What they mean, how they differ from storage, and how to avoid charges
What are Demurrage and Detention?
Demurrage and detention are shipping line charges that apply when free time on a container is exceeded. Demurrage applies while the full container sits inside the port or terminal. Detention applies after the container is gated out and kept beyond the allowed period before returning it.
At a Glance: Demurrage vs Detention vs Storage
| Term | Where it applies | Who charges it | Typical trigger |
|---|---|---|---|
| Demurrage | Inside port/terminal (full box) | Shipping line | Exceeding free days before pickup |
| Detention | Outside port (usually empty box not yet returned) | Shipping line | Exceeding free days before returning container |
| Storage | Port/terminal or warehouse | Port/terminal or warehouse operator | Space usage beyond free time |
Common Causes
- Customs clearance delays or missing documents.
- No haulage slot booked within free time.
- Delivery site not ready or restricted access hours.
- Slow unpacking and late return of the empty container.
How to Avoid Charges
- Prepare customs entries and documents before vessel arrival.
- Pre-book Container Haulage to collect promptly.
- Confirm delivery windows and unloading resources in advance.
- Return empties quickly to the correct depot; check line instructions.
