Machine-part classification under tariff headings turns on clear coverage by the rival entry, not functional similarity alone.

Classification of machine parts under Section Note 2 of Section XVI depends on whether the goods are clearly covered by a rival specific heading. Shafts manufactured for weaving machines were not shown to be transmission shafts under Heading 84.83 and were therefore classifiable as essential parts of weaving machines under Heading 84.48. Bushes for weaving machines were also not covered by Heading 84.83, since bushes are commercially distinct from bearings and cannot be treated as bearings merely on functional similarity; they were accordingly classifiable under Heading 84.48 as parts and accessories suitable for use solely or principally with weaving machines. The Revenue's challenge to the classification failed.

Issues: (i) Whether shafts manufactured for weaving machines were classifiable under Heading 84.48 as parts of weaving machines or under Heading 84.83 as transmission shafts; (ii) Whether bushes manufactured for weaving machines were classifiable under Heading 84.48 or could be brought under Heading 84.83 as bearings or analogous goods.

Issue (i): Whether shafts manufactured for weaving machines were classifiable under Heading 84.48 as parts of weaving machines or under Heading 84.83 as transmission shafts.

Analysis: Section Note 2 of Section XVI required classification of machine parts in the sequential manner set out in clauses (a), (b) and (c). Although Heading 84.83 and Heading 84.48 were both specific entries, Heading 84.83 would prevail only if the goods in question were covered by that heading. The shafts were not shown to be transmission shafts within Heading 84.83, and the finding that they were essential parts of weaving machines remained unrebutted.

Conclusion: The shafts were correctly classifiable under Heading 84.48 and not under Heading 84.83, in favour of the assessee.

Issue (ii): Whether bushes manufactured for weaving machines were classifiable under Heading 84.48 or could be brought under Heading 84.83 as bearings or analogous goods.

Analysis: Bushes were not mentioned in Heading 84.83 at all. Treating them as bearings merely on the basis of functional similarity was held to be untenable because bushes and bearings are commercially distinct goods. Since they were parts and accessories suitable for use solely or principally with weaving machines, they fell within Heading 84.48.

Conclusion: The bushes were correctly classifiable under Heading 84.48 and not under Heading 84.83, in favour of the assessee.

Final Conclusion: The Revenue's challenge to the classification failed, and the assessee retained the lower appellate relief on classification and duty demand.

Ratio Decidendi: For classification of machine parts, a specific tariff entry applies only when the goods are clearly covered by that entry; where the goods are not shown to fall within the rival specific heading, they are to be classified as parts suitable for use solely or principally with the relevant machine.
