<h1>Windfall tax on diesel and ATF to be reviewed fortnightly as duties aim to secure domestic fuel supply.</h1> Special additional excise duty and export duties were imposed on diesel and aviation turbine fuel to discourage exports and secure adequate domestic supply. The windfall levy will be reviewed on a fortnightly basis, reflecting a dynamic adjustment mechanism linked to supply conditions and market developments. The duty changes were announced alongside a reduction in excise duty on petrol and diesel for domestic consumption to moderate price pressures and reduce underrecoveries for oil marketing companies.
