If you’ve ever imported goods through the Port of Mombasa, you’ve likely heard of demurrage and detention charges.

These are some of the most frustrating and costly expenses importers face — often unexpected and avoidable.

In this guide, you’ll learn:

• What demurrage and detention mean
• The difference between them
• How they are charged in Kenya
• Real-life cost examples
• Proven ways to avoid them

Understanding this can save you thousands in unnecessary charges.

What Is Demurrage?

Demurrage is a fee charged when your cargo stays at the port or terminal longer than the allowed free period.

This happens when:

• Your container is not cleared on time
• Documentation is incomplete
• Taxes are not paid promptly
• There are customs delays

Simple explanation:

Demurrage = Paying for cargo staying too long at the port

---

What Is Detention?

Detention is charged when you take the container out of the port but delay returning the empty container to the shipping line.

Simple explanation:

Detention = Paying for keeping the container too long outside the port

---

Key Difference Between Demurrage and Detention

Charge Type	Where It Happens	When It Applies
Demurrage	Inside port/terminal	Cargo not cleared on time
Detention	Outside port	Container not returned on time

Both can apply to the same shipment — and costs can escalate quickly.

How Demurrage Charges Work in Kenya

Shipping lines and port operators usually offer a free period (e.g., 3–7 days).

After that:

• Charges increase daily
• Rates increase progressively (day 1–5 lower, day 6+ higher)

Example:

• Free period: 5 days
• Day 6–10: KES 5,000/day
• Day 11+: KES 10,000/day

If your cargo delays by 10 days:

→ You could pay KES 50,000+ in demurrage alone

---

How Detention Charges Work

Shipping lines also give a free container usage period.

If you delay returning:

• You pay daily detention charges
• Rates depend on container size (20ft / 40ft)

Example:

• Free period: 7 days
• After that: KES 4,000/day

If you delay 5 days:

→ You pay KES 20,000 detention

Real-Life Scenario

An importer delays clearing goods due to:

• Missing IDF
• Late duty payment
• Incorrect HS code

Result:

• 7 days demurrage = KES 35,000
• 5 days detention = KES 20,000

Total loss: KES 55,000 — avoidable
