What Is Demurrage? Container Charges, Detention, and Free Time<\/h1>\n

Demurrage is a charge that can apply when an import container remains at a marine terminal beyond its allowed free time. Detention generally applies when the carrier\u2019s container has been collected but is kept outside the terminal beyond the permitted period. Both can add to the cost of an international shipment.<\/p>\n

Before your container arrives, confirm how long you have to collect it, who is arranging delivery, and when the empty equipment must be returned. Keep those details with the shipment documents so your broker, freight forwarder, and trucking provider are working toward the same deadlines.<\/p>\n

This guide covers demurrage and detention for commercial container imports into the United States, including how charges are calculated, what to check on an invoice, and what to do when a container is already delayed.<\/p>\n

Demurrage vs. Detention vs. Storage<\/h2>\n

The charges on a container shipment can cover different periods and services. Start by identifying where the container was during the dates being billed and what the charge covers.<\/p>\n

\n
\n\n\n\n\n\n\n\n
Charge<\/th>\nWhat it generally covers<\/th>\nWhat to confirm<\/th>\n<\/tr>\n<\/thead>\n
Demurrage<\/strong><\/td>\nAn import container remaining at the marine terminal beyond its permitted free time.<\/td>\nThe container\u2019s availability, applicable free time, pickup date, and rate schedule.<\/td>\n<\/tr>\n
Detention<\/strong><\/td>\nUse of the carrier\u2019s container outside the terminal beyond the permitted free time.<\/td>\nThe collection date, return deadline, return instructions, and event that ends the charge.<\/td>\n<\/tr>\n
Terminal storage<\/strong><\/td>\nUse of terminal space, which may be charged separately or included within another charge, depending on the arrangements.<\/td>\nWhether storage is already included and which tariff or terminal schedule applies.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n

The Federal Maritime Commission\u2019s explanation of demurrage and detention<\/a> distinguishes time beyond free time at a marine terminal from extended use of the equipment. Carrier terms determine how individual charges are described and calculated.<\/p>\n

Some bookings use combined demurrage and detention<\/strong>, with one allowance covering the period from discharge through empty-container return. Under those terms, collecting the container does not start a separate allowance. Check the booking rather than assuming you have a fresh period of free time after pickup.<\/p>\n

Ask for clarification when an invoice uses an unfamiliar description. A charge labeled \u201cstorage\u201d should identify what was stored, where, for which dates, and under which terms.<\/p>\n

How Free Time and the Last Free Day Work<\/h2>\n

Free time is the period allowed before the relevant demurrage or detention charges begin. The last free day<\/strong>, often shortened to LFD, is the final day of that allowance. Confirm the applicable cutoff time and facility hours as well as the date.<\/p>\n

There is no single free-time allowance that applies to every U.S. container shipment. The carrier, terminal, equipment, and booking terms can affect the calculation. Even the event that starts free time can differ between locations. Maersk\u2019s U.S. import guidance<\/a>, for example, sets out different starting points at different terminals.<\/p>\n

Ask whether free time is counted in working days or calendar days, and how days are counted once that allowance expires. Some U.S. carrier tariffs use working days for free time but calendar days for charges after it ends. A weekend should not automatically be treated as two extra free days.<\/p>\n

Keep the collection deadline and empty-return deadline separate. Give both to the trucking provider, and check that the receiving facility can unload the container within the delivery arrangements.<\/p>\n

If the carrier and terminal show different dates, have the discrepancy resolved before relying on either one. Where additional free time has been agreed, keep the written confirmation and check which charge it covers.<\/p>\n

How Demurrage Charges Are Calculated<\/h2>\n

The applicable tariff or contract sets the daily rate and charging periods. Rates can differ by location and equipment type, and some schedules increase the daily charge as the delay continues. Carrier tariffs can also change, so use the schedule applicable to your shipment rather than a figure from an earlier import.<\/p>\n

For illustration, assume one container incurs five chargeable days after its free time expires. The first three days are charged at $150 per day, and the next two at $225 per day.<\/p>\n

