What Is Demurrage?
Demurrage is a fee charged when a container stays at the port terminal beyond the free time allowed, before it’s picked up (for imports) or before it’s loaded onto the vessel (for exports). Every shipping line grants a set number of free days at the terminal; once that window passes, demurrage charges accrue daily until the container is moved.
What Is Detention?
Detention is a similar concept, but it applies once the container has left the port. It’s charged when a container is kept outside the terminal, at the consignee’s warehouse or premises, for longer than the carrier’s allotted free time before being returned empty to the terminal.
Demurrage vs Detention: Key Difference
| Factor | Demurrage | Detention |
|---|---|---|
| Where the container is | Inside the port terminal | Outside the terminal (at your premises) |
| What triggers it | Container not picked up (import) or not loaded (export) in time | Container not returned empty to the terminal in time |
| Who typically controls the delay | Terminal congestion, customs holds, documentation issues | Unloading speed, warehouse scheduling |
In short: demurrage is a port-side charge, detention is an equipment-side charge once you have the container in your possession.
How to Avoid Demurrage and Detention Charges
- Prepare customs documentation early so clearance doesn’t delay container pickup.
- Arrange trucking in advance so a truck is ready to collect the container as soon as it’s cleared.
- Track your free time window closely, since it varies by carrier and port.
- Unload and return containers promptly to avoid detention once the container reaches your warehouse.
- Communicate with your freight forwarder about expected delays so they can request extensions where possible.
Frequently Asked Questions
How many free days do I typically get before demurrage applies?
This varies by shipping line, port, and sometimes by contract, but a common range is three to seven free days. Always confirm the specific free time for your booking rather than assuming a standard number.
Who is responsible for paying demurrage and detention charges?
Typically the consignee (importer) for import shipments, since they control how quickly the container is cleared and picked up. This should be confirmed in your shipping contract or agreement with your forwarder.
Can demurrage and detention charges be waived?
Sometimes, particularly if the delay was caused by the carrier or terminal rather than the shipper (for example, vessel delays or terminal congestion). It’s worth raising a dispute through your freight forwarder if you believe the delay wasn’t within your control.
Does demurrage apply to export shipments too?
Yes. Export demurrage can apply if a container arrives at the terminal too early or sits waiting to be loaded beyond the free time window, though it’s more commonly discussed in the context of import shipments.
