The short answer

  • The waiver covers E22, E25, E27 and E30 blends that meet BIS specification IS 19850.
  • Its purpose is to stop excise duty being charged again after already-taxed petrol and GST-paid ethanol are blended.
  • The government says this does not announce an immediate rollout of higher blends.
  • Drivers should not expect an instant reduction in today's regular petrol price.

PurposeAvoid double tax
Retail rolloutNot announced

What the notification does

Ethanol blending can be treated as a manufacturing activity. Petrol already bears excise duty and ethanol bears GST. Without an exemption, the final blended product could attract excise duty again. The June 10 notification extends the same protection already available to blends up to E20 to E22, E25, E27 and E30.

Excise duty on normal petrol endedThe exemption concerns the blended product and possible double levy.

Hindi video context

The video raised the right question: which petrol became cheaper? The official clarification shows that this is a tax-structure change, not an immediate price cut.
