India Hikes Export Windfall Tax on Diesel, Petrol, and Jet Fuel

NEW DELHI, India — The Indian government has increased Special Additional Excise Duty (SAED) rates on exports of diesel, petrol, and aviation turbine fuel (ATF), according to an official gazette notification released by the Ministry of Finance. Effective August 3, 2026, the export duty on diesel rises to ₹24 per litre (up from ₹15.5 per litre), petrol export duty increases to ₹3.5 per litre (up from ₹2.5 per litre), and ATF export levy moves to ₹22 per litre (up from ₹14.5 per litre). The recalibration comes during the central government's fortnightly review as international refining margins widen, prompting authorities to prioritize domestic fuel security and curb excessive overseas shipments.

Breakdown of Revised Fuel Export Duties Effective August 3

Under the administrative order issued by the Department of Revenue under the Ministry of Finance, the revised duties apply directly to outgoing international shipments of refined petroleum products.

The rate adjustment raises export levies across all three major refined fuel categories:

• Diesel Exports: Increased by ₹8.5 per litre, raising the total export levy from ₹15.5 to ₹24 per litre.

• Aviation Turbine Fuel (ATF) Exports: Raised by ₹7.5 per litre, bringing the duty from ₹14.5 to ₹22 per litre.

• Petrol Exports: Upwardly adjusted by ₹1 per litre, moving from ₹2.5 to ₹3.5 per litre.

Market Drivers Behind Fortnightly Tax Adjustments

The government calculates windfall tax levies every two weeks using international benchmark crude oil prices and global refinery crack spreads—the commercial margin between unrefined crude input costs and processed fuel sale prices.

When international refining margins expand significantly due to global supply disruptions or regional demand spikes, Indian refiners experience increased commercial incentives to ship diesel, jet fuel, and petrol abroad. By increasing Special Additional Excise Duties, the government disincentivizes unconstrained fuel exports, ensuring state-run and private oil marketing companies maintain adequate reserves for domestic retail networks, agricultural machinery, and civil aviation fleets.

Importantly, the Finance Ministry confirmed that excise duty structures on petrol, diesel, and jet fuel cleared for domestic consumption remain completely unchanged.

Impact on Domestic Energy Companies and Markets

The upward revision in export taxes directly affects major domestic refining companies, including private exporters such as Reliance Industries Limited and Nayara Energy, along with public sector units like Indian Oil Corporation Limited (IOCL), Bharat Petroleum Corporation Limited (BPCL), and Hindustan Petroleum Corporation Limited (HPCL).

While higher export levies temporarily moderate gross refining margins (GRMs) realized on international cargoes, energy analysts note that refiners continue to benefit from robust domestic consumption growth. Market participants on equity exchanges track these fortnightly rate adjustments closely to model operating earnings and capital allocation across the energy sector.

Statement from Government Officials

According to officials familiar with central tax administration, fortnightly duty revisions remain calibrated to global oil market conditions.

"According to officials, the recalibration of Special Additional Excise Duty on exported fuels ensures that domestic energy supply remains secure while absorbing windfall profits generated by fluctuating international refining margins."

Why It Matters

The export duty increase carries key practical implications across multiple economic sectors:

• For Capital Markets: Directly influences gross refining margins and export revenue realizations for domestic oil refiners.

• For Aviation & Transport: Prioritizes jet fuel and diesel availability for domestic airlines, transport operators, and agricultural supply chains.

• For Domestic Retail Consumers: Ensures retail fuel stations remain fully stocked without impacting retail pump prices.

Key Facts at a Glance

• Diesel Export Levy: Raised to ₹24 per litre from ₹15.5 per litre starting August 3.

• ATF Export Levy: Increased to ₹22 per litre from ₹14.5 per litre.

• Petrol Export Levy: Adjusted upward to ₹3.5 per litre from ₹2.5 per litre.

• Domestic Fuel Impact: Retail prices for petrol, diesel, and jet fuel within India remain unaffected.
