Manufacture and tariff classification of fabricated pipes upheld as dutiable goods before incorporation into a power plant

Fabricated pipes formed by bending and welding steel sheets were held to be a distinct commercial product with a new name, character and use, so the process amounted to manufacture and the pipes became excisable goods before incorporation in the plant. They were classifiable under Heading 7305 as pipes and tubes, not under Heading 7308 as parts of structures, because later use in a power project or embedding at site did not change their tariff identity. The turnkey-project circular did not displace duty on components that came into existence before assimilation into the structure, so duty remained payable on the individual pipes.

Issues: Whether the fabricated pipes came into existence as excisable goods before being fitted into the plant, whether they were classifiable as pipes under Heading 7305 or as parts of structures under Heading 7308, and whether the Board's circular on turnkey projects displaced duty liability.

Analysis: The pipes were produced by bending and welding steel sheets into a distinct product with a new name, character and use, so the process amounted to manufacture. The fact that the pipes were made to design and specification for a power plant, or were later used in erection and embedded at site, did not make them structural goods. Pipes and tubes of the relevant diameter remain covered by Heading 7305, and the classification under Heading 7308 for structures and parts of structures was held inapplicable. The circular on turnkey projects did not exempt the individual pipes, because the relevant clarification preserved duty on components that come into existence before assimilation in a structure.

Conclusion: The fabricated pipes were excisable goods classifiable under Heading 7305 and not under Heading 7308, and the Revenue's appeal succeeded.

Final Conclusion: The impugned order was set aside and the demand was restored in favour of Revenue.

Ratio Decidendi: Where a distinct commercial product emerges before incorporation at site, it is manufacture and remains dutiable as goods notwithstanding later use in a plant or project, and classification must follow the specific tariff heading for the product rather than the heading for structures.
