Modvat credit on fuel and revenue-neutral limitation bar shaped the duty demand outcome.

Furnace oil used as fuel in the melting process was treated as an input outside the scope of Rules 57C and 57CC for the relevant period, so reversal of Modvat credit under Rule 57C(2) was not sustainable. For molten wax cleared to a sister unit, the demand was held time-barred because the matter was revenue-neutral, as any duty paid would have been available as Modvat credit to the same corporate group, and the extended limitation under Section 11A could not be invoked absent intent to evade duty. The consequential penalty also failed.

Issues: (i) Whether Modvat credit taken on furnace oil used in the melting process was liable to reversal; and (ii) whether the demand of duty on molten wax cleared to the sister unit was time-barred in the absence of intent to evade duty.

Issue (i): Whether Modvat credit taken on furnace oil used in the melting process was liable to reversal.

Analysis: The furnace oil was used as fuel in the manufacturing process. During the relevant period, fuels used as inputs were expressly outside the category of inputs to which Rules 57C and 57CC applied. The demand for reversal rested on Rule 57C(2), but that provision could not be invoked against such fuel credit.

Conclusion: The demand for reversal of Modvat credit on furnace oil was not sustainable and was set aside.

Issue (ii): Whether the demand of duty on molten wax cleared to the sister unit was time-barred in the absence of intent to evade duty.

Analysis: The show-cause notice covered a period beyond the normal limitation. The duty, if paid, would have been available as Modvat credit to the sister unit of the same company, making the situation revenue-neutral. In such circumstances, absence of intent to evade duty was established and the extended period of limitation could not be invoked under Section 11A.

Conclusion: The demand of duty on molten wax was barred by limitation and was set aside.

Final Conclusion: The entire demand, including the consequential penalty, failed, and the assessee succeeded on both the substantive and limitation issues.

Ratio Decidendi: Credit on fuels expressly excluded from the relevant Modvat restrictions cannot be reversed, and where duty payment is revenue-neutral because it would be available as credit to a sister unit, the extended period of limitation is not invocable absent intent to evade duty.
