Caitlyn India (CIPL) will invest Rs 4 billion to set up a 50,000 TPA integrated phosphoric acid plant in southern India. The company is scouting port-accessible sites and plans to commission the facility by FY 2027. The project will span 30–50 acre and aims to reduce India's dependency on imported phosphoric acid. 

The plant will adopt hemihydrate–dihydrate (HH-DH) technology, enabling high-purity phosphoric acid production with cleaner gypsum by-products. A captive sulphuric acid unit will be included for operational efficiency. Initially, output will be supplied to domestic fertiliser manufacturers, with future captive use once CIPL sets up its own NPK fertiliser facility. 

India's phosphoric acid demand is projected to rise from 4,948 KTPA in 2018 to 8,773 KTPA by 2030, while the market size is expected to nearly double by 2033. Despite this growth, imports dominate supply. 

CIPL plans to source rock phosphate from Morocco, Jordan, and Egypt through long-term contracts. The investment aligns with national fertiliser self-sufficiency targets and is expected to generate employment and boost the agri-input ecosystem.
