9030.90.89.61 - Other

This HTS category, 9030.90.89.61, encompasses "Other" parts and accessories for instruments and apparatus designed for measuring or checking electrical quantities, as well as those for detecting ionizing radiations. This broad designation applies to components and accessories that do not fall under more specific subheadings within the 9030.90.89 series. Classification here is determined by exclusion, meaning items are placed in this category if they do not meet the criteria for other specified parts and accessories.

The distinction from sibling categories lies in the specific upstream product they are intended for. Siblings such as 9030.90.89.11 and 9030.90.89.21 are dedicated to parts and accessories of specific instrument types outlined in subheadings 9030.20 and 9030.31, respectively. Therefore, 9030.90.89.61 is for any remaining parts or accessories for electrical measuring instruments or radiation detectors that are not directly linked to those specifically enumerated predecessor subheadings.

As this node represents a leaf node in the HTS structure, there are no further subdivisions. This means that any part or accessory fitting the general description and not classified elsewhere within 9030.90.89 will ultimately be classified under this residual category. Examples could include generic screws, enclosures, or wiring harnesses for a variety of electrical measuring or radiation detecting devices, provided they are not specifically designated for a particular type of instrument covered by a preceding sibling category.
