CENVAT credit on inputs in job-worker waste and scrap need not be reversed absent an express return requirement.

The post-2000 job-work CENVAT scheme under Rule 4(5)(a) did not expressly require waste and scrap generated at the job worker's premises to be returned to the principal manufacturer, and credit on inputs contained in such waste and scrap remained admissible. A Board circular dated 3.4.2000 was relied on to confirm that the debit requirement applies only to inputs or capital goods not received back within 180 days, not to waste, refuse or by-products. On that basis, no reversal of CENVAT credit was payable for non-return of the waste and scrap, and the related demand, interest and penalty could not survive.

Issues: Whether CENVAT credit attributable to inputs contained in waste and scrap generated at the job worker's premises and not received back by the principal manufacturer is required to be reversed.

Analysis: The dispute turned on the scope of Rule 4(5)(a) of the Cenvat Credit Rules, 2004, read with the earlier job-work regime under Rule 57F(5) of the Central Excise Rules, 1944. The Tribunal noted that the post-2000 scheme only required the processed inputs to be received back within the stipulated period and did not contain any express stipulation requiring return of waste and scrap generated at the job worker's end. It also relied on the Board's circular dated 3.4.2000, which clarified that CENVAT credit remains admissible on the inputs contained in waste, refuse or by-products and that the debit requirement applies only to inputs or capital goods not received back within 180 days.

Conclusion: No reversal of CENVAT credit was payable on the inputs contained in waste and scrap generated at the job worker's premises and not returned to the principal manufacturer.

Final Conclusion: The demand, interest and penalty could not survive, and the appeal was allowed with consequential relief in accordance with law.

Ratio Decidendi: In the absence of an express statutory requirement under the post-2000 job-work provisions, CENVAT credit cannot be reversed merely because waste and scrap generated at the job worker's premises were not received back, where the credit relates to inputs contained in such waste and scrap.