\n
\n\n\n\n\n\n\n\n
Chargeable period<\/th>\nDays<\/th>\nIllustrative daily rate<\/th>\nSubtotal<\/th>\n<\/tr>\n<\/thead>\n
First three days<\/td>\n3<\/td>\n$150<\/td>\n$450<\/td>\n<\/tr>\n
Next two days<\/td>\n2<\/td>\n$225<\/td>\n$450<\/td>\n<\/tr>\n
Total<\/strong><\/td>\n5<\/strong><\/td>\n<\/td>\n$900<\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n

These are hypothetical rates used to explain the calculation. They are not an A1 quote or a published carrier tariff.<\/em><\/p>\n

Check the calculation for each container. Confirm the free-time allowance, the specific chargeable dates, and whether the correct rate tier was applied.<\/p>\n

Ask what other charges remain outside that calculation. For example, a demurrage payment may not cover separately billed storage or equipment-related services. The relevant terms should explain what is included.<\/p>\n

Who Pays Demurrage and Detention?<\/h2>\n

Start with the transport booking, bill of lading, and agreements for the shipment. Ask the company issuing the invoice to identify the basis for charging your business. For invoices covered by the FMC\u2019s billing rules, that explanation is part of the required invoice information.<\/p>\n

Before accepting a supplier\u2019s freight arrangement, ask who will handle destination charges, customs clearance, pickup, and empty return. Record those responsibilities alongside the agreed price.<\/p>\n

A delay involving several companies also needs to be examined before assigning responsibility. Establish what each party was asked to do, when it received the necessary information, and what prevented the next step.<\/p>\n

Older summaries of U.S. billing rules need care. The provision that restricted who could receive a demurrage or detention invoice was set aside in 2025. The FMC confirmed that the remaining invoice-content and billing requirements continued to apply.<\/p>\n

How to Reduce Avoidable Demurrage and Detention<\/h2>\n

Arrange Customs Clearance Before Arrival<\/h3>\n

Give your broker the available commercial invoice, packing list, transportation details, and product information while the shipment is being prepared or is still moving. Ask what remains outstanding and who needs to supply it.<\/p>\n

Keep your supplier involved until document questions have been answered. Where the broker needs a clearer product description or supporting information, obtain that directly rather than forwarding the same incomplete document again.<\/p>\n

Our guide to the U.S. customs clearance process<\/a> explains the preparation, entry, and release stages.<\/p>\n

At A1 Worldwide Logistics, the account-opening process includes approving the quote and signing a power of attorney before the assigned broker starts working on your behalf. Allow time for that setup rather than leaving the first conversation until the container has reached its last free day.<\/p>\n

Confirm Pickup and Unloading Arrangements<\/h3>\n

Customs release is one of the checks needed before collection. Carrier release, terminal availability, pickup appointments, and transport arrangements can still affect when the container leaves the port. Our guide to what happens after a container arrives at the port<\/a> explains those stages.<\/p>\n

Arrange the receiving appointment alongside the pickup. Give the trucking provider the delivery address, opening hours, access restrictions, and unloading requirements.<\/p>\n

Check how long unloading is expected to take and whether the necessary staff and equipment will be available. A container should not be collected for a delivery appointment that the receiving facility cannot accommodate.<\/p>\n

Include Empty Return in the Delivery Plan<\/h3>\n

Confirm who is responsible for returning the empty container, where it must go, and whether an appointment is required. Ask for confirmation once the return has been completed and retain the gate-in or equipment-interchange record.<\/p>\n

For carrier-arranged delivery, check whether you must notify the carrier that the container is empty and ready for collection. Some delivery terms use that notification when determining the end of the detention period.<\/p>\n

A1\u2019s trucking and container drayage services<\/a> include port pickup and inland transportation. When requesting a quote, explain whether you need the full container delivered, cargo collected from a container freight station, or another delivery arrangement.<\/p>\n

What to Do When a Container Is Already Delayed<\/h2>\n

Ask your broker or forwarder to identify the specific obstacle. The shipment may be awaiting customs release, carrier documentation, terminal availability, payment, or a pickup arrangement. Establishing which party needs to act gives you a useful starting point.<\/p>\n

