Customs Tariff: repeal preserves prior acts, notifications, rules and orders unless inconsistent with the new Act. Section 12 repeals the Indian Tariff Act, 1934 and the Indian Tariff (Amendment) Act, 1949, and saves prior actions, notifications, rules and orders made under those Acts by deeming them valid under the Customs Tariff Act, 1975 so long as they are not inconsistent with that Act and until superseded.
