Government Revises Windfall Tax on Fuel Exports

India has announced a fresh revision in export duties on key petroleum products as part of its ongoing policy of monitoring international energy markets and refining profitability.

The revised rates come into force from June 16, 2026, and apply specifically to diesel and aviation turbine fuel exports. The changes were notified through amendments to existing central excise notifications issued earlier this year.

The move reflects the government’s strategy of periodically adjusting export levies to align with developments in global crude oil markets and refining economics.

Diesel Export Duty Increased to ₹14 Per Litre

Under the revised structure, the special additional excise duty on diesel exports has been increased from ₹13.5 per litre to ₹14 per litre.

Diesel remains one of India’s most significant refined petroleum exports, and export duties are often adjusted to capture gains arising from favorable international refining margins.

The increase is expected to have implications for refiners involved in overseas diesel shipments, while remaining neutral for domestic consumers.

Aviation Turbine Fuel Levy Raised

The government has also increased the export duty on aviation turbine fuel.

The levy on ATF exports has been raised by ₹3 per litre, taking the total duty to ₹12.5 per litre. Aviation fuel has witnessed fluctuations in global demand and pricing, prompting periodic revisions in taxation structures linked to exports.

This adjustment aligns with the government’s practice of reviewing export duties in response to prevailing market conditions.

Petrol Export Duty Remains Unchanged

While diesel and ATF duties have been revised upward, the export duty on petrol remains unchanged at ₹1.5 per litre.

The decision suggests that current market conditions did not warrant any modification in petrol export taxation at this stage. Exporters of petrol will continue to operate under the existing duty framework.

No Impact on Domestic Fuel Prices

One of the key aspects of the latest announcement is that the revised levies apply exclusively to exports.

There will be no direct impact on:

• Retail petrol prices
• Retail diesel prices
• Domestic fuel taxation
• Fuel availability within India

The special additional excise duty is distinct from taxes imposed on domestic fuel sales, ensuring that local consumers remain unaffected by these export-oriented revisions.

Government Continues Dynamic Review Policy

India follows a structured review mechanism for export duties on petroleum products. The system enables policymakers to respond to changes in:

• International crude oil prices
• Refining margins
• Global fuel demand
• Energy market volatility

By recalibrating export duties periodically, the government seeks to balance industry profitability, revenue generation, and energy market stability.

This flexible approach allows India to adapt quickly to shifting global conditions while maintaining domestic price stability.

Significance for the Refining Sector

India is among the world’s largest refining hubs, exporting substantial quantities of refined petroleum products to international markets.

Changes in export duties can influence:

• Export profitability
• Refining margins
• Trade competitiveness
• Revenue generation

The latest increase in diesel and ATF export levies indicates the government’s continued focus on aligning taxation policies with prevailing market realities.

Conclusion

Effective June 16, 2026, India has increased export duties on diesel and aviation turbine fuel, raising the levy to ₹14 per litre and ₹12.5 per litre respectively. The duty on petrol exports remains unchanged at ₹1.5 per litre. While the revisions may impact exporters and refiners, domestic fuel consumers will experience no change in fuel prices, as the revised duties apply solely to exports and remain separate from local taxation structures.

Summary

The Government of India has increased the special additional excise duty on diesel and aviation turbine fuel (ATF) exports, effective June 16, 2026. The export duty on diesel has been raised to ₹14 per litre from ₹13.5 per litre, while the levy on ATF exports has increased to ₹12.5 per litre after a ₹3 hike. The export duty on petrol remains unchanged at ₹1.5 per litre. The revision is part of the government’s periodic review mechanism that adjusts export levies based on global crude oil prices and refining margins. Importantly, these changes apply only to exports and do not affect domestic fuel prices.
