Appeal form revisions require expanded appellant identifiers and a standardized alphanumeric order code to improve case processing. Revised Central Excise, Customs and Service Tax appeal forms, effective 1 June 2013 (old forms permitted until 31 August 2013), require expanded appellant identifiers (Assessee Code/PAN/UID, Location Code, contact details), Customs-specific IEC and Port Code, Service Tax Premises Code, separate entries for duty/fine/penalty/interest, subject codes for bunching, and a mandatory 21-character alphanumeric order identifier encoding Commissionerate, officer type, serial number, financial year and order date for Commissionerate wise indexing.
