Detention
Container held outside the terminal past free time. Requires gate-out and empty-return dates.
This one runs on a clock
It accrues every day until something stops it, so the number of days matters as much as the rate. Two figures decide the total: when the clock started, and how many free days you had. Both should be on your arrival notice.
What it is calculated on
Per day, which is why the number of days matters as much as the rate.
What it appears as on real documents
Providers write the same charge many different ways. All of these mean this charge:
- detention
- detention charge
- container detention
- per diem
- equipment detention
- det
- container per diem
- equipment per diem
What settles it when you question it
The test is whether the amount matches what was quoted, on the same basis. If the basis changed, that is the thing to ask about rather than the total.
Ask for:
- Gate-out record
- Empty container return receipt
- Published daily rate schedule
- Line-by-line calculation breakdown
Before you book
This cannot be quoted in advance, because the amount is not your provider's to set. What you can pin down is how it will be billed and what evidence you will be given.
Ask: Ask for the free days for equipment, the daily detention rate, and the empty return location.
