Excise valuation of pump shaft turns on functional attachment, with the shaft treated as part of the exempt mono-block pump.

For excise valuation, a component must be classified by its actual functional and structural attachment to the relevant product. The shaft manufactured for use in a mono-block pump was treated as part of the exempt pump assembly, not as part of the stator or rotor of the motor. As no material showed that the shaft belonged to the dutiable motor components, its value could not be included in their assessable value. The differential duty demand was therefore unsustainable, and the assessee's position prevailed on that issue.

Issues: Whether the shaft manufactured and used in the mono-block pump was to be treated as part of the stator or rotor for the purpose of central excise duty, or as part of the exempt mono-block pump.

Analysis: The exempted product was the mono-block pump. The demand proceeded on the premise that the shaft formed part of the stator or rotor and that its value had to be included in the assessable value of those dutiable components. No material was shown to establish that the shaft was part of the stator or rotor rather than part of the mono-block pump. The functional description of the pump indicated that the shaft served the mono-block assembly and not the motor assembly comprising the stator or rotor.

Conclusion: The shaft was part of the mono-block pump and not part of the stator or rotor. The demand for differential duty was therefore unsustainable and the assessee succeeded on this issue.

Final Conclusion: The impugned orders confirming the duty demand were set aside and the appeals were allowed.

Ratio Decidendi: For excise valuation, a component must be classified according to its actual functional and structural attachment to the excisable product, and a duty demand cannot be sustained in the absence of material showing that the item belongs to the dutiable article rather than the exempt assembly.
