Three clocks, not one
Most importers think of demurrage as a single charge. It is usually three, running on separate clocks with separate free periods and separate owners. Demurrage is charged by the shipping line while the box sits inside the terminal. Detention is charged by the line once the box leaves the terminal and has not been returned empty. Terminal storage is charged by the terminal for the ground the box occupies.
They overlap, they start on different triggers, and a plan that fixes one can extend another. Pulling a container out of the terminal early to stop storage starts the detention clock. Holding it inside to avoid detention keeps storage running. The saving is in sequencing all three, not in optimising one.
The cost is decided before arrival, not after
By the time free time expires, almost every decision that mattered has already been taken. The document set was either complete or it was not. Duty funding was either arranged or it was not. A truck was either booked against a realistic date or it was not.
Work done in the week before arrival is cheap. The same work done while charges accrue costs the charges as well.
Where the days actually go
| Stage | What commonly adds days |
|---|---|
| Pre-arrival | Incomplete or inconsistent documentation discovered on arrival |
| Assessment | Duty funding not available on the day the assessment is raised |
| Examination | Cargo description that does not match what is in the box |
| Release | Line release and terminal release treated as one step when they are two |
| Haulage | Truck booked against an optimistic release date, then rebooked |
| Empty return | Depot acceptance not confirmed, so the box returns twice |
Watch the clock daily, not weekly
Free time is short enough that a weekly review is a review of charges that have already been incurred. Someone should know, every working day, how many days remain on each box and what the next action is.
That single discipline changes more than any negotiation after the fact. Lines and terminals apply their published tariffs; the leverage is in the days, and the days are gone by the time the invoice arrives.
Plan the empty return with the pick-up
Detention often outlasts the cargo. The box is unstuffed, the goods are delivered, and the empty sits at the consignee yard because nobody confirmed which depot would accept it, on what days, and in what condition.
Confirm the return depot and its acceptance conditions at the same time you book the collection truck. It costs nothing then, and it is the difference between a clean return and a second trip.
Reducing container cost: working checklist
- document set verified against the actual cargo before the vessel arrives
- free days confirmed per line and per box, in writing
- duty funding available on the day the assessment is raised
- release treated as two steps: line release and terminal release
- haulage booked against a realistic release date, with a rebooking plan
- daily visibility of remaining free days on every box
- empty return depot and acceptance conditions confirmed at collection
- one named person accountable for the next action on each container
Where delay usually develops
- documentation corrected after arrival rather than before
- duty funding arranged after the assessment lands
- line release obtained without terminal release
- trucking booked against an optimistic release date
- free-time clock reviewed weekly rather than daily
- empty return depot not confirmed before collection
What the principal should prepare
- the complete and consistent document set
- duty and charge funding, available on demand
- confirmed free-time terms per line
- a delivery address and receiving window that is actually available
What Vandyvah can coordinate

- release sequencing across line, terminal and authorities
- haulage scheduling against realistic release timing
- daily free-time tracking and exception escalation
- empty return and depot acceptance
