9017.90.01.60 - Other

This HTS category, 9017.90.01.60, encompasses "Other" parts and accessories for drawing, marking-out, or mathematical calculating instruments, as well as instruments for measuring length in hand. This classification serves as a residual category for components that do not fit into more specific subheadings within 9017.90.01, but are nonetheless essential for the functioning of the instruments described in Chapter 9017. Examples could include specialized fasteners, housings, or decorative elements not otherwise specified, provided they are integral to the operation or construction of the covered instruments.

Unlike sibling categories such as 9017.90.01.05 or 9017.90.01.15, which are specifically linked to parts of particular subheadings within 9017.10, this "Other" category applies to parts not originating from those explicitly defined instrument types. Its scope is broader, encompassing any remaining parts and accessories for measuring or drawing instruments covered by the parent heading that haven't been assigned to a more precise classification.

As this is a leaf node, there are no further subdivisions within this category. Therefore, the primary consideration for classification here is to ensure that the part or accessory genuinely pertains to a measuring or drawing instrument under heading 9017 and does not fall into any more specifically defined part or accessory subheading within this tariff chapter or elsewhere in the Harmonized Tariff Schedule.
