7302.90.10.00 - Sleepers (cross-ties)

This HTS category, 7302.90.10.00, specifically classifies sleepers, also commonly known as cross-ties. These are structural components used in railway and tramway track construction, designed to be laid transversely to the rails and support them. Sleepers are typically made of iron or steel and serve the critical function of maintaining the gauge of the track and distributing the load from the rails to the ballast.

Within the broader category of "Railway or tramway track construction material of iron or steel," this classification is distinguished from its sibling, 7302.90.90.00, which is designated for "Other" materials of this type. While this sibling category would encompass any remaining iron or steel railway track construction materials not specifically enumerated elsewhere in heading 7302, 7302.90.10.00 is exclusively for sleepers. This distinction ensures that the precise identification and tariff treatment of sleepers are maintained.

As this is a leaf node within the HTS structure, there are no further subcategories under 7302.90.10.00. The classification is therefore complete at this level, focusing solely on the identification and tariffing of steel sleepers. When classifying, import and export professionals should confirm that the product is indeed a structural component intended for railway or tramway track construction and is composed of iron or steel.
