India Raises Windfall Tax: Diesel Climbs to ₹55.5/L, ATF to ₹42/L

The Central Government has raised export duty on aviation turbine fuel (ATF) in a fresh move aimed at preserving domestic fuel availability amid mounting pressure in global oil markets.
The decision comes as crude oil prices continue to rise sharply following escalating geopolitical tensions in West Asia.
Export Duty On Diesel and ATF Increased
As per the latest notification issued by the Ministry of Finance, export duty on diesel has been increased sharply from ₹21.5 per litre to ₹55.5 per litre.
Export duty on aviation turbine fuel has also been raised from ₹29.5 per litre to ₹42 per litre.
However, export duty on petrol has been left unchanged at nil. The revised rates came into force immediately following the notification issued on April 11.
Move Aimed at Protecting Domestic Supply
The duty hike reflects the government’s efforts to ensure adequate domestic availability of petroleum products at a time when elevated international prices could incentivise refiners to increase exports.
Export duties on petroleum products, commonly referred to as windfall taxes are used as a policy tool to moderate outbound shipments and preserve local supply when global refining margins rise significantly
Global Oil Rally Driving Policy Tightening
The latest revision comes amid significant disruption in global oil markets triggered by tensions involving the US, Israel, and Iran.
Supply concerns surrounding the Strait of Hormuz, one of the world’s most critical oil transit routes have intensified fears of prolonged disruption, pushing Brent crude prices above $100 per barrel.
The resulting rise in petroleum product prices has increased pressure on governments globally to safeguard domestic energy availability.
Potential Impact on Refiners and Aviation Supply Chain
Higher export duty on ATF may impact export margins for refiners while potentially supporting greater domestic supply availability for aviation fuel distributors and domestic carriers.
The measure may also reduce volatility in local ATF pricing if international prices remain elevated over the near term.
The move reflects the government’s balancing act between enabling refiners to benefit from strong global markets and ensuring local sectors are protected from supply disruptions.
