The Union government has implemented a revision in the windfall tax structure applied to petroleum exports, effective from 16 October. According to the latest official notification, the special additional excise duty (SAED) and road and infrastructure cess on diesel exports have been significantly reduced, falling to ₹8.50 per litre from the previous rate of ₹16 per litre. Conversely, the levy on petrol exports has been upwardly adjusted to ₹2.50 per litre, moving up from the earlier rate of ₹0.50 per litre.
These periodic adjustments follow a consistent policy framework established by the government to respond to fluctuations in the global energy market. While the export duties on diesel and petrol have been modified, the levy on aviation turbine fuel (ATF) remains stable at ₹10.50 per litre. The government reviews these rates every fortnight to account for shifting dynamics in crude oil pricing and international geopolitical tensions.
The windfall tax mechanism was originally introduced by the authorities on 27 March to manage the impact of regional instability in West Asia on global oil supplies. The primary objective of these levies is to discourage domestic refiners from prioritizing exports over local demand during periods of high global prices. By taxing the price differential between domestic and international markets, the government aims to ensure that the domestic availability of essential petroleum products remains secure for Indian consumers.
Although India functions as a net importer of crude oil—sourcing approximately $123 billion worth of crude annually—it also maintains a significant presence as an exporter of refined petroleum products. Data indicates that India exports nearly $45 billion worth of items including petrol, diesel, and jet fuel. Reliance Industries serves as the nation’s largest exporter of these products, supported by various state-run oil marketing companies that also maintain a substantial footprint in international trade.
India currently holds the position of the world’s seventh-largest exporter of petroleum products, supported by a robust refining infrastructure. With a total crude refining capacity exceeding 258 million tonnes, the country ranks fourth globally in this sector. This industrial capability is increasingly focused on meeting rising domestic demand, which reached a record 243 million tonnes in the fiscal year 2026, compared to 61.43 million tonnes in exports during the same period, according to figures from the Petroleum Planning and Analysis Cell (PPAC).
The recent adjustments occur against a backdrop of heightened market volatility. Tensions in West Asia have contributed to a nearly 10% increase in oil prices over the preceding two-week period. As of the latest market data, the December contract of Brent crude on the Intercontinental Exchange was trading at $105.5 per barrel. While these market fluctuations create pressure for energy refiners, the government maintains that there is no change in the existing duty rates for petrol and diesel cleared specifically for domestic consumption.
Moving forward, the government is expected to continue its practice of fortnightly reviews to monitor the impact of these levies on trade balances and domestic supply stability. These revisions are essential to navigate the challenges posed by fluctuating crude costs and to balance India’s status as a major global refiner with the critical need for local fuel availability. Observers will be closely monitoring how future global market conditions influence the next cycle of duty adjustments planned by the ministry.
