8477.30.00.00 - Blow-molding machines

HTS Code 8477.30.00.00 specifically covers blow-molding machines, which are designed to shape hollow plastic or rubber products through the inflation of a molten plastic or rubber parison within a mold cavity. These machines are instrumental in the production of a wide array of items such as bottles, containers, and various hollow articles.

This classification is distinct from other machinery for working rubber or plastics found in heading 8477. For instance, injection-molding machines (8477.10) force molten material into a closed mold, while extruders (8477.20.00) push material through a die to create continuous profiles. Vacuum-molding and thermoforming machines (8477.40.01.00) utilize heat and pressure differences to shape pre-formed sheets. The defining characteristic of blow-molding machines is the use of air or gas pressure to expand a parison against the mold walls.

As 8477.30.00.00 is a leaf node within the HTS structure, there are no further subcategories under this specific code. Therefore, classification within this category will rely on the precise application and design features of the machinery, ensuring it performs the core function of blow-molding as distinguished from other plastic and rubber working processes.
