What Happened
- The Centre sharply raised export duties on diesel from ₹21.5 per litre to ₹55.5 per litre and on aviation turbine fuel (ATF) from ₹29.5 per litre to ₹42 per litre with immediate effect.
- The revisions were notified on April 11, 2026, through notifications issued by the Department of Revenue.
- Export duty on petrol was kept at nil.
- The move follows a broader revision in domestic fuel taxation — Special Additional Excise Duty (SAED) on high-speed diesel raised to ₹24 per litre and Road and Infrastructure Cess raised to ₹36 per litre.
- The hike is aimed at preventing domestic fuel from being diverted for export as global crude prices rose in the aftermath of a US-Israel-Iran military exchange, while a temporary two-week ceasefire announced on April 8, 2026 has eased some market pressure.

Windfall Tax and Special Additional Excise Duty (SAED)
A windfall tax is a one-time tax levied on companies or sectors earning exceptionally high profits due to external, unearned circumstances (such as a sudden commodity price spike) rather than business innovation or investment. In India, the windfall tax on fuel exports is operationally implemented through the Special Additional Excise Duty (SAED) mechanism under the Central Excise Act. First introduced in July 2022 — when Russian oil discounts created asymmetric export incentives for Indian refiners — it is adjusted fortnightly based on international oil price benchmarks by the Central Board of Indirect Taxes and Customs (CBIC). It was scrapped in December 2024 and re-introduced in March 2026 as West Asia tensions escalated.
- Legal basis: Special Additional Excise Duty (SAED) under Central Excise Act
- Reviewing authority: CBIC, reviewed fortnightly
- First introduced: July 2022 (Russia-Ukraine oil price shock)
- Scrapped: December 2024; re-introduced: March 2026 (West Asia crisis)
- April 2026 diesel export duty: ₹55.5/litre (₹18.5 SAED + AED + cess components)
- ATF export duty: ₹42/litre (entirely as SAED)
- Petrol export duty: nil
- SEZ exemption: SAED does not apply to exports from SEZ refineries (e.g., Reliance's Jamnagar SEZ unit)
Connection to this news: The sharp hike in export duties from ₹21.5 to ₹55.5/litre for diesel reflects the government's use of the SAED mechanism as a supply management tool — prioritising domestic fuel availability over refiner export revenues.
Export Duty as a Supply Management Instrument
Export duties are a category of fiscal intervention where the government levies a tax on goods being exported to discourage outflows, retain domestic supply, and moderate domestic prices. Under the Customs Act, 1962, the Central Government is empowered to impose, vary, or exempt export duties through notifications. Export duties are the mirror instrument of import duties — while import duties protect domestic producers from cheap foreign competition, export duties protect domestic consumers from supply diversion in times of scarcity.
- Legal authority: Customs Act, 1962 (for export duties); Central Excise Act (for SAED/AED on domestically produced and exported goods)
- Issuing authority: Department of Revenue via gazette notifications
- ATF market context: Domestic airlines are not directly affected by the export duty; the levy targets refiners exporting to foreign airlines and fuel traders
- Domestic aviation fuel pricing in India follows a deregulated market since 2002; ATF is priced based on international crude benchmarks plus taxes
Connection to this news: The ATF export duty hike specifically targets the arbitrage opportunity for Indian refiners to export jet fuel at high international prices while domestic airlines face supply pressure.
Oil Marketing Companies (OMCs) and Energy Security
India's three major state-owned Oil Marketing Companies — Indian Oil Corporation (IOC/IOCL), Bharat Petroleum (BPCL), and Hindustan Petroleum (HPCL) — control over 90% of LPG and fuel distribution infrastructure. They absorb under-recoveries when regulated retail fuel prices are below cost, with the government providing periodic subsidy compensation. In the current West Asia disruption scenario, OMCs face a dual squeeze: higher import costs and competitive pressure from private refiners diverting product to higher-priced export markets.
- IOC, BPCL, HPCL together control over 90% of India's fuel retail and LPG distribution
- FY 2026-27 LPG subsidy approved for OMCs: ₹30,000 crore
- India imports roughly two-thirds of its LPG demand (rest from domestic refineries)
- The West Asia crisis of 2026 (US-Israel strikes on Iran, Strait of Hormuz tensions) is the immediate trigger for the export duty hike
Connection to this news: The export duty hike directly benefits OMCs by reducing incentives for private refiners to export, thereby increasing the volume available for domestic sale and stabilising market supply.
