7228.10.00 - Bars and rods, of high-speed steel

This HTS category specifically classifies bars and rods manufactured from high-speed steel. High-speed steel is a type of tool steel renowned for its hardness, wear resistance, and ability to maintain its cutting edge at high temperatures, making it ideal for cutting tools, drills, and milling cutters. The classification hinges on the material composition, distinguishing these from general alloy steels or non-alloy steels.

When differentiating from sibling categories, it's crucial to note that 7228.10.00.00 is exclusively for "high-speed steel." Other sibling categories under the broader heading "Other bars and rods, not further worked than hot-rolled, hot-drawn or extruded:" or "Angles, shapes and sections, of other alloy steel" would encompass items made from different alloy steels (like silico-manganese steel) or those not specifically identified as high-speed steel, even if they share similar forms. For example, 7228.20.00.00 covers silico-manganese steel, which is a distinct alloy with different properties and applications.

Within this high-speed steel classification, subcategories exist to further refine the treatment of the bars and rods. The distinction typically lies in the processing applied after initial forming. Subcategories such as "Not cold-formed" and "Cold-formed" differentiate based on whether the bars and rods have undergone additional mechanical processes at lower temperatures to achieve tighter tolerances, improved surface finish, or enhanced mechanical properties. This allows for precise tariff application based on the level of finishing and the resulting suitability for specific end uses.
