New Delhi: In a significant step towards strengthening energy security and accelerating the country’s biofuel transition, the central government has exempted higher ethanol-blended petrol variants from excise duty, paving the way for wider adoption of fuel blends beyond the existing E20 standard.
The government has issued notifications granting a nil central excise duty rate for ethanol-petrol blends including E22, E25, E27 and E30, provided they conform to the standards prescribed by the Bureau of Indian Standards (BIS). The move comes at a time when India has already achieved its target of 20% ethanol blending in petrol ahead of schedule, marking a major milestone in its efforts to reduce dependence on imported crude oil and promote cleaner fuels.
Under the new framework, E22 fuel will consist of 78% petrol and 22% ethanol, while E25, E27 and E30 will contain 25%, 27% and 30% ethanol respectively. The tax exemptions apply in cases where the applicable duties have been paid on motor spirit and Goods and Services Tax (GST) has been paid on the ethanol component used in the blends.
The changes have been introduced through amendments to Notification No. 11/2017-Central Excise and Notification No. 28/2002-Central Excise. Separate notifications have also exempted these higher ethanol blends from additional excise duties as well as road and infrastructure cess, further improving their economic viability.
The decision follows recent efforts by the BIS to establish technical standards for fuel blends containing up to 30% ethanol. In May, the standards body notified specifications for E22, E25, E27 and E30 fuels, laying the groundwork for future adoption of higher blending ratios across the country.
India’s ethanol blending programme has expanded rapidly in recent years, supported by increased production from both sugarcane-based and grain-based distilleries. Despite the success of the E20 rollout, industry stakeholders have been advocating for higher blending levels, citing surplus ethanol availability and the potential to reduce oil import dependence.
The push for greater ethanol usage has gained urgency amid global energy market uncertainties. Rising geopolitical tensions in West Asia and concerns over disruptions in the Strait of Hormuz, a critical route through which nearly one-fifth of global oil supplies pass, have highlighted the importance of diversifying energy sources and improving domestic fuel security.
Experts believe that a transition to higher ethanol blends could also significantly improve ethanol production capacity utilization, which currently stands at around 50%, while contributing to lower carbon emissions and supporting India’s long-term sustainability goals. Although the government has not yet announced a formal roadmap for nationwide E25 or E30 adoption, the latest tax incentives signal a clear policy direction toward deeper integration of biofuels into the country’s transport fuel mix.
