4013.90.10.00 - Designed for tires provided for in subheadings 4011.70.00, 4012.19.20, 4012.20.15 and 4012.20.45

This HTS category, 4013.90.10.00, specifically covers inner tubes made of rubber that are designed for use with tires classified under subheadings 4011.70.00 (tires for agricultural or forestry machinery), 4012.19.20 (retreaded or used tires of rubber, of a kind used on motor vehicles), 4012.20.15 (new pneumatic tires of rubber, of a kind used on agricultural or forestry machinery), and 4012.20.45 (new pneumatic tires of rubber, of a kind used on airplanes). The critical distinguishing factor for this classification is the intended application as an inner tube for these particular types of tires.

Within the broader category of "Inner tubes, of rubber: Other," this subheading is distinct from its sibling, 4013.90.50, which encompasses all other rubber inner tubes not meeting the specific design criteria for the tires listed in this subheading. Therefore, classification here hinges on ensuring the inner tube is manufactured with the specifications and for the purpose of fitting into the aforementioned tire categories.

As this is a leaf node within the HTS structure, there are no further subcategories. Classification at this level is definitive based on the type of tire for which the rubber inner tube is intended. Examples of goods falling under this classification would include inner tubes for tractors, harvesters, certain types of trucks used in forestry, and specific aircraft tires where separate inner tubes are utilized rather than tubeless systems.
