Integrated pump drive not classifiable as electric motor when no separate motor emerges for excise purposes.

Rotors and stators incorporated into a monobloc centrifugal pump do not become classifiable as an electric motor under Heading 85.01 unless a separately identifiable motor emerges as a distinct commercial product. Although the rotors and stators may be dutiable as motor parts at the stage before assembly, once fixed on the common shaft within the pump the driving mechanism has no independent existence and is not a separable tariff item as an electric motor. On that basis, no further duty was chargeable at the integrated stage, and the Revenue's appeal failed.

Issues: Whether the driving mechanism in a monobloc centrifugal pump, consisting of rotors and stators mounted on the same shaft as the pump, is classifiable as an electric motor under Heading No. 85.01 of the Schedule to the Central Excise Tariff Act, 1985, and whether any further duty could be levied at that stage.

Analysis: The relevant test was whether the power mechanism in the monobloc pump came into existence as an identifiable electric motor known to trade and commerce. Although rotors and stators are parts of electric motors and were manufacturable and dutiable at the stage before their use, once they were fixed on the common shaft of the pump in the monobloc arrangement, the motor as such did not emerge as a separate commercial product. The driving mechanism was not separable, had no independent existence, and could not be classified as an electric motor for tariff purposes. The Tribunal also followed the consistent view that duty could be levied on the rotors and stators as parts of motors, but not again on the integrated driving mechanism as an electric motor.

Conclusion: The driving mechanism in the monobloc pump was not classifiable as an electric motor under Heading No. 85.01, and no further duty was chargeable at that stage. The Revenue's appeal failed.

Ratio Decidendi: Where rotors and stators are incorporated into a monobloc pump so that no separately identifiable electric motor comes into existence, the integrated mechanism is not classifiable as an electric motor for central excise purposes.
