Integrated EMU classification rejected separate trailer-car treatment where propulsion depended on the full railway unit.

Imported Electrical Multiple Units were treated as a single integrated system for classification because propulsion depended on the coordinated function of the drive motor cars and trailer cars. The trailer cars carried essential equipment for power drawing and conversion, and the drive motor cars could not operate independently as self-propelled units. Separate invoicing and valuation did not change the functional identity of the EMU for tariff purposes. The HS Committee view and the foreign advance ruling cited in the text also supported classification of the EMU as one unit rather than splitting the trailer cars for separate non-self-propelled classification. The demand and penalties were therefore held unsustainable.

Issues: Whether the imported Electrical Multiple Units comprising drive motor cars and trailer cars were to be treated as an integrated unit for classification under the self-propelled railway coach heading, and whether the trailer cars could be classified separately as non-self-propelled coaches so as to deny the claimed exemption.

Analysis: The arrangement and technical function of the EMU showed that propulsion depended on the coordinated operation of the drive motor cars and the trailer cars as a single system. The trailer cars carried essential equipment for drawing and converting power, while the drive motor cars alone could not operate as self-propelled units. The separate invoicing and valuation of the components did not alter their integrated character for classification. Support was also drawn from the HS Committee view and the foreign advance ruling relied upon, both treating the EMU as one functional unit and not splitting the trailer cars for classification.

Conclusion: The EMUs had to be classified and assessed as an integrated unit under the self-propelled heading, and the trailer cars could not be separated for classification under the non-self-propelled heading. The impugned demand and penalties were unsustainable, and the appeals succeeded.
