Windfall tax reset: Petrol exports exempted, diesel and ATF duties hiked
Synopsis
India's windfall tax reset on 31 October removes petrol export duty entirely while hiking diesel and ATF levies — the latest in a series of fortnightly calibrations triggered by Middle East tensions and Strait of Hormuz disruptions since March 2026. The diverging treatment of petrol versus diesel and ATF signals that the government sees very different diversion risks across fuel categories right now.
Key Takeaways
The Centre withdrew the special additional excise duty on petrol exports on 31 October 2026 , bringing the levy to zero from ₹2.50 per litre .
Diesel export duty raised to ₹11.50 per litre from ₹8.50 per litre .
ATF export levy increased to ₹11 per litre from ₹10.50 per litre .
Fuel export duties were reintroduced in March 2026 after Middle East tensions and Strait of Hormuz disruptions pushed up global crude prices.
The Finance Ministry conducts fortnightly reviews of windfall tax rates to align duties with international price movements.
The Centre on Saturday, 31 October 2026 withdrew the special additional excise duty on petrol exports while simultaneously raising export levies on diesel and aviation turbine fuel (ATF), in the latest fortnightly revision of India's windfall tax framework on fuel. The move, notified by the Finance Ministry, takes effect immediately and marks a partial reversal of October's adjustments.
What the Revised Rates Mean
Petrol exports will now attract zero export duty, down from the earlier levy of ₹2.50 per litre. In contrast, the duty on diesel exports has been raised to ₹11.50 per litre from ₹8.50 per litre, while the ATF export levy has been increased to ₹11 per litre from ₹10.50 per litre.
Notably, the latest revision reverses part of an October adjustment in which the government had raised the petrol export levy to ₹2.50 per litre from ₹0.50 per litre, while simultaneously cutting the diesel duty to ₹8.50 per litre from ₹16 per litre. The see-saw pattern reflects how sensitively authorities are calibrating duties to real-time global price signals.
Why the Government Is Adjusting These Duties
India reintroduced fuel export levies in March 2026 after geopolitical tensions in the Middle East triggered a sharp rise in global crude prices and disrupted established energy supply routes. The stated rationale was to discourage domestic refiners from diverting refined product supplies to overseas markets when export margins turned more attractive than domestic sales, thereby safeguarding local fuel availability.
Energy security concerns deepened after disruptions to shipping through the Strait of Hormuz, a critical transit corridor for a significant share of India's crude oil imports. In response, refiners reportedly began diversifying their sourcing arrangements and monitoring export commitments more closely.
The Fortnightly Review Mechanism
The government conducts a fortnightly review of windfall tax rates, adjusting them in line with fluctuations in international crude oil and refined product prices. This mechanism was originally designed to prevent Indian refiners from earning outsized profits at the expense of domestic consumers during periods of elevated global energy prices.
Fuel export duties have undergone multiple revisions in recent months, according to Finance Ministry notifications, as authorities sought to balance domestic supply requirements against changing global market conditions. The recurrent adjustments underscore the volatility in global energy markets and India's ongoing effort to insulate its domestic fuel ecosystem from external shocks.
What to Watch Next
Analysts will be tracking whether the exemption on petrol exports signals a sustained easing — or a temporary relief driven by a softening in international petrol crack spreads. The diesel and ATF hikes suggest the government remains cautious about diversion risk in those categories. The next fortnightly review, due in mid-November, will indicate whether this reset holds or undergoes further calibration.
Point of View
Suggesting the government sees crack-spread pressure differently across fuel categories. What mainstream coverage tends to underplay is the structural vulnerability this fortnightly mechanism reveals — India's domestic fuel supply remains sufficiently exposed to export arbitrage that authorities feel compelled to adjust duties every two weeks. The reintroduction of these levies in March 2026 was framed as a temporary emergency measure; their continued presence and frequent recalibration suggest they have become a semi-permanent instrument of energy policy, with real implications for refinery planning and hedging strategies.

Frequently Asked Questions
What is the windfall tax on fuel exports in India?
India's windfall tax on fuel exports is a special additional excise duty levied on petrol, diesel, and ATF sold abroad by domestic refiners. It was reintroduced in March 2026 to prevent refiners from diverting supplies to overseas markets when global export margins exceeded domestic prices, thereby protecting local fuel availability.
Why has the government exempted petrol exports from duty now?
The government withdrew the petrol export duty on 31 October 2026 as part of its routine fortnightly review, which adjusts levies in response to international crude oil and refined product price movements. The exemption reverses an October hike that had set the petrol levy at ₹2.50 per litre.
By how much have diesel and ATF export duties been raised?
Diesel export duty has been raised to ₹11.50 per litre from ₹8.50 per litre, while ATF export levy has been increased to ₹11 per litre from ₹10.50 per litre, effective 31 October 2026.
What triggered the reintroduction of fuel export duties in 2026?
Fuel export levies were reintroduced in March 2026 following geopolitical tensions in the Middle East that caused a sharp rise in global crude prices and disrupted shipping through the Strait of Hormuz, a critical transit route for India's crude oil imports.
How often does India revise windfall tax rates on fuel?
The government conducts a fortnightly review of windfall tax rates, adjusting export duties on petrol, diesel, and ATF roughly every two weeks based on prevailing international crude oil and refined product prices.
