Tariff classification of bearing components turns on essential function; textile machinery use does not alter plain bearing classification.

Foot step bearings were held classifiable as plain shaft bearings under Heading 84.63 because their essential function was to support and position rotating shafts, and their use in textile machinery did not change that character. Roller retainers or metal cages were treated as parts of anti-friction bearings under Heading 84.62 on the basis that cages form an integral component of such bearings. As Heading 84.62 was not covered by Notification No. 35/79-Cus. at the relevant time, exemption was unavailable. The classification adopted by the department was upheld and the exemption claim failed.

Issues: (i) Whether foot step bearings were classifiable under Heading 84.63 of the Customs Tariff Act, 1975 as bearings or under Heading 84.38(1) as parts and accessories of textile machinery; (ii) Whether roller retainers or metal cages were classifiable under Heading 84.62 and, if so, whether they were entitled to exemption under Notification No. 35/79-Cus. dated 15-12-1979.

Issue (i): Whether foot step bearings were classifiable under Heading 84.63 of the Customs Tariff Act, 1975 as bearings or under Heading 84.38(1) as parts and accessories of textile machinery.

Analysis: The tariff scheme distinguished plain shaft bearings under Heading 84.63 from textile machinery parts under Heading 84.38. The technical material showed that a plain bearing supports rotating shafts, guides moving parts, and may position shafts. The goods described as foot step bearings performed that supporting and positioning function. Their use in textile machinery did not change their essential character, and their form in one or more pieces did not matter where they constituted a bearing. Heading 84.63 also covered plain shaft bearings with or without housings.

Conclusion: Foot step bearings were correctly classifiable under Heading 84.63 as bearings, and not under Heading 84.38(1).

Issue (ii): Whether roller retainers or metal cages were classifiable under Heading 84.62 and, if so, whether they were entitled to exemption under Notification No. 35/79-Cus. dated 15-12-1979.

Analysis: The material on record and the technical literature showed that anti-friction bearings comprise races, rolling elements, and cages, and that cages are parts of ball, roller or needle roller bearings. On that basis, roller retainers or metal cages fell under Heading 84.62. Since Heading 84.62 was not covered by Notification No. 35/79-Cus. as applicable at the relevant time, the exemption was unavailable.

Conclusion: Roller retainers or metal cages were classifiable under Heading 84.62 and were not eligible for exemption under Notification No. 35/79-Cus.

Final Conclusion: The classification adopted by the department was upheld, the exemption claim failed, and the assessee's appeals were rejected while the department's appeal succeeded.

Ratio Decidendi: The essential function and commercial character of a goods determine tariff classification, and a component that forms an integral part of a bearing remains classifiable as a bearing part even if it is used in textile machinery; exemption notifications must be confined to the headings they expressly cover.
