The Chennai based Tanfac Industries Ltd, is a company jointly promoted by Aditya Birla Group and TIDCO. Production commenced in Mar.'85 and soon achieved 100% capacity utilisation.

The company manufactures aluminium fluoride (inst. cap. : 9000 tpa) from its's plant at Cuddalore, Tamil Nadu. It also manufactures sulphuric acid, oleum, anhydrous hydrofluoric acid, cryolite and other fluorides. The company gets technical support from M/s Kvaemer Buss, Switzerland, M/s. CHENCO. Germany.

The company's diversification scheme for the manufacture of Organo Fluorine Chemicals was completed in 1998-99. The Organo Fluorine Chemicals viz. 2,4, Dichloro fluorobenzene, Acetophenone etc., used as intermediate chemicals in the manufacture of new generation antibiotics (bulk drugs) called Ciprofloxacin, Enrofloxacin etc. The technology was sourced from Dalian F Chem, China.

In 2000-01 the operations of the Company's new project for manufacture of DFCA remained suspended as it is uneconomical to operate the plant at the current depressed market price. The Company's R&D team has successfully engineered a new process for manufacturing Inorganic Fluorine chemicals in the existing plant, with a minimum addition to the equipment.
