7302.10.10.35 - Standard tee rails over 30 kg per meter

This HTS classification, HTS Code 7302.10.10.35, specifically addresses new, heat-treated rails made of iron or nonalloy steel that weigh over 30 kilograms per meter. These are standard tee rails designed for use in railway or tramway track construction. The "new" designation signifies that these are unused articles, and the "heat-treated" criterion is a key physical characteristic that differentiates them within the broader "of iron or nonalloy steel" category.

At this level, the primary sibling category is "Other," which would encompass rails that are not new or not heat-treated, such as those that are used, refurbished, or have undergone different manufacturing processes. The emphasis on a weight exceeding 30 kilograms per meter is a crucial physical specification for identifying these heavy-duty rails, distinguishing them from lighter weight rail profiles that might be used for lighter track systems or other applications.

As this is a leaf node, there are no further subcategories. The classification is finalized at this point based on the material (iron or nonalloy steel), condition (new), treatment (heat-treated), and specific weight characteristic (over 30 kg per meter). Examples of goods falling under this code would include new, heat-treated sections of standard railway rail intended for heavy-duty freight or passenger lines.
