Quippo Energy Ltd. Vs Commissioner Of Central Excise Ahmedabad – II (Supreme Court of India)
From Genset to Power Pack: Transformation is Manufacture, Rules SC- Transformation + Marketability = Excise Duty Liability,
Factual Background
Quippo Energy Ltd. imported Gas Generating Sets (Gensets) comprising an engine coupled with an alternator. For ease of relocation & leasing purposes, these Gensets were placed inside steel containers & fitted with several additional components such as radiators, ventilation fans, oil tanks, silencers, pumps, valves, & electrical panels. The Revenue contended that this process amounted to “manufacture” under Section 2(f) of the Central Excise Act, 1944, making the final product—called Power Packs or Containerised Gensets—excisable. The company argued that the imported Gensets were already complete machines capable of generating electricity, & the additions were only accessories for convenience, not new products.
Tribunal’s Decision
The CESTAT held that the activity amounted to manufacture because:
1. Power Packs were distinct from imported Gensets, with separate identity & market recognition.
2. The process was incidental to completing the product under Section 2(f).
3. The imported Genset was incomplete without such assembly & thus fell under Note 6 of Section XVI of the Central Excise Tariff Act, 1985.
However, the Tribunal set aside demands for the extended limitation period, penalties, & confiscation, citing the assessee’s bona fide conduct & disclosure.
