Tariff classification of switch mode power supply remanded for fresh scrutiny where technical features remained unresolved.

Tariff classification of an imported switch mode power supply depended on unresolved technical features and the relevant Chapter 84 note. The record suggested the item may do more than supply power and may transmit signals to the computer, but the evidence was not sufficient for a conclusive classification under heading 84.71 or as equipment covered by Note 5(B) of Chapter 84. Because the Commissioner (Appeals) had reached a brief conclusion without fuller technical scrutiny, the matter was remanded to the original authority for de novo adjudication after both sides were allowed to place material and rebut contentions.

Issues: Whether the classification dispute concerning the imported Switch Mode Power Supply required fresh examination on the basis of technical literature and the relevant Chapter Note, warranting remand to the original authority.

Analysis: The dispute turned on whether the imported item was a mere power supply unit falling under heading 84.71 or a Switch Mode Power Supply specifically designed for and used exclusively in computers so as to satisfy Note 5(B) of Chapter 84. The technical literature produced by the importer indicated that the item may do more than supply power and may transmit signals to the computer, but the record was not sufficient for a conclusive classification. Since the Commissioner (Appeals) had reached the conclusion in a brief manner and the technical aspects required fuller scrutiny, the matter needed fresh consideration by the original authority after giving both sides an opportunity to place material and rebut contentions.

Conclusion: The classification issue was remanded to the original authority for de novo adjudication.

Ratio Decidendi: Where tariff classification depends on unresolved technical features and the existing record is insufficient for a conclusive determination, the matter may be remanded for fresh adjudication on evidence.
