The government issues notifications exempting higher grades of ethanol-blended petrol (EBP) from applicable central excise duties. The Central Board of Indirect Taxes and Customs (CBIC) notifies that fuel grades E22, E25, E27 and E30—covering petrol blended with ethanol at 22%, 25%, 27% and 30% by volume—are granted exemption from central excise duty. The exemption applies subject to conditions: excise duty should have already been paid on the base petrol used for blending, and GST should have been paid on the ethanol supplied for the blend. Separate reporting also notes that the Bureau of Indian Standards had previously set fuel quality norms in May for ethanol-containing fuels at these blend percentages, providing the technical basis for the graded products. One outlet also links the policy change to progress toward a stated ethanol blending target, noting that the 20% target is achieved as of December 2025. Overall, the notifications formalize nil central excise duty for these higher ethanol blend grades, while requiring payment of taxes on inputs as stipulated.
