7228.20.10.00 - Not cold-formed

This HTS category, 7228.20.10.00, specifically covers bars and rods of silico-manganese steel that have not undergone a cold-forming process. Silico-manganese steel is an alloy steel characterized by its significant content of silicon and manganese, which imparts desirable properties such as increased strength, hardness, and elasticity. This classification applies to products that have been hot-rolled, hot-extruded, or otherwise processed at elevated temperatures, maintaining their structural integrity without the dimensional changes associated with cold working.

The key differentiator for this category, as indicated by its sibling, 7228.20.50.00, lies in the manufacturing process. While this category is for "Not cold-formed" bars and rods, its sibling designation signifies products that have been subjected to cold drawing, cold rolling, or other cold-forming techniques. This typically results in tighter dimensional tolerances, improved surface finish, and potentially altered mechanical properties compared to their hot-formed counterparts.

As this is a leaf node within the HTS structure, there are no further subcategories to introduce. Therefore, classification under 7228.20.10.00 relies solely on the material composition (silico-manganese steel) and the fact that the bars and rods were not cold-formed. Examples of goods that would fall under this classification include hot-rolled bars used for manufacturing springs, automotive components, or machine parts where the inherent properties of silico-manganese steel are required and precise cold-formed dimensions are not a prerequisite.
