What is Demurrage in Freight?

What Does Demurrage Mean in Shipping?

Demurrage is the fee charged for a container occupying terminal ground space after its free time expires — free time being the agreed period following discharge during which the box sits at the terminal at no cost. Container demurrage sits alongside detention, storage, and pre-pull charges in the freight and road transport terms that appear on European import invoices.

The word comes from the French verb demeurer, meaning "to remain." It entered shipping through maritime charter law, where it described compensation owed to a shipowner when a chartered vessel was held past its agreed loading or discharge window. Container shipping narrowed the term to terminal ground space.

The charge runs from the Last Free Day — the final calendar date inside the free time period. The container clears the terminal gate on or before that date. Demurrage starts the following day when a collection booked for the Last Free Day falls through, whether the warehouse appointment was missed or a chassis was unavailable.

What Triggers a Demurrage Charge?

Four conditions produce demurrage on European import shipments: a customs clearance delay, incorrect or incomplete shipping documentation, a warehouse unable to receive the container inside the free time window, and a chassis shortage at the terminal blocking collection.

• Customs holds are the most disruptive trigger. A container flagged for physical inspection stays at the terminal until the inspection closes and clearance is confirmed in writing.
• Documentation failures create a separate hold. A missing original bill of lading, an incorrect HS code on the import declaration, or a mismatch between the commercial invoice and packing list each stop customs release. Free time days disappear while the corrected paperwork moves through processing.
• Warehouse unavailability is operational. A cleared container ready for collection stays at the terminal when the destination warehouse has no delivery appointment open inside the free time window.
• Chassis shortages are mechanical. A drayage carrier holding a confirmed gate booking cannot execute it without a frame to carry the container. Chassis pools at high-volume terminals run short during peak import periods, and containers waiting on equipment accumulate demurrage while alternative frames are sourced.

How is Demurrage Calculated?

Demurrage accumulates as days beyond free time multiplied by the daily rate, multiplied by the number of containers held. The shipping line sets the daily rate in the bill of lading. Rates vary by terminal, trade lane, and container size — a 40ft box is rated higher than a 20ft box.

Shipping lines apply tiered rates rather than a flat daily figure. Days 1 to 4 beyond free time carry the lower charge. From day 5, the rate steps up. A third tier applies past day 10 on several major carriers. A container held 14 days past free time escalates through each tier as it sits — it does not accumulate at the day-one rate throughout.

The stacking effect hits multi-container shipments hardest. Eight containers each held six days past free time means eight boxes crossing at least one tier escalation, multiplied across six days. Demurrage invoices on mid-size commercial consignments reach five figures before collection happens.

Rate schedules are contractual and differ by carrier. Request the demurrage schedule from the shipping line at the point of booking, not after the invoice lands.

What is the Difference Between Demurrage and Detention?

Demurrage and detention are two separate charges at two different locations, billed by different parties. Demurrage covers a container held at the terminal past free time and is charged by the shipping line or terminal operator. Detention in freight covers the carrier's equipment — container or chassis — held at the importer's or exporter's premises past the agreed return period, and is charged by the carrier.

Both charges apply to the same shipment when a container is collected late from the terminal and then held at the warehouse before the empty box is returned. Each is calculated independently, and the grounds for disputing one do not carry over to the other.

How Does Drayage Timing Prevent or Trigger Demurrage?

Drayage is the physical move that removes the container from the terminal and stops the demurrage clock. A drayage in freight shipping booking executed before the Last Free Day prevents the charge from starting. A late collection means the container stays, free time expires, and demurrage accrues daily.

The collection sequence runs in a fixed order: customs clearance confirmed, warehouse delivery appointment confirmed, drayage truck booked with a terminal gate slot, collection executed on or before the Last Free Day. Each step depends on the one before it. A truck booked before customs clears achieves nothing — the terminal releases no container without confirmed clearance. A truck booked without a warehouse slot arrives at the gate with nowhere to deliver.

Go Trans arranges inland road distribution after container arrival at Belgian ports, coordinating the handoff between port release and the first inland delivery point through carrier partners. Consignments continuing beyond the warehouse move under freight services across Europe as dedicated truckload or groupage, matched to load size.

How Can Importers Avoid Demurrage Charges?

Four actions taken before vessel arrival remove demurrage exposure: book the drayage truck before the vessel berths, monitor customs status from five days ahead of ETA, confirm the warehouse delivery appointment alongside the truck booking, and identify a backup chassis source at the terminal.

• Collection slots at busy terminals tighten within hours of discharge. A truck booked five days ahead of the estimated discharge date holds a confirmed queue position. A booking placed the day after discharge competes against every importer whose containers came off the same vessel.
• Customs monitoring from five days before ETA leaves room to correct a documentation problem before free time starts running. The same problem caught on day 3 of a 5-day window leaves no recovery time.
• Warehouse and truck appointments require confirming together. A terminal gate slot with no matching delivery window achieves nothing — the container clears the gate and then has nowhere to go.
• Chassis contingency matters at Antwerp-Bruges and Zeebrugge during peak periods. Identifying secondary chassis pool operators before a collection is scheduled removes equipment shortage from the trigger list.

Can a Demurrage Charge Be Disputed?

Three grounds support a formal demurrage dispute: a terminal calculation error on the free time start date, a force majeure event named in the bill of lading, and an incorrect container reference on the invoice.

• Calculation errors occur when the free time start date on the invoice does not match actual vessel discharge. Discharge dates are verifiable against terminal records and the shipping line's arrival notification. An invoice applying free time from an earlier date overstates the charge, and the correction is documented rather than argued.
• Force majeure clauses differ between shipping lines. Some name port strikes, terminal closures, or severe weather as grounds for suspending free time. Customs holds and warehouse issues sit outside these clauses on standard bills of lading — both are treated as the importer's operational risk. Check the clause wording before filing on this basis; the event type must be named explicitly.
• An incorrect container reference is a billing error. Where the invoice lists container numbers that do not match the boxes actually delayed, the invoice is wrong on its face.

Disputes go in writing, quoting the bill of lading number and the affected container numbers, with supporting documents attached. Shipping lines set a dispute window of 14 to 30 days from invoice date. Filed after that window, a dispute is rejected without review. Dispute rights are governed by the contract terms in each bill of lading.
