Excise exemption amendments update eligible outputs and linked inputs for factories in the North East, altering entitlement scope. The notification amends the excise-exemption table for factories in specified North East states by substituting S.No.12 (now listing cement and its inputs) and S.No.13 (modified starch or glucose with specified starch inputs), adding S.No.12A for cement clinker and limestone, and inserting S.No.15A (fatty acids or glycerine with specified oils) and S.No.15B (ferro alloys with chrome or manganese ore), thereby updating eligible outputs, their inputs and chapter classifications under Notification No. 33/99-Central Excise.
