TEU (Twenty-foot equivalent unit). This is the space that would be occupied by a container having the international ISO standard external dimensions, one of which, the length, is 20 feet or 2.4 metres.
Tariff. This is the list of freight rates, surcharges and other charges and terms and conditions of carriage of goods. It can also be called the “rate book” and is generally published by a liner conference or even by independent liner operators.
