4012.12 - Of a kind used on buses or trucks:

This HTS category, 4012.12, specifically encompasses retreaded or used pneumatic rubber tires that are designed for and typically used on buses or trucks. This classification focuses on tires that have undergone a retreading process, meaning they have had new tread applied to a used tire casing. The key distinguishing factor for this subheading is the intended application for heavy-duty commercial vehicles, such as long-haul trucks, delivery vans, and passenger buses, differentiating them from tires intended for smaller passenger vehicles, aircraft, or other specialized uses.

When classifying under 4012.12, it is crucial to distinguish these goods from their siblings. Subheading 4012.11 covers retreaded tires for motor cars, which are generally smaller and designed for lighter loads and passenger transport. Similarly, 4012.13.00 specifically addresses retreaded tires for aircraft, which have unique construction and performance requirements. The residual category, 4012.19, captures any other retreaded tires not falling into the aforementioned specific applications.

The subdivisions within 4012.12, namely 4012.12.40 for radial tires and 4012.12.80 for other types, further refine the classification based on the tire's construction. Radial tires are characterized by their carcass plies running radially across the tire, offering distinct performance characteristics like better fuel efficiency and handling. "Other" would encompass bias-ply tires or any other construction methods not classified as radial. This distinction is important for understanding tire specifications and potential trade statistics.
