HINDUSTAN ALUMINIUM CORPORATION LTD. vs STATE OF UTTAR PRADESH & ANR.

The Supreme Court upheld the High Court's decision regarding the taxation of aluminium products under the U.P. Sales Tax Act, 1948, specifically Section 3A(2). The Court ruled that aluminium ingots and billets are distinct commercial commodities from rolled products and extrusions, which are considered new commodities. The interpretation of 'metal' in the relevant notifications was clarified to refer to its primary marketable form, thus affirming the Sales Tax Officer's assessment that treated rolled products as unclassified items subject to higher tax rates.
