7229.90.50.08 - Other

This HTS category, 7229.90.50.08, specifically classifies round wire made from other alloy steel that meets very precise metallurgical and functional criteria. To fall into this subcategory, the wire must have a diameter of 1.6 mm or less. Furthermore, its composition is strictly defined: it must contain by weight less than 0.20 percent of carbon, and either more than 0.3 percent of nickel or more than 0.08 percent of molybdenum. Crucially, the wire must also be suitable for electric arc welding, indicating a specific intended application and metallurgical properties that facilitate this process.

This classification differentiates itself from its sibling category, 7229.90.50.06, by the absence of copper plating or coating. While both fall under "Other" wire of other alloy steel with specific characteristics, the presence or absence of copper as an external treatment is the distinguishing factor. This current category encompasses only the uncoated, unplated alloy steel wire that meets the specified diameter, carbon, nickel, and molybdenum content, and is designed for electric arc welding.

As this is a leaf node within the HTS, there are no further subcategories to explore. The classification is complete at this level, meaning any wire meeting all the detailed criteria described above will be classified here. Examples of such wire could include specialized welding filler materials for high-performance alloys that require precise control over nickel or molybdenum content and a low carbon base, all within a fine diameter suitable for arc welding applications.
