Last updated: August 2026 dataSubject to Section 232 tariffs on steel imports, these precision-engineered track components — switch blades, crossing frogs, and point rods — are the mechanical heart of rail junction systems, directing rolling stock between diverging lines. The entire heading consolidates into a single 10-digit tariff line (7302300000), meaning all variants of iron or steel crossing pieces enter under one classification regardless of design or gauge. Importers should confirm whether goods meet the dimensional and metallurgical specifications required by Class I railroads or transit authorities, as misclassification between this heading and general structural steel shapes is a recurring audit issue.

Crossing frogs are the fixed V-shaped assemblies at the intersection of two rails that guide wheel flanges through the crossing point. They are classified under 7302300000 along with switch blades and point rods, all of which are purpose-built for directing or guiding rail traffic at junctions — distinguishing them from plain rail sections (7302) or fasteners (7318).
Yes. Iron and steel articles in Chapter 73, including switch blades and crossing frogs, are broadly subject to Section 232 tariffs. Importers should verify current applicability and any country-specific exclusions or quota arrangements with a licensed customs broker before entry.
