Tariff classification by own identity prevailed, with only the Band Pass Filter and Floor Stand accepted as parts of the apparatus.

Tariff classification under Heading 90.29 turned on whether each item retained its own tariff identity or qualified as a part or accessory of the Sine Generator. The Band Pass Filter was classifiable under Heading 90.29(1) because it lacked the electronic devices required for sub-heading (2). The Microphone Cartridge, Cables, Recording Paper, Inking Kit and Pens were not treated as essential parts, as Chapter Note 2 required goods answerable in their own headings to be classified accordingly; their existing classifications were upheld. The Floor Stand was accepted as an essential mounting base for the apparatus and classified under Heading 90.29(1).

Issues: (i) Whether the Band Pass Filter was classifiable under Heading 90.29(1) of the Customs Tariff Act, 1975 instead of Heading 90.29(2); (ii) Whether the Microphone Cartridge and Cables were classifiable as essential parts of the Sine Generator under Heading 90.29(1) of the Customs Tariff Act, 1975; (iii) Whether the Recording Paper, Inking Kit and Pens were classifiable under Heading 90.29(1) of the Customs Tariff Act, 1975 as essential items for the Sine Generator; (iv) Whether the Floor Stand was classifiable under Heading 90.29(1) of the Customs Tariff Act, 1975 instead of Heading 73.33/40.

Issue (i): Whether the Band Pass Filter was classifiable under Heading 90.29(1) of the Customs Tariff Act, 1975 instead of Heading 90.29(2).

Analysis: The Band Pass Filter did not contain the devices required for coverage under sub-heading (2). On the tariff scheme applied, sub-heading (2) covered only parts and accessories containing the specified electronic components. In the absence of those components, the item fell within sub-heading (1).

Conclusion: The classification claim of the assessee was allowed and the item was held classifiable under Heading 90.29(1).

Issue (ii): Whether the Microphone Cartridge and Cables were classifiable as essential parts of the Sine Generator under Heading 90.29(1) of the Customs Tariff Act, 1975.

Analysis: Although the items were said to be necessary for working of the Sine Generator, Chapter Note 2 of Chapter 90 required classification of parts or accessories in the heading appropriate to their own description when they constituted goods of the relevant kind. These items were separately classifiable in their respective headings on merits.

Conclusion: The assessee's claim was rejected and the existing classification was upheld.

Issue (iii): Whether the Recording Paper, Inking Kit and Pens were classifiable under Heading 90.29(1) of the Customs Tariff Act, 1975 as essential items for the Sine Generator.

Analysis: The goods were claimed to be necessary for use with the Sine Generator, but the applicable chapter note required them to be classified in their respective headings rather than treated as parts of the instrument. Their utility with the machine did not displace their own tariff identity.

Conclusion: The assessee's claim was rejected and the customs assessment was confirmed.

Issue (iv): Whether the Floor Stand was classifiable under Heading 90.29(1) of the Customs Tariff Act, 1975 instead of Heading 73.33/40.

Analysis: The Floor Stand was treated as more than a mere article of iron and steel because it served as the mounting base for the Sine Generator and was regarded as an essential part of the apparatus. On that basis, it was brought within the claimed heading.

Conclusion: The assessee's claim was allowed and the item was classified under Heading 90.29(1).

Final Conclusion: The appeal succeeded only in respect of the Band Pass Filter and the Floor Stand, while the remaining items retained their existing classifications.

Ratio Decidendi: Where the tariff and chapter notes require an article to be classified according to its own tariff identity, its functional use with another machine does not by itself justify classification as that machine's part or accessory.
