7228.60.10.30 - Of ball-bearing steel

This HTS category, 7228.60.10.30, specifically classifies bars and rods of other alloy steel that are manufactured from ball-bearing steel. Ball-bearing steel is a specialized alloy steel characterized by its high carbon content and alloying elements such as chromium, which impart exceptional hardness, wear resistance, and toughness. These properties make it ideally suited for the production of high-precision components like anti-friction bearings, races, and other parts subjected to significant stress and friction.

Distinguishing this category from its sibling, 7228.60.10.60 "Other," is crucial. While the sibling category encompasses a broader range of alloy steel bars and rods not specifically defined by their material composition or intended use in bearing applications, this classification is narrowly focused on those made of ball-bearing steel. This distinction is vital for accurate tariff application, as the unique metallurgical properties of ball-bearing steel necessitate specific manufacturing processes and result in distinct end-use applications.

As this is a leaf node, there are no further subcategories within 7228.60.10.30. Therefore, classification within this code relies entirely on the material being identified as ball-bearing steel and the physical form being a bar or rod. Importers and exporters should ensure that documentation clearly indicates the material composition and its classification as ball-bearing steel to support the correct tariff entry.
