The notification amends Notification No.135/2016-Customs (N.T.) by inserting 'Authorised Public Undertaking' as a covered category and substituting the Explanation to define 'AEO' as Authorised Economic Operator and 'Authorised Public Undertaking' as an authorised public undertaking approved by the Directorate of International Customs under the Central Board of Indirect Taxes and Customs; the amendment takes effect from the date of publication in the Official Gazette.
