Tool classification for dies and punches remains intact when fitted into machine tools and used as replacement spares.

Blanking dies and blanking punches used in a die set were treated as tools designed to be fitted into machine tools under Item 51A(iii) of the Central Excise Tariff. Their essential tooling function in punching and shaping metal sheets was decisive, and the fact that they operated in conjunction with a punch press did not negate their character as tools. Classification was also not affected by their status as replacement spares, since wear-and-tear replacement does not alter the essential nature of functional machine parts. The goods were therefore correctly classified under Item 51A(iii).

Issues: Whether blanking dies and blanking punches, being component parts used in a die set and ultimately fitted into a punch press, were classifiable as tools designed to be fitted into machine tools under Item 51A(iii) of the Central Excise Tariff.

Analysis: The goods were held to perform the essential tooling function of punching and shaping metal sheets in the manufacture of battery plates. The fact that they were fitted through a die set and operated in conjunction with the punch press did not detract from their character as tools, since the tariff entry required only that the goods be designed to be fitted into machine tools and did not require independent functioning. Their character was also not altered by the fact that they were replacement spares, because wear-and-tear replacement of functional machine parts does not change their essential nature.

Conclusion: The goods were correctly covered by Item 51A(iii) of the Central Excise Tariff and the challenge to the classification failed.

Ratio Decidendi: Goods which perform the essential tooling function and are designed to be fitted into machine tools remain classifiable as tools under the relevant tariff entry even if they function only in conjunction with other components or are used as replacement spares.
