The Kolkata port serves the large and rich hinterland of the Ganga-Brahmaputra basin covering the states of West Bengal, Assam, Bihar and eastern Uttar Pradesh. Tea, jute and cotton textiles, coal, lac, hides, engineering goods are some items of export from this region via Kolkata port. The Kolkata port is an inland riverine port situated on the left bank of the River Hooghly in West Bengal. It is located inland at a distance of 128 km from the Bay of Bengal. It is a tidal port. As a result, the port faces the problem of siltation and requires constant dredging. It is the most important port in the eastern region. Ports hold a special position in India’s international trade. India’s trade with foreign countries is carried on mainly through the ocean routes from the ports located along the coast. 95 percent of the country’s trade volume (68 percent in terms of value) is moved by the sea via the ports. Hence, ports have great significance in the economy of India.
