Last Free Day

Last Free Day (LFD) is the final calendar day an import container can remain at a marine terminal or on carrier equipment without incurring demurrage or detention charges. After the last free day passes, daily fees begin accumulating immediately. For importers managing multiple containers across different carriers and terminals, tracking LFDs is one of the most time-sensitive operational tasks in the import process.

How Last Free Day Is Calculated

LFD is determined by the ocean carrier’s tariff, which specifies the number of free days granted from a defined start date. The start date varies by carrier: some count from the vessel discharge date (when the container was unloaded from the ship), others count from the container availability date (when customs releases the container and it is physically accessible for pickup). The distinction matters because a container discharged on Monday might not be available until Wednesday if it is selected for a CBP examination or if the terminal needs time to move it to the pickup area.

Most carriers provide 3 to 5 free days for standard dry containers. Reefer (refrigerated) containers typically receive fewer free days (2 to 3) because they require electrical connections and consume terminal resources. Some carriers offer extended free time on specific trade lanes or to shippers with volume commitments.

Weekends and holidays are treated differently by different carriers. Some carriers exclude weekends and federal holidays from the free time calculation, effectively extending the pickup window. Others count calendar days straight through, including weekends. The carrier’s tariff is the definitive source for how free days are counted.

Why Missing the LFD Is Expensive

Demurrage charges activate the day after the LFD. At major U.S. ports, initial demurrage rates range from $100 to $200 per container per day and escalate on a tiered schedule. A container that exceeds its LFD by 10 days at the Port of Long Beach can accumulate $1,500 to $3,000 in demurrage from the carrier, plus separate terminal storage fees from the marine terminal operator. These are two different charges from two different entities, and importers often do not realize they are paying both.

For FBA sellers importing containers of inventory, demurrage costs eat directly into product margins. A $1,500 demurrage bill on a container holding 3,000 units adds $0.50 per unit to the landed cost. On a product with a $3.00 profit margin, that represents a 17% margin reduction from a single avoidable fee.

Monitoring LFD

Tracking LFDs requires checking carrier websites, terminal websites, or using a container tracking platform that aggregates this data. Each carrier publishes container availability and free time information through their online portals or via EDI messages. Freight forwarders and customs brokers typically monitor LFDs on behalf of their clients and send alerts when the pickup deadline approaches.

For importers handling five or more containers per month, manual tracking becomes unreliable. Missed alerts, outdated spreadsheets, or overlooked email notifications lead to missed LFDs. Automated tracking tools like Terminal49, project44, or FreightOS pull LFD data directly from carrier and terminal systems and send proactive notifications 48 hours before expiration.

Strategies for Meeting the LFD

File customs entries before the vessel arrives, ensuring the container is released as soon as it is discharged. Pay ocean freight invoices promptly so the carrier issues the delivery order without delay. Schedule drayage pickup for 1 to 2 days before the LFD, not on the LFD itself, to allow for trucker delays, terminal congestion, or gate closures.

If the warehouse is not ready to receive the container, execute a pre-pull to an off-dock yard or to the warehouse yard. This stops the terminal demurrage clock. The container then sits at the off-dock location at a fraction of the terminal cost while waiting for a dock door to open.

When LFDs are missed despite best efforts (due to customs exams, carrier system errors, or force majeure events), dispute the charges. Carriers have dispute processes, and the Federal Maritime Commission’s 2020 guidance supports reducing or waiving demurrage when the delay was not within the importer’s control. Document the cause of the delay thoroughly to support any dispute filing.
