Remission of duty: waiver available for destroyed or lost manufactured goods before removal; Cenvat reversal clarified. Remission of duty waives excise on fully manufactured goods lost or destroyed before removal where loss results from natural causes, unavoidable accident, or goods are unfit for consumption, subject to Commissioner satisfaction and procedural proof; remission is available only for goods entered in the Daily Stock Account, may be granted despite insurance recovery, and is not equivalent to exemption. A rule amendment requires reversal of Cenvat credit where duty remission on final goods is ordered, reflecting administrative guidance and conflicting tribunal precedents reconciled by a circular endorsing reversal.
