Marketable waste under a specific tariff entry is excisable, but non-manufactured spent catalyst is not.

Spent fuller earth was treated as excisable because the Central Excise Tariff Act, 1985 contains a specific entry for residues arising from treatment of fatty substances, and marketable waste or residue covered by that entry is liable to duty; it was classified under sub-heading 1507.00. Spent nickel catalyst was treated as not excisable because it was not regarded as manufactured into a new and different article, so no tariff classification arose. The result was mixed: duty liability attached to spent fuller earth, while spent nickel catalyst remained outside excise.

Issues: (i) whether spent fuller earth is excisable and, if so, the proper tariff classification; (ii) whether spent nickel catalyst is excisable and, if so, the proper tariff classification.

Issue (i): Whether spent fuller earth is excisable and, if so, the proper tariff classification.

Analysis: The earlier Tribunal decisions treating spent earth as non-excisable under the old tariff were distinguished on the ground that the Central Excise Tariff Act, 1985 contains a specific entry for residues resulting from the treatment of fatty substances. Applying the later tariff structure and the reasoning that marketable waste or residue falling within a specific entry is liable to duty, spent fuller earth was held to answer that description.

Conclusion: Spent fuller earth is excisable and falls under sub-heading 1507.00 of the Central Excise Tariff Act, 1985, in favour of Revenue.

Issue (ii): Whether spent nickel catalyst is excisable and, if so, the proper tariff classification.

Analysis: Following the Tribunal's earlier view that spent nickel catalyst is not manufactured and does not become a new and different article in the course of manufacture, the item was treated as not excisable. On that footing, no tariff classification could be made.

Conclusion: Spent nickel catalyst is not excisable and its classification does not arise, in favour of Assessee.

Final Conclusion: The order was modified to hold spent fuller earth dutiable under the specified tariff entry while denying excisability to spent nickel catalyst, resulting in a mixed outcome.

Ratio Decidendi: Under the Central Excise Tariff Act, 1985, a waste or residue is excisable if it is marketable and specifically covered by a tariff entry, but an item that is not the result of manufacture is not excisable merely because it emerges in the manufacturing process.
