Central Excise Rules establish a nationwide excise regulatory framework, superseding prior rules and coming into force upon notification. These Rules, made under the Central Excise Act, 1944, constitute the Central Excise Rules, 2017, extend to the whole of India, and supersede the Central Excise Rules, 2002 insofar as inconsistent; the notification specifies their commencement date and the statutory authority for their issuance.
