Dwell Time


Dwell time is the amount of time cargo, containers, or transportation equipment spends sitting idle at a specific point within the supply chain, such as a port, terminal, or warehouse. It is a critical metric in logistics and supply chain management, as extended dwell times can lead to increased costs and inefficiencies.

Detailed Explanation

Dwell time is often used as an indicator of the efficiency of cargo movement through a supply chain. It begins when a container is unloaded from a ship, train, or truck and ends when it is picked up for the next leg of its journey.

Extended dwell times can be caused by various factors, including delays in customs clearance, inefficient terminal operations, lack of available transportation, or issues with cargo handling. High dwell times can lead to congestion in ports and terminals, increased demurrage and detention charges, and overall delays in the supply chain.

Managing and reducing dwell time is essential for logistics companies to maintain efficient operations, reduce costs, and meet delivery deadlines.

Strategies to reduce dwell time include improving coordination among supply chain partners, enhancing cargo tracking and visibility, and optimizing scheduling and resource allocation.


At a busy port, a container might experience extended dwell time due to a backlog in customs clearance, causing delays in the container’s journey to the warehouse.

A trucking company might face increased dwell times at a warehouse due to inefficient scheduling, resulting in trucks waiting for extended periods to load or unload cargo.

Frequently asked questions about dwell time

What impacts do high dwell times have on the supply chain? High dwell times can lead to increased storage and handling costs, congestion at ports or terminals, and overall delays in the supply chain.

How can companies reduce dwell time? Strategies include improving coordination and communication among supply chain partners, enhancing cargo tracking systems, and optimizing resource allocation and scheduling.

What is the difference between dwell time and demurrage? Dwell time refers to the period cargo or equipment is idle, while demurrage specifically refers to the charges incurred due to extended dwell time beyond an agreed-upon period.

Are there industry standards for acceptable dwell times? Acceptable dwell times can vary based on the type of cargo, mode of transport, and specific operational practices of ports or terminals.

Can technology help in reducing dwell time? Yes, technologies like real-time tracking systems, automated scheduling, and advanced analytics can help in identifying bottlenecks and reducing dwell time.

How does dwell time affect transportation costs? Extended dwell times can increase transportation costs due to additional storage charges, delayed deliveries, and inefficient use of resources.

Is dwell time a concern in all types of transportation modes? Dwell time is a concern in all modes, including sea, air, rail, and road transport, as it affects the overall efficiency and cost-effectiveness of the supply chain.
