Published on October 24, 2026 · Proteus Cargo
Short answer: it depends on who packed, who stowed and what can be proven. Under the market's standard cargo clauses, insufficient packing or preparation of the cargo is a typical exclusion, and it may also extend to stowage inside the container when that is treated as part of the preparation. Stowage carried out by the carrier on board or at the terminal, by contrast, is usually treated by the market as a transit risk, with possible recovery against the carrier. The exact scope always depends on the conditions of each policy and certificate, and it is worth confirming before shipment, not after the damage.
Why this exclusion decides so many claims
Almost any transit damage can be described as a packing problem. The pallet that came apart, the crushed carton, the coil that shifted, the machine that broke loose: in every one of those cases a surveyor can conclude that the cargo "was not prepared for the voyage". And if nobody documented how the shipment left, that conclusion is hard to contradict.
The logic of the exclusion is reasonable: cargo insurance covers the fortuitous, what happens to the goods along the way, not what the goods already carried with them from the plant. A carton that cannot take stacking or a machine with no bracing does not fail because of the voyage; it fails during it, because it was never prepared for it. The practical problem is not the rule but the evidence.
Why it matters who stowed
In the market, stowage is looked at in two ways depending on where it happened and who did it:
- Stowage on board, at the terminal or at the port. When the container is poorly lashed on deck, the stack collapses or cargo is badly arranged in the ship's hold, the damage was caused by the execution of the carriage. In general, the market treats it as a transit risk, the kind of risk cargo insurance usually covers under the applicable conditions, and it also opens the path to recovery against the carrier.
- Stowage inside the container. This is the grey area. Depending on the applicable conditions, the underwriter may read it as preparation of the cargo, that is, as packing. How much it matters whether the insured or a third party, such as the supplier or a consolidator, did it depends on the conditions of the certificate and on what can be proven.
So the useful question for an intermediary is not "was it well packed?" but "who did it, and how do we prove it?".
What to check and document before shipment
- Who packed? — What to check: Whether it was the exporter, a packing facility, the supplier or a consolidator; How to prove it: Name of the responsible party on the packing list or shipping instruction
- Was the packing usual for this voyage? — What to check: Type of cargo, transport mode, transhipments, climate, duration; How to prove it: Packing specification and photos at closing, with the package identifiable
- Who loaded and lashed the container? — What to check: Whether it was the insured, the supplier, a depot or a consolidator; How to prove it: Photos of loading, lashing and the numbered seal; record of who did it
- What condition was the container in? — What to check: Floor, roof, doors, smell, moisture; How to prove it: Inspection or photos at pick-up; a container in poor condition may explain damage later blamed on packing
- Can condition at origin be evidenced? — What to check: High-value cargo, machinery, project cargo, damage history; How to prove it: Report from a recognised inspection company at the time of shipment
- Was recovery preserved? — What to check: The carrier's legal time bars for that mode; How to prove it: Written claim to the carrier within the time bar, even before the amount is known
- What do the certificate conditions say? — What to check: How they treat packing, internal stowage and evidence of origin condition; How to prove it: Review with the Proteus Cargo team before issuing
None of these practices guarantees the outcome of a claim on its own, but all of them strengthen the insured's position against a report that says "inadequate packing".
What the market usually leaves out
- Insufficient packing or preparation, whether by the insured or carried out before the insured transit begins, depending on the applicable conditions.
- Inherent vice of the goods and ordinary wear and tear.
- Damage that existed before the insured transit began.
- Purely financial losses arising from the damage, such as penalties or loss of profit.

What an intermediary gains by explaining this well
A freight forwarder or customs broker who clarifies before the shipment who packs, who stows and what will be documented helps their client avoid one of the most common declinatures in the trade, and moves from vendor of formalities to adviser on the operation.
