Containerization is a system of freight transport based on a range of steel inter-modal containers (also ‘shipping containers’, ‘ISO containers’ etc). Containers are built to agreed upon standard dimensions and can be loaded and unloaded, stacked and transported efficiently over long distances, often by container ship, rail and semi trailer trucks without being opened. The system developed after WWII and led to greatly reduced transport costs and supported a vast increase in international trade.


The container, as the meaning implies, is the equipment used to store and carry goods. In shipping, the term was used to refer to any type of box used to carry cargo.
