Essential character test governs composite goods classification; differential duty cannot be recovered after approved classification lists.

Composite goods are classified under the component that gives them their essential character under Rule 3(b), not by weight or value alone. Flanged bobbins, consisting of a hollow aluminium tube with plastic around it, were treated as articles of aluminium because the tube gave the product its principal wrapping and unwinding function, so classification under sub-heading 7616.90 was upheld. Where clearances were made on the basis of classification lists approved by the department, later recovery of differential duty was held unsustainable, because such clearances do not amount to a short levy merely due to a subsequent change in view.

Issues: (i) whether flanged bobbins were classifiable as articles of aluminium under sub-heading 7616.90 or as articles of plastic under sub-heading 3926.90; and (ii) whether the demand for differential duty was sustainable when the goods had been cleared under approved classification lists.

Issue (i): whether flanged bobbins were classifiable as articles of aluminium under sub-heading 7616.90 or as articles of plastic under sub-heading 3926.90

Analysis: Composite goods are to be classified under the material or component that gives them their essential character under Rule 3(b) of the Rules for Interpretation of the Schedule to the Central Excise Tariff Act. The essential character is not determined merely by the weight or value of the components. The flanged bobbins were found to consist of a hollow aluminium tube with plastic around it, and the tube was treated as imparting the essential character because yarn was wrapped around it and the auxiliary parts served the wrapping and unwinding function.

Conclusion: The product was classifiable under sub-heading 7616.90 as articles of aluminium, against the assessee.

Issue (ii): whether the demand for differential duty was sustainable when the goods had been cleared under approved classification lists

Analysis: The clearance was made on the basis of classification lists approved by the department. In such a situation, levy on the basis of the approved classification list does not amount to a short levy, and differential duty cannot be recovered merely by later seeking modification of the classification.

Conclusion: The demand for differential duty was unsustainable, in favour of the assessee.

Final Conclusion: The classification was upheld in favour of revenue, but the duty demand was set aside because the clearances were made under approved classification lists, resulting in partial relief to the assessee.

Ratio Decidendi: For composite goods, classification depends on the component giving the goods their essential character, and differential duty cannot be recovered where clearance was made under an approved classification list.
