4011.20.10.15 - Other

This classification pertains to radial pneumatic tires specifically designed for on-the-highway use on buses and trucks. These tires are characterized by their radial construction, meaning the plies run radially across the tire from bead to bead, offering improved fuel efficiency, longer tread life, and better handling compared to bias-ply tires. "On-the-highway" specifies that these are intended for paved road surfaces, distinguishing them from off-road or specialized industrial applications.

This category is differentiated from its sibling, 4011.20.10.05 "Light truck," by its primary intended application. While both are pneumatic tires for trucks, this category specifically encompasses tires for larger, heavier-duty vehicles such as buses and larger commercial trucks, implying robust construction and load-bearing capacity suitable for continuous highway operation. The term "Other" at this level serves to capture all on-the-highway radial tires for buses and trucks that do not fall under more specific, unlisted sub-classifications, though in practice, this is often the final designation for such tires.

As this is a leaf node, there are no further subcategories under this specific HTS code. Therefore, classification within 4011.20.10.15 is determined by the definitive presence of radial construction, the intended use for buses and trucks, and their application on paved public roads. Importers should ensure that the tires meet these criteria to be correctly classified under this heading.
