Tariff classification of aluminium grills and dampers depends on true commercial use, not mere possible use in air-conditioning systems.

Aluminium grills, diffusers and dampers used mainly in ventilation systems, false ceilings, walls and building installations were treated as general-purpose aluminium articles rather than integral or inseparable parts of air-conditioning machines. The classification turned on their true commercial character and actual use, and the factual material, including the prior trade notice and excise findings, supported Chapter 76 instead of Tariff Entry 84.15. A circular directing classification under Tariff Entry 84.15 was considered unsustainable because it ignored the established factual position that the goods were not supplied for use as air-conditioning machine parts. The alternative-remedy objection was not accepted where only a question of law remained.

Issues: Whether aluminium grills, diffusers and dampers manufactured by the petitioner were classifiable under Tariff Entry 84.15 as parts of air-conditioning machines or under Chapter 76 as aluminium articles, and whether the impugned circular directing classification under Tariff Entry 84.15 was sustainable.

Analysis: The products were found to be general-purpose aluminium grills, diffusers and dampers used mainly in ventilation systems, false ceilings, walls and building installations, and not as integral or inseparable parts of air-conditioning machines. The factual enquiry conducted by the Central Excise authorities, the earlier trade notice, and the reasoning adopted by the CEGAT supported classification under Chapter 76. The impugned circular ignored the factual position that the goods were not supplied for use in air-conditioning machines. The objection based on alternative remedy was rejected because the dispute had already been examined in detail and only a question of law remained. The Court also accepted the view that the prior decision on classification supported the petitioner's stand.

Conclusion: The goods were not classifiable under Tariff Entry 84.15 and were liable to be classified under Chapter 76 as articles of aluminium.

Final Conclusion: The writ petition succeeded and the circular directing classification under Tariff Entry 84.15 could not stand in view of the proper tariff classification of the goods.

Ratio Decidendi: Goods used for ventilation or building installations, which are not integral and inseparable parts of an air-conditioning machine, are not classifiable as parts of such machine merely because they may be used in air-conditioning systems; their classification depends on their true commercial character and use.
