The Centre has expanded excise duty exemptions to petrol blended with higher levels of ethanol, clearing the way for the introduction of fuel grades above the current E20 standard.
In a notification issued on Wednesday, the Ministry of Finance exempted petrol containing 22%, 25%, 27% and 30% ethanol from central excise duty. The move marks the first major tax incentive for ethanol blends above E20.
The decision is part of India’s ethanol blending programme, which seeks to cut dependence on imported crude oil, reduce emissions and create additional demand for domestically produced ethanol.
New fuel grades brought under tax exemption
Four new categories have been added to the excise exemption framework:
- E22: 22% ethanol and 78% petrol
- E25: 25% ethanol and 75% petrol
- E27: 27% ethanol and 73% petrol
- E30: 30% ethanol and 70% petrol
All four grades will attract a nil rate of excise duty, subject to two conditions:
- The fuel must comply with Bureau of Indian Standards (BIS) specification IS 19850.
- Applicable duties and taxes on both petrol and ethanol should already have been paid.
Industry sees demand boost
Bharati Balaji, Deputy Director General of the All India Distillers Association, said the move provides a strong demand signal for the ethanol industry.
“For the distilling industry, this is a powerful demand-side signal. It creates a clear commercial pathway to deploy our surplus ethanol production capacity, which currently stands well above E20 programme requirements,” Balaji said.
She added that higher ethanol usage could help lower India’s crude oil import bill and strengthen energy security amid volatile global fuel markets.
Balaji also urged state governments to align their tax structures so that the benefits reach consumers and the industry.
India has surplus ethanol capacity
India’s ethanol production capacity has expanded rapidly in recent years.
According to information shared in the Rajya Sabha in October 2024:
- Installed ethanol production capacity stands at 20-21 billion litres annually.
- Demand under the current E20 programme is estimated at 10-12 billion litres per year.
India revised the National Policy on Biofuels, 2018, in 2022 and advanced the target for achieving 20% ethanol blending to Ethanol Supply Year (ESY) 2025-26, from the earlier goal of 2030.
State-run oil marketing companies reached 10% blending in June 2022, about five months ahead of schedule, according to information shared by the petroleum ministry in Parliament in March 2025.
What it means for consumers
The immediate impact on most motorists is expected to be limited.
Higher ethanol blends can only be used in vehicles that are specifically designed and certified for fuels containing more than 20% ethanol.
Under Automotive Industry Standard (AIS) 171, the framework covers:
- Passenger vehicles
- Utility vehicles
- Three-wheelers
- Certain categories of commercial vehicles
Most petrol vehicles currently on Indian roads are compatible only with E20 fuel.
Using higher ethanol blends in vehicles that are not certified for them could:
- Affect engine performance
- Damage fuel-system components
- Impact warranty coverage
E85 rollout marks next phase
The excise-duty relief comes days after the launch of E85 fuel, which contains 85% ethanol.
Petroleum and Natural Gas Minister Hardeep Singh Puri launched E85 on World Environment Day (June 5) in New Delhi.
The fuel is meant for flex-fuel vehicles capable of operating on high ethanol blends.
Initial rollout details:
- Available at 48 fuel stations operated by public-sector oil marketing companies.
- Expected to expand to 50-100 outlets within weeks.
- Target of 500 stations by end-2026.
- Target of 5,000 stations by end-2027.
According to the minister, E85 will cost around ₹20 per litre less than E20 fuel.
The launch follows the introduction of the Maruti Suzuki Wagon R Flex Fuel, India’s first mass-market flex-fuel passenger vehicle capable of running on blends ranging from E20 to E85.
TL;DR
The government has exempted E22, E25, E27 and E30 petrol blends from excise duty, extending tax support beyond E20. The move is aimed at boosting ethanol consumption, reducing crude imports and supporting India’s clean fuel programme, though most existing vehicles remain compatible only with E20.
AI Summary
- The Centre has waived excise duty on E22, E25, E27 and E30 petrol blends.
- The exemption applies to fuels meeting BIS standards.
- India has ethanol production capacity of 20-21 billion litres annually.
- Most existing petrol vehicles are compatible only with E20.
- E85 fuel has been launched and will be available at more outlets over the next two years.
