Core Industries of India

The core industries of India are eight essential sectors that significantly influence the country’s economic activity. These industries collectively account for 40.27% of the total weight of the Index of Industrial Production (IIP), which measures overall industrial growth.

The eight core industries are:
  • Petroleum Refinery Products: This sector has the highest weightage and includes products like petrol, diesel, and aviation fuel.
  • Electricity: The generation, transmission, and distribution of electricity is vital for various sectors of the economy.
  • Steel: A key raw material used in construction, infrastructure, and manufacturing.
  • Coal: This industry focuses on the mining and production of coal, a primary source of energy.
  • Crude Oil: This includes the exploration, extraction, and refining of crude oil.
  • Natural Gas: The extraction, processing, and distribution of natural gas for energy and industrial use.
  • Cement: A key ingredient for infrastructure and construction projects.
  • Fertilizers: This sector produces fertilizers essential for agricultural output.

 

The performance of the core industries is tracked monthly by the Office of the Economic Adviser, part of the Ministry of Commerce and Industry. The Index of Eight Core Industries (ICI) serves as an important indicator for the health of India’s overall economy.
