Customs duty exemption: substitution of Nil entries for specified tariff items to extend exemptions to newspaper and magazine publishing. The Central Government, under section 25(1) of the Customs Act, 1962, amends Notification No. 21/2002-Customs by substituting the entries in column (4) of the Table for S. No. 154, S. No. 154A and S. No. 156 with the entry 'Nil', thereby recording zero duty for those tariff items by Notification No. 13/2009.
