8424.90.10.00 - Of simple piston pump sprays and powder bellows

HTS code 8424.90.10.00 specifically classifies parts for simple piston pump sprays and powder bellows. These are essential components designed to facilitate the projection or dispersion of liquids or powders through a piston-driven mechanism. Examples include pistons, cylinder assemblies, pump bodies, and associated seals or linkages that are integral to the operation of such spraying or bellows devices.

This category is distinct from its sibling categories by its focus on a particular type of projection mechanism. While 8424.90.05.00 covers parts for fire extinguishers, and 8424.90.20.00 pertains to parts for sand blasting machines, 8424.90.10.00 is exclusively for the components of simple piston-powered sprayers (such as garden sprayers or hand-pumped aerosol dispensers) and powder bellows (used for dusting or inflation). The remaining sibling, 8424.90.90, encompasses all other parts not specifically enumerated elsewhere within the 8424.90.00 range.

As this is a leaf node in the HTS classification, there are no further subcategories. Classification under this heading hinges on the part's direct and indispensable function in the construction or operation of a simple piston pump spray or powder bellows apparatus. The material of the part is generally secondary to its design and intended use within these specific types of machinery.
