india raises export duty petrol cuts those diesel and aviation fuel 4176981

India adjusts export duties on refined petroleum products, increasing petrol export duty while cutting diesel and aviation fuel duties. This directly impacts Indian refiners' margins: higher petrol export duty reduces netback for petrol exports, while lower diesel and ATF duties improve export competitiveness. The bi-weekly revision mechanism links duties to international prices, creating periodic margin volatility. Domestic retail prices recently increased, but excise duties unchanged. The mechanism is regulatory (export tax) affecting refining margins and trade flows.
