KESAR Petro Products is an Indian manufacturer of Bisphenol-A, a life-saving drug intermediary. In 1994, it petitioned the government against dumping of Bisphenol-A by Japans Mitsui & Co. On investigation, the government felt Mitsui was indeed dumping the chemical, that is, selling it at lower than its production cost. On March 13, 1994, the government slapped a duty of Rs 7,477 per tonne against Mitsui. This was the second anti-dumping investigation in India.
