Tariff classification of halogen lamps depends on trade identity and principal use, not incidental ultraviolet emission capability.

Tariff classification of halogen lamps turned on their commercial identity, principal use, and trade understanding rather than a conditional ability to emit ultraviolet rays. Because the lamps were marketed as single projection lamps and were not regarded in trade as ultraviolet lamps, the incidental possibility of UV emission was insufficient to support classification under Tariff Heading 85.18/27(1) read with Customs Notification 46/83. They were held classifiable under Tariff Heading 85.18/27(4), and the lower appellate classification was set aside in favour of the Revenue.

Issues: Whether halogen lamps were correctly classified under Tariff Heading 85.18/27(1) read with Customs Notification 46/83, or were classifiable under Tariff Heading 85.18/27(4).

Analysis: The classification depended on the nature of the goods as understood in trade, their principal use, and the manner in which they were marketed. The mere possibility that the lamps could emit ultraviolet rays under some conditions was insufficient, particularly when the lower appellate authority had not identified the conditions for treating them as ultraviolet lamps and had itself noted that they were not regarded as such in trade. The goods were single projection lamps, indicating that visible light was the intended output.

Conclusion: The classification under Tariff Heading 85.18/27(1) was held unsustainable and the goods were held classifiable under Tariff Heading 85.18/27(4), in favour of the Revenue.

Final Conclusion: The department's appeal succeeded and the assessment position adopted by the lower appellate authority was set aside.

Ratio Decidendi: For tariff classification, the decisive factors are the common trade understanding of the goods and their principal use, not an incidental or conditional capability that is not shown to govern their commercial identity.
