Tariff classification depends on actual function and design: glandnut is a fastener, while bonnet and union remain valve parts.

Tariff classification turned on the actual function and design of the article. Glandnut, being threaded and performing a fastening function while also guiding the stem, was treated as a fastener under the old tariff and sub-heading 8313.10 under the new tariff. Bonnet and union, however, were found to lack any fastening function: the bonnet remained a valve body component carrying the operating mechanism, and the union served only to house the gland and packing. They therefore continued as parts of valves and cocks, with classification sustained on that basis.

Issues: (i) Whether glandnut was classifiable as a fastener under Tariff Item 52 of the old tariff and under sub-heading 8313.10 of the new tariff; (ii) whether bonnet and union were classifiable as fasteners or remained classifiable as parts of valves and cocks.

Issue (i): Whether glandnut was classifiable as a fastener under Tariff Item 52 of the old tariff and under sub-heading 8313.10 of the new tariff.

Analysis: The article examined showed threading and performed a fastening function. It also served as a cap with a hole guiding the stem in alignment. On that functional basis, it answered the description of a fastener rather than merely a valve part.

Conclusion: Glandnut was classifiable under Tariff Item 52 of the old tariff and under sub-heading 8313.10 of the new tariff, in favour of Revenue.

Issue (ii): Whether bonnet and union were classifiable as fasteners or remained classifiable as parts of valves and cocks.

Analysis: The bonnet was found to be a part attached to the valve body carrying the operating mechanism, but not designed for fastening. The union was found to provide space around the stem to contain the gland and gland packing, and it too lacked any fastening function.

Conclusion: Bonnet and union were not classifiable as fasteners and their classification as parts of valves and cocks was upheld, in favour of the assessee.

Final Conclusion: The classification dispute succeeded only in respect of glandnut, while the classification of bonnet and union in favour of the assessee was maintained, resulting in a partly allowed appeal.

Ratio Decidendi: For tariff classification, the decisive test is the actual function and design of the article; where the article serves a fastening function it falls under the fastener entry, but articles lacking such function remain classifiable according to their specific character as parts.
