9017.90.01.50 - Of articles of subheading 9017.30.80

This HTS classification pertains to parts and accessories specifically designed for instruments falling under subheading 9017.30.80. These instruments are typically those used for measuring length, intended for hand-held use, and not otherwise classified within Chapter 90. Examples of such measuring instruments include specialized measuring rods, tapes, micrometers, and calipers that are not specifically covered by other subheadings within heading 9017.

Distinguishing this category from its siblings relies on tracing the origin of the part or accessory. Each sibling subheading under 9017.90.01.xx is linked to a different parent subheading within heading 9017. Therefore, the classification of a particular part or accessory depends entirely on the specific type of measuring instrument (as defined by its originating subheading) it is intended to function with.

As this is a leaf node, there are no further subcategories. The classification is finalized at this level, indicating that the specific part or accessory is for a type of hand-held length measuring instrument classified under 9017.30.80. The precise nature of the part or accessory itself, such as its material composition or specific function (e.g., a replacement dial for a caliper, a measuring tape refill), is not a determining factor for classification beyond its intended use with the article of 9017.30.80.
