Tariff classification of condensers favours Heading 84.18 where goods function as liquifiers, not temperature-treatment machinery.

Condensers and cooling coils were treated as classifiable under Heading 84.18 rather than Heading 84.19 of the Central Excise Tariff Act, because Heading 84.19 applies only to machinery, plant or laboratory equipment used for treatment of materials by a process involving a change of temperature. The goods in question did not meet that requirement, and the lower appellate view lacked supporting reasons or evidence of exclusive use in air-conditioners. HSN Explanatory Notes also supported classification of condensers functioning as liquifiers, where gas is cooled and liquified, under Heading 84.18.

Issues: Whether condensers and cooling coils manufactured by the respondents were classifiable under Heading 84.18 of the Schedule to the Central Excise Tariff Act, 1985, or under Heading 84.19.

Analysis: Heading 84.19 applies only to machinery, plant or laboratory equipment used for the treatment of materials by a process involving a change of temperature. The condensers and cooling coils in question did not satisfy that requirement. The classification adopted by the lower appellate authority was unsupported by reasons or evidence as to exclusive use in air-conditioners. The HSN Explanatory Notes also indicated that condensers functioning as liquifiers, where gas is cooled and liquified, fall under Heading 84.18.

Conclusion: The products were classifiable under Heading 84.18 and not under Heading 84.19, in favour of the Revenue.

Ratio Decidendi: Where a tariff entry is specific to condensers functioning as liquifiers, and the competing entry applies only to equipment used for treatment of materials by a process involving change of temperature, the goods fall under the specific condenser heading.
