Gail Mangalore Petrochemicals Limited (GMPL) is a wholly owned subsidiary of GAIL (India) Limited (GAIL), India’s leading gas major. It owns a Purified Terephthalic Acid (PTA) manufacturing plant in the Special Economic Zone of Mangalore. PTA is primarily used to produce polyester fibers and yarn. It is also used to manufacture plasticizers, liquid crystal polymers, and polybutylene terephthalate.

The company was earlier operating as JBF Petrochemicals Ltd (JBFPL). At inception, the 1.25 million tons per annum PTA Plant of JBFPL was one of the largest in India. During the final stages of construction, JBFPL defaulted on its borrowings leading to insolvency. GAIL emerged as the successful bidder during the insolvency resolution process and completed the acquisition in June 2023. Subsequently, GAIL has rechristened the company as GMPL. GMPL is now reviving the equipment and machinery and completing certain balance construction works.
