Ask anyone on an ocean import desk which date they watch most closely and most will say the LFD. It is the date that decides whether a container costs nothing extra or starts running up charges every day it stays in the terminal.
This guide explains what LFD means, how it is set, why it moves, where to find it, and how ops teams keep track of it across hundreds of containers.
What does LFD mean in shipping?
Direct answer: LFD stands for last free day. It is the final day a full import container can be picked up from the terminal without demurrage or storage charges. The free time before it is set by the carrier's and terminal's tariffs. From the day after the LFD, charges accrue per container per day.
You will see LFD on arrival notices, terminal availability screens and carrier portals. It applies container by container, so two containers on the same bill of lading can have different LFDs if they are discharged or made available on different days.
How is the last free day calculated?
The LFD is the end of a free-time window. How that window is counted depends on the terminal and carrier, but the pattern is similar:
- The start. Free time usually starts when the container is discharged from the vessel or becomes available for pickup.
- The length. The number of free days is set in the carrier's or terminal's tariff, or in your service contract if you negotiated more.
- What counts. Some tariffs count calendar days, others exclude weekends or public holidays.
So the LFD is not known for certain until the container is discharged. Any date you see before that is an estimate based on the expected arrival.
LFD, free time and detention free time: what's the difference?
| Term | What it covers | What happens after it |
| Free time | The days a container can stay in the terminal at no charge | Demurrage or storage starts |
| Last free day (LFD) | The final day of that free time | Charges start the next day |
| Detention free time | The days the container can be out of the terminal before the empty must be returned | Detention or per diem starts |
The LFD is about getting the full container out of the terminal. Detention free time is about getting the empty back. Both are tracked per container, and missing either one costs money. Our guide to demurrage charges covers the charges in detail.
Why does the last free day change?
This is what catches teams out. The LFD you planned around last week may not be the LFD today. Common reasons:
- The vessel arrives early or late, so discharge, and with it the start of free time, moves.
- Discharge takes longer than expected, so containers on the same vessel become available on different days.
- The terminal changes availability, for example after a closure, congestion or a change in operating hours.
- Holds are placed or lifted. A customs or freight hold usually does not stop the free-time clock, but it does stop you from picking up.
Each change arrives in a different place: a carrier email, a terminal website, a portal notification. That is why LFD tracking fails when it depends on someone remembering to check.
Where can you find the last free day?
- The arrival notice often shows an estimated LFD or free time, based on the expected arrival.
- The terminal's website or portal shows the confirmed LFD once the container is discharged and available.
- The carrier's portal may show free time and demurrage status for its containers.
For planning, treat the terminal's confirmed date as the one that counts, and recheck it whenever the ETA or availability changes.
What happens if you miss the last free day?
From the day after the LFD, the carrier or terminal starts charging demurrage or storage for each day the container remains. Rates often increase the longer the container stays, and the charge usually ends up with the importer, passed through by the forwarder or NVOCC.
Missing the LFD can also cause knock-on problems: the pickup has to be rebooked, the delivery date moves, and the customer's warehouse plan changes. The cost is often more than the charge itself.
How do ops teams keep track of the last free day?
A simple daily routine prevents most missed LFDs:
- Record an estimated LFD for every container as soon as the arrival notice comes in.
- Replace it with the confirmed LFD once the container is discharged and available.
- Re-check whenever the ETA, discharge or availability changes.
- List every container within two days of its LFD without a release or pickup appointment, and act on that list first.
- Tell the customer the LFD and what you still need from them, in the arrival notice and again when it changes.
The routine is easy to describe and hard to keep up by hand. A team handling hundreds of containers a month cannot open every terminal portal every day. That is where automation earns its keep.
How can AI help monitor the last free day?
An AI teammate can read carrier updates and arrival notices as they arrive, keep the ETA and LFD current on each shipment, and flag containers approaching their LFD that are still missing a release, a payment or a pickup plan. Instead of checking portals, the operator starts the day with a short list of containers that need a decision. We explain the approach in more detail in how AI automates container tracking and exception monitoring.
Where NavLogic fits
NavLogic is the AI teammate built for freight operations. For ocean imports it monitors ETA and last free day throughout transit and at the terminal, alongside holds, gate-out and empty return. When a container is at risk, it brings the issue to the right operator with the shipment context attached, so the decision happens while there is still time.
Frequently asked questions
What does LFD stand for in shipping?
LFD stands for last free day: the final day a full import container can be collected from the terminal before demurrage or storage charges begin.
Does the last free day include weekends?
It depends on the terminal's and carrier's tariffs. Some count calendar days, including weekends and holidays, while others exclude them. Always check the terms for the specific terminal and carrier.
Can the last free day be extended?
Sometimes. Extra free time can be negotiated in a service contract, and carriers or terminals may extend it in specific situations, such as terminal closures. Ask before the LFD passes rather than after.
Is the last free day the same as free time?
Not quite. Free time is the whole window of days at no charge. The last free day is the final day of that window.
Who sets the last free day?
The terminal and the ocean carrier set free time through their tariffs, and the LFD follows from when the container is discharged or becomes available. Service contracts can change the number of free days.
What is the difference between LFD and detention free time?
The LFD is the deadline for picking up the full container from the terminal. Detention free time is the separate window for returning the empty container after pickup. Missing the first leads to demurrage; missing the second leads to detention.
