Computer upgrade units treated as parts, not complete machines, where they only enhanced existing systems.

Computer upgrade units fitted into existing systems and used only to enhance memory, speed, storage, printing capacity and connectivity were not complete computers under Chapter 8471. Because the other essential components remained unchanged and the units operated only as a sub-assembly or part of the existing system, classification as a complete machine was rejected. The classification under Chapter 8473 as a part or sub-assembly was upheld, and the challenge failed.

Issues: Whether computer upgrade units used in existing computer systems were classifiable as a complete machine under Chapter 8471 or as a part or sub-assembly under Chapter 8473 of the Central Excise Tariff Act, 1985.

Analysis: The units were used only to upgrade existing computer systems by enhancing memory, speed, storage, printing capacity and connectivity. The record showed that the upgrades were fitted into an existing system and did not themselves constitute a complete computer or complete machine. The other essential components of the computer remained unchanged, and the upgrade units functioned only as a sub-assembly or part of the existing system. On that basis, the claimed classification as a complete machine under Chapter 8471 was rejected.

Conclusion: The upgrade units were correctly treated as a sub-assembly and not as a complete machine; the classification adopted in the impugned order was upheld and the assessee's challenge failed.
