What Is Demurrage?
Learn how demurrage charges apply when cargo is not collected from ports or containers are not returned within the free time period.
Key Takeaways
- Demurrage is a penalty charged when cargo remains at a port or terminal beyond the allotted free time after vessel arrival.
- Charges escalate daily and can quickly exceed the value of the cargo itself for prolonged delays.
- Efficient customs clearance and documentation preparation are the best defences against demurrage costs.
What Demurrage Is
Demurrage is a charge levied by shipping lines or terminal operators when a container or cargo remains at the port beyond the agreed free time period after a vessel's arrival. Free time, typically three to seven days, allows the consignee to arrange customs clearance and collect goods. Once free time expires, daily demurrage charges begin accruing. These charges compensate the terminal for occupied space and the shipping line for the use of their container equipment beyond the agreed period.
Demurrage vs Detention
While often confused, demurrage and detention are distinct charges. Demurrage applies while the loaded container sits at the port terminal. Detention applies after the container has been collected from the port but not yet returned empty. In practice, a shipment to Lagos might incur five days of demurrage waiting for customs clearance at Apapa, then three days of detention while the importer unpacks goods at their warehouse. Both charges accumulate daily and are billed by the shipping line.
How Demurrage Charges Accumulate
Demurrage rates escalate in tiers. A typical structure might charge $75 per container per day for the first five days beyond free time, $150 for the next five days, and $250 thereafter. For a 40-foot container delayed 15 days beyond free time, charges could reach $2,375. At congested African ports, where clearance delays are common, demurrage costs frequently exceed $5,000 per container. For businesses importing low-margin goods, these charges can wipe out profitability on an entire shipment.
Minimising Demurrage Costs
Prevention starts before the vessel arrives. Pre-clear documentation with customs to enable immediate processing upon arrival. Ensure all duties, taxes, and fees are ready for payment. Maintain good relationships with customs brokers who can expedite clearance. Negotiate extended free time with shipping lines, especially if you are a regular shipper. Monitor vessel arrival schedules to prepare in advance. When delays are unavoidable, communicate promptly with the shipping line, as some offer grace periods or reduced rates for documented customs delays.
