New Index of Core Industries series with base year 2022-23 adds iron ore
DPIIT's Office of Economic Adviser released the first Index of Core Industries (ICI) with base year 2022-23 on 20 July 2026, replacing the 2011-12 series and raising the number of core industries from eight to nine with iron ore.
Summary
The Index of Core Industries (ICI) moved to a new base year of 2022-23 on 20 July 2026, when the Office of Economic Adviser, DPIIT, released the June 2026 provisional index in the revised series, replacing the 2011-12 series. The new Index of Core Industries adds iron ore as a new item, so the number of core industries rises from eight to nine. The new Index of Core Industries uses gross production for steel instead of net production, to be consistent with the Index of Industrial Production (IIP), and retains only raw coal, excluding coal middling and washed coal to avoid double counting. Weights for the new series are derived from the IIP (2022-23) series and pro-rated to 100.
