India’s IIP growth rate with revised base year stands at 4.9% in April
Jun-01-2026

The Ministry of Statistics and Programme Implementation (MoSPI) has revised the base year of the All India Index of Industrial Production (IIP) from 2011-12 to 2022-23 with the objective of making the index more representative of the current structure and dynamics of the industrial sector. The revised series incorporates an updated item basket, a revised weighting structure, and enhanced sectoral coverage to better capture recent developments in industrial activity across the economy. The IIP growth rate for the month of April 2026 (Base 2022-23=100) is 4.9% as compared to April 2025. Within the index, manufacturing showed robust performance, while mining sector contracted during the month. The Quick Estimate of IIP stood at 118.9 against 113.4 in April 2025. The growth in April 2025 was 5.7%. 

The growth rates of the Four sectors, growth rate for mining & quarrying (having 11.053% weight in total index) stood at (-)5.1% in April 2026 over 0.6% April 2025. Growth rate for manufacturing (having 76.062% weight in total index) stood at 6.2% in April 2026 over 6.4% in April 2025. Growth rate for electricity & gas supply (having 10.865% weights in total index) stood at 4.9% in April 2026 over 6.1% in April 2025. Growth rate for water supply, sewerage & waste management (having 2.020% weight in total index) stood at 6.6% in April 2026 over 8.2% in April 2025. The indices of Industrial Production for Mining & Quarrying, Manufacturing, Electricity & Gas Supply and Water Supply, Sewerage & Waste Management for the month of April 2026 stood at 104.6, 119.3, 125.5 and 146.1, respectively.

Within the Manufacturing sector, 17 out of 23 industry groups at NIC 2 digit-level have recorded a positive growth in April 2026 over April 2025. The top three positive contributors for the month of April 2026 are – “Manufacture of motor vehicles, trailers and semi-trailers” (12.7%), “Manufacture of electrical equipment” (19.2%) and “Manufacture of machinery and equipment n.e.c.” (12.9%).

As per the Use-Based Classification, the indices stood at 112.2 for Primary Goods, 132.1 for Capital Goods, 119.7 for Intermediate Goods and 129.7 for Infrastructure/ Construction Goods for the month of April 2026. Further, the indices for Consumer durables and Consumer non-durables stood at 119.1 and 112.4 respectively. The corresponding growth rates of IIP as per Use-Based Classification in April 2026 over April 2025 are 0.8% in Primary Goods, 16.0% in Capital Goods, 7.7% in Intermediate Goods, 7.1% in Infrastructure/ Construction Goods, 4.3% in Consumer durables and 2.8% in Consumer non-durables.  Based on Use-Based Classification, top three positive contributors to the growth of IIP for the month of April 2026 are Intermediate Goods, Capital Goods and Infrastructure/ Construction Goods.

In the new IIP series (2022–23), the coverage has been broadened by incorporating Gas Supply and Water Supply, Sewerage & Waste Management activities, while retaining the existing three core sectors—Mining, Manufacturing, and Electricity. In the Mining sector, the new series includes minor minerals and rare earth minerals in addition to major minerals, making the index more inclusive and representative of the sector. This expansion ensures that the IIP captures more comprehensive and accurate reflection of industrial production in the economy and aligns it better with global standards.

The new IIP series provides a more detailed disaggregation of industrial activities, enabling better analysis of sectoral performance. In the Mining & Quarrying sector, the index is now available at a more granular level, covering: (i) Fuel Minerals, (ii) Metallic Minerals, including Rare Earth Minerals, and (iii) Non-Metallic Minerals, including Minor Minerals. This enhanced classification offers deeper insights into the contribution and performance of different mineral categories.

Similarly, the Electricity Index is now compiled at a more disaggregated level based on the source of electricity generation: (i) Non-Renewable Sources and (ii) Renewable Sources. This improvement allows the index to better capture the ongoing transition towards cleaner and more sustainable energy sources, while providing a clearer picture of changes in the energy mix over time.

The item basket and weights have been revised to add relevant commodities and remove outdated ones, ensuring that each item or sector is assigned appropriate significance. The revised basket consists of 1,042 products mapped to 463 item groups as compare to 839 items mapped to 407 item groups in 2011-12 series. This revision better captures changes in the industrial landscape, including the emergence of new products and shifts in production patterns over time.
