Binding tariff classification clarification under Section 37B governs tape deck mechanism classification under sub-heading 8548.00.

Tape deck mechanism used in cassette tape recorders and similar equipment was treated, having regard to Section XVI Note 2 and the product's interchangeable use, as a general purpose part classifiable under sub-heading 8548.00 rather than heading 85.22. A specific classification clarification issued by the Central Board of Excise and Customs under Section 37B was binding on the departmental authorities, who could not depart from it and press a contrary classification. The result was that the classification adopted below was unsustainable and the impugned order was set aside.

Issues: (i) Whether tape deck mechanism was classifiable under sub-heading 8548.00 or under heading 85.22; (ii) whether the departmental authorities were bound by the Board's order issued under Section 37B.

Issue (i): Whether tape deck mechanism was classifiable under sub-heading 8548.00 or under heading 85.22

Analysis: The product was examined in the light of the Board's clarification, which noted that tape deck mechanism is used in cassette tape recorders, radio cassette recorders, telephone answering machines and similar equipment. Having regard to Note 2 of Section XVI of the Customs Tariff Act, 1975, the composition of the product and its interchangeable use, the Board treated it as a general purpose part falling under sub-heading 8548.00.

Conclusion: The goods were held classifiable under sub-heading 8548.00 and not under heading 85.22.

Issue (ii): Whether the departmental authorities were bound by the Board's order issued under Section 37B

Analysis: Once the Central Board of Excise and Customs had issued a specific order under Section 37B clarifying the classification, the revenue could not depart from that position and contend for classification under heading 85.22.

Conclusion: The departmental authorities were bound by the Board's order and could not resile from it.

Final Conclusion: The classification adopted by the authorities below was unsustainable, and the appeals succeeded with the impugned order being set aside.

Ratio Decidendi: A classification clarification issued by the competent Board under Section 37B is binding on the department, and tariff classification must follow the applicable chapter notes and the Board's binding interpretation.
