An entrepôt port is a port where goods are imported, stored, and then re-exported, often after processing, without being subject to import duties. It acts as a major transhipment and distribution centre for trade.
Singapore is a prime example of an entrepôt port due to its strategic location along major shipping routes and its large-scale transhipment activities, serving as a regional hub for trade.
Mumbai, Maracaibo, and San Francisco are major ports handling significant trade, but Singapore’s economy and port operations are fundamentally built around its role as an entrepôt, facilitating trade flow between different regions.
