Compounded levy scheme limits makers to machine based fixed duty, bars cenvat credit and export rebate. The Compounded Levy Scheme imposes capacity based fixed excise duty determined by notified rates applied to the maximum number of relevant machines installed during the three calendar months preceding application; participation is elective but binding for the declared period, requires specified application and intimation procedures, and excludes export rebate, SSI exemption where specified, and cenvat credit.
