Summary
Thermax added sensors, a selector switch and wiring to its vapour absorption chillers so that they could also supply hot water. It claimed they were 'heat pumps' under Heading 84.18 of the Central Excise Tariff Act, 1985, entitled to concessional duty under Notification 155/86-CE. CESTAT disagreed, and the Supreme Court dismissed Thermax's appeals. The HSN definition, which guides classification, describes a heat pump as converting drawn heat, with supplementary energy, into more intense heat. These machines produce chilled water continuously; hot water is incidental, and customers buy them, and Thermax markets them, as chillers. Applying the principal-purpose test in Chapter Note 7 to Chapter 84 as a tie-breaker within the heading, the machines fell under sub-heading 8418.10 as refrigerating equipment.
Issues
- Whether modified vapour absorption chillers capable of also producing hot water are 'heat pumps' under Heading 84.18 of the Central Excise Tariff Act, 1985, entitled to concessional duty under Notification No. 155/86-CE.
Provisions considered
- Heading 84.18 and sub-heading 8418.10, Central Excise Tariff Act, 1985The product falls under sub-heading 8418.10 as refrigerating equipment, not as a heat pump eligible for concession. (¶¶ 2, 21)
- Chapter Note 7 to Chapter 84, Central Excise Tariff Act, 1985A machine's principal purpose is treated as its sole purpose; the note can operate as a tie-breaker between commercial classifications within one heading. (¶¶ 17, 18)
- Section 35L, Central Excise Act, 1944Statutory appeal to the Supreme Court against CESTAT's classification order. (¶¶ 2, 3)
Held
- Since the Central Excise Tariff is based on the Harmonised System, a definition in the HSN is a safe and, absent contrary indication, overriding guide to classification, as held in Wood Craft and D.L. Steels. (¶¶ 6, 7, 20)
- The machines do not satisfy the HSN definition of a heat pump because their final output is chilled water, production of which never ceases during operation; hot water is merely incidental and cannot be obtained alone. (¶¶ 8, 9, 11, 12)
- In market parlance the product is a vapour absorption chiller; the appellant markets chillers and heat pumps separately, and the added components do not change its primary character. (¶¶ 10, 13)
- Applying the principal purpose test under Chapter Note 7 and Xerox India, the sole purpose of the machine is to produce chilled water; the Blue Star and Voltas decisions, which involved rival headings and did not test the HSN definition, are distinguishable. (¶¶ 14, 15, 16, 18, 19, 21)
Result
Appeals dismissed; the product classified under sub-heading 8418.10 as refrigerating equipment and CESTAT's view affirmed; parties to bear their own costs.
