Centre Nearly Halves Diesel Export Duty to Rs 8.5 a Litre, Raises Petrol Levy Five-Fold

The government on Friday sharply reduced the windfall levy on diesel exports while raising the charge on outbound petrol shipments, in its latest fortnightly reset of fuel export taxes.

Under a Finance Ministry notification effective October 16, the Special Additional Excise Duty on diesel exports, including the road and infrastructure cess, falls to Rs 8.5 per litre from Rs 16. The levy on petrol exports rises to Rs 2.5 per litre from Rs 0.5, a five-fold increase from a low base. The duty on aviation turbine fuel (ATF) exports is unchanged at Rs 10.5 per litre.

The ministry said there is no change in excise rates on petrol and diesel sold in the domestic market, so retail pump prices are not directly affected.

Why the rates keep moving

The export levies were introduced on March 27 for diesel and ATF as the conflict in West Asia pushed up global fuel prices, and extended to petrol from May 16. They serve two purposes: discouraging refiners from shipping too much fuel abroad when overseas prices are attractive, which protects domestic supply, and capturing part of the extra margin that exporters earn when international product prices run well ahead of costs.

Because those margins swing with global crack spreads, the government reviews the rates every two weeks. The direction of this revision suggests that the premium refiners were earning on diesel exports has narrowed meaningfully, while petrol export margins have firmed. The levy has moved in both directions over the months; in early August, for example, petrol was charged Rs 3.5 per litre before being lowered again. Our earlier coverage tracked one of those upward revisions.

Who is affected

The change matters most for export-oriented private refiners, chiefly Reliance Industries and Nayara Energy, which ship large volumes of diesel to Europe, Africa and Asia. Diesel is by far the bigger export product for Indian refiners, so halving its levy is a meaningful relief that should more than offset the higher petrol charge for most exporters. State-run refiners, which sell most of their output domestically, are less exposed.

For the broader economy, the adjustment is a signal about how authorities read the supply situation. Cutting the diesel levy indicates the government is comfortable with domestic diesel availability heading into the post-monsoon peak for freight and farm demand, and is willing to let refiners capture more export income.

What to watch

The next revision is due at the end of the fortnight. With Brent crude still elevated and West Asia tensions unresolved, the rates could move again quickly. Exporters will also keep an eye on whether the government eventually phases out the levy altogether once global product markets normalise, something it has not yet signalled.

For households, the key point is unchanged: domestic excise duties and therefore pump prices stay where they are for now.
