The new IIP series (base 2022-23): what happened?
The IIP tracks how much factories, mines and power plants produce each month. An old base year means old products and old weights. The new 2022-23 base updates the basket of items, the weights and the coverage, guided by a technical committee (TAC-IIP) whose report came out on 25 May 2026.
- 17 of 23 manufacturing groups grew in April 2026.
- Top contributors: motor vehicles and trailers (12.7%), electrical equipment (19.2%) and machinery (12.9%).
- Use-based: capital goods grew 16.0%, intermediate goods 7.7%, infrastructure and construction goods 7.1%, primary goods 0.4%.
- Consumer durables grew 4.3% and non-durables 2.8%.
How is IIP classified?
- By sector: mining and quarrying, manufacturing, electricity and gas supply, and now water supply, sewerage and waste management.
- By use: primary goods, capital goods, intermediate goods, infrastructure/construction goods, consumer durables and consumer non-durables.
- Manufacturing groups follow the National Industrial Classification (NIC 2025) at 2-digit level.
