Containerisation's introduction has made it possible to change all-in flat rates with modulation according to size and the status of the boxes (FCL imports, transhipment, transit, reefers and so on). Consequently, container terminal tariffs became much more transparent than those for general cargoes. This simplification was, however, only short-lived. Their complexity started to increase in line with the ever-growing importance of container shipping. Moreover, in the past decade, the major restructuring both in container shipping and port handling, has lead to a situation in which established pricing principles have been seriously challenged.
