Case Note & Summary
The dispute arose from the classification of Modified Vapour Absorption Chillers (MVAC) manufactured by the appellant, M/s Thermax Ltd., under the Central Excise Tariff Act, 1985. The appellant contended that their product should be classified as a heat pump under Heading 8418, which would allow them to benefit from a limited exemption from excise duty as per Notification 155/86-CE dated 1.3.1986. The Assistant Commissioner initially supported the appellant's classification, but the Commissioner of Central Excise (Appeals) later agreed with the manufacturer. However, the Customs, Excise and Service Tax Appellate Tribunal (CESTAT) reversed this decision, concluding that MVAC was not a heat pump and thus ineligible for the concessional rate of duty. The appellant's subsequent writ petition was dismissed by the Bombay High Court, leading to the present appeal. The appellant argued that MVAC is marketed as a heat pump and incorporates features that distinguish it from ordinary chillers. They emphasized that the product can provide both chilled and hot water, which should warrant its classification as a heat pump. Conversely, the Revenue contended that the primary function of MVAC is to produce chilled water, and the production of hot water is merely incidental. The court analyzed the definitions provided in the Harmonised System of Nomenclature (HSN) and concluded that MVAC does not meet the criteria for classification as a heat pump. The court applied the Principal Purpose Test, determining that the primary purpose of MVAC is to produce chilled water. The court affirmed the CESTAT's decision, classifying MVAC under Sub-heading 8418.10 as refrigerating equipment and dismissing the appeal.
