Every import container arrives with an invisible countdown attached. Manage it and drayage stays a predictable line item; ignore it and charges compound daily. That countdown is the last free day, and no metric matters more to your landed cost per container.

What the last free day actually is

When a container discharges from the vessel, the marine terminal grants a window of free time — a set number of days the box can sit at no charge. The last free day (LFD) is the final day of that window. From the next day forward, the terminal bills demurrage daily, often on an escalating scale.

Free time varies by terminal, ocean carrier, and service contract. Weekends and holidays may or may not count. And critically, free time can shrink in practice: if the terminal has no appointment slots before your LFD, the deadline doesn’t move — you do.

The three clocks every importer should separate

Shippers often lump these together; carriers bill them separately:

Demurrage (terminal clock)

Charged by the terminal while the loaded container sits inside the port past free time.

Per diem / detention (equipment clock)

Charged by the ocean carrier for keeping their container out in the field past equipment free days — even if it’s sitting empty at your dock.

Driver detention (dock clock)

Charged by the drayage carrier when a driver waits at your facility beyond free minutes.

An LFD strategy that solves clock #1 by pulling the box early still needs a plan for clock #2 — return the empty promptly.

How to track your LFD without spreadsheet pain

1. Get the LFD at discharge, not at booking. Vessel delays shift everything; confirm free time once the container is actually on the ground.
2. Watch terminal appointment availability. An LFD three days out means nothing if the earliest pickup slot is four days out. Your dray carrier should flag this gap the moment it appears.
3. Use live tracking. Every container we handle is visible through the shipment tracker, backed by our Go Truck Hub TMS, so LFD exposure is never a surprise.
4. Set the dispatch trigger early. Best practice in Miami: book the dray as soon as the vessel has an ETA, and have the carrier chase the release. Same-week scrambles are where demurrage happens.

What to do when you can’t deliver before the LFD

The answer is almost always a pre-pull: your carrier pulls the container to a secure yard before the LFD, stopping the terminal clock, and delivers when your dock is ready. Yard storage costs a fraction of demurrage. Our 5-acre facility minutes from PortMiami stages 450+ containers exactly for this — see yard storage.

If the cargo needs devanning or palletizing anyway, route it through the container freight station during the staging window — you turn a cost-avoidance move into a value-added one.

Why asset-based carriers win the LFD game

Beating an LFD requires four things on the same day: a truck, a driver with terminal access, a chassis, and somewhere to put the box. Brokers assemble those from four vendors; an asset-based carrier owns the stack. That’s the structural reason our container drayage operation catches deadlines that brokered moves miss — and why the savings show up on your demurrage line, not ours.

Frequently asked questions

How many free days do containers get at the terminal?
It varies by terminal, carrier, and contract — commonly a handful of business days from discharge. Confirm your specific free time on every shipment rather than assuming a standard.

What happens if I miss my last free day?
The terminal begins charging demurrage daily, often at escalating rates, until the container is picked up. A pre-pull to a commercial yard is the standard way to stop the bleeding.

Does the last free day change if the terminal has no appointments?
Generally no — the LFD stands even when pickup slots are scarce, though some terminals or carriers may grant extensions in documented congestion events. Plan pickups early rather than relying on relief.
