Demurrage and Detention: Understanding and Minimizing Costly Fees in Logistics
TL;DR: Demurrage and detention fees cost shippers millions annually in 2025 due to port congestion and supply chain delays. **This guide explains definitions, 2025 impacts, proven minimization strategies, and tools to cut costs by up to 40% through better visibility and planning.**
Introduction to Demurrage and Detention Fees in 2025 Logistics
Demurrage and detention fees continue to plague global logistics in 2025, driven by persistent port congestion and regulatory shifts.
With no major WCO revisions until 2027, national changes like EU port efficiency mandates and U.S. chassis shortages amplify these costs.
Shippers face daily charges averaging $150 per container, eroding margins amid volatile freight rates.
Demurrage vs Detention: Key Differences Explained
**Demurrage applies inside terminals; detention occurs outside—knowing this distinction saves thousands.**

|---|
| Demurrage | Port/Terminal | Terminal Operator | $100-$300/day | 5-7 days |
| Detention | Outside Port | Ocean Carrier | $75-$250/day | 5-10 days |
Progressive rates kick in after free days, doubling every week in congested hubs like Singapore and Los Angeles.
