Hindustan Organic Chemicals Limited (HOC) was set up by the Government of India in 1960 with the objective of attaining self-reliance in basic organic chemical’s needs. In fact this was the first endeavor to indigenize manufacture of basic chemicals and to reduce country’s dependence on import of vital organic chemicals. HOC, started as small chemical unit, and expanded to a multiunit company with two units at Rasayani and Kochi and one subsidiary unit. The Rasayani unit was closed in the year 2018 due to nonviability of its old plants.

It was expected that indigenous manufacture of these chemical intermediates will give impetus to downstream industries resulting in setting up of chemical units and achieving self-sufficiency for the country in this area. This objective of setting up HOC has been achieved and at present more than 500 units based on HOC’s products have been set up all over the country which have not only succeeded in meeting the goal of self-sufficiency but also entered the international markets earning precious foreign exchange by exporting chemicals, dyes and drugs.
