India increases windfall export taxes on petrol, diesel and aviation turbine fuel (ATF) effective 3 August 2026, according to reports citing government measures. Reuters and other outlets say the windfall tax on petrol exports rises to ₹3.5 per litre from ₹2.5 per litre. The levy on diesel exports is increased to ₹24 per litre from ₹15.5 per litre. For ATF, the export duty is raised to ₹22 per litre from ₹14.5 per litre. The changes apply to export shipments from 3 August and are described as part of a short-term adjustment period. One report notes that domestic fuel duties are left unchanged, while India reviews how global conflicts could affect supply chains. The revisions come after an earlier reduction in commercial LPG prices earlier in the month, which one outlet links to the broader pattern of government pricing and duty management. The reporting focuses on the updated export-duty rates and their effective date, without detailing any separate changes for imports or domestic retail fuel pricing.
