Modvat scrap duty lies with the principal manufacturer, while duty demand and penal consequences must be tested on verified facts.
Under the Modvat scheme, waste and scrap arising from credit-availing inputs sent to a job worker attracted duty in the hands of the principal manufacturer who had taken the credit, not the job worker. The extended period of limitation was held invocable on the facts because full disclosure was not established. However, the duty demand had to be recomputed after verifying the claim that part of the inputs had already suffered duty, so the quantum required fresh examination. Penalty under Section 11AC and interest under Section 11AB were set aside because the dispute period was prior to September 1996 and those provisions were not applicable.
Issues: (i) Whether duty on waste and scrap arising from inputs sent to a job worker under the Modvat scheme was payable by the principal manufacturer or by the job worker; (ii) whether the extended period of limitation was invocable; (iii) whether duty had to be recomputed after excluding duty-paid inputs sent for job work; (iv) whether penalty under Section 11AC of the Central Excise Act, 1944 and interest under Section 11AB of the Central Excise Act, 1944 were sustainable.
Issue (i): Whether duty on waste and scrap arising from inputs sent to a job worker under the Modvat scheme was payable by the principal manufacturer or by the job worker.
Analysis: The scheme under Rule 57F(2) and Rule 57F(5) of the Central Excise Rules, 1944 was treated as a self-contained regime governing credit-availing inputs sent for job work. The expression "appropriate duty" in the context of scrap generated from such inputs was held to refer to the duty liability of the main manufacturer who had taken credit and sent the inputs for processing, not to the job worker who merely processed them.
Conclusion: Duty on the scrap generated by the job worker was payable by the principal manufacturer and not by the job worker.
Issue (ii): Whether the extended period of limitation was invocable.
Analysis: The record disclosed that the appellant had not established full disclosure sufficient to defeat the invocation of the longer limitation period. The statutory scheme required proper accounting for inputs and the scrap arising therefrom, and the plea against extended limitation was not accepted on the facts.
Conclusion: The extended period of limitation was invocable.
Issue (iii): Whether duty had to be recomputed after excluding duty-paid inputs sent for job work.
Analysis: A specific factual claim was raised that out of the total quantity sent for processing, a substantial quantity had already suffered duty. Since no finding had been returned on that aspect, the demand could not be sustained without verification of the claim. The duty on scrap had therefore to be recalculated after examining whether duty had already been paid on the identified quantity of inputs.
Conclusion: The duty demand required recalculation after verifying the appellant's claim regarding duty-paid inputs.
Issue (iv): Whether penalty under Section 11AC of the Central Excise Act, 1944 and interest under Section 11AB of the Central Excise Act, 1944 were sustainable.
Analysis: Since the dispute period was prior to September 1996, the statutory basis for penalty and interest was not available for the period in question. The appellant's liability was therefore not visited with penalty or interest under those provisions.
Conclusion: Penalty under Section 11AC of the Central Excise Act, 1944 and interest under Section 11AB of the Central Excise Act, 1944 were set aside.
Final Conclusion: The appeal succeeded only in part: the duty liability on scrap was upheld in principle, but the quantum required fresh verification and the penal and interest demands were annulled, with the matter sent back for recomputation.
Ratio Decidendi: Under the Modvat scheme, when inputs taken on credit are sent to a job worker, duty on waste and scrap generated from those inputs is fastened to the principal manufacturer who availed the credit, and the duty demand must be computed on a properly verified factual basis.
