Tariff entry alone does not make zinc dross excisable; pre-amendment galvanization residue escaped central excise duty.

A tariff listing of zinc dross was held insufficient, by itself, to make galvanization residue excisable before the statutory amendment to Section 2(d) of the Central Excise Act, 1944. Prior judicial views on zinc dross and skimmings, together with the absence of any legal fiction treating the residue as manufactured goods before the amendment, showed that the product was neither manufactured nor marketable for excise purposes during the relevant pre-May 2008 period. On that basis, the duty demand, interest, and penalty could not stand, and consequential relief followed.

Issues: Whether zinc dross arising during galvanization was excisable and marketable for the period prior to May 2008 notwithstanding its specific tariff entry.

Analysis: The tariff listing of zinc dross by itself was held insufficient to establish excisability. The prior judicial view on zinc dross and skimmings, the absence of any legal fiction treating such residue as manufactured goods before the statutory amendment, and the Board circular clarifying that such waste products became excisable only after the amendment to Section 2(d) of the Central Excise Act, 1944 were relied upon. The cited decisions on other products were treated as inapplicable because they arose from different factual settings and did not govern zinc dross.

Conclusion: Zinc dross generated during galvanization was not liable to excise duty for the period prior to May 2008, and the duty demand, interest, and penalty could not stand.

Final Conclusion: The appeals succeeded and the impugned order was set aside, with consequential relief.

Ratio Decidendi: A mere tariff entry does not make a residue or waste product excisable; before the statutory amendment deeming such goods marketable, zinc dross from galvanization was neither manufactured nor excisable.
