Electronic microassemblies classification under Heading 8542 prevails over functional heading 8531 for imported LED display modules.

LED displays imported as 7 segment, 16 segment and dot matrix units were held to be electronic microassemblies under Heading 8542, because the technical material described them as discrete active devices assembled with interconnecting conductors and enclosed in moulded plastic casings, forming inseparable modules. Chapter 85 Note 5 gave Headings 8541 and 8542 precedence over competing headings based on function, so the goods could not be treated as parts of electric sound or visual signalling apparatus under Heading 8531. The classification under Heading 8542 was sustained and the revenue challenge failed.

Issues: Whether LED displays imported as 7 segment, 16 segment and dot matrix units were classifiable under Heading 8542 as electronic microassemblies or under Heading 8531 as parts of electric sound or visual signalling apparatus.

Analysis: The technical material on record described the items as discrete active devices assembled with interconnecting conductors and enclosed in moulded plastic casings, making them inseparable modules. The classification notes for Chapter 85 treated electronic microassemblies as covered by Heading 8542, and Note 5 of Chapter 85 provided that Headings 8541 and 8542 take precedence over any other heading that may otherwise cover the goods by reference to function. On that basis, the goods could not be classified as parts of bells, sirens, indicator panels or similar signalling apparatus under Heading 8531.

Conclusion: The goods were correctly classified under Heading 8542 as electronic microassemblies, and not under Heading 8531.

Final Conclusion: The revenue challenge to the classification failed, and the assessee's classification was sustained.

Ratio Decidendi: Where goods answer the description of electronic microassemblies under Heading 8542, that heading prevails over a competing functional heading by virtue of the chapter note giving precedence to the specific technical classification.
