9015.90.01.10 - Of rangefinders

This HTS category, 9015.90.01.10, specifically covers parts and accessories that are designed for use with rangefinders. Rangefinders, as defined within Chapter 90, are instruments primarily used to determine distances, whether through optical, electronic, or other means. Therefore, this classification applies to components such as lenses, optical elements, electronic modules, casings, or mounting hardware that are integral to the function and construction of these distance-measuring devices.

It is crucial to distinguish this subcategory from its siblings. For instance, 9015.90.01.20 pertains to parts of theodolites and tachymeters, which are precision instruments for measuring horizontal and vertical angles. Similarly, 9015.90.01.30 covers parts for levels, used to establish horizontal planes. The distinction lies in the primary function of the parent instrument; this category exclusively addresses components related to instruments whose core purpose is distance determination.

As a leaf node, this classification does not have further subcategories. The classification of a part or accessory under this heading will depend on its direct and indispensable relationship with a rangefinder. Therefore, any item classified here must be demonstrably designed for and intended to be incorporated into or used in conjunction with an instrument whose principal function is rangefinding.
