Rank / Size of the 50 Largest Container Ports, 1980-2008 (TEUs)

While traffic handled by the largest container ports has surged, the emergence of mega container ports handling more than 5 million TEUs has been prevalent. As of 2008, 10 ports, almost all of them in Pacific Asia, handled more than 10 million TEU, clearly standing above all the others. There is thus a trend of traffic concentration taking place among the world's largest ports with two main groups. The first concerns 5 ports above 12 million TEUs and that are the world's main commercial platforms. They include Singapore, Shanghai, Hong Kong / Shenzhen and Busan. The second concerns 10 ports above 7 million TEUs.
