Trade parlance governs tariff classification where tungsten carbide pellets are only components, not complete tools or dies.

Classification under Tariff Item 51A(iii) turned on whether the article was itself a complete tool or die in trade and technical parlance. Tungsten carbide pellets were found to be only components of a die, requiring shank fitting and hard steel casing before they could function, so they were not complete tools or dies by themselves. Because the tariff entry covered tools and dies, not their parts or components, the pellets fell outside the entry and were not classifiable as such.

Issues: Whether tungsten carbide pellets, before shank fitting and without being a complete die or tool by themselves, were classifiable as tools under Tariff Item 51A(iii) of the erstwhile Central Excise Tariff.

Analysis: Tariff Item 51A(iii) covered tools designed to be fitted into hand tools, machine tools, or tools falling under the specified sub-item, including dies for wire drawing, extrusion dies for metals and rock drilling bits. The decisive consideration was whether the article itself was a complete tool or die, rather than merely a component of one. The material before the Tribunal showed that the pellet was only a component of a die and required shank fitting in a hard steel casing before it could function as a die. The item was therefore not a complete tool or die by itself. The Tribunal also accepted the technical literature and trade understanding that the pellet was a component intended for use in dies, and that the tariff entry covered tools and dies, not their parts or components.

Conclusion: The pellets were not classifiable under Tariff Item 51A(iii) as tools or dies, and the Revenue appeal failed.

Final Conclusion: Classification depended on the article being a complete tool or die as understood in trade and technical parlance, not merely a functional component intended for later assembly.

Ratio Decidendi: An article that is only a component of a die and cannot function as a complete tool or die by itself is not classifiable under a tariff entry covering tools and dies, and not their parts or components.
