Monoblock pump classification turns on whether an identifiable electric motor emerges from the unit's embedded prime mover components.

The embedded prime mover portion of a monoblock pump was not classifiable as an electric motor under Heading 85.01 of the Central Excise Tariff. The rotors and stators were fixed on the same shaft as the pump portion and functioned within the monoblock unit, so no electric motor emerged in an identifiable or commercially recognizable form. The tariff classification therefore depended on the actual form in which the component came into existence, and the departmental circular and earlier tariff position were treated as consistent with that approach. On that basis, the prime mover components were not independently classifiable as a motor, and the Revenue's appeals were rejected as without merit.

Issues: Whether the prime mover portion of a monoblock pump was classifiable under Heading No. 85.01 of the Schedule to the Central Excise Tariff Act, 1985.

Analysis: The rotors and stators used in monoblock pumps were fixed on the same shaft as the pump portion and functioned as the prime mover. They were not electric motors as commercially understood and marketed, and no electric motor in an identifiable form came into existence in the monoblock pump. The earlier tariff position and the departmental circular were noted to explain that rotors and stators used in monoblock pumps were not to be treated as independently emerging electric motors. Under the new tariff, while electric motors fell under Heading 85.01 and parts suitable for use with such machines under Heading 85.03, the factual position regarding the monoblock pump remained unchanged.

Conclusion: The prime mover portion of the monoblock pump was not classifiable under Heading No. 85.01, and the Revenue's appeals had no merit.

Ratio Decidendi: Where the electric motor does not emerge in an identifiable and commercially recognizable form in a monoblock pump, the embedded prime mover components are not classifiable as an electric motor under Heading 85.01.
