Indian Industry Plus A Pratisrutiplus Suppliment
The combined Index of Eight Core Industries (ICI) in October 2025 has remained unchanged at 162.4 (provisional) as compared to the Index in October, 2024. The production of Fertilizer, Steel, Cement and Petroleum Refinery products recorded positive growth in October, 2025. The details of annual indices, monthly indices and growth rates are provided at Annex I and Annex II.
The ICI measures the combined and individual performance of production of eight core industries viz. Coal, Crude Oil, Natural Gas, Refinery Products, Fertilizers, Steel, Cement and Electricity. The Eight Core Industries comprise 40.27 percent of the weight of items included in the Index of Industrial Production (IIP).
The final growth rate of Index of Eight Core Industries for September 2025 was observed at 3.3 per cent. The cumulative growth rate of ICI during April to October, 2025-26 is 2.5 per cent (provisional) as compared to the corresponding period of last year.
The summary of the Index of Eight Core Industries is given below:
