Excise schedule amendment revises tariff schedule references and inserts a new excise provision, enabling provisional tax collection effect. The Finance Act, 2012 amends excise-related references in the Finance Act, 2011 by altering section 73's opening portion to change First Schedule references, inserting a provision under the Excise heading as section 70A to provide for amendment of the Third Schedule, and substituting the Twelfth Schedule to replace references to the Central Excise Tariff Act with the Central Excise Act and the new cross-reference.
