New Delhi: The government has expanded excise‑duty exemptions to cover petrol blended with higher ethanol concentrations, enabling the introduction of fuel grades above the existing E20 standard.
In a notification released on Wednesday, the Ministry of Finance declared that petrol containing 22 per cent, 25 per cent, 27 per cent and 30 per cent ethanol will be exempt from central excise duty. The change applies to blends commonly labelled E22, E25, E27 and E30 and represents the first significant tax incentive for ethanol blends exceeding E20.
The decision is intended to bolster India’s ethanol blending programme, which aims to cut reliance on imported crude oil, reduce emissions and boost demand for domestically produced ethanol, as reported by Business Standard.
What’s new?
The government has added four new ethanol‑blended petrol categories to the central excise exemption list:
E22: 22 per cent ethanol and 78 per cent petrol
E25: 25 per cent ethanol and 75 per cent petrol
E27: 27 per cent ethanol and 73 per cent petrol
E30: 30 per cent ethanol and 70 per cent petrol
Each of these grades will be charged a nil rate of excise duty, provided they conform to Bureau of Indian Standards (BIS) specification IS 19850 and applicable taxes on both petrol and ethanol have been paid.
Bharati Balaji, deputy director general at the All India Distillers Association, said the move sends a strong demand‑side signal for the distilling sector and establishes a clear commercial route to utilise surplus ethanol production capacity that currently exceeds what the E20 programme requires.
Balaji added that the step will help reduce India’s crude‑oil import bill and strengthen energy security amid persistent volatility in global fuel markets. She urged state governments to harmonise their tax structures so the full benefit reaches both industry and consumers at the pump.
India’s Ethanol Production Capacity
India’s ethanol production capacity has expanded sharply in recent years, supported by government measures such as interest subsidies and higher blending targets.
As per information the government provided in the Rajya Sabha in October 2024, installed ethanol production capacity is around 20–21 billion litres per year. By comparison, ethanol demand for the current E20 blending programme is roughly 10–12 billion litres annually.
India’s ethanol‑blending drive has moved forward through several policy steps. In 2022 the government updated the National Policy on Biofuels, 2018, accelerating the target for 20 per cent ethanol blending in petrol from 2030 to the Ethanol Supply Year (ESY) 2025–26.
The programme has advanced faster than planned: state‑run oil marketing companies achieved 10 per cent blending in June 2022 — about five months earlier than the ESY 2021–22 target, according to data the petroleum ministry shared in Parliament in March 2025.
How will this affect consumers?
For most vehicle owners, immediate effects may be limited. Higher ethanol blends such as E22, E25, E27 and E30 are suitable only for vehicles specifically designed, tested and certified for more than 20 per cent ethanol.
Under Automotive Industry Standard (AIS) 171, approval covers passenger cars, three‑wheelers and some commercial vehicle segments. That means eligible passenger cars, utility vehicles, three‑wheelers and certain commercial vehicles can use higher blends, provided manufacturers have designed and certified them accordingly.
Most petrol vehicles on Indian roads today are engineered for blends up to E20. Running higher ethanol concentrations in vehicles not certified for them could impair engine performance, damage fuel‑system components and affect warranty coverage.
E85 launch begins next ethanol-blending phase
The excise exemption is timely, coming soon after the launch of E85, one of the highest ethanol‑blend fuels introduced in India.
Petroleum and Natural Gas Minister Hardeep Singh Puri unveiled E85 on World Environment Day in New Delhi. The fuel, which contains 85 per cent ethanol, is meant for flex‑fuel vehicles that can operate on high‑ethanol blends.
E85 is now available at 48 public-sector stations across India, priced below other ethanol blends. The rollout will expand fast: 50–100 stations within weeks, around 500 by end-2026, and 5,000 by end-2027.
Puri stated that E85 will be sold at roughly ₹20 per litre less than E20.
The E85 launch follows the arrival of India’s first mass‑market flex‑fuel passenger car, the Maruti Suzuki Wagon R Flex Fuel, which can run on ethanol‑petrol blends ranging from E20 to E85.
