Insights · Data · Busiest ports
A handful of Asian mega-hubs move a staggering share of the world's containers. In 2024 Shanghai became the first port ever to pass 50 million TEU in a single year — and the gap to the rest of the field tells you a great deal about how global trade is wired.
Shanghai is the busiest container port in the world. In 2024 it handled 51.5 million TEU, becoming the first port in history to cross the 50 million mark in a single year. That figure is so large it is hard to picture: it is more containers than the next two ports combined could have moved a decade ago, all funnelled through a single estuary system at the mouth of the Yangtze.
The story of the busiest ports is, in short, the story of Asian — and overwhelmingly Chinese — manufacturing reaching the rest of the world. The top of the table is a cluster of giant transhipment and export hubs, and the leaders elsewhere sit some distance behind. Below, we set out the 2024 numbers, explain how port size is actually measured, and show how you can see which ships are calling at any of these ports in the Marifest registry.
Container ports are ranked by throughput in TEU — twenty-foot equivalent units. A TEU is the standard yardstick of container volume: one ordinary 20-foot container is one TEU, and a 40-foot container counts as two. A port that handles "51.5 million TEU" has moved that many twenty-foot container-equivalents across its quays in a year, whether loaded for export, unloaded for import, or transhipped from one ship to another.
That measure is the right one for boxships, but it is not the only way to size a port. Ports can also be ranked by total cargo tonnage, which folds in bulk commodities — iron ore, coal, crude oil, grain — that never travel in containers at all. The two rankings can diverge sharply. Ningbo-Zhoushan is a clear example: third in the world by container TEU, yet among the very largest ports anywhere by total cargo tonnage, because it also handles enormous volumes of dry and liquid bulk. When you read a "busiest port" headline, it is always worth asking which measure it is using.
By container throughput, the 2024 podium is unmistakable:
| Rank | Port | Country | 2024 throughput (TEU) |
|---|---|---|---|
| 1 | Shanghai | China | 51.5 million |
| 2 | Singapore | Singapore | 41.1 million |
| 3 | Ningbo-Zhoushan | China | 39.3 million |
Shanghai sits clearly ahead at 51.5 million TEU, its record-breaking year confirming a lead that has held for well over a decade. Singapore takes second place with 41.1 million TEU — an all-time high for the city-state, whose port is built almost entirely on transhipment: containers arrive on one ship and depart on another, with Singapore acting as the great pivot of east-west trade. Ningbo-Zhoushan rounds out the top three at 39.3 million TEU, a vast multi-purpose complex on China's eastern coast that, as noted above, is even more dominant when bulk cargo is counted.
The figures here follow DNV's 2025 container-port ranking and Upply's 2024 ranking. Further down the table, Rotterdam leads Europe and Busan leads Korea — both well behind the Asian mega-hubs, and both important regional gateways rather than rivals for the top spots.
The concentration at the top is not an accident. Three forces push it. First, manufacturing geography: China alone produces a large fraction of the world's containerised exports, and those boxes have to leave through a handful of deep-water gateways close to the factories. Second, transhipment: ports such as Singapore and Shanghai are not just origin and destination points but switching yards, where cargo from many smaller feeder ports is consolidated onto the largest ocean-going ships. A single container can be counted as it arrives and again as it departs, which is one reason transhipment hubs post such high TEU totals.
Third, scale begets scale. The biggest container ships — now well over 20,000 TEU — can only call efficiently at ports with the deepest berths, the tallest cranes and the most automated yards. Those ports attract the largest carriers, which in turn justifies further investment in capacity. The result is a self-reinforcing cluster of Asian mega-ports that European and American gateways, hemmed in by smaller hinterlands and older infrastructure, do not match on raw volume.
Half the world's container traffic now flows through a short list of Asian hubs. Read the top of the table and you are reading the physical shape of global trade.
If you want to understand which vessels make these numbers, it helps to look at the ships themselves. The largest are documented in our companion piece on the biggest container ships — the 24,000-TEU class that only the busiest ports can handle.
A throughput figure is an annual abstraction. What is actually happening at a port is a constant churn of arrivals and departures — and that is where Marifest comes in. Every major port has a profile under /ports, and from there you can see which ships are at a port in the Marifest registry, with live arrivals drawn from AIS data on the live map.
Each call links straight to the vessel's file in the registry of 97,000+ ships: its specs, ownership chain, flag, and sanctions standing. So you can move from a top-three port, to the ships berthed there right now, to the company behind any one of them — all in a few clicks, and free to search.
How Marifest uses it
Marifest turns a port name into a living picture: who is alongside, who is inbound, and which company sits behind each hull. The open registry, the live map and the port profiles all line up on the same vessels.
Every major port has a page under /ports — location, role in the network, and the vessels currently associated with it, all from open data.
AIS positions on the live map show which ships are approaching or berthed in real time, so a port is never just a static figure.
Click any ship calling at a port and jump to its full record — specs, ownership, flag and sanctions standing — in the 97,000-ship registry.
Each vessel is tied to its operator and registered owner, so you can see which company is moving cargo through a given hub.
