Torsion shaft classification under the tariff: a transmission shaft specific heading prevailed over the residual machinery entry.

A torsion shaft that transmits rotary motive power through a gear box arrangement falls within the description of a transmission shaft. Section Note 2 of Section XVI of the Central Excise Tariff, 1985 requires parts that are specifically covered by a heading in Chapters 84 or 85 to be classified under that heading rather than under a residual entry. As transmission shafts are expressly covered by sub-heading 8483.00, the general residual heading 8479.00 for machinery and mechanical appliances with individual functions could not apply. The torsion shaft was therefore correctly classifiable under sub-heading 8483.00 and not under sub-heading 8479.00.

Issues: Whether the product "Torsion Shaft" was classifiable under sub-heading 8479.00 as machinery and mechanical appliances having individual functions not specified elsewhere, or under sub-heading 8483.00 as a transmission shaft.

Analysis: The product, on the facts and diagram placed on record, was found to transmit rotary motive power through the gear box arrangement and therefore answered the description of a transmission shaft. The classification dispute was governed by Section Note 2 of Section XVI of the Central Excise Tariff, 1985, which requires parts included in a heading of Chapter 84 or 85 to be classified in their respective headings. Since transmission shafts are specifically covered by sub-heading 8483.00, the more general residual heading 8479.00 could not apply.

Conclusion: The Torsion Shaft was correctly classifiable under sub-heading 8483.00 and not under sub-heading 8479.00, against the assessee.
