Monoblock pump components were not separately identifiable as electric motors, so duty under the motor tariff classification failed.

Duty could not be demanded on rotors and stators used in monoblock pumps on the footing that they were separately identifiable electric motors or a distinct driving mechanism. The Tribunal found that the electric motor did not emerge in an identifiable or separable form within the monoblock pump, and that the casing and shaft were common to both the pump and the rotors and stators. Relying on departmental clarification, trade notice, and prior Tribunal rulings, it held that classification under Tariff Item 30 was not warranted where the components were not separately identifiable as electric motors in the assembled pump.

Issues: Whether duty could be demanded on rotors and stators used in the manufacture of monoblock pumps on the footing that they constituted identifiable electric motors or their driving mechanism.

Analysis: The impugned order proceeded on the finding that in monoblock pumps the electric motor does not come into existence in an identifiable and separable form, and that the casing and shaft are common to both the pump and the rotors and stators. The earlier departmental clarification and trade notice were relied upon to support the view that classification under Tariff Item 30 was not warranted. The decision also followed prior Tribunal rulings holding that rotors and stators used in such driving mechanism may be liable only at the stage when they are parts of electric motors, but no further duty can be levied when they are not separately identifiable as electric motors in the monoblock pump assembly.

Conclusion: Duty was not payable on the driving mechanism in the monoblock pump as an identifiable electric motor, and the Revenue's challenge failed.
