Excise exemption amendment replaces a specified table entry with 'Steam', modifying the miscellaneous exemption framework under central excise. The Central Government, invoking powers under section 5A(1) of the Central Excise Act, amends Notification No. 4/97 by substituting the entry in the Table against serial number 25A, column (3), with the word Steam, thereby altering the textual description within the miscellaneous exemptions schedule.
