Your container might roll into Mombasa on time, but if you’re not careful, the final bill could catch you off guard. Why? Because the clock for port storage doesn’t tick the same as the clock for shipping-line demurrage. And once you’ve unpacked your cargo, there’s yet another timer running: detention charges for the empty container.
For Kenyan importers, knowing the difference between these charges and their deadlines can be the key to avoiding costly surprises and ensuring smooth clearance.
At the Kenya Ports Authority (KPA), storage fees kick in when your cargo overstays the free period at the terminal. Shipping lines, on the other hand, charge demurrage when their containers linger past the carrier’s allowed free time inside the terminal. Detention fees come into play after the container leaves the terminal, but the empty box isn’t returned within the agreed timeframe.
Why does this matter? Because you could end up paying KPA storage and shipping-line demurrage fees at the same time. And if you delay returning the empty container, detention charges add to the bill.
The free storage you get depends on your cargo type. According to KPA’s current tariff, domestic import containers enjoy five consecutive free storage days, while transit import containers get 15 days.
After those free days, charges kick in. For domestic imports, storage costs USD 30 per day for a 20-foot container and USD 60 for a 40-foot container from day six to day 21. Beyond day 21, the daily rates jump to USD 50 and USD 100 respectively. Transit imports face these rates starting from day 16 to day 21, before they increase.
Keep in mind, these are KPA’s storage terms. Shipping lines often have their own free periods before demurrage sets in, so always check your carrier’s terms or arrival notice.
Most delays are avoidable and happen during clearance.
Incomplete or mismatched documents can trigger queries. If commercial invoices and customs paperwork don’t match in value, quantity, or description, expect holdups.
Late pre-arrival processing eats into your free time too. Kenya Revenue Authority’s (KRA) Pre-Arrival Clearance programme lets importers or clearing agents submit declarations and payments before the vessel docks. KRA recommends submitting at least 48 hours before arrival to maximize benefits.
Don’t forget the Advance Cargo Declaration (ACD). Kenya’s ACD system requires cargo details to be submitted and validated at least five days before vessel arrival. You’ll need to provide documents like the Bill of Lading, Commercial Invoice, Freight Invoice, and Export Declaration.
Customs classification questions can also slow things down. If an HS code raises doubts, customs must confirm the correct classification and duties before clearing your goods.
Regulatory requirements matter too. If your cargo needs a Pre-Export Verification of Conformity (PVoC), arriving without a Certificate of Conformity means inspections and testing at the destination. It pays to know KEBS requirements before shipping.
The best move? Start clearance before your shipment arrives. Hand over complete documents to your clearing agent early so customs can get cracking. Meet ACD deadlines, double-check your HS codes and product descriptions, and sort out KEBS or other regulatory needs before the goods ship.
Most importantly, know your shipping line’s demurrage and detention free periods: they rarely match KPA’s storage window. Don’t get caught off guard.
Clearing your cargo is just one part of the journey. Once unpacked, the empty container must be returned to the shipping line within the agreed free period.
If congestion or depot limits delay your return, detention charges will keep stacking up. Make sure you know exactly where and when to return the empty container before taking delivery.
Temporary relief measures have appeared during tough congestion spells, like the storage and demurrage waivers in late 2025, but these are exceptions, not the rule.
A smarter, more reliable strategy is to work backwards from the vessel’s arrival date: complete your ACD filing, submit customs documents early, resolve regulatory issues, and understand both KPA storage and your shipping line’s free-time terms.
Get ahead of the game. Early ACD submissions, thorough customs paperwork, clear product classifications, close collaboration with your clearing agent, and knowing your carrier’s free-time rules will guard your wallet from surprise charges.
