India Cuts Export Levies on Petrol, Diesel and ATF from 16 September 2026: Lower Windfall Tax and Nil Diesel Cess

India has reduced the special levies that sit on top of exported fuels, lowering the cost of shipping petrol, diesel and aviation turbine fuel (ATF) out of the country. Through a set of Central Excise notifications dated 16 September 2026, the government cut the Special Additional Excise Duty (SAED) — the so-called windfall tax — on petrol and diesel exports and took the Road and Infrastructure Cess (RIC) on diesel exports to nil. For refiners and petroleum-product exporters, this directly improves export economics on key fuel streams.

What Happened

Effective 16 September 2026, the changes are:

• SAED on petrol exports: ₹1.5 → ₹0.5 per litre, and SAED on diesel exports: ₹24 → ₹20 per litre (via Notification No. 49/2026-Central Excise). As the notification illustrates, on an export clearance of 10 lakh litres the revised rates reduce SAED liability by about ₹10 lakh on petrol and ₹40 lakh on diesel.
• Road and Infrastructure Cess (RIC) on diesel exports: ₹1 → Nil (via Notification No. 51/2026-Central Excise, G.S.R. 813(E)). This reverses an increase that had been introduced only two weeks earlier (Notification No. 48/2026-CE, dated 1 September 2026).
• SAED on ATF exports: reduced to ₹15 per litre (reported under Notification No. 50/2026-Central Excise).

These are levies on the export of petroleum products, not the basic customs duty on imports. The SAED on crude and fuels — introduced in July 2022 as a windfall tax — has been revised repeatedly in line with international crude and product margins; this round continues the recent easing.

Why / Background

The windfall-tax mechanism was designed to capture part of refiners' export margins when global product cracks were unusually high, while protecting domestic supply. As international margins and crude prices have normalised, the rationale for a high export levy weakens, and the government periodically trims the rates — sometimes fortnightly — to keep Indian fuel exports competitive and avoid discouraging product shipments. Taking the diesel export cess back to nil, so soon after raising it, reflects how finely these rates are tuned to market conditions.

Who Benefits

The direct beneficiaries are refiners and petroleum-product exporters — the companies clearing petrol, diesel and ATF for export — who see a lower per-litre levy and improved netbacks. Logistics providers, tankage operators and bunker/aviation-fuel suppliers linked to export flows benefit indirectly from firmer export volumes. The change does not alter pump prices for domestic consumers directly, as it operates on export clearances.

What Petroleum-Product Exporters Should Do Now

• Reprice export contracts and netback calculations using the revised ₹0.5/litre (petrol) and ₹20/litre (diesel) SAED and the nil diesel RIC from 16 September 2026.
• Confirm the clearance date drives the rate — apply the rate in force on the date of export clearance, and reconcile shipments that straddle the change.
• Track the fortnightly revision cycle — windfall-tax rates change frequently; build rate volatility into pricing and hedging.
• Update ERP and excise-accounting masters so the correct SAED/RIC rates flow into export documentation and duty computations.
• Keep documentation aligned across shipping bills, ARE forms and excise records to withstand audit.

The Bigger Picture

Frequent recalibration of fuel export levies is now a standard feature of India's petroleum trade policy — a lever the government pulls to balance domestic supply, refiner margins and export competitiveness as global markets move. For exporters, the practical takeaway is less about any single cut and more about process: the rate you plan around today can change in a fortnight, so pricing, hedging and accounting all need to track the notification cycle closely.

Frequently Asked Questions

Does this affect petrol and diesel prices at Indian pumps? Not directly. These are levies on exported fuel, not on domestic retail sales. Domestic pump prices are set separately.

Which exact rates apply now? From 16 September 2026: SAED of ₹0.5/litre on petrol exports, ₹20/litre on diesel exports, nil RIC on diesel exports, and ATF export SAED reported at ₹15/litre. Always apply the rate in force on your clearance date.

How often do these rates change? The windfall tax has historically been reviewed roughly every fortnight, tracking international crude and product margins, so expect further revisions.

Where do I find the official rates? In the Central Excise notifications on the CBIC website — Notifications No. 49, 50 and 51/2026-Central Excise and any subsequent amendments.

Conclusion

The 16 September 2026 cuts lower the SAED on petrol and diesel exports and zero out the diesel export cess, improving the economics of India's fuel exports. The amounts per litre are modest, but on export-scale volumes they matter — and because these rates move frequently, exporters should price, account and reconcile against the live notification each cycle.
