Road and infrastructure cess on petrol and diesel introduced, with notifications modifying excise duty and temporary exemptions. A Road and Infrastructure Cess on petrol and diesel was imposed in Budget 2018-19 and made immediately effective by provisional collection. Central Excise notifications rescind prior exemptions, reduce certain basic excise rates, incorporate the new cess into the appropriate duty for ethanol blended petrol and bio diesel, and provide temporary exemptions pending enactment. Amendments clarify that exemptions do not apply to goods manufactured on or before 01.02.2018 and cleared on or after 02.02.2018; targeted 50% relief for specified North East refinery clearances and exemptions for ethanol blends and bio diesel are addressed.
