A system of standardized transport that uses large steel boxes to ship goods, greatly impacting global trade. These boxes, typically 20 or 40 feet long, can be easily transferred between ships, trains, and trucks. As an example, produce grown in South America might be packed into these units, shipped to Europe, then transferred to trucks for distribution across the continent.
This process revolutionized shipping by significantly reducing the time and cost associated with loading and unloading cargo. Its adoption facilitated increased efficiency, leading to a massive expansion of international commerce. The historical context involves its widespread acceptance in the latter half of the 20th century, transforming port cities and global supply chains. It has also profoundly altered the geography of economic activity by concentrating it in areas with access to efficient transportation networks.
