8477.90.86.01 - Of injection-molding machines

This HTS category, 8477.90.86.01, specifically covers parts and accessories for injection-molding machines. These machines are designed to form plastic or rubber products by injecting molten material into a mold. Consequently, the parts classified here are integral components used in the operation, maintenance, or repair of such machinery, including but not limited to molds, plungers, heating elements, and control systems specifically adapted for injection-molding processes.

This classification is distinct from its sibling categories which cover parts for other types of machinery within heading 8477. For instance, 8477.90.86.20 pertains to parts of extruders, which produce continuous profiles by forcing material through a die. Similarly, 8477.90.86.30 is for parts of blow-molding machines, used to create hollow plastic objects. 8477.90.86.40 addresses parts for machines specifically designed for forming pneumatic tires, and 8477.90.86.95 serves as a residual category for other miscellaneous parts not fitting into the more specific subcategories.

As a leaf node within the HTS structure, 8477.90.86.01 does not have further subcategories. Therefore, the focus for classification under this heading is on accurately identifying whether a part's design and function are intrinsically linked to injection-molding machinery. Classification relies on the specific role the part plays in the injection-molding process, ensuring it is not a general-purpose component but rather one engineered for this particular application.
