Integrated circuit classification denied as discrete transistor or diode goods, defeating the claimed exemption under tariff law.

Integrated circuits were treated as distinct composite circuit products built on a silicon chip, not as discrete transistors or semiconductor diodes. Because the tariff description covered only discrete components, the goods could not be reclassified under that heading despite containing transistor and diode elements. The notification-based exemption therefore did not apply, and the assessee's classification claim failed. The governing principle was that a monolithic integrated circuit remains a complete circuit system and cannot be equated with individual semiconductor devices for tariff or exemption purposes.

Issues: Whether integrated circuits imported by the appellants were classifiable as transistors and semiconductor diodes for excise purposes and, on that basis, entitled to exemption under the cited notification.

Analysis: The integrated circuit was found to be a complete circuit system built on a silicon chip, comprising interconnected components fabricated by semiconductor processes. Although it contained transistors and diodes, it was not treated as the same thing as discrete transistors or semiconductor diodes. The relevant tariff description was held to cover only discrete components, not a monolithic circuit assembled on a chip. The notification-based exemption therefore did not apply to the goods as claimed.

Conclusion: The classification claim failed and the exemption was denied; the decision was against the assessee.

Final Conclusion: Integrated circuits were held to be a distinct composite circuit product and not merely transistors or semiconductor diodes, so the appeal failed.

Ratio Decidendi: A monolithic integrated circuit, though composed of transistor and diode elements, is a distinct complete circuit product and cannot be classified as discrete transistors or semiconductor diodes for tariff or exemption purposes.
