4012.12.40 - Radial

This HTS classification covers retreaded tires specifically designed for use on buses and trucks, which are of the radial construction. These tires have undergone a process of re-treading, meaning new tread material has been applied to a previously used tire casing. The "radial" designation refers to the internal construction of the tire, where the plies are arranged radially across the tire from bead to bead, providing specific performance characteristics favored for heavy-duty applications.

This category is distinguished from its sibling, 4012.12.80 (Other), which would encompass retreaded tires for buses and trucks that are *not* of radial construction. Therefore, the key differentiator is the internal structural design of the tire (radial versus bias-ply or other construction methods). This sub-heading focuses exclusively on the radial type within the broader category of retreaded bus and truck tires.

Within this classification, further subdivisions exist to refine the classification of these radial tires. The subcategories differentiate based on the intended use of the tire, such as "On-the-highway truck and bus tires," and an "Other" category for any radial retreaded tires for buses or trucks that do not fit more specific descriptions. This granular breakdown allows for precise identification and tariff application based on the specific type and intended service of the retreaded radial tire.
