Integrated tax substitution replaces prior additional duty references in customs exemption notifications, updating terminology and certain omissions. This notification amends multiple Customs exemption notifications by substituting references to the earlier 'additional duty leviable under section 3' with references to the 'integrated tax leviable under sub section (7) of section 3', and in specified cases also to the goods and services compensation cess, while omitting or deleting designated table entries and updating administrative terminology; the amendments take effect from the first day of July, 2017.
