The government notifies that petrol blended with ethanol at higher concentrations—specifically 22%, 25%, 27% and 30% by volume—will be exempt from central excise duty. The move is linked to the achievement of the ethanol blending target, which is reported as being met by December 2025, when the 20% goal is said to have been reached. Earlier, fuel standards were put in place by the Bureau of Indian Standards (BIS). In May, BIS notified specifications for fuels containing ethanol blends in the same 22% to 30% range, enabling the regulatory framework for such higher blends. With these standards in place, the excise exemption applies to petrol produced with these higher ethanol percentages rather than lower blends. Multiple sources describe the policy as a nil duty measure for eligible higher ethanol blends, while referencing the background of BIS norms and the government’s blending target status. The announcement therefore combines product standards (BIS specifications) with a fiscal incentive (central excise exemption) for ethanol-containing petrol within the specified blend range.
