Tariff classification of metallizing wire turns on its ordinary meaning, not merely its welding-related use.

Metallizing wire used in gas metal arc welding and metallizing was held not to fall within the tariff entry for welding electrodes. The decisive point was that the wire was propelled through a gun and melted by flames, rather than functioning as an electrode through the passage of electricity. A tariff description cannot be widened by reference to possible welding-related use alone, and classification must follow the ordinary and technical meaning of the entry. On that reasoning, inclusion under Tariff Item 50 was not sustainable, and the assessee succeeded on the classification issue.

Issues: Whether metallizing wire, including coated and uncoated wire used in gas metal arc welding and metallizing, was classifiable as welding electrodes under Tariff Item 50 of the First Schedule to the Central Excises and Salt Act.

Analysis: The product was not shown to answer the description of welding electrodes merely because it could be put to a welding-related use. The decisive feature was that the wires were fired through a gun and melted by flames, not by the passage of electricity through the wire. The tariff entry specifically covered welding electrodes and could not be widened to include wires used for gas-based spraying or metallizing. A product's possible use in welding, without more, did not justify classification under the tariff item. The reasoning followed the view that tariff entries must be applied according to their own description and not enlarged by functional similarity alone.

Conclusion: The classification of the product under Tariff Item 50 was not sustainable and the assessee succeeded on this issue.

Ratio Decidendi: A tariff entry confined to welding electrodes cannot be extended to products that are merely used in a welding-related process but are not electrodes in their ordinary and technical sense.
