Government raises export duty on diesel and aviation fuel while reducing tax on petrol exports; retail fuel prices remain unchanged

The Central Government has revised the windfall tax structure on petroleum products as part of its scheduled fortnightly review, introducing higher export duties on diesel and aviation turbine fuel (ATF) while reducing the levy on petrol exports. The revised rates came into effect on July 16, 2026, and are aimed at responding to recent developments in global crude oil markets and changing refining margins.

The latest decision comes as international crude oil prices continue to remain volatile amid geopolitical tensions in West Asia and concerns over global energy supplies. Despite the tax revision, there is no immediate change in the retail prices of petrol and diesel sold at fuel stations across India, as these taxes apply only to exports.

Revised Windfall Tax Rates Effective July 16

Under the latest notification, the government has made the following changes to export duties on petroleum products:

• Petrol export duty has been reduced from ₹4 per litre to ₹2.50 per litre.
• Diesel export duty has been increased from ₹8.50 per litre to ₹15.50 per litre.
• Aviation Turbine Fuel (ATF) export duty has been raised from ₹7.50 per litre to ₹14.50 per litre.

These revised rates are now applicable from July 16, 2026, following the government's routine review of windfall taxes, which is generally conducted every two weeks based on market conditions.

Why Has the Government Changed the Tax Structure?

The decision comes against the backdrop of rising international crude oil prices and renewed uncertainty in global energy markets.

In recent trading sessions, Brent crude oil prices climbed by nearly 2%, crossing the $84-per-barrel mark, reaching their highest level in about a month. Analysts attribute the increase to escalating geopolitical tensions in West Asia, which have intensified concerns over the stability of global oil supplies.

One of the major factors influencing crude prices is the growing security risk around the Strait of Hormuz, a strategically important shipping route through which nearly 20% of the world's crude oil supply passes. Any disruption in this region has the potential to significantly impact international oil markets.

In addition, reports of attacks on oil tankers and reduced exports from several major producing countries have tightened global fuel supplies. At the same time, improved profitability in diesel refining has prompted the government to revise export duties to better align with prevailing market conditions.

Will Petrol and Diesel Become More Expensive?

For consumers, the immediate answer is no.

The revised windfall tax applies only to exports of petroleum products and does not directly affect the retail prices of petrol or diesel sold at fuel stations across the country.

Retail fuel prices in India are determined separately by oil marketing companies based on multiple factors, including international crude prices, exchange rates, transportation costs, taxes, and marketing margins. Therefore, the latest export duty revision is not expected to result in an immediate increase in pump prices for consumers.

Background: Temporary Restrictions on Bulk Fuel Purchases

The latest tax revision follows measures introduced by the government in June 2026, when temporary restrictions were imposed on bulk purchases of petrol and diesel from retail fuel outlets.

The move was intended to:

• Prevent hoarding and misuse of fuel.
• Ensure uninterrupted fuel availability for individual consumers.
• Maintain stability in domestic fuel supplies during a period of global uncertainty.

During the restriction period, industrial, commercial, and institutional consumers were instructed to procure fuel through designated bulk supply channels instead of retail fuel stations.

Retail outlets were also directed to supply diesel only into vehicle fuel tanks or approved containers. Additionally, diesel purchases were temporarily capped at 200 litres per transaction, and violations were subject to action under the Essential Commodities Act.

Restrictions Later Withdrawn

After reviewing the country's fuel supply situation, the government lifted the temporary restrictions on June 29, 2026.

Normal fuel distribution resumed from July 1, allowing bulk consumers to purchase petrol and diesel through regular channels once again. The decision reflected improved domestic supply conditions and eased concerns over fuel availability.

What It Means Going Forward

The latest revision in windfall taxes reflects the government's effort to balance domestic energy security with changing international market dynamics. While higher export duties on diesel and aviation fuel could influence export economics for refiners, the reduction in petrol export duty provides some relief for exporters.

For ordinary consumers, however, the announcement does not alter the price they pay at fuel stations. Future changes in retail petrol and diesel prices will continue to depend on broader market factors, including international crude oil trends, refining costs, and pricing decisions by oil marketing companies.
