Customs duty postponement extends implementation date for increased tariffs on specified imports from the USA. The amendment substitutes the date in the third proviso of Notification No.50/2017 Customs, replacing the earlier operative date with a later date to defer the implementation of increased customs duty on specified imports originating in the United States; the change is effected under section 25(1) of the Customs Act, 1962 and section 3(12) of the Customs Tariff Act, 1975 on public interest grounds.
