Few logistics charges cause as much frustration as demurrage and detention fees. These costs can appear quickly, escalate fast, and significantly impact transportation budgets when freight does not move on schedule.
In 2026, as ports remain busy and capacity stays tight, understanding how these fees work and how to avoid them is critical for shippers, fleet managers, and logistics teams.
Demurrage and detention are designed to keep freight moving efficiently, but when delays occur, they can turn into expensive line items. The good news is that many of these fees are preventable with the right planning and communication.
Demurrage refers to charges assessed when a container stays at a port or terminal longer than the allotted free time. Once a container is unloaded from a vessel, the clock starts. If the container is not picked up or moved within the free time window, demurrage fees begin to accrue daily.
These charges are meant to encourage fast container turnover and reduce congestion at ports. When containers linger due to paperwork delays, customs holds, or scheduling issues, demurrage costs can grow rapidly.
Detention fees apply when equipment such as containers, chassis, or trailers is held outside the terminal longer than the allowed free time. Once a container leaves the port, shippers have a set number of days to return the empty equipment. If the return is delayed, detention charges are applied.
Detention often occurs due to warehouse congestion, appointment backlogs, or labor shortages at receiving facilities. Unlike demurrage, which occurs at the terminal, detention charges follow the container after it leaves the port.
Increased port congestion, labor constraints, and tighter appointment windows have made demurrage and detention more common in recent years. Even well-planned shipments can encounter delays caused by weather, chassis shortages, or customs processing issues.
As terminals and carriers work to maximize equipment availability, enforcement of free time limits has become stricter. This means there is less flexibility for delays, and fees are applied more consistently.
Avoiding demurrage starts with proactive planning before the vessel even arrives. Tracking vessel schedules closely and preparing documentation in advance reduces delays once the container is discharged.
Scheduling drayage promptly and securing appointments early is also essential. Working with a logistics provider that monitors port activity and communicates in real time helps ensure containers are picked up as soon as they become available.
Clear coordination between customs brokers, carriers, and receivers prevents paperwork bottlenecks that can keep containers stuck at the terminal.
To minimize detention, focus on what happens after the container leaves the port. Ensuring the receiving facility is prepared for timely unloading is critical. This includes confirming dock availability, labor readiness, and appointment times before the container arrives.
Efficient unloading processes and quick empty returns help keep equipment moving and reduce detention risk. Pre-planning return locations and chassis availability can also prevent delays once unloading is complete.
Real-time visibility plays a major role in avoiding both demurrage and detention. Knowing where containers are, how much free time remains, and when milestones are approaching allows teams to act before fees apply.
Open communication between all parties involved helps resolve issues quickly when delays occur. Early notification can sometimes lead to adjustments or solutions that prevent unnecessary charges.
Tool and strategies modern teams need to help their companies grow.
