Refrigeration-based industrial cooling units fall under Heading 84.18, not air conditioning classification, under the applicable tariff circular.

Industrial cooling units operating on refrigeration principles are classifiable under Heading 84.18 as refrigerating appliances and machinery, not under Heading 84.15 as air conditioning machines, where their technical characteristics and the applicable Board circular support that view. The circular states that freezers and freezing equipment function on refrigeration, are essentially refrigerators maintained at sub-zero temperatures, and fall within Heading 84.18. On that basis, a contrary classification under Heading 84.15 is not sustainable, and the tariff classification governs entitlement to the related exemption notification.

Issues: Whether the imported industrial cooling unit was classifiable under Heading 84.18 as refrigerating equipment or under Heading 84.15 as an air conditioning machine, and whether it was entitled to the benefit of the relevant exemption notification.

Analysis: The dispute turned on the technical characteristics of the imported unit and the proper application of the tariff headings. The Board's circular clarified that freezers and freezing equipment operate on the mechanism of refrigeration, are essentially refrigerators maintained at sub-zero temperatures, and fall within Heading 84.18 of the Central Excise Tariff Act, 1985. It further noted that such goods are covered by the description of other refrigerating appliances and machinery, and that the revenue cannot contend contrary to the Board's clarification. In view of that circular, the classification adopted by the lower authority under Heading 84.15 was not sustainable.

Conclusion: The goods were held classifiable under Heading 84.18 as refrigerating appliances and machinery, not under Heading 84.15 as air conditioning machines, and the appeal was allowed with consequential relief.
