Demurrage
A penalty charge assessed when a shipping container, railcar, or trailer is not loaded or unloaded within the allotted free time at a port, rail terminal, or warehouse. In ocean freight, demurrage applies to containers sitting at the port terminal beyond the free days. It differs from detention, which applies to equipment held at the shipper's or receiver's location. Demurrage charges can escalate quickly, often increasing per day the longer the equipment is held.
Real-World Example
An importer's container sits at the Port of Savannah for 8 days because the warehouse is not ready to receive it. With 4 free days, the importer pays 4 days of demurrage at $150/day ($600).
Why Demurrage Matters for Shippers
Freight pricing is rarely straightforward. Knowing how Demurrage works gives you leverage when negotiating rates, helps you spot hidden fees on invoices, and allows you to budget more accurately. Shippers who understand pricing mechanics are better equipped to compare quotes apples-to-apples and avoid costly surprises at delivery.
Common Questions About Demurrage
How is Demurrage calculated in freight shipping?
Demurrage in freight is typically calculated based on a combination of distance, weight, freight class, equipment type, and current market conditions. Additional factors like fuel surcharges, accessorials, and lane-specific supply and demand also play a role. Ask your broker for a transparent rate breakdown.
Can I negotiate Demurrage with my carrier or broker?
In most cases, yes. Understanding how Demurrage is structured gives you the knowledge to negotiate effectively. Volume commitments, flexible pickup windows, and consistent lane history all strengthen your negotiating position.
How can I reduce costs related to Demurrage?
Start by understanding exactly what goes into Demurrage, then look for optimization opportunities: consolidating shipments, adjusting pickup/delivery windows, improving packaging to reduce freight class, or committing to consistent volumes. A good freight broker will help you identify these savings.
