Modvat credit and invisible processing loss principles protect inputs and waste, while PLA payment alone does not sustain duty demand.

Modvat credit on computers was denied because they were not used as parts of machinery employed in manufacture, and that disallowance was sustained. Duty on defective inputs retained in the factory was not justified merely because payment had been made through PLA, and the demand was set aside. Duty could not be demanded on waste and scrap arising from job work where only unavoidable invisible processing loss occurred, as Rule 57D protected credit and no shortage of the principal input was shown. Penalties were reduced and modified because the major duty demands failed, leaving only a limited sustained amount.

Issues: (i) whether Modvat credit on computers was admissible when they were not used as parts of machinery employed in manufacture; (ii) whether duty demand on defective inputs retained in the factory was sustainable merely because payment had been made through PLA; (iii) whether duty could be demanded for waste and scrap arising from job work where only invisible processing loss occurred; and (iv) whether the penalties required interference.

Issue (i): Whether Modvat credit on computers was admissible when they were not used as parts of machinery employed in manufacture.

Analysis: The credit on computers was denied on the footing that the computers were not used as parts of machinery employed for production or manufacture. That finding was not contested.

Conclusion: The denial of credit on computers was sustained and the assessee's challenge failed on this issue.

Issue (ii): Whether duty demand on defective inputs retained in the factory was sustainable merely because payment had been made through PLA.

Analysis: The defective inputs were found to be physically available in the factory at the time of investigation. There was no contrary finding that the inputs had been removed without reversal of credit. Mere debit in PLA did not justify confirmation of the demand on these facts.

Conclusion: The demand on defective inputs was set aside in favour of the assessee.

Issue (iii): Whether duty could be demanded for waste and scrap arising from job work where only invisible processing loss occurred.

Analysis: The processing of axles at the job worker's premises resulted in only an inherent loss of small particles which could not be collected and had to be treated as invisible waste. Rule 57D protected credit where part of the input was contained in waste or refuse, and there was no shortage of the principal input sent and received back. No duty demand could be sustained on such invisible loss.

Conclusion: The demand relating to waste arising from processing loss was set aside in favour of the assessee.

Issue (iv): Whether the penalties required interference.

Analysis: Since only the demand of Rs. 66,350 remained sustained, penalties attributable to the other disputed demands could not survive. The penalty of Rs. 1,00,000 was also found to be excessive in the circumstances.

Conclusion: The penalties were substantially reduced and modified.

Final Conclusion: The appeal succeeded in part, with the major duty demands deleted and the penalty confined to a reduced amount.

Ratio Decidendi: Where defective inputs remain available within the factory and processing results only in unavoidable invisible loss, duty demand is not sustainable and Modvat protection continues for the full quantity of input under the governing rule.
