Principal function governs tariff classification of rice mill conveyors and elevators, defeating the general heading and related demand.

Rice bucket elevators and rice conveyors specially designed for use with rice milling machinery were classified under heading 8437 as machinery used in the milling industry, not under heading 8428 as general lifting, handling or loading equipment. Applying Section Notes 3, 4 and 5 to Section XVI of the Central Excise Tariff Act, 1985, the principal function of the composite rice-milling setup governed classification, and the HSN explanatory notes could not override the clear tariff notes. On that basis, the duty demand, interest and penalty founded on heading 8428 were held unsustainable, and the impugned classification order was set aside.

Issues: Whether rice bucket elevators and rice conveyors specially designed for rice mills were classifiable under heading 8437 as machinery used in milling industry or under heading 8428 as lifting, handling, loading or unloading machinery, and whether the resulting demand, interest and penalty could survive.

Analysis: The goods were found to be specifically manufactured for use along with rice milling machinery and supplied as part of a composite rice-milling setup. Applying Section Notes 3, 4 and 5 to Section XVI of the Central Excise Tariff Act, 1985, the relevant classification follows the principal function of the combined machinery. The heading for machinery used in milling industry was held to be the appropriate heading, and the HSN explanatory notes could not override the clear tariff notes. The elevators and conveyors, being specially designed for rice milling and functioning as grain-feeding components of the milling line, were held to fall under heading 8437 rather than the general heading 8428.

Conclusion: The rice bucket elevators and rice conveyors were correctly classifiable under heading 8437 of the Central Excise Tariff Act, 1985, and the demand, interest and penalty based on classification under heading 8428 were not sustainable.

Final Conclusion: The impugned classification order was set aside and the assessee obtained full relief against the duty demand and consequential penal action.

Ratio Decidendi: Where machinery is specially designed as part of a composite setup for a specific milling industry function, classification must be determined by the principal function under the tariff notes, and general explanatory notes cannot displace the clear statutory scheme.
