9902.15.08 - Cold-formed wire of nickel-titanium alloy, presented in coils, with round cross section, with a diameter of 0.1778 mm or more but not over 0.6350 mm (provided for in subheading 7505.22.10)

This HTS classification, 9902.15.08, specifically covers cold-formed wire made from a nickel-titanium alloy. The wire must be presented in coils and possess a round cross-section within a defined diameter range, from 0.1778 mm up to and including 0.6350 mm. This category is a temporary measure, as indicated by its placement within Chapter 99, and provides specific tariff treatment for this particular product. It is important to note that while this classification describes a specific type of wire, its ultimate tariff treatment is based on its provision for in subheading 7505.22.10 of the permanent tariff schedule.

As this classification resides within Chapter 99, it represents a departure from the standard HTS structure and is used for specific, often temporary, trade policy or regulatory purposes. The sibling categories at the Chapter 99 level would also be related to temporary legislation, trade agreement modifications, or specific import restrictions, rather than the broad commodity classifications found in earlier chapters of the HTS. Therefore, direct comparison to categories like "Live horses" or "Live bovine animals" is not applicable, as those fall under entirely different, permanent chapters dealing with agricultural products.

Since HTS code 9902.15.08 is a leaf node, it does not have further subcategories. Classification is determined solely by meeting the specific criteria outlined in its description: the material composition (nickel-titanium alloy), the form (cold-formed wire in coils), and the precise diameter of the round cross-section. Compliance with these physical and presentation requirements is essential for accurate classification under this provision.
