8477.90.86.40 - Of machines for forming pneumatic tires

This HTS classification, 8477.90.86.40, specifically covers parts for machinery designed for the manufacture of pneumatic tires. These parts are essential components used in the complex processes involved in shaping and assembling rubber and other materials to create tires for vehicles. Examples of such parts might include specialized molds, curing presses, bead setters, or components of automatic tire building machines. The defining characteristic for classification under this code is the direct and intended use in the production of pneumatic tires.

Distinguishing this category from its siblings is crucial for accurate classification. While 8477.90.86.01 covers parts for injection-molding machines, 8477.90.86.20 for extruders, and 8477.90.86.30 for blow-molding machines, this subcategory is distinct as it pertains solely to tire manufacturing equipment. The machinery covered by the sibling categories may share some general mechanical principles but are not specifically adapted for the unique requirements of tire production. Similarly, 8477.90.86.95, "Other parts," serves as a residual category for parts of rubber or plastics working machinery not elsewhere specified, whereas this code narrows the scope to a very specific industrial application.

As this is a leaf node in the HTS classification, there are no further subcategories under 8477.90.86.40. Therefore, classification decisions at this level will rely on meticulously ensuring that the part in question is indeed integral to, and exclusively used in, machines for forming pneumatic tires, and not a more general component or a part for a different type of rubber or plastics working machinery. The focus remains on the ultimate function and application of the machine from which the part originates.
