Heat exchanger classification upheld for modular thermal storage equipment; air-conditioning heading rejected on catalogue and HSN interpretation.

Imported goods described in the product literature as a modular tube-in-tank ice thermal storage system were treated as a heat exchanger under Heading 8419.50, because the catalogue also described them as a super efficient heat exchanger and the HSN-based interpretation, rival contentions, and Board instructions supported that classification. The challenge that the catalogue did not describe the product as a heat exchanger was rejected as incorrect, and no material was produced to disturb the classification already accepted by the lower authorities. Classification as an air-conditioning machine under Heading 8415.83 was therefore not accepted.

Issues: Whether the imported product was classifiable as a heat exchanger under Heading 8419.50 or as an air-conditioning machine under Heading 8415.83.

Analysis: The product literature described the goods as a modular tube-in-tank ice thermal storage system and also referred to it as a super efficient heat exchanger yielding top performance. The classification adopted by the lower authorities under Heading 8419.50 was supported by the catalogue, the Board's instructions, the rival contentions, and the HSN-based interpretation applied below. The claim in the appeal that the catalogue did not describe the product as a heat exchanger was found to be incorrect, and no material was shown to dislodge the classification already accepted by the lower authorities.

Conclusion: The product was held to be classifiable as a heat exchanger under Heading 8419.50, and the Revenue's contention for classification under Heading 8415.83 was rejected.
