⁉️ Demurrage vs. Detention:
Do you know the real difference?
In international logistics, these two terms are often used interchangeably, but they represent very different charges.
Mistaking one for the other can lead to costly surprises on your final invoice.
⬇️Here is the simplest way to distinguish them:
🔷Demurrage:
The container is INSIDE the terminal.
Think of it as a "Parking Ticket" for occupying port space beyond the free time.
🔷Detention:
The container is OUTSIDE the terminal.
Think of it as an "Equipment Rental Fee" for keeping the container in your possession too long.
Let’s look at two common scenarios:
① Import
▪️Demurrage: Your cargo has arrived at the port, but customs clearance is delayed or the trucker is late. If the container sits at the terminal past the free days, you pay Demurrage.
▪️Detention: You’ve picked up the full container and hauled it to your warehouse, but unloading takes too long. If you don't return the empty box to the depot in time, you pay Detention.
② Export
▪️Detention: You pick up an empty container to load at your factory. If you keep the box longer than the agreed free time before returning it to the port, you pay Detention.
▪️Demurrage: You’ve delivered the full container to the port, but it misses the vessel due to documentation issues. If it sits at the terminal waiting for the next ship, you pay Demurrage.
💡Core Principles:
🔹Demurrage = Container overstays INSIDE the terminal/depot.
It's a "parking ticket" for the port space.
🔹Detention = Container overstays OUTSIDE the terminal/depot.
It's a "borrowing fee" for holding the equipment too long.
⚠️ Storage is Different:
Don't confuse Demurrage with Storage Fees. While Demurrage is for the container use, Storage is for the physical space at the port.
