Modvat credit on inherent manufacturing loss cannot be denied merely because no visible waste product is left.

Rule 57D of the Central Excise Rules, 1944 protects Modvat credit from denial where inputs are consumed in manufacture and suffer inherent process loss, even if no physically identifiable waste product emerges. Inputs such as ingots and billets that diminish during melting and burning are treated as part of normal manufacturing loss; the absence of visible waste does not, by itself, justify reversal of credit or demand of duty. On that basis, reasonable percentage loss in such processes was treated as covered by Rule 57D, and denial of Modvat credit was not sustainable.

Issues: Whether Modvat credit could be denied and duty demanded on inputs lost during the melting and burning process when no physical waste product emerged, and whether such loss was covered by Rule 57D of the Central Excise Rules, 1944.

Analysis: Rule 57D of the Central Excise Rules, 1944 protects credit already allowed from being denied merely because part of the inputs is contained in waste arising during manufacture, or because the inputs themselves become waste in or in relation to manufacture of the final product. Where inputs such as ingots and billets diminish in quantity because of burning and melting, the loss is an inherent process loss and does not require the existence of a physically demonstrable waste product. In such circumstances, the absence of visible waste does not justify denial of credit or demand of duty, and the authorities were justified in treating a reasonable percentage loss as covered by the rule.

Conclusion: The denial of Modvat credit was not sustainable, and the appeal by the Revenue failed.
