Shipping Terminology

The following terms are common-place when shipping goods in containers.^[1]

Ocean Freight: The cost of actually shipping the container from A to B.
Bunker: The cost of the fuel for the ship.
Stuffing: Getting the goods into the container and sealing it. The details here are important as this may include moving the container around or not.
Lashing: Physically lashing the vehicles into the container so they don’t move around.
Unstuffing: Getting the goods out of the container, which again may include moving the container from the port to the yard or not.
Documentation Fee: The cost of lodging all the paperwork with customs.
Bill of Lading: The official document describing the contents of the container.
Port Fees: The amount charged by the port to allow the container and it’s contents to pass.

Notes:

All of the above may be charged per container or per vehicle and may cover both ends or not.
If you put more than one vehicle into a single container (it's usually cheaper) make certain it's very clear on the Bill of Lading who owns which vehicle.
