Composite goods classification turns on essential character, and a turbo gear unit was held classifiable as a steam turbine.

Composite goods are classified by their essential character under Rule 3(b) of the Rules for the Interpretation of the Schedule to the Central Excise Tariff Act, 1985. A Turbo Gear Unit comprising a turbine and gear box was treated as a steam turbine under Heading 8406 because the turbine generated power and the gear box only transmitted that power. The HSN Explanatory Notes to Heading 84.06 support classification of turbines fitted with reduction or reversing gears within that heading, while separate gears fall under Heading 84.83. As the unit's main and effective function was power generation, the gear box attachment did not alter classification, and the contrary classification under Heading 8483 was rejected.

Issues: Whether a Turbo Gear Unit, consisting of a turbine and gear box, was classifiable under Heading 8406 as a steam turbine or under Heading 8483 as gear boxes and other speed changers.

Analysis: The dispute turned on the classification of composite goods. The turbine element generated power and the gear box merely transmitted that power. In such a case, classification had to be determined by the essential character of the goods under Rule 3(b) of the Rules for the Interpretation of the Schedule to the Central Excise Tariff Act, 1985. The HSN Explanatory Notes to Heading 84.06 also indicated that turbines fitted with reversing or reduction gears remain within Heading 84.06, and that only such gears presented separately fall under Heading 84.83. Since the main and only effective function of the product was power generation, the attachment of the gear box did not alter its classification.

Conclusion: The Turbo Gear Unit was classifiable under Heading 8406 and not under Heading 8483.

Final Conclusion: The order classifying the product under Heading 8483 was set aside and the assessee's classification claim was accepted.
