Customs amendment removes tariff exemption for machine tools, narrowing coverage of a prior exemption notification. The Central Government, invoking sub-section (1) of section 25 of the Customs Act, 1962, amends Notification No. 154/86-Customs by deleting, in the annexed Table against Sl. No. (i) column (2), item 54 and the entry relating thereto, thereby withdrawing the specified exemption entry for machine tools under the relevant headings.
