A container arrives in Lagos, Abidjan or Dakar and the cartons have gone soft. Metal fittings have a film of rust. Food product has clumped or the labels have peeled off the tins. The exporter’s first instinct is to blame the port, the buyer’s warehouse, or bad luck. Nine times out of ten the real cause is simpler: the packaging was specified for a European or Asian domestic run, not for weeks of heat, humidity and rough handling on the way to West Africa. Tropical climate packaging is not an upgrade you add if the budget allows it. For this route, it is the packaging spec.
Why standard packaging does not survive the journey
Packaging designed for a European pallet network assumes a dry warehouse, a short transit, and handling equipment that treats the load gently. None of that holds on a West Africa run. Relative humidity inside a closed container can climb well above what the cargo left the factory in, and temperature swings between a hot quay and a cooler hold cause condensation on the inside of the container walls and roof — often called container rain. Add dwell time at the port of discharge, where cargo can sit for days or weeks waiting on customs clearance, and cartons that looked perfectly adequate on departure are collapsing before they ever reach a distributor’s shelf.
Building in a real moisture and heat barrier
Single-wall corrugate that is fine for a domestic delivery is usually the wrong specification for this route. Points worth checking before you commit to a supplier’s standard box:
- Use double or triple-wall board, or a water-resistant coating, for anything travelling more than a few weeks.
- Add a moisture barrier liner or shrink wrap inside the carton, not just around the pallet.
- Include desiccant or silica gel sachets for electronics, machinery parts and anything with exposed metal.
- Specify a corrosion inhibitor or VCI paper for metal components rather than relying on the original coating alone.
- Test glue and label adhesives for heat and humidity — labels that lift in transit create their own compliance problem at customs.
None of this needs to be expensive. It needs to be decided at the packaging design stage, not discovered after a claim comes in.
Wood packaging and the ISPM 15 requirement
If pallets, crates or dunnage are made of solid wood, they need to meet ISPM 15 — heat treatment or fumigation, followed by the official stamp on the wood itself. This is checked by phytosanitary or quarantine officers at the port of entry, and non-compliant wood packaging can be rejected, treated on the spot at the importer’s cost, or held while the shipment is inspected. It is a small detail that has stopped containers moving at destination more than once. If you are not certain your pallet supplier’s stamp is genuine and current, ask for the treatment certificate, not just a photo of the mark.
Container loading choices that affect packaging
How the cargo travels changes what the packaging has to withstand. Consolidated cargo in a shared container is handled more times, sits longer at transhipment points, and is more exposed to condensation from other shippers’ goods in the same box — one more reason the choice between FCL and LCL matters as much for packaging as it does for cost and transit time. A full container gives you control over loading pattern and ventilation, but only if it is loaded correctly — mixed pallet heights, wet dunnage or cargo loaded straight after rain will trap moisture inside a sealed box for the whole voyage.
What happens during the wait at port
Packaging specified for a fifteen-day transit is being tested against a very different reality once the container is sitting on a quay in direct sun, waiting on documentation or a customs query. This is where the freight forwarding side of the operation matters as much as the box itself: a forwarder who knows the port and keeps documentation moving reduces the time your packaging has to survive under worst-case conditions. It is worth reading how to go about choosing a freight forwarder for this route alongside your packaging review, because the two decisions are related — the better the clearance process, the less your packaging has to absorb.
That wait is rarely a quiet one. A container can sit in the yard while customs queries, demurrage negotiations or inland transport are sorted out, and it usually does so in direct sun with no ventilation. Packaging specified to survive the sea crossing alone, with no margin for extended dwell time, is packaging specified for the wrong journey.
When it goes wrong: evidence and claims
If damage does occur, what happens next depends heavily on what was documented at loading and at arrival. Photograph the packaging and the loading pattern before the doors close, keep the packing list matched to what was actually loaded, and make sure any pre-existing condition of pallets or cartons is noted rather than assumed. On arrival, damage needs to be recorded on the delivery documents before the consignee signs for the goods, not after.
Whether that damage is recoverable then depends on the cargo cover in place and what it actually excludes, which is exactly where many exporters discover gaps only after a claim is filed. It is worth understanding in advance who pays and what standard cargo cover actually includes, rather than assuming a marine policy covers condensation or inadequate packaging by default — most do not.
Before the next shipment
A few checks before your next container:
- Ask what climate the current packaging spec was actually designed for — most standard specs were not built with a four-to-six-week tropical transit in mind.
- Get the ISPM 15 treatment certificate for any wood packaging, not just the stamp.
- Build in a moisture barrier and, where relevant, a corrosion inhibitor, rather than relying on the carton alone.
- Ask your buyer what has failed on previous shipments — packaging faults show up as claims, and claims history is the most honest packaging audit you will get.
None of this replaces a proper transit test if the product or the route is new. But it will stop the most common and most avoidable losses on the way to West Africa.
