Machine-specific dies as essential machinery parts stay in the main tariff entry, not the small-tools exclusion.

Imported thread rolling dies specially designed for Tsugami machines, made to precise specifications and usable only for those machines, were held to be component parts essential to the machinery's working. The court applied the principle that an article with no practical use apart from a particular machine remains classifiable under the main tariff entry for machinery components, and is not displaced into an exclusion clause merely because the entry illustratively refers to dies as small tools. On that basis, the dies fell within Item 72(3) and not Item 71(a), the customs classification was rejected, and refund relief followed.

Issues: Whether the imported thread rolling dies were classifiable under Item 72(3) of the First Schedule to the Indian Customs Tariff as component parts of machinery essential for its working, or under Item 71(a) as small tools falling within the exclusion clause.

Analysis: The dies were found to be specially designed for Tsugami thread rolling machines, made to particular specifications and sizes, and usable only for the working of those machines. The reasoning adopted the principle that goods which are component parts of machinery, essential to its operation and having a special shape or quality not required for any other purpose, do not cease to fall within the main part of Item 72(3) merely because the exclusion clause mentions dies as an illustrative small tool. On the facts, the imported dies were not ordinary tools of general use but machine-specific parts integral to the machine's function.

Conclusion: The imported thread rolling dies fell within Item 72(3) and not within the exclusion clause or Item 71(a); the classification adopted by the customs authorities was and the assessee was entitled to refund of excess duty.

Final Conclusion: The writ petitions succeeded on the tariff classification issue, and the impugned customs orders were quashed with consequential refund relief.

Ratio Decidendi: A machine-specific article specially designed as an essential component of machinery, having no practical use apart from that machinery, is classifiable as a component part under the relevant tariff entry and is not carried into an exclusion clause merely because the entry illustratively mentions a similar article as a small tool.
