It can be divided into super-sized ports (annual throughput > 30 million tons), large ports (annual throughput between 10 to 30 million tons), medium ports (annual throughput between 1 to 10 million tons), and small ports (annual throughput < 1 million tons).
Classificationaccording to the usage
Ports can be classified according to their usage into commercial ports, military ports, fishing ports, and industrial ports.
Commercial ports
Commercial ports are ports where merchant ships stop and handle passenger and cargo transportation business. They provide various facilities and conditions for berthing ships, loading and unloading passengers and cargo, supplying fuel and other provisions, as well as repairing ships. They serve as hubs for water and land transportation and as distribution centers for goods, with their size typically indicated by their throughput. Based on their functional structure, commercial ports can be further classified into comprehensive ports and specialized ports (such as oil ports).
