Modvat credit and exempt waste removal govern duty treatment of spent nickel catalyst cleared after manufacture.

Spent nickel catalyst cleared after use in manufacture was treated as waste or residue, not as nickel catalyst in its original form. Rule 57D(1) protected Modvat credit on inputs contained in waste or refuse, and Rule 57F(4) allowed removal of such waste with duty, if any, to be determined on the date of clearance. Because the spent catalyst fell under Chapter 26 and was wholly exempt under Notification No. 19/88-C.E. on the relevant date, no central excise duty was payable on its removal. The duty demand and penalty were therefore not sustainable.

Issues: Whether spent nickel catalyst, cleared as residue after use in manufacture, was liable to central excise duty despite the availment of Modvat credit on the input nickel catalyst and the exemption under Notification No. 19/88-C.E.

Analysis: The residue cleared by the assessee was not nickel catalyst as such but waste obtained after its use in the manufacture of the final product. Rule 57D(1) of the Central Excise Rules protected Modvat credit in respect of inputs contained in waste or refuse. Rule 57F(4) permitted removal of waste arising from processing of inputs, with duty, if any, determined on the date of removal. Since spent nickel catalyst fell within Chapter 26 and was wholly exempt from duty under Notification No. 19/88-C.E. on the relevant date, no duty was payable on its clearance.

Conclusion: The demand of duty and penalty could not be sustained, and the appeal was allowed in favour of the assessee.
