CENVAT credit: new rules permit input duty credit with specified utilisation, compliance, documentation and transitional requirements. These rules prescribe the framework for claiming and using CENVAT credit on duties paid on inputs and specified additional duties for manufacturers and producers of excisable final products. They set eligibility, documentary foundations, time limits, job-worker and storage conditions, utilisation restrictions, refund formula for exports, option-based attribution between exempted and dutiable outputs with monthly provisional and annual reconciliation procedures, transitional transfer to the electronic credit ledger, transfer on change of ownership, and enforcement including recovery, confiscation and penalties.
