What Is the Difference Between Port Storage Fees and Shipping Line Demurrage for UK Cargo?
Many importers shipping cargo from the United Kingdom to Kenya are surprised to discover that they can be charged both port storage fees and shipping line demurrage at the same time.
Although these charges are often confused, they are separate fees imposed by different organizations for different reasons. Understanding the difference can help importers avoid costly delays when clearing cargo through the Port of Mombasa.
What Are Port Storage Fees?
Port storage fees are charges imposed by the port operator—in Kenya, typically the Kenya Ports Authority (KPA)—when cargo or containers remain within the port terminal beyond the free storage period granted after arrival.
In simple terms, storage fees are charged because your container is occupying valuable space inside the port.
For UK imports arriving at Mombasa, KPA grants a limited free storage period. Once that period expires, daily storage charges begin to accrue.
What Is Shipping Line Demurrage?
Demurrage is a separate charge imposed by the shipping line rather than the port authority.
It applies when a container remains at the port terminal beyond the shipping line’s free-time allowance and has not been collected by the importer. The purpose is to encourage quick movement and return of container equipment.
In simple terms, demurrage is charged because the shipping line’s container is being tied up longer than agreed.
Who Charges Each Fee?
| Charge | Charged By | Reason |
|---|---|---|
| Port Storage | Kenya Ports Authority (KPA) or terminal operator | Use of port storage space |
| Demurrage | Shipping line | Delayed collection of the container beyond free time |
This distinction is important because payment of one charge does not eliminate the other.
Can You Be Charged Both?
Yes.
This is one of the most common surprises faced by importers.
If your UK container remains at Mombasa beyond both the port’s free storage period and the shipping line’s free-time allowance, you may be charged:
- KPA storage fees
- Shipping line demurrage
- Additional customs-related costs
- Inspection-related expenses
All at the same time.
Example Scenario
Suppose a container arrives from London and receives:
- 5 free storage days from KPA
- 7 free days from the shipping line
If customs clearance takes 12 days:
- Storage charges may begin after day 5.
- Demurrage charges may begin after day 7.
By day 12, the importer could owe both categories of charges simultaneously.
Common Causes of Both Charges
Importers often incur storage and demurrage because of:
- Missing commercial invoices
- Missing packing lists
- Delayed customs declarations
- Unpaid duties and taxes
- Missing Certificates of Conformity (CoC)
- Regulatory inspections
- Delayed document submission
Most of these issues can be prevented through advance planning.
How to Avoid Storage and Demurrage
Before your UK shipment arrives:
- Submit customs documents early.
- Obtain required permits and certificates.
- Process the Import Declaration Form (IDF) in advance.
- Monitor vessel arrival dates.
- Pay duties and taxes promptly.
- Work with an experienced clearing agent.
The faster a container leaves the port, the lower the risk of additional charges.

Final Thoughts
Port storage fees and shipping line demurrage are not the same. Storage fees are charged by the port authority for occupying space within the terminal, while demurrage is charged by the shipping line for keeping its container beyond the allowed free period. Because both charges can apply simultaneously, importers should prioritize early customs clearance and document preparation to avoid unnecessary costs when importing cargo from the UK to Kenya.
