India's industrial output expanded 4.9 per cent in April under the revised series, following the government's latest update to the Index of Industrial Production (IIP) base year.
The revision, the tenth such exercise, broadens the index's scope by adding 120 new item groups and offers more detailed insights through separate indices for multiple sectors.
This is the first data released after the revision in base year to 2022-23. The factory output, measured in terms of the Index of Industrial Production (IIP), expanded by 5.7 per cent in April 2025, PTI reported.
The growth rates of the four sectors -- mining & quarrying, manufacturing, electricity & gas supply, water supply, sewerage & waste Management -- for April 2026 stood at (-) 5.1 per cent, 6.2 per cent, 4.9 per cent and 6.6 per cent, respectively, an official statement said.
The quick estimate of IIP stands at 118.9 against 113.1 in April 2025, it said.
The Ministry of Statistics & Programme Implementation (MoSPI) has revised the base year of the Index of Industrial Production (IIP) from 2011-12 to 2022-23. The revised basket consists of 1,042 products mapped to 463 item groups, including 120 new item groups, according to PTI. .
The base year revision exercise was undertaken under the aegis of the Technical Advisory Committee for Base Year Revision of the All India Index of Industrial Production (TAC-IIP).
The committee's report was released on May 25, 2026, laying the foundation for a more robust, relevant, and comprehensive measure of industrial production in India. This is the 10th revision of the base year for IIP. The first IIP was prepared with a base year 1937.
According to the MoSPI, the new IIP series provides greater granularity with separate indices for the generation of electricity through renewable and non-renewable, gas supply, fuel minerals, metallic minerals and non-metallic minerals, water supply, sewerage and waste management, as per PTI.
In the new IIP series, a total of 120 new item groups have been added, including cards with a magnetic stripe (debit card, credit card), CCTV camera, articles of non-woven textiles, parts of aircraft and spacecraft, stents, and vaccine.
Also, 64 item groups, including kerosene, fluorescent tubes and CFLs, tubes for bicycle/ tricycle/ rickshaw/LMV tyres, printing machinery, and sewing machines, have been dropped, PTI report stated.
An expanded item basket improves representativeness, captures diversification in industrial production, and reflects emerging industrial products and technologies, MoSPI said, adding that the IIP will be released every month with a time lag of 28 days from the reference month. (With Agency Inputs)
