The Union government on Wednesday announced a reduction in the windfall tax levied on exports of several petroleum products, marking the latest recalibration of Delhi's energy pricing policy as global crude markets continue to swing and refiners grapple with narrowing profit margins.
Under the new structure, the export duty on diesel has been cut from ₹25 per litre to ₹20 per litre, while the levy on petrol has been slashed from ₹1.5 per litre to just ₹0.5 per litre. The government also revised the duty on Aviation Turbine Fuel (ATF), though specific numbers for that product were not immediately disclosed in the initial notification. The changes are expected to come into effect from the start of the current fiscal quarter.
Petroleum analysts said the reduction reflects the government's intent to shield domestic refiners from sustained margin pressure. Indian refining giants such as Reliance Industries and Hindustan Petroleum have seen their export profitability squeezed in recent months as international refined-product prices softened while crude oil remained elevated. By lowering the export duty, the government is effectively allowing companies to retain a larger share of the spread between domestic and international prices.
The windfall tax framework was originally introduced in 2022 when soaring global energy prices following geopolitical disruptions led to exceptional profits for refiners. Since then, the government has periodically adjusted the rates — sometimes raising them when margins were comfortable, and reducing them when domestic fuel prices came under strain.
Industry insiders noted that the diesel cut is particularly significant because diesel accounts for the largest share of India's petroleum product exports. A ₹5-per-litre reduction translates into a meaningful relief for exporters who move millions of litres monthly. The petrol duty cut, though smaller in absolute terms, was seen as symbolic of the government's willingness to revisit levy structures when conditions warrant.
The move comes at a time when India remains one of the world's largest exporters of refined petroleum products, shipping over 30 million metric tonnes annually to markets across Asia, Africa, and Europe. Policy shifts on export duties have direct implications for refinery utilization rates, domestic fuel availability, and ultimately the retail prices that Indian consumers pay at the pump.
