The Travancore Cochin Chemical Ltd known locally as TCC is a limited liability company where the majority of the shares of the company is held by the state government. This company was started as a partnership concern in the name “Travancore Mettur Chemicals” with FACT and MCIC (Mettur Chemicals and Industrial Corporation) as partners. In 1951 the company was registered as a public limited company with the major share held by the Kerala State and the company was renamed at “Travancore Cochin Chemicals Ltd”.
