What Are DEM and DET Fees? Understanding the Difference in Logistics
What Is Demurrage?

What Is Demurrage?
Demurrage (DEM) is a penalty fee incurred when a container remains at the port beyond the free time allowed. This fee typically applies to full containers, aiming to encourage quick removal of containers to reduce congestion at the port.
Common causes of DEM fees:
- Errors or missing documents.
- Delays in customs clearance or cargo inspections.
- Port congestion or labor shortages.
- Consignees abandoning cargo or failing to pay transportation fees.
- Adverse weather conditions or container being rerouted.
What Is Detention?

What Is Detention?
Detention (DET) is a fee charged when an empty container is not returned to the port or shipping line within the allowed free time. This fee encourages businesses to return empty containers promptly to maintain efficient supply chain operations.
Common causes of DET fees:
- Poorly managed transportation schedules.
- Lack of vehicles to transport empty containers.
- Misalignment between production or distribution schedules.

For exports, DEM fees are charged when full containers are delivered to the port but not loaded onto the vessel on schedule. This is often caused by:
- Errors in the shipping line’s schedule.
- Delays from customers or port congestion.
DET fees apply when empty containers are not dispatched from the business’s warehouse to the shipping line on time. Causes include:
- Poor planning or missed deadlines for returning containers.
- Delays in production or packaging processes.
