Demurrage and detention are the purest waste in importing. They buy you nothing, they are entirely predictable, and they are almost always the result of a sequencing failure rather than bad luck. Here is how they work and how to make sure your business never pays them.
The difference between the two
| Charge | What it is | Who charges it |
|---|---|---|
| Demurrage | Charged for leaving a container inside the terminal beyond the allowed free period after discharge. | The shipping line, and in effect the terminal. |
| Detention | Charged for keeping the container outside the terminal — at your premises — beyond the free period before returning it empty. | The shipping line. |
| Storage | Charged by a depot or terminal for holding cargo or containers. | The depot or terminal. |
Why importers get caught
- Clearance started after arrival. If the entry is lodged when the vessel berths rather than before, several free days are gone before anything can move.
- Documents arrived late. A missing certificate of origin or an invoice that does not match the packing list stops the entry.
- Biosecurity intervention nobody planned for. An inspection or fumigation adds days, and the clock keeps running.
- No transport booked. Truck capacity and terminal slots are finite, particularly at the end of the week and before public holidays.
- Nowhere to unload. A container arrives at a site with no forklift, no dock or no staff, and has to be re-delivered.
- Public holidays and shutdowns. Free days are usually calendar days, not working days.
The seven habits that keep it at zero
Lodge the entry before arrival
This is the single highest-value habit in importing. Where the forwarder also holds the customs work, it should be automatic. See customs clearance.
Check documents at cargo-ready, not at arrival
Ask for the invoice, packing list, draft bill of lading and origin certificate while the goods are still at origin. Errors are free to fix then.
Raise biosecurity risk before shipment
Timber packaging, used equipment and anything with plant or animal content should be assessed before booking, not after arrival.
Book transport against the ETA, not the arrival
Slots get booked out. Provisional bookings can be moved; missing capacity cannot be created.
Confirm the unload plan in writing
Who is on site, what equipment they have, and what the delivery window is.
Watch the calendar
Count your free days across weekends and public holidays. If the container lands on a Thursday before a long weekend, act accordingly.
Have a fallback
If your site cannot take the container in time, devanning at a depot and delivering loose or palletised is almost always cheaper than detention. See warehousing.
If you are already accruing charges
Act immediately rather than negotiating. Demurrage escalates in tiers, so day seven costs considerably more than day two. Get the container out of the terminal even if it means unpacking at a depot, then sort out the underlying problem. Carriers will occasionally waive charges where the delay was caused by a documented terminal or biosecurity issue, but only if you ask promptly and with evidence.
If the container is already out and the problem is that you cannot get the empty back to the park, that has its own set of fixes: see container detention charges when you cannot return the empty.
The honest summary
If you are regularly paying demurrage or detention, the cause is almost never the shipping line. It is the sequence in which your shipments are being handled. That is fixable, and it is one of the first things we look at when we review a new client’s freight. Talk to us or call 1300 972 040.
