About this page
The section, division, group, class and sub-class on this page are taken word for word from the official document “National Industrial Classification (All Economic Activities) 2008”, Central Statistical Organisation, Ministry of Statistics and Programme Implementation, Government of India.
This is reference information on the classification of a business activity. It is not advice on which code your own business should declare, and the official NIC document prevails if the two ever differ. A change in the classification, including the MoSPI concordance to NIC 2025, re-opens this page for checking.
