List of busiest container ports (Wikipedia)
https://en.wikipedia.org/wiki/List_of_busiest_container_ports
This article lists the world's busiest container ports (ports with container terminals that specialize in handling goods transported in intermodal shipping containers), by total number of twenty-foot equivalent units (TEUs) transported through the port. The table lists volume in thousands of TEU per year. The vast majority of containers moved by large, ocean-faring container ships, are 20-foot (1 TEU), and 40-foot (2 TEU) ISO-standard shipping containers, with 40-foot units outnumbering 20-foot units to such an extent, that the actual number of containers moved is between 55%–60% of the number of TEUs counted.
