Customs exemption for specified yarn: table duty entry replaced with 'Nil', amending the earlier notification under Customs Act. The Central Government, invoking sub section (1) of Section 25 of the Customs Act, 1962, amends Notification No. 38/78 Customs by substituting the column (3) Table entry against Serial No. 6 with 'Nil', thereby changing the tariff treatment for specified yarn falling within Chapters 54 and 55.
