Aluminium grills, diffusers and dampers treated as general-use items, not integral air-conditioning parts, for tax classification.

Aluminium grills, diffusers and dampers used for ventilation were treated as goods capable of general use in houses and industrial premises, not as integral parts or accessories of air conditioning or refrigeration plant. The Court noted that limited use in air-conditioning systems did not by itself change the character of the items, and that some sales to air-conditioning manufacturers were insufficient to justify higher-rate taxation. The result was that these items were held not taxable at the higher rate applicable to air-conditioning plant and were treated in favour of the assessee.

Issues: Whether aluminium grills, diffusers and dampers are to be treated as integral parts or accessories of air conditioning or refrigeration plant and taxed at the higher rate, or as unclassified items taxable at the lower rate.

Analysis: The items in question were found to be capable of general use in houses, industrial premises and other places for ventilation and related purposes, and not confined to air conditioning equipment alone. The Court relied on its earlier view that such goods may be used for covering openings of air conditioning systems, but that does not make them an integral part of the system. The Tribunal's emphasis on some sales to air conditioning manufacturers was held insufficient to change the character of the goods, especially when previous assessments had treated them differently.

Conclusion: Aluminium grills, diffusers and dampers are not integral parts of air conditioning or air cooling plant and cannot be taxed at the rate of 15%; the issue is decided in favour of the assessee.
