Cold storage depreciation rules: building treated as factory building and thermocole insulation held to be plant under tax law.

A cold storage building used for refrigeration and preservation of goods can qualify as a factory building for depreciation purposes, because the cold storage activity involves a manufacturing process in the wider statutory sense. Applying the concept of "factory" and "manufacturing process" from the Factories Act for guidance, the building was treated as a factory building and depreciation was allowed accordingly. Thermocole insulation formed an integral part of the cold storage installation and the air-conditioning arrangement in the freezing chamber, so it fell within the inclusive definition of "plant" in section 43(3) and qualified for the higher depreciation rate. Both questions were answered in favour of the assessee.

Issues: (i) Whether the cold storage building was a factory building eligible for depreciation allowance under the Income-tax Act. (ii) Whether thermocole insulation formed part of "plant" within the meaning of section 43(3) of the Income-tax Act, 1961.

Issue (i): Whether the cold storage building was a factory building eligible for depreciation allowance under the Income-tax Act.

Analysis: The term "factory building" was not defined in the Act, so the Court looked to the statutory concept of "factory" and "manufacturing process" in the Factories Act, 1948 for guidance. It held that cold storage operations involve a process of treatment and preservation of goods with the aid of refrigeration, which falls within the concept of manufacturing process. The building was also treated in practice as a factory under the Factories Act and had long been so regarded without contrary authority.

Conclusion: The cold storage building was a factory building and the question was answered in favour of the assessee.

Issue (ii): Whether thermocole insulation formed part of "plant" within the meaning of section 43(3) of the Income-tax Act, 1961.

Analysis: Section 43(3) contains an inclusive definition of "plant". The thermocole insulation was an integral part of the cold storage installation and functioned as part of the air-conditioning arrangement used in the freezing chamber. On that basis, it was covered by the statutory meaning of plant and entitled to the higher rate of depreciation.

Conclusion: Thermocole insulation was plant within section 43(3), and the question was answered in favour of the assessee.

Final Conclusion: Both referred questions were decided for the assessee, sustaining the Tribunal's view on depreciation for the cold storage building and thermocole insulation.

Ratio Decidendi: A cold storage building used in a process of refrigeration and preservation of goods can qualify as a factory building, and an inclusive statutory definition of plant extends to integral components of the cold storage installation used as part of the air-conditioning system.
