Demurrage and detention in Abidjan: understanding them to avoid them
An importer receives three invoices for a single container immobilised for three weeks. They dispute one, negotiate the second, ignore the third — and end up in litigation. The problem is not the amount: it is that three different debts were treated as one.
Telling these meters apart is the first competence to acquire when you import regularly. This article explains their mechanics. It quotes no tariffs: the schedules are contractual, they vary by carrier, container type and period, and only your contract or booking governs.
Three meters, three creditors
- Demurrage
- Owed to the carrier. It penalises keeping a full container on the terminal beyond the free time granted. The meter starts when free time ends and stops when the container leaves the terminal.
- Detention
- Also owed to the carrier, but for a different period: the time during which you retain the container after gate-out, while you unstuff it and return it. The meter stops when the empty is returned to the designated depot.
- Port dwell charges
- Owed to the port authority or terminal operator for occupying space. They are independent of who owns the container and run under their own schedule, generally from discharge.
The same container can generate demurrage and dwell charges simultaneously: the first meter compensates the immobilisation of an asset belonging to the carrier, the second the occupation of space belonging to the port. Settling one does not extinguish the other.
Free time: the starting point nobody checks
Free time is the period during which the carrier applies no demurrage. Its duration is not standard: it depends on the contract of carriage, the container type, the destination and sometimes on a commercial negotiation tied to volume. Two containers arriving on the same vessel may have different free time if they fall under two distinct bookings.
The most common mistake is to rely on a rule remembered from a previous operation. The rule is simple: never assume free time, always open the contract or the booking, and record it in the file as soon as the shipment is confirmed.
Check the counting method too: calendar days or working days, inclusion or exclusion of the discharge day, treatment of public holidays. A one-day gap on the starting point shifts the whole schedule, particularly where it is tiered.
Why schedules are tiered
Demurrage schedules are almost always built in rising tiers: the first days of overrun are charged at a moderate rate, the following ones at a higher rate, and so on. The logic is deterrent: this is not about billing a service, but about discouraging the immobilisation of an asset the carrier needs elsewhere.
The practical consequence is counter-intuitive. A three-day delay costs little; a fifteen-day delay does not cost five times more, it costs a great deal more. That is why the real question is never how much a day of delay costs, but from which day the cost changes regime.
Where the days are actually lost
Container immobilisation rarely results from a single cause. It accumulates in small increments, each tolerable in isolation.
| Cause of delay | Meter affected | Lever |
|---|---|---|
| Mandatory document obtained after arrival | Port dwell and demurrage | Handle pre-shipment formalities as soon as the order is confirmed |
| Mismatch between invoice and bill of lading | Port dwell and demurrage | Have commercial documents reviewed before loading |
| Shipping agent's charges settled late | Port dwell and demurrage | Provision funds and pay on receipt of the charge note |
| Client site unavailable for unstuffing | Detention | Fix the delivery slot before gate-out |
| Empty returned without urgency after unstuffing | Detention | Organise the return immediately after unstuffing |
Reducing exposure: what actually works
Open the contract, not your memory
Record the actual free time and its counting method as soon as the shipment is confirmed, and note it in the file. It is the cheapest action and the one that prevents the most.
Move the documentary burden upstream
Send commercial documents and start pre-shipment formalities as soon as the order is placed. An inconsistency caught before loading costs nothing; caught on the quay, it is paid in days.
Provision for shipping charges
The delivery order conditions gate-out. Planning the corresponding cash before arrival avoids leaving a perfectly assessed customs file blocked for want of payment.
Fix the unstuffing slot before gate-out
Taking a container out without a confirmed unstuffing slot simply transfers immobilisation from the terminal to your own yard — changing meters, not costs.
Treat the return as a step, not a formality
The empty must leave for the designated depot as soon as unstuffing is complete. Every day an empty container sits on site is a day of detention billed.
Reconcile invoices line by line
Match each invoice to its triggering event: discharge date, gate-out date, empty return date. A dispute only succeeds if it names the right date and the right creditor.
On a regular flow, keep a simple table per container: discharge date, end of free time, gate-out date, empty return date. Four dates are enough to reconstruct all three meters and to dispute an invoice with evidence that stands.
When warehousing becomes the rational option
Sometimes an importer simply cannot absorb a consignment immediately: a full warehouse, a delayed site, seasonality. Leaving the container immobilised in the meantime is the worst option, since the schedule is tiered. Unstuffing the goods and placing them in a warehouse turns a rising cost into a linear one, and frees the container.

It is a matter of sequencing: every day moved from downstream to upstream is a day removed from the most expensive meter.
- What is the difference between demurrage and detention?
- Demurrage covers the period during which the full container remains on the terminal beyond free time. Detention covers the period during which you retain the container after gate-out, until the empty is returned. Both are owed to the carrier, but they cover different phases.
- Are port dwell charges the same as demurrage?
- No. Dwell charges are owed to the port authority or terminal operator for occupying space, under their own schedule. Demurrage is owed to the carrier for immobilising its container. Both can run at the same time.
- Is free time the same for every container?
- No. It depends on the contract of carriage, the container type and sometimes on commercial arrangements tied to volume. Two containers from the same vessel may have different free time. Only the contract or booking governs.
- Can demurrage already incurred be waived?
- That is a commercial discussion, not a right. It stands a better chance when supported by documented dates and by an identifiable cause of delay outside the shipper's control. A generic request with no supporting documents rarely succeeds.
