7229.20.00.90 - Other

This HTS category, 7229.20.00.90, encompasses "Other" wire made from silico-manganese steel that does not fall into more specific subcategories. Silico-manganese steel is a type of alloy steel characterized by its iron base with significant additions of silicon and manganese. These elements are added to enhance properties such as strength, hardness, elasticity, and toughness, making the steel suitable for various demanding applications.

To understand the scope of this category, it is crucial to differentiate it from its sibling categories. The sibling category described, "Round, with a diameter of less than or equal to 1.6 mm, containing by weight less than 0.20 percent of carbon, more than 0.9 percent of manganese, and more than 0.6 percent of silicon, and suitable for electric arc welding," represents a very specific subset of silico-manganese steel wire. This current category, 7229.20.00.90, serves as a residual classification for all other silico-manganese steel wires that do not meet the precise chemical composition and physical characteristics outlined in its sibling. Therefore, it would include wires of different diameters, carbon content, or those not intended for electric arc welding, as long as they are classified as silico-manganese steel wire.

As this node represents a leaf node within the HTS, there are no further subcategories to introduce. Classification within this code is determined by the specific composition of silico-manganese steel and the exclusion from more narrowly defined categories. Examples of goods that would fall under this classification could include silico-manganese steel wire used in the manufacturing of springs, coils, or other mechanical components where the specific properties of silico-manganese steel are required, but the wire does not meet the stringent criteria of the sibling category.
