Customs exemption amendment removes 'steel powders' from the exemption table, narrowing the scope of the relevant notification. Amendment deletes the entry 'steel powders' from the list of goods in the Table to Notification No. 151 Customs (15 July 1977) under the powers of section 25(1) of the Customs Act, 1962, thereby removing that item from column (2) of the annexed Table and narrowing the exemption coverage.
