The Department for Promotion of Industry and Internal Trade (DPIIT) is set to unveil the updated Index of Core Industries (ICI) on July 20, 2026, with a new base year of 2022–23, replacing the current series based on 2011–12, as per an official statement. The monthly compiled ICI will include the June 2026 provisional data and a back series spanning from April 2023 to May 2026, covering 38 months.
The weights for the new ICI series have been determined based on the Index of Industrial Production (IIP) 2022–23 series released by the Ministry of Statistics and Programme Implementation (MoSPI), following the established methodology. The weights of the ICI basket items have been redistributed from the IIP to finalize the weights of the ICI item basket, totaling 100.
Iron Ore has been added as a core industry in the revised ICI series due to its extensive use in industrial production and significant contribution to industrial development, increasing the core industries from eight to nine. The Steel Index in the revised series now uses gross production data instead of net production data for consistency with the IIP.
In the Coal sector, the revised ICI series retains only Raw Coal, excluding Coal Middlings and Washed Coal to avoid double counting, as both are derived from Raw Coal. The current Index of Eight Core Industries measures the production performance of Coal, Crude Oil, Natural Gas, Refinery Products, Fertilizers, Steel, Cement, and Electricity, accounting for 40.27% of the items in the Index of Industrial Production.
