Cenvat credit on waste-related bio-compost processing need not be reversed; defective notice made the demand unsustainable.

Credit on inputs and input services used in dutiable manufacture was held to remain available where waste or residue was later converted into bio-compost and cleared without duty; a presumptive reversal or payment under the excise rule was not warranted on that basis. The demand was also found unsustainable because the show cause notice did not identify the specific inputs or input services allegedly used in generating the press mud or bio-compost, making the notice defective for want of a clear factual foundation.

Issues: (i) whether credit already taken on inputs and input services was required to be reversed, or presumptive amount paid, merely because waste products were converted into bio-compost and cleared without duty; (ii) whether the demand was sustainable when the show cause notice did not specify the input or input services allegedly used in generating the press mud/bio-compost.

Issue (i): Whether credit already taken on inputs and input services was required to be reversed, or presumptive amount paid, merely because waste products were converted into bio-compost and cleared without duty.

Analysis: The settled legal position treated waste arising in manufacture as not attracting duty merely because it was cleared without payment of duty. On that principle, Rule 57D protected the assessee's entitlement to retain the credit on inputs used in the manufacture of dutiable final products, and Rule 57CC did not apply merely because the waste was further processed into an exempt product. The liability to pay a presumptive amount could not be fastened in such circumstances.

Conclusion: The issue was decided in favour of the assessee, and no reversal of credit or payment under Rule 57CC was warranted on these facts.

Issue (ii): Whether the demand was sustainable when the show cause notice did not specify the input or input services allegedly used in generating the press mud/bio-compost.

Analysis: The notice failed to identify which inputs or input services were said to have resulted in the generation of press mud later converted into bio-compost. That deficiency went to the root of the demand and rendered the notice defective for want of a clear foundation for the allegation.

Conclusion: The demand was unsustainable on account of the defective show cause notice, in favour of the assessee.

Final Conclusion: The impugned order could not survive, and the appeal succeeded with relief to the appellant.

Ratio Decidendi: Credit on inputs used in dutiable manufacture is not required to be reversed, and no presumptive liability arises under the relevant excise rule, merely because waste or residue is cleared without duty or further processed into an exempt product; a demand founded on an unspecified and defective notice is unsustainable.
