8477.90.86.20 - Of extruders

This HTS classification, 8477.90.86.20, specifically covers parts and accessories designated for extruders used in the working of rubber or plastics, or in the manufacture of products from these materials. Extruders are machinery designed to force molten or softened material through a die to create continuous profiles, such as pipes, films, filaments, or sheets. Therefore, this category encompasses components like screws, barrels, dies, screens, and cutters that are integral to the functioning of these extrusion machines.

It is crucial to distinguish this category from its siblings. While 8477.90.86.01 covers parts for injection-molding machines, and 8477.90.86.30 covers parts for blow-molding machines, this classification is exclusively for parts of extruders. Similarly, 8477.90.86.40 pertains to parts for tire-forming machinery, and 8477.90.86.95 is a residual category for other parts within the broader "Parts" heading for machinery under 8477. The defining characteristic for classification under 8477.90.86.20 is the intended use of the part with an extrusion machine.

As this is a leaf node in the HTS classification, there are no further subcategories. Classification within 8477.90.86.20 is determined by the specific function and design of the part, confirming its essential role in the extrusion process. Importers and exporters should ensure that the parts they are declaring are indeed manufactured for and utilized with extrusion equipment to ensure accurate customs declarations.
