Demurrage & Detention Explained

Understand and avoid the most common hidden costs in ocean freight

Demurrage and detention are fees charged by shipping lines to ensure the quick turnaround of their containers. When containers are tied up for too long, shipping lines lose money. These fees can quickly wipe out the profit margin of a shipment if not managed properly.

Demurrage

Charged when the full container is inside the port/terminal beyond the allotted free days. It penalizes the importer for taking too long to pick up their cargo from the port.

Detention

Charged when the container is outside the port/terminal beyond the allotted free days. It penalizes the importer for taking too long to return the empty container to the depot.

How to Avoid These Charges

  • Pre-clear Customs: Ensure all documentation and customs clearance are handled before the vessel arrives.
  • Negotiate Free Time: Ask your forwarder to negotiate extended free days with the carrier before booking.
  • Use Software Alerts: Use a platform like ShippEasy that automatically tracks free time and sends alerts before charges begin.
