INDEX OF EIGHT CORE INDUSTRIES (BASE
YEAR: 2011-12=100) FOR SEPTEMBER, 2025
Posted On: 21 OCT 2025 5:00PM by PIB Delhi
The combined Index of Eight Core Industries (ICI) increased by 3.0 per cent (provisional) in September,
2025 as compared to the Index in September, 2024. The production of Steel, Cement, Electricity and
Fertilizer recorded positive growth in September, 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 August 2025 was observed at 6.5 per cent.
The cumulative growth rate of ICI during April to September, 2025-26 is 2.9 per cent (provisional) as
compared to the corresponding period of last year.
