8413.91.90.85 - Other

This classification, HTS Code 8413.91.90.85, encompasses "Other" parts for pumps of subheading 8413.50.00 (other positive displacement pumps). This residual category is intended for components of these specific types of pumps that are not explicitly listed in other, more specific part subheadings within 8413.91. The scope of this classification is broad, covering a wide array of components essential for the operation of positive displacement pumps that fall outside of the categories designated for sucker rods.

Distinguishing this category from its sibling, 8413.91.90.65, is crucial. The sibling category specifically covers "Sucker rods of a kind described in statistical note 3 to this chapter," which are primarily used in reciprocating pumps for extracting oil. HTS Code 8413.91.90.85, conversely, includes all other parts not fitting that specific definition. Therefore, if a pump part is not a sucker rod as defined by the statistical note, it would likely fall under this "Other" category, provided it pertains to a positive displacement pump covered by subheading 8413.50.00.

As this is a leaf node within the HTS, there are no further subcategories. The classification relies on the exclusion principle: if a part is for a positive displacement pump and isn't specifically enumerated elsewhere, it is classified here. Examples of items that may be classified under this subheading include impellers, shafts, seals, bearings, housings, and various internal components specifically designed for the operation of pumps classified under subheading 8413.50.00. The key is to verify the pump's type and then ensure the part is not more precisely classified elsewhere.
