Excise notification amendment extends compliance deadline to mid-April under relevant procedural rule and Additional Duties Act. The Central Government, under rule 8(1) of the Central Excise Rules, 1944 and sub section (3) of section 3 of the Additional Duties of Excise Act, 1957, amends Notification No. 34/87 Central Excises by substituting the date in the last proviso, formally replacing the earlier specified expiry date with a later date.
