8412.90.90.35 - Other

This HTS category, 8412.90.90.35, covers parts for pneumatic power engines and motors that are not specifically classified elsewhere within this subheading. It is a residual category intended to capture a broad range of components and accessories associated with pneumatic machinery, provided they do not fit into more specific sub-classifications. Examples of items that might fall under this heading include specialized seals, fittings, mounting brackets, and internal components that are not explicitly defined as belonging to a linear-acting engine or motor part.

Distinguishing this category from its sibling, 8412.90.90.25 ("Of linear acting engines and motors"), is crucial. While both relate to parts of pneumatic power engines and motors, this category specifically excludes parts that are exclusively designed for or integral to the operation of linear pneumatic actuators. Therefore, if a part's primary function or design is intrinsically linked to a reciprocating or extending pneumatic mechanism, it would likely be classified under the sibling category.

As this node is a leaf node, there are no further subcategories to introduce. Classification within 8412.90.90.35 relies on a process of elimination, ensuring that the part in question is indeed a component of a pneumatic power engine or motor, and that it does not meet the criteria for any more specific HTS classification within Chapter 84, particularly within the broader categories of engines, motors, and their respective parts.
