Amendment to Central Excise exemptions narrows eligible goods to those used in computer manufacture and revises the schedule entry. Amendment removes Sl. No. 133 from the exemption Table, restricts Sl. No. 255 to goods 'for use in manufacture of computer falling under the heading 8471,' and substitutes the entry in column(5) for Sl. No. 255, effectuating targeted modifications to Notification No. 12/2012 Central Excise under powers conferred by sub section (1) of section 5A of the Central Excise Act, 1944.