Request the current last free day, charges accrued so far, the applicable daily rate, and the next required action. Give the person handling the delay any information you can supply immediately.<\/p>\n

Keep efforts to release, collect, or return the container moving while a billing question is being reviewed. Ask the billing party to confirm whether charges are continuing and whether any extension or waiver has been approved.<\/p>\n

Can Demurrage Apply During a Customs Hold?<\/h3>\n

A customs hold does not automatically stop demurrage or guarantee that every resulting charge is valid. The FMC\u2019s guidance on government inspections and container availability<\/a> considers the circumstances and whether the charges serve their intended purpose of encouraging cargo movement.<\/p>\n

Ask your broker to explain the hold and any outstanding requirement. Keep the relevant notices, requests for information, and release confirmations, including their dates.<\/p>\n

If the shipment is awaiting documents, obtain the specific information requested. If it is awaiting an examination or agency decision, ask what the next step is and who is handling it. Our guide to a shipment stuck at Customs<\/a> covers clearance-related problems in more detail.<\/p>\n

The broker can help with the clearance work, but a demurrage waiver needs to be addressed with the party billing the charge.<\/p>\n

What Happens When an Empty Container Cannot Be Returned?<\/h3>\n

Keep a dated record of the return instructions and each unsuccessful attempt to arrange or complete the return. Save appointment-system screenshots, rejection messages, and communications identifying any alternative location offered.<\/p>\n

These circumstances can be relevant when charges are reviewed. In a July 2026 update, the FMC described a court decision upholding its finding that detention charges were unreasonable during a three-day closure when the trucker had no practical ability to return the equipment beforehand. That decision concerned the facts of that shipment, rather than a blanket exemption for every weekend or closure.<\/p>\n

How to Check and Dispute a Demurrage Invoice<\/h2>\n

Start with the shipment records and the invoice. Identify the specific dates, rates, or requirements you believe are incorrect so the billing party can review a defined issue.<\/p>\n

Check the Invoice Details<\/h3>\n

For covered U.S. invoices, the FMC\u2019s invoice-content requirements<\/a> include container and bill-of-lading details, free-time dates, import-container availability, the dates charged, the applicable rate basis, and dispute contact information.<\/p>\n

Compare those details with your booking, terminal records, and collection or return confirmations. Check that any agreed free-time extension has been applied.<\/p>\n

Where you are disputing a lack of appointments, keep evidence from the period when you were trying to collect or return the equipment. Follow the billing party\u2019s documentation requirements. For example, Maersk asks for dated screenshots when a dispute concerns unavailable terminal appointments.<\/p>\n

Check the Billing and Dispute Deadlines<\/h3>\n

Under the FMC\u2019s invoice-issuance rules<\/a>, vessel-operating carriers and marine terminal operators must issue covered invoices within 30 calendar days of the date the charge was last incurred<\/strong>.<\/p>\n

For a non-vessel-operating common carrier, or NVOCC, the deadline is 30 calendar days from the issuance date of the demurrage or detention invoice it received<\/strong>. That calculation starts from the underlying invoice\u2019s issuance date, not the date the NVOCC received it.<\/p>\n

The billed party must be allowed at least 30 calendar days from invoice issuance<\/strong> to request mitigation, a refund, or a waiver. The billing party must attempt to resolve the request within 30 calendar days of receiving it, unless both parties agree to a later date.<\/p>\n

Check the payment due date separately. The period for submitting a dispute should not be treated as an automatic payment extension.<\/p>\n

Submit a Specific Request With Supporting Records<\/h3>\n

Include the invoice number, container number, dates being challenged, the reason for the request, and the supporting documents. State whether you are requesting a corrected calculation, a reduction, a waiver, or a refund.<\/p>\n

The FMC rules provide that certain failures, including missing required invoice information or missing the applicable issuance deadline, can eliminate the obligation to pay the affected charge. Verify the relevant facts and raise the issue in writing rather than simply leaving the invoice unanswered.<\/p>\n

When the matter remains unresolved, the FMC\u2019s complaints and assistance services<\/a> explain the available routes, including dispute-resolution assistance and charge complaints. The appropriate route depends on the billing party and the issue.<\/p>\n
