Overview
- The finance ministry issued a notification on June 10 exempting central excise duty on petrol blended with 22%, 25%, 27% and 30% ethanol subject to conformity with BIS rules.
- The Bureau of Indian Standards issued fuel-quality specifications for E22–E30 in May 2026, creating the technical framework needed before any retail rollout.
- Union ministers have publicly advanced the agenda for higher blends and Nitin Gadkari said he signed rules to legally authorise 100% ethanol and flagged pilots and planned flex‑fuel vehicle launches.
- E22–E30 are not yet sold at pumps and most vehicles are certified only up to E20, so manufacturers and fuel retailers must complete testing, material validation and infrastructure changes over coming months.
- Analysts say the excise relief will first boost ethanol producers and fuel suppliers and could lower oil imports over time, but motorists may face modest mileage loss and may not see immediate price cuts at the pump.
