Cold-Formed or Cold-Finished Bars and Rods of Other Alloy Steel

Ball-bearing steel is a specific high-carbon chromium alloy grade (commonly 52100-type) engineered for rolling contact fatigue resistance, and it has its own dedicated line (7228501010). Other tool steel bars not classified as high-speed steel fall into separate lines based on cross-sectional shape and dimension. Importers should verify the alloy designation on the mill certificate against the applicable ASTM or equivalent standard to confirm the correct line.

Section 232 tariffs apply broadly to steel imports, including cold-finished alloy bars. Sweden and Slovenia, as EU member states, have been subject to evolving Section 232 arrangements between the US and the EU; the applicable treatment depends on the specific agreement in effect at the time of entry. Importers should confirm current status with a licensed customs broker before shipment.
