7229.90 - Other:

This HTS category, 7229.90, encompasses wire made from alloy steel that does not fall under the specific classifications for silico-manganese steel. It broadly covers a range of alloy steel wires where the alloy composition is not explicitly defined by a distinct subcategory. The primary characteristic of goods classified here is their composition of iron and steel with added elements beyond carbon, such as chromium, nickel, molybdenum, vanadium, or tungsten, to impart specific properties like increased strength, hardness, corrosion resistance, or heat resistance.

Distinguishing this category from its sibling, 7229.20.00, is crucial. While 7229.20.00 is specifically reserved for wire made of silico-manganese steel, this category, 7229.90, serves as a residual classification for all other alloy steel wires. Therefore, if a wire exhibits alloy properties but is not predominantly characterized by silicon and manganese in its alloy composition, it would likely fall under 7229.90.

Within this category, further distinctions are made through its subcategories. The primary subdivision addresses wire of high-speed steel, a specific type of alloy steel known for its ability to retain hardness at high temperatures, commonly used in cutting tools. Following this specific exclusion, the remaining "Other:" subcategory acts as a further residual, capturing any alloy steel wire not classified as silico-manganese or high-speed steel.
