7228.60.10 - Of tool steel (other than high-speed steel)

This HTS category, 7228.60.10, specifically classifies "Other bars and rods of other alloy steel," excluding high-speed steel. These are solid, elongated forms of alloy steel, meaning they contain elements beyond iron and carbon in quantities sufficient to impart specific properties. This category encompasses bars and rods used for a wide range of applications where properties like enhanced strength, hardness, or corrosion resistance are required, but not to the extreme levels associated with high-speed steel.

Within the broader grouping of "Other bars and rods of other alloy steel; angles, shapes and sections, of other alloy steel; hollow drill bars and rods, of alloy or nonalloy steel," this particular subheading focuses exclusively on the "bars and rods" subgroup. It distinguishes itself from potential sibling categories by its specific form (bars and rods) and material composition (other alloy steel). The term "other alloy steel" is key here, denoting alloys that do not fall into more specialized classifications, such as high-speed steel, which would be classified elsewhere.

The subcategories under 7228.60.10 further refine the classification based on the intended application or specific composition of the alloy steel. The distinction between "Of ball-bearing steel" (7228.60.10.30) and "Other" (7228.60.10.60) is crucial for accurate tariff application. Ball-bearing steel, a specialized alloy known for its high compressive strength and wear resistance, has its own designated subheading. All other bars and rods of alloy steel not meeting the specific criteria for ball-bearing steel or high-speed steel fall under the residual "Other" classification.
