Shortened as D&D, demurrage and detention are often linked together when shipping. Let’s understand them in detail.

are additional surcharges, paid when you exceed the number of days allotted for use of the container – called ‘freetime’ or ‘free days’.

When your container arrives at the port, shippers must ensure that it is returned to the carrier within the assigned freetime. If they fail to do so, carriers or shipping lines (who own the container) collect a late fee, called demurrage and detention. It is charged on a per-day basis.

D&D charges are levied to compensate the shipping lines for extended usage of containers by shippers, avoid congestion in the ports, urge the shippers for faster turnaround times, and free up equipment quickly.

Now, most people confuse them as a single charge; however, both are separate costs that differ slightly. Here’s how:

Demurrage vs detention in container shipping

• Demurrage: Charge levied for use of container/s (usually full) inside the terminal beyond allocated free days – from when they’re unloaded from the vessel until picked up.
• Detention: Charge for use of container/s (usually empty) outside the terminal beyond allocated free days – from picking them up from the port to returning them back.

What causes demurrage and detention charges?

The primary cause for these surcharges is due to delays in shipping or supply chain. This can be caused by:

• Missing or incorrect documentation
• Bad weather
• Port congestion
• Unavailability of equipment (forklifts, trucks, chassis, etc.)
• Problems in customs clearance
• Cargo inspection
• Rolling of containers
• Inefficient cargo drop-off or pick-up
• Overstay at terminal or port
• Failure to adhere to agreed-upon timelines

Do note that demurrage and detention costs are present during both import and export.

Who is responsible for demurrage charges?

This depends on whether we’re considering the import/export scenario.

• When exporting, if the exporter fails to load the container into the vessel within the stipulated number of free days, the consignor/sender pays these charges.
• When importing, if the importer fails to pick up the container/goods within the allocated free days, the consignee/receiver is responsible for paying these costs.

Now, the main question is, do you need to pay extra D&D charges every time you import or export the cargo? Well, that depends on the freetime you have.

Shipping lines, carriers, and port authorities understand that unpacking freight and returning containers takes time. So, they allow shippers certain days to carry out these activities without levying any charges. These allocated days are called , free days, or simply, freetime.

On average, shipping lines offer 3-6 free days before detention and demurrage charges kick in.

When booking with Maersk Spot, we show you the number of free days (freetime) offered, along with the price details to maintain transparency.

Ideally, shippers should be able to pick up the containers, unpack cargo, and return empty containers back to the port – all within the allocated offered by the carrier. The problem starts when unexpected delays clog your supply chain, and you end up stretching beyond your allocated freetime.

If you are unable to return the container within the freetime allowed, you have to pay D&D charges. It can either be when:

• Your container took too long to be picked up from the port, i.e., demurrage charge.
• You took too long to return the container to the port, i.e., detention charge.

D&D charges vary by container size, type, and location, and are calculated on a tier-based structure depending on the number of days involved. Despite starting at relatively small amounts, as each pricing tier is reached, the per-day charge will increase, potentially leading to hefty costs.

How are D&D charges calculated?

Maersk demurrage and detention charges are calculated per day beyond the allocated free time.
