Govt announces major hikes in export duties on diesel, jet fuel to ensure domestic fuel availability
The government sharply hiked export duties on high-speed diesel to ₹55.5 per litre and on aviation turbine fuel (ATF) to ₹42 per litre
The hike reversed the earlier zero-duty regime and represents a sharp increase from prior rates of ₹21.5/litre (diesel) and ₹29.5/litre (ATF)
Export duty on petrol was left unchanged at nil, signalling confidence in domestic petrol supply
The primary objective is supply management — preventing exporters from diverting fuel to international markets for higher margins as global prices surged due to the West Asia conflict
The government simultaneously cut domestic excise duty on petrol and diesel by ₹10/litre to cushion retail consumers
Export Duties — Constitutional and Legal Framework
Export duties are levied by the Union Government under Entry 83 of List I (Union List), Schedule VII of the Constitution, which empowers Parliament to legislate on "duties of customs including export duties." The Customs Tariff Act, 1975 specifies the applicable rates through its Second Schedule (covering exports), while the Customs Act, 1962 provides the administrative machinery for levy and collection. CBIC (Central Board of Indirect Taxes and Customs) issues notifications for rate changes.
Key Details
- Export duties can be ad valorem (percentage of value) or specific (fixed per unit of quantity — as in this case, ₹/litre)
- The Directorate General of Trade Remedies (DGTR) under the Ministry of Commerce investigates trade remedy cases; export duty changes on petroleum products are, however, notified directly by MoF/CBIC under emergency economic powers
- SEZ refineries (e.g., Reliance's Jamnagar SEZ) were historically exempt from windfall gains levies under the SEZ Act, 2005 — a contentious carve-out
The export duty hike on diesel and ATF is a specific-duty intervention under customs law, designed to make exports economically unviable relative to domestic supply, thereby redirecting fuel availability inward.
Windfall Tax and Resource Nationalism in Energy Policy
A windfall tax is a one-time or temporary levy imposed on companies when extraordinary profits arise from external circumstances (e.g., war-driven price spikes) rather than business efficiency. India introduced a windfall gains tax on domestic crude and petroleum product exports in July 2022 after the Russia-Ukraine war triggered a global energy price surge. The tax was reviewed every fortnight based on global crude prices and was eventually scrapped in December 2024 once price differentials normalised.
Key Details
- Windfall taxes are not unique to India — the EU, UK, and several countries used similar instruments post-2022 energy shock
- The economic rationale: when international prices rise sharply, refiners have an incentive to export rather than sell domestically, creating domestic shortages even when crude supplies are adequate
- The export duty functions as a price equalisation mechanism, removing the arbitrage between domestic and export markets
The reimposition of export duties on diesel and ATF in April 2026 mirrors the 2022 windfall tax episode — a geopolitically induced global price spike leading to the same domestic supply-security concern.
Energy Security and the Strait of Hormuz
The Strait of Hormuz is the world's most critical oil chokepoint, connecting the Persian Gulf to the Gulf of Oman. About 20-21 million barrels per day of crude oil and petroleum products pass through it — roughly 20% of global oil trade. India imports about 85% of its crude oil needs, with a significant share transiting through this strait. Disruptions trigger both price spikes and supply uncertainty.
Key Details
- India's major crude suppliers — Saudi Arabia, UAE, Iraq, Kuwait — all route shipments through the Strait of Hormuz
- India has begun diversifying through alternate routes and increased Russian crude purchases (which do not transit the strait)
- Strategic Petroleum Reserve (SPR): India has underground reserves at Vishakhapatnam, Mangaluru, and Padur (total ~5.33 million tonnes) to buffer short-term supply shocks
The West Asia conflict that triggered global fuel price surges incentivised Indian refiners to export rather than supply domestically, making the export duty hike a direct energy security measure.
- Diesel export duty raised from ₹21.5/litre to ₹55.5/litre (a 158% increase)
- ATF export duty raised from ₹29.5/litre to ₹42/litre
- Petrol export duty unchanged at nil
- Domestic excise duty cut by ₹10/litre simultaneously to protect retail consumers
- India imports ~85% of crude oil; significant share transits Strait of Hormuz
- India's Strategic Petroleum Reserve capacity: ~5.33 million tonnes across 3 locations
- Windfall tax on petroleum exports was scrapped in December 2024 before being effectively revived in April 2026 via export duty route
