Key takeaways
- Dwell time measures idle time at a point in the journey.
- It ties up containers, trailers, and drivers as unproductive assets.
- It is a leading cause of demurrage and detention charges.
- Cutting it takes live visibility and fast exception handling.
How is dwell time managed?
Dwell time accrues wherever freight waits: a container sitting at the terminal, a trailer parked in the yard, a load stuck at a dock. Each hour of dwell is an asset not moving and, often, a free-time clock ticking toward a penalty. Measuring it by location and cause is the first step.
Reducing dwell time depends on visibility and speed: knowing what is waiting where, and clearing it before it becomes a cost. A control tower surfaces the idle assets and the reasons, so teams schedule pickups, appointments, and returns in time. InfoSun turns that tracking data into timely action.
Why reducing dwell time matters
- Frees containers, trailers, and drivers to keep moving.
- Cuts demurrage and detention charges.
- Speeds deliveries and improves service.
- Surfaces the bottlenecks worth fixing at the source.
Dwell time in a 3PL and logistics operation
A logistics operation puts container and trailer status into a control tower and tracks dwell by location. It finds trailers dwelling in the yard for want of dock appointments, adds appointment scheduling, and cuts the idle time, which also removes the detention charges the dwell was causing.
Frequently asked questions
What causes high dwell time?+
Common causes include missing appointments or chassis, congested yards and terminals, slow customs clearance, and slow unloading or empty returns. Each leaves freight or equipment idle at a point in the journey. Measuring dwell by location and cause is what reveals which bottleneck to fix.
How is dwell time related to demurrage and detention?+
Dwell time is the idle time; demurrage and detention are the charges that idle time triggers once free time is exceeded. Reducing dwell, by clearing containers and equipment faster, directly reduces those charges, which is why visibility into dwell pays for itself.
