The industrial city has several major factories, including South Asian Petrochemicals Ltd, Indian Oil Corporation Limited (IOCL), Exide, Shaw Wallace, Tata Chemicals, Petrochemicals and Hindustan Lever, in addition to various light industries. The port has attracted Major International Petrochemicals Companies, like Mitsubishi Chemical Corporation (MCC). Mitsubishi Chemicals has the Second Largest Terephthalic Acid Producing Plant in Haldia. A large number of companies are also being set up now, Dredging Corporation of India Limited (DCI), primarily being ancillary industries to the Petrochemicals.
The Petrochemicals is the second largest project of such kind in India.
The Haldia Township is bordered by the Haldi River an offshoot of the Ganges River.
The riverside in Haldia is a favorite destination for residents and one can see people strolling down the riverside during the evenings. A catamaran service direct from Kolkata to Haldia was in service. It was later withdrawn due to its high price and decreasing number of passengers.
Haldia is also a base of Indian Coast Guard. There is a hoverport to house two of the six hovercrafts belonging to the Indian Coast Guard.
