Composite machine classification for rice mill conveyors and elevators follows principal function, not general-purpose headings.

Rice bucket elevators and rice conveyors specially designed for rice milling machinery, and supplied as part of a composite rice mill setup, were classifiable under Heading 8437 because Section XVI Notes 3, 4 and 5 require composite machines to be classified according to their principal function. The goods were used only for transporting and feeding grain within the rice milling process, so they formed integral components of the composite rice milling machine. HSN explanatory notes could not displace the clear tariff section notes, and the precedent on general-purpose conveyors and elevators was distinguished on facts. Duty demand, interest and penalties based on Heading 8428 were therefore unsustainable.

Issues: Whether rice bucket elevators and rice conveyors, when specially designed for rice milling machinery and supplied as part of a composite rice mill setup, were classifiable under Heading 8437 or under Heading 8428, and whether the demand, interest and penalties based on the contrary classification could survive.

Analysis: The classification was governed by Notes 3, 4 and 5 to Section XVI of the Central Excise Tariff Act, 1985, under which composite machines fitted together to perform a clearly defined function are to be classified according to the principal function. The conveyors and elevators were found to be specially designed for rice mills, used only for transportation and feeding of grain within the rice milling process, and supplied along with other rice mill machinery to the rice millers. On that basis, they formed part of a composite rice milling machine whose principal function fell under Heading 8437. The reliance on HSN explanatory notes to shift the goods to Heading 8428 was rejected because explanatory notes are only guiding material and cannot override clear tariff notes. The precedent treating general-purpose conveyors and elevators as Heading 8428 was distinguished on facts, since the goods there were not shown to be specific composite components for rice milling machinery.

Conclusion: The goods were correctly classifiable under Heading 8437 of the Central Excise Tariff Act, 1985, and the duty demand, interest and penalties based on Heading 8428 were unsustainable.

Final Conclusion: The classification dispute was resolved in favour of the assessee, and the impugned orders were set aside with consequential relief.

Ratio Decidendi: Where goods are specially designed and supplied as integral components of a composite machine performing the principal function of rice milling, they must be classified under the heading of that principal function, and HSN explanatory notes cannot override clear tariff section notes.
