Regulatory excise duty imposed on First Schedule goods by notification, cumulative with existing excise and retained by the Union. Imposes a regulatory duty of excise on goods listed in the First Schedule to the Central Excises Act, to be levied from dates specified by Central Government notification; different dates may apply by goods and notifications must be placed before Parliament. These regulatory duties are additional to existing excise duties, retained by the Union rather than distributed to States, and the Central Excises Act provisions and rules, including refunds and exemptions, apply as far as practicable to their levy and collection.
