Detention and Demurrage Fees Explained
Detention and demurrage fees can significantly impact shipping costs, but understanding them helps shippers avoid unexpected charges. This guide covers definitions, differences, causes, calculations, avoidance tips, and 2025 updates for better supply chain management.
What Are Demurrage Fees?
Demurrage fees are charges applied when a container stays too long at a port or terminal beyond the allowed free time. These fees encourage quick cargo movement to prevent congestion.
Ports impose demurrage starting after free days, typically 5-7 days for imports.
Rates escalate daily, doubling after initial periods.
- Applies to loaded or empty containers at terminals.
- Charged by ocean carriers or ports.
- Aims to free up space for new arrivals.
- Common in busy hubs like Singapore or Los Angeles.
- 2025 projections show higher fees due to port bottlenecks.

|---|
| Location | Port/Terminal | Off-Port (Depot/Warehouse) |
