Modvat and Cenvat credit limits on diverted fuel inputs, captive gas use, interest, penalty, and process loss clarified on remand.

Modvat/Cenvat credit on LSHS and additive fuel oil used to generate electricity and steam diverted outside the factory was treated as inadmissible for the period before 1-3-1997, and remained confined under Rule 57B(iv) to electricity or steam used within the factory. Duty demand on hydrogen gas captively used for steam supplied to a sister unit was rejected. Interest was held unsustainable where the relevant provision was not properly invoked, while penalty required fresh consideration in light of the assessee's disclosures and the differing departmental norms. Demand arising from AC-to-DC conversion loss was treated as unsustainable as an inevitable process loss. The matter was remanded for fresh adjudication and re-quantification where necessary.

Issues: (i) Whether Modvat/Cenvat credit on LSHS and additive fuel oil used for generation of electricity and steam diverted outside the factory was admissible; (ii) whether duty demand on hydrogen gas captively used in producing steam cleared to a sister unit was sustainable; (iii) whether interest and penalty could be sustained in the absence of proper invocation and on the facts of the case; and (iv) whether the demand on account of power loss in conversion from AC to DC power was sustainable.

Issue (i): Whether Modvat/Cenvat credit on LSHS and additive fuel oil used for generation of electricity and steam diverted outside the factory was admissible.

Analysis: Credit under Rule 57A(1) was available only where inputs were used in or in relation to the manufacture of final products cleared on payment of duty. The Tribunal held that the inputs used for generation of electricity or steam which were diverted outside the factory did not satisfy that requirement for the period prior to 1-3-1997. It further held that, after the introduction of Rule 57B(iv), credit remained confined to electricity or steam used within the factory of production, and the impugned demands on LSHS and additive fuel oil were supported by the statutory scheme.

Conclusion: Credit on LSHS and additive fuel oil relatable to electricity and steam diverted outside the factory was not admissible, and the demand on that count was upheld in principle.

Issue (ii): Whether duty demand on hydrogen gas captively used in producing steam cleared to a sister unit was sustainable.

Analysis: The Tribunal applied the principle that intermediate products removed to sister units manufacturing dutiable final products did not warrant a separate duty demand in the manner proposed. On that basis, the duty demand raised on hydrogen gas was found unsustainable.

Conclusion: The duty demand on hydrogen gas was rejected.

Issue (iii): Whether interest and penalty could be sustained in the absence of proper invocation and on the facts of the case.

Analysis: The Tribunal held that interest could not be sustained where the relevant statutory provision had not been properly invoked in the show cause notices. On penalty, it found deliberate withholding of information relevant to the inadmissible credit, but also noted that penalty was not justified for demands arising from differing norms adopted by the assessee and the department. It therefore left the matter to fresh adjudication along with re-quantification and reconsideration of the period-wise position.

Conclusion: Interest was not sustainable as framed, while penalty required reconsideration in fresh adjudication.

Issue (iv): Whether the demand on account of power loss in conversion from AC to DC power was sustainable.

Analysis: The Tribunal treated the conversion loss as an inevitable process loss and held that credit could not be denied merely on that basis.

Conclusion: The demand relating to AC to DC conversion loss was not sustainable.

Final Conclusion: The appeals were allowed by way of remand, and the original authority was directed to re-adjudicate the cases afresh in light of the Tribunal's findings, including re-quantification where necessary.
