Functional classification of photo tubes sustained, with exemption preserved because they were sensing components, not display devices.

Photo tubes used as light-sensitive components in a spectrophotometer were classified under Heading 85.18/27 because they formed part of the electronic device and the classification objection was not pursued in a contrary manner. The exemption under Notification No. 172/77-Cus. remained available because the exclusion for electronic valves and tubes used as display devices did not apply: the photo tubes only converted light into electrical signals, while the panel meter performed the display function. On that functional basis, the department's challenge to the refund and concessional duty benefit failed, and the assessee retained the exemption.

Issues: (i) Whether the imported photo tubes were correctly classifiable under Heading 85.18/27 of the Customs Tariff Act, 1975. (ii) Whether the photo tubes were excluded from the benefit of Notification No. 172/77-Cus. dated 8-8-1977 as electronic valves and tubes used as display devices.

Issue (i): Whether the imported photo tubes were correctly classifiable under Heading 85.18/27 of the Customs Tariff Act, 1975.

Analysis: The classification dispute was not pressed in the same manner before the Tribunal, and the goods were accepted as electronic devices and component parts of a spectrophotometer. On that basis, the correct tariff placement was under Heading 85.18/27.

Conclusion: The goods were held classifiable under Heading 85.18/27.

Issue (ii): Whether the photo tubes were excluded from the benefit of Notification No. 172/77-Cus. dated 8-8-1977 as electronic valves and tubes used as display devices.

Analysis: The notification granted concessional duty to goods under Heading 85.18/27, but carved out specified electronic valves and tubes, including cold cathode and thermionic types used as display devices. The Tribunal accepted that the photo tubes functioned as light-sensitive components in a spectrophotometer, converting light energy into electrical signals for further amplification, while the panel meter was the actual display device. As the photo tubes were not themselves display devices, they did not fall within the exclusionary entry.

Conclusion: The photo tubes were held to be eligible for the notification benefit and not covered by the exclusion.

Final Conclusion: The department's challenge to the refund and concessional duty benefit failed, and the assessee retained the benefit of the exemption notification.

Ratio Decidendi: Goods that perform only a sensing or signal-conversion function in an instrument are not "display devices" merely because the instrument ultimately displays the result through another component; an exemption notification exclusion must be applied according to the actual function of the goods.
