Functional classification of air-conditioning grills and diffusers upheld as machine parts, not general aluminium articles.

Aluminium grills and diffusers made for centralised air-conditioning systems were classified as parts of air-conditioning machinery under Heading 84.15, because their principal function was to guide, distribute and control airflow and they were commercially understood as system components. Classification under Heading 7616.90 as general aluminium articles was rejected since the goods were not mere decorative or general-purpose items. Applying the scheme of Section XVI and the relevant interpretative notes, the contrary duty demand, penalty and interest based on the wrong classification were set aside.

Issues: Whether aluminium grills and diffusers manufactured for use in centralised air-conditioning systems were classifiable under Heading 84.15 as parts of air-conditioning systems or under Heading 7616.90 as aluminium articles, and whether the demand, penalty and interest based on the contrary classification could stand.

Analysis: The decisive test was the functional and principal use of the goods. The goods were designed to guide, distribute and control airflow in air-conditioning duct systems and were commercially understood as parts of air-conditioning systems. On that reasoning, they were held to be suitable for use solely or principally with air-conditioning machinery and therefore to fall under Heading 84.15 under the scheme of Section XVI and the relevant interpretative notes. The view that they were mere articles of general use under Chapter 76 was rejected because the goods were not being treated as general-purpose decorative items but as identifiable functional parts of a specific machine/system. The departmental circular supporting classification under Heading 84.15 for grills used with air-conditioning systems was applied, while the assessee's reliance on general-purpose grill treatment was found inapposite on the facts. Once the classification under Heading 84.15 was accepted, the resulting duty demand, penalty and interest were liable to be set aside.

Conclusion: The goods were held classifiable as parts of air-conditioning systems under Heading 84.15, not under Heading 7616.90, and the assessee succeeded in getting the demand and penalty set aside.
