Functional test for capital goods: boiler-support structures qualified for Modvat credit as integral plant components.

Heavy fabricated columns and bracings used to support a boiler in a power plant were treated as capital goods under Rule 57Q because their function was integral to the effective use of the machinery and they were not mere civil construction. The court applied a functional test, holding that structural items serving as parts, accessories, or necessary supporting elements of essential plant machinery can qualify for Modvat credit. On that basis, denial of credit on the disputed items was unsustainable, and the assessee was held entitled to the credit.

Issues: Whether columns of heavy fabricated structures and bracings used to support a boiler in a power plant were eligible for Modvat credit as capital goods under Rule 57Q of the Central Excise Rules, 1944.

Analysis: The disputed items were not treated as mere civil construction because they served the technical function of supporting the boiler, which was an essential part of the plant. Items that function as parts, accessories, or supporting elements of machinery, and are necessary for its effective use, fall within the ambit of capital goods under Rule 57Q. The exclusion applied by the lower authorities to civil construction was therefore not apt on these facts.

Conclusion: The denial of Modvat credit on the columns of heavy fabricated structures and bracings was unsustainable and the issue was answered in favour of the assessee.

Final Conclusion: The appeal succeeded and the assessee was held entitled to Modvat credit on the disputed structural items.

Ratio Decidendi: Structural items used as support for essential machinery in a plant may qualify as capital goods or accessories where their functional role is integral to the machinery and they are not mere civil construction.
