ITW SIGNODE INDIA LTD. vs COLLECTOR OF CENTRAL EXCISE

The Supreme Court addressed the issue of classification of goods under the Central Excise Tariff Act, 1985, specifically regarding the classification of box strappings made from duty-paid cold rolled steel strips. The Court held that the Assistant Collector's earlier decision, which classified the product under Tariff Item 26AA(iii) and deemed no further excise duty applicable, was final and binding, thus preventing the Collector from raising a demand under Section 11A of the Central Excise Act. The judgment reinforced the principle that a validating statute cannot alter the classification of goods retrospectively once a decision has become final.
