Residual by-products lacking distinct commercial identity are not dutiable under the residuary excise tariff item.

Aluminium dross and skimmings arising during melting and sheet/circle manufacture were treated as refuse scum or rubbish thrown out in the course of production, not as a new and distinct excisable product. Because they did not emerge from treatment, labour, or manipulation into an article with separate name, character, or use, they were held outside Tariff Item 68. The assessment fastened on that duty liability could not stand. The reasoning followed the Bombay High Court view on the same commodity and aligned with later Tribunal orders adopting the same principle.

Issues: Whether aluminium dross and skimmings generated in the process of melting aluminium and converting it into sheets and circles were liable to duty under Tariff Item 68 of the Central Excise Tariff.

Analysis: The material was held to be refuse scum or rubbish thrown out in the course of manufacture and not the product of treatment, labour, or manipulation resulting in a new and different article with a distinct name, character, or use. The reasoning followed the binding Bombay High Court decision on the same commodity and was consistent with later Tribunal orders taking the same view.

Conclusion: Aluminium dross and skimmings were not liable to duty under Tariff Item 68, and the assessment adopting that duty liability could not stand.

Ratio Decidendi: Residual by-products that do not emerge as a new and distinct excisable article with a separate commercial identity are not chargeable to duty under the residuary tariff item.
