• Cotton Corporation of India (CCI) was established in 1970 under the administrative control of the Ministry of Textiles as a Public Sector Undertaking under the Companies Act 1956.
• In the initial period of setting up, as the only public sector undertaking in the field of marketing of cotton, CCI played a role of a canalizing agency for imports of cotton and purchase of raw cotton for giving necessary price support to enterprising cultivators and also for procuring raw cotton for textile mills.
• The role and function of CCI continued to enlarge with the changing cotton scenario in the country. 
• Now, the major role of the CCI is to undertake price support operations, whenever the market prices of kapas fall below the minimum support prices (MSP) announced by Govt. of India, without any quantitative limit. 
• Besides MSP operations, to fulfil the raw material requirement of the domestic textile industry particularly for lean season, CCI undertakes commercial purchase operations.
