Demurrage and Detention Charges in Oman: Free Time, Port Storage and Carrier Tariffs
Delays in customs clearance, Delivery Order processing, trucking, unloading or empty container return can become expensive quickly. Demurrage and detention charges in Oman may start at different points and follow different tariff rules, while port storage and reefer costs may be billed separately. Knowing which clock is running helps cargo owners keep avoidable costs under control.

What Do Demurrage and Detention Mean?
The difference starts with the container’s location. Demurrage generally applies while the carrier’s container remains inside the port, terminal or depot after free time has expired. Detention generally applies once the container has left the terminal and is kept beyond the permitted return period.
Some carriers combine both periods into a single charging window called Combined Demurrage and Detention. Port Storage is separate. It is charged by the terminal for the space occupied by the container and may run alongside carrier charges.
| Demurrage, Detention and Port Storage Compared | |||
|---|---|---|---|
| Charge | Container location | Charged by | Starts when |
| Demurrage | Inside the port, terminal or depot | Carrier | Carrier free time expires |
| Detention | Outside the terminal or depot | Carrier | The empty container is returned late |
| Combined D&D | Inside and outside periods | Carrier | Combined free time expires |
| Port Storage | Inside the terminal | Terminal operator | Terminal free storage expires |
How Does Free Time Work in Oman?
Free time is only useful if you know which clock it refers to. In Oman, a carrier may start counting import free time from vessel arrival or container discharge, then follow the container through terminal stay, gate-out, unloading and empty return. For exports, the clock may begin when the empty container is released and continue until the laden unit is gated in or loaded on board.
Rules vary by shipping line. Many tariffs use calendar days, so weekends and public holidays may still count. Dry, reefer and special equipment can also have different allowances. Always check the booking confirmation and the carrier’s current tariff before planning the move.
Port Storage vs Carrier Demurrage and Detention
Carrier charges and terminal charges are often confused because they can build up during the same delay. Demurrage and Detention relate to the use of the shipping line’s container. Port Storage, by contrast, is charged by the terminal for the space the container occupies.
A shipment can incur Carrier D&D and Port Storage at the same time, even though each may have its own free period and starting point. Reefer containers may also attract separate charges for plugging, electricity and monitoring. At Sohar and Salalah, terminal storage terms should be checked alongside the carrier’s tariff.
Examples of Published Carrier Tariffs in Oman
Carrier tariffs in Oman do not all follow the same pattern. Even for standard dry containers, free time and charging models can change from one shipping line to another.
| Published Carrier Examples | |||
|---|---|---|---|
| Carrier | Import Dry Free Time | Export Dry Free Time | Charging model |
| OOCL | 5 calendar days | 7 calendar days | Combined D&D |
| Maersk | 3 calendar days | 10 calendar days | Combined D&D |
| Hapag-Lloyd | 5 calendar days | 7 calendar days | Import demurrage combined with detention; Export detention |

These examples are for general guidance only. Terms may differ by booking, equipment type, terminal, shipment date and customer agreement. The carrier’s current confirmation remains the final reference.
A Simple Demurrage and Detention Calculation Example
Suppose an imported 40-foot Dry container has a 12-day Combined D&D period before empty return. Based on the published OOCL Oman tariff reviewed in June 2026, the first 5 days are free, leaving 7 chargeable days.
5 free days
4 days × OMR 22 = OMR 88
3 days × OMR 40 = OMR 120
Total Carrier D&D: OMR 208

How to Avoid Demurrage and Detention Charges
Avoiding extra charges usually comes down to planning the container’s next move before it arrives.
Demurrage Prevention Checklist
. Confirm free time in the booking confirmation.
. Check Carrier D&D and Terminal Storage separately.
. Prepare customs documents before vessel arrival.
. Arrange the Delivery Order and payments early.
. Reserve trucks, labour and warehouse capacity.
. Confirm the empty-return depot and receiving hours.
. Account for weekends and public holidays.
. Request extensions before free time expires.
. Keep gate-out and empty-return receipts.
. Document external delays in writing.
. Track estimated charges until empty return.
In one Sohar container case handled by ICIT, several issues overlapped: Delivery Order timing, public holidays, limited operating space, transport coordination and delayed empty return. The lesson was simple: once free time is running, daily tracking, written evidence and early escalation matter more than last-minute negotiation.

Who pays demurrage and detention charges in Oman?
It depends on the booking, bill of lading terms and agreement between the shipper, consignee and cargo owner.
Does port storage include carrier demurrage?
Usually, no. Port Storage is charged by the terminal, while demurrage is charged by the carrier for container use.
Are weekends and public holidays included in free time?
Often, yes. Many tariffs use calendar days, so weekends and public holidays may count unless the tariff says otherwise.
Is laytime the same as container free time?
No. Container free time relates to container use. Laytime relates to vessel loading or discharge under a charter party.
