Refrigerating machinery classification prevails for vapour absorption units despite air-conditioning use and dual output capability.

A vapour absorption unit was treated as classifiable under Chapter Heading 8418 as refrigerating machinery rather than under Chapter Heading 8415 as air-conditioning equipment. Classification depended on the nature of the machine as cleared, supported by product literature and technical features showing a complete absorption-type heat pump capable of producing chilled water and hot water. The outlet water temperature was held not decisive; for refrigerating machinery, the relevant factor was the temperature of the active cooling element. Earlier rulings on chillers and similar equipment were followed, confirming that use in air-conditioning did not alter classification under Chapter Heading 8418.

Issues: Whether vapour absorption unit (VAM) was classifiable under Chapter Heading 8418 as refrigerating machinery or under Chapter Heading 8415 as air-conditioning equipment, and consequently whether the Revenue's appeal against the classification order could succeed.

Analysis: The product literature and technical features showed that the unit was a complete absorption-type heat pump capable of producing chilled water as well as hot water, and that classification had to be determined from the nature of the machine as cleared, not from possible additional attachments or uses. The temperature of the output water was held not to be ative; for refrigerating machinery, the relevant consideration was the temperature of the active cooling element, not merely the outlet temperature. The Tribunal followed earlier decisions holding that a chiller or similar equipment remained classifiable under Chapter Heading 8418 as refrigerating equipment even if it could also be used in air-conditioning applications.

Conclusion: The VAM was correctly classifiable under Chapter Heading 8418 of the Central Excise Tariff Act, 1985. The Revenue's contention under Chapter Heading 8415 failed.
