What is the difference?
| Charge | Charged by | For |
|---|---|---|
| Demurrage | Shipping line, port or CFS | Container or cargo staying at the port/terminal beyond free days |
| Detention | Shipping line | Keeping the line’s container outside the port beyond free days (until the empty is returned) |
| Ground rent / storage | Port or CFS | Storage of cargo beyond free period |
Why they happen
- Late or incorrect documents, so the Bill of Entry is filed late
- Customs queries, examination or BIS / licence issues
- Delay in duty payment
- Truck not ready or factory not ready to unload
- Empty container returned late
How to avoid them
- Negotiate free days when booking (14–21 days at destination is common to request).
- Send documents early so the Bill of Entry can be filed before arrival.
- Check BIS, licence and HS code before shipment, not at the port.
- Keep funds ready for duty and shipping line charges.
- Plan transport in advance and return empties on time.
Frequently asked questions
Can demurrage be waived?
Shipping lines and terminals sometimes give partial waivers, for example when delay was caused by the authorities, but it is not guaranteed.
When does free time start?
Usually from the date the vessel discharges the container at the destination port.
