Customs and Excise duty changes introduce immediate tariff revisions, new optional levies on garments and jewellery, and procedural simplifications. Finance Bill, 2016 notifications effective 1 March 2016 and provisional declarations introduce immediate Customs and Central Excise duty changes, targeted exemptions subject to actual user conditions, and procedural simplifications. Central Excise adds optional RSP linked levies on branded readymade garments (2% without CENVAT or 12.5% with CENVAT) and on specified articles of jewellery (1% without CENVAT or 12.5% with CENVAT) with revised tariff value, SSI thresholds and simplified registration/return rules. Customs changes rationalise BCD/CVD/SAD across many chapters, amend export duties, and prescribe industry specific exemptions and conditional concessions.
