What is Free Detention and Free Demurrage?

• Free Detention

The time the containers spend outside the terminal. Measured between picking them up at the port when they’re full and returning them to the port or a depot when they’re empty. For an importer, this is usually the time to unpack.

• Free Demurrage

The time the filled containers spend inside the terminal. This is measured from when they are offloaded from the vessel or train until they are picked up at the port (gated out).
