Brass scrap classification and excise treatment upheld, with customs duty and additional duty applied on statutory tariff basis.

Imported brass scrap was treated as copper waste and scrap because brass is a copper-zinc alloy in which copper predominates, so the higher customs duty rate under the specific exemption notification applied. The court also upheld Tariff Item 26A(1b) covering waste and scrap as constitutionally valid, holding that commercially marketable brass scrap can be treated as excisable goods within Parliament's competence. On that basis, additional duty of customs under Section 3 of the Customs Tariff Act was also payable at the excise rate applicable to like goods produced in India, and the levy did not depend on the origin of the imported scrap.

Issues: (i) Whether brass scrap imported by the petitioners was liable to customs duty at 40% or 80% under the relevant exemption notifications. (ii) Whether insertion of Tariff Item 26A(1b) relating to waste and scrap in the Central Excises and Salt Act, 1944 by the Finance Act, 1981 was ultra vires and unconstitutional. (iii) Whether additional duty of customs under Section 3 of the Customs Tariff Act, 1975 was leviable on brass scrap imports.

Issue (i): Whether brass scrap imported by the petitioners was liable to customs duty at 40% or 80% under the relevant exemption notifications.

Analysis: Brass scrap was held to fall within Heading 74.01/02 as copper waste and scrap by application of the tariff interpretation rules and the statutory treatment of alloys, since brass is a copper-zinc alloy in which copper predominates. Notification No. 97 dated 25-6-1977 applied to articles other than copper waste and scrap, whereas Notification No. 156 dated 16-7-1977 specifically covered copper waste and scrap.

Conclusion: The petitioners were liable to customs duty at 80%, and the contention for 40% failed.

Issue (ii): Whether insertion of Tariff Item 26A(1b) relating to waste and scrap in the Central Excises and Salt Act, 1944 by the Finance Act, 1981 was ultra vires and unconstitutional.

Analysis: The Court held that brass scrap is a commercially known commodity and that its emergence involves manufacture within the constitutional conception of excise. Waste and scrap fit only for recovery of metal were treated as excisable goods, and the legislative inclusion of such item was not beyond Parliament's competence under the constitutional scheme governing duties of excise.

Conclusion: The insertion of Tariff Item 26A(1b) was intra vires, constitutional, and within legislative competence.

Issue (iii): Whether additional duty of customs under Section 3 of the Customs Tariff Act, 1975 was leviable on brass scrap imports.

Analysis: Additional duty under Section 3 is equal to the excise duty for the time being leviable on like goods if produced or manufactured in India. Since brass scrap was held excisable under the amended tariff item, the corresponding additional duty became payable on import, irrespective of the particular source of the scrap or whether the imported consignment itself arose from manufacturing waste or discarded articles.

Conclusion: The levy and collection of additional duty of customs on brass scrap was valid.

Final Conclusion: The petitioners' challenges to the customs duty rate, the excise levy on waste and scrap, and the additional duty of customs all failed, and the writ petitions were dismissed with costs.

Ratio Decidendi: Where imported brass scrap falls within the tariff classification of copper waste and scrap, and the commodity is commercially marketable and statutorily treated as excisable waste and scrap fit for recovery of metal, customs exemption and corresponding additional duty must be determined by the statutory classification and not by the origin of the particular consignment.
