Demurrage, Detention and Free Time: Plan the Days After Arrival

The arrival notice reaches the buyer on Friday. The warehouse's next unloading slot is Wednesday. The broker is waiting for a corrected document, and the trucker has not yet confirmed a pickup. The sea journey is almost over, but the shipment is not ready to move.

This is the point where a vague promise of “several free days” becomes unhelpful. The receiving team needs the actual dates, the applicable charges and the actions that stop each clock.

Understand the charge names, then check the local terms

In Maersk's published terms, demurrage concerns carrier equipment held inside the terminal, port or depot beyond agreed free time; detention concerns it outside. Combined arrangements can cover both periods. Storage can be a separate charge for using terminal or depot space. The carrier explains that the application depends on the relevant country arrangements.

Use those definitions as an introduction, not as a rate sheet for every shipping line. Ask your forwarder which tariff and booking conditions apply to this shipment. A terminal charge and a carrier charge may refer to related events without being the same invoice item.

Also clarify what a trucker's “detention” quotation means. It may concern vehicle waiting time rather than the carrier's container-equipment clock. The shared word is a good reason to ask who charges it, what triggers it and which document sets the rate.

Get the last free date in writing

Request the free-time allowance, the event that starts it, the counting method and the stated last free date. Ask whether the arrangement is separate or combined and whether weekends or holidays count. Do not work from a general statement made before the booking was confirmed.

Keep the evidence with the shipment file: booking conditions, written extensions and any carrier confirmation. Maersk provides booking-specific access to free days, last free dates and pickup or return locations. Other providers may use different systems, so identify where your team should obtain the current information.

If the sailing changes, check the dates again. An old screenshot may be accurate for the moment it was taken and still be unsafe to use as today's collection plan. Give one person responsibility for communicating the current dates to the broker, trucker and warehouse.

Separate release, availability and collection

Make a simple action list for the shipment: customs status, carrier or forwarder release, terminal availability, trucking appointment and warehouse acceptance. These are related steps, but a positive update on one does not prove the others are complete.

For example, the buyer may have supplied the broker with the invoice while the carrier is still waiting for release instructions. Or the cargo may be released while the warehouse has no available appointment. Ask for the status of the specific unfinished step instead of circulating the broad question “Is the container ready?”

For footwear, the warehouse may also want advance carton data or a delivery reference. Provide that information before asking the trucker to commit to a slot. If there are mixed models and size assortments, send the final packing list so the receiver can plan the work.

Calculate exposure without treating the illustration as a tariff

Suppose, purely for budgeting, that a particular charge begins after a confirmed last free day and the applicable rate for each of the next three chargeable days is USD 120. Three such days would cost USD 360. The calculation is simple; establishing the correct dates and rate is the harder part.

Real tariffs may have escalating bands, different equipment categories, minimums or separate charges. Use the actual booking and local terms. Do not multiply a rate from an old shipment by this shipment's delay and call that a verified invoice.

If the amount is uncertain, record a range with its assumptions and ask for confirmation. That lets the commercial team decide whether an extra unloading shift or another available delivery slot is worth considering. Compare confirmed alternatives rather than treating every operational inconvenience as cheaper than a possible charge.

The empty return needs its own plan

For a carrier-owned container, unloading the boots is not necessarily the final equipment step. Confirm where the empty container must be returned, who arranges the move and what evidence closes the return. Check the authorised return location before the truck departs.

Ask the warehouse how quickly it can unload and whether the truck is expected to wait or leave the container. If an appointment or depot issue prevents return, keep the dated instructions, attempted bookings and communications. An undocumented phone conversation is difficult to use later when reconstructing the delay.

Retain the relevant interchange or gate record with the shipment documents. It provides a much clearer end point than a message saying “container finished.” If the nominated location changes, confirm the revised instructions with the responsible provider rather than improvising a different depot.

Investigate an unexpected invoice with a timeline

Build the timeline before disputing the amount: availability, release, appointments, gate-out, unloading and return. Compare the billed dates and equipment number with the records. Ask the issuer to explain any mismatch and preserve evidence of an agreed extension or a blocked operation.

This does not mean every delay automatically entitles a party to a waiver. Entitlement and responsibility depend on the applicable contract, tariff, facts and local rules. Use the provider's dispute process and obtain specialist help for a material disagreement.

When comparing DAP and DDP offers, discuss exceptional costs and the parties' cooperation before shipment. A clear receiving plan is useful under either term. Our shipping document guide covers another common source of last-minute delay.
