LFD stands for Last Free Day — the last day you can pull your container out of the terminal, or return the carrier's empty equipment, before per-day charges start stacking up. It's the single most important date attached to any container, and one of the most commonly blown — usually not because someone forgot, but because nobody was tracking it.
What "Free Time" Actually Means
When your container is discharged from the vessel, the ocean carrier and the marine terminal give you a window of free time — a set number of days to get the box moved at no storage cost. The Last Free Day is simply the last day of that window. Move the container by then and you owe nothing extra. Miss it and the meter starts.
Free time is often four to five days, but it is not a fixed number. It varies by carrier, by port, and by your specific freight contract. Some carriers count calendar days; others count business days and skip weekends and holidays. That one difference can move your LFD by two or three days — which is exactly why you confirm the date for each shipment instead of assuming it.
There Are Actually Two Last Free Days
This is where importers get tripped up. "LFD" can point to two different deadlines, tied to two different charges:
- The demurrage LFD — the last day to remove your full container from the terminal before demurrage begins. This is the LFD most people mean.
- The detention deadline — once you've picked the box up, the last day to unload and return the carrier's empty container and chassis before detention (also called per diem) begins.
Blow the first and you pay demurrage to the terminal. Blow the second and you pay detention to the carrier. Same root cause both times: the pickup and the empty return weren't staged around the deadlines.
Where to Find Your LFD
Your Last Free Day isn't hidden — it's published, you just have to go get it:
- The carrier's arrival notice (the notice of arrival) usually states the free time and the last free day for the shipment.
- The marine terminal's website lets you look up any container by its number and see its availability status and the LFD directly.
- Your freight forwarder or customs broker tracks it for you — but only if you've asked them to flag it, and only once customs has released the shipment.
That last point is the trap. A container can't leave the terminal until it is both available (discharged and released by the terminal) and customs-cleared. If your entry is held up — a missing document, an exam, unpaid duty — the LFD keeps ticking anyway. Free time does not pause for your paperwork.
What Happens After the Last Free Day
Once the LFD passes, storage charges begin — and they rarely stay flat. Most terminals and carriers escalate the rate in tiers: the longer the box sits, the higher the per-day charge climbs. A container that cost nothing to move on day five can quietly reach four figures by day ten, multiplied across every box in the shipment. For how those fees are structured — and the billing rule that can wipe them out when the delay wasn't your fault — see our breakdown of demurrage and detention.
How to Beat the Clock
Avoiding LFD charges is almost entirely about acting before the deadline, not reacting after it:
- Pre-file your customs entry so the shipment clears and releases the moment it's available — not scrambling on day four.
- Confirm the exact LFD in writing as soon as the arrival notice lands, and ask whether it's counted in calendar or business days.
- Pre-book drayage, a chassis, and a warehouse appointment ahead of the LFD. The drayage move is often the real bottleneck — trucker and chassis shortages can eat your free time on their own.
- Track both deadlines for every container — the demurrage LFD and the empty-return date — in one place, so nothing slips through.
The Bottom Line
The Last Free Day is a deadline the carrier and terminal hand you the moment your container hits the ground. Treat it as the anchor of your entire port-side plan: know it, confirm it, and stage every move — clearance, pickup, unload, empty return — to land ahead of it. Importers who track the LFD on every box almost never pay a storage charge. The ones who don't find out it existed when the invoice arrives.
This is general operational guidance, not legal or contractual advice. Free-time terms, day-counting rules, and demurrage and detention charges vary by carrier, terminal, and contract — confirm the specifics for your shipment with your freight forwarder or customs broker.
