Aluminium scrap classification under excise duty turned on crude-form tariff coverage and later specific entry under Tariff Item 68.

Aluminium scrap was held outside Tariff Item 27(a) because an entry confined to the crude or raw form of a metal does not extend to scrap. Duty liability arose only from 1-3-1975 under Tariff Item 68, and the later insertion of Tariff Item 27(aa) was treated as confirming specific coverage of waste and scrap thereafter. The decision therefore recognised no duty for the earlier period in the absence of a specific charging entry, with partial relief to the assessee.

Issues: Whether aluminium scrap was chargeable to central excise duty under Tariff Item 27(a), whether it became dutiable only under Tariff Item 68 from 1-3-1975, and whether the subsequent amendment introducing Tariff Item 27(aa) affected the position.

Analysis: The classification dispute was resolved by applying the reasoning adopted in decisions construing the analogous expression "copper in crude form" under Tariff Item 26A. On that basis, aluminium scrap was held not to fall within Tariff Item 27(a), because crude form connotes the raw form of the metal and does not comprehend scrap. The introduction of Tariff Item 68 from 1-3-1975 was treated as bringing the item within duty, while the later insertion of Tariff Item 27(aa) was treated as clarifying that waste and scrap were specifically covered thereafter. The question of limitation was not separately adjudicated in the final reasoning.

Conclusion: Aluminium scrap was not dutiable under Tariff Item 27(a), was dutiable under Tariff Item 68 from 1-3-1975, and was not dutiable before that date for want of a specific entry. The appeal succeeded in part with consequential relief to the assessee.

Final Conclusion: The decision settled the classification of aluminium scrap by excluding it from Tariff Item 27(a) and recognising duty liability only from the introduction of Tariff Item 68, resulting in partial relief to the assessee.

Ratio Decidendi: Scrap that is not in a metal's crude or raw form is not covered by a tariff entry limited to that crude form, and duty liability depends on the existence of a specific charging entry for the relevant period.
