Supersession of earlier concessional import rules establishes a new statutory framework for concessional duty imports effective mid 2017. Rule 1 fixes the short title as the Customs (Import of Goods at Concessional Rate of Duty) Rules, 2017, declares commencement on the first day of July, 2017, records enactment under the Customs Act by the Central Government, and states these rules supersede the prior 2016 concessional import rules while saving prior acts and omissions.
