Classification of cooling and chilling units turns on subsidiary temperature control, excluding them from Heading 8419.

Oil/water cooling and chilling units were treated as accessories or adjuncts to main machinery because the technical material showed that cooling was only a subsidiary function and the units had no independent function of their own. Chapter Note 2(e) to Chapter 84 excluded such machines from Heading 8419 where any temperature change was merely incidental to mechanical operations. The classification adopted by the lower authorities was upheld, and the goods were not classifiable under Heading 8419.

Issues: Whether oil/water cooling and chilling units were correctly classified under Heading 8466 of the Central Excise Tariff Act, 1985, or were classifiable under Heading 8419.

Analysis: Chapter Note 2(e) of Chapter 84 excludes from Heading 8419 machines designed for mechanical operations where any change of temperature is only a subsidiary function. The units were found, on the technical material relied upon, to have cooling as a subsidiary function and no independent function of their own. The record also showed that the goods were used with other machines to improve their efficiency by controlling temperature, which supported their treatment as accessories or adjuncts to the main equipment rather than as independent machines for Heading 8419.

Conclusion: The classification adopted by the lower authorities was upheld and the goods were not classifiable under Heading 8419.
