8477.90.86.30 - Of blow-molding machines

This HTS classification, 8477.90.86.30, specifically designates parts and accessories designed for blow-molding machines. Blow-molding is a manufacturing process used to create hollow plastic items by inflating a heated plastic parison or preform within a mold. Therefore, this category encompasses components such as molds, clamping mechanisms, blowing pins, cutting devices, and control system parts that are integral to the operation of machines performing this specific plastic forming technique.

Distinguishing this category from its siblings is crucial for accurate classification. Unlike parts for injection-molding machines (8477.90.86.01) which are used to inject molten plastic into a mold, or parts for extruders (8477.90.86.20) which focus on pushing plastic through a die, 8477.90.86.30 applies exclusively to components of machinery that achieve product formation through air pressure inflating a plastic shape within a cavity. It also differs from parts for tire-forming machines (8477.90.86.40) and other miscellaneous parts (8477.90.86.95) used in rubber or plastic manufacturing.

As this is a leaf node within the HTS structure, there are no further subcategories that subdivide this classification. Classification under 8477.90.86.30 is determined by the direct functional relationship of the part to a blow-molding machine. Importers and exporters must ensure that the identified part's primary purpose and design are exclusively for, or are specially adapted for use with, blow-molding equipment to correctly utilize this HTS code.
