9015.20.80.00 - Other 🖩

This HTS category, "Other," within the classification for theodolites and tachymeters, serves as a residual grouping. It encompasses theodolites and tachymeters that do not fit into the more specific "Electrical" category. These instruments are fundamental tools for precise angular and linear measurements in surveying and related fields, utilizing optical and mechanical principles for their operation. Examples include non-electrical optical theodolites and traditional mechanical tachymeters, where the primary mechanisms for measurement are not electrically powered.

The distinction from its sibling category, 9015.20.40.00 "Electrical," is crucial. While "Electrical" covers theodolites and tachymeters that incorporate electronic components, digital displays, or operate via electrical power, this "Other" category is reserved for instruments that rely solely on purely mechanical or optical systems for their functionality. This difference in operational principle is the primary classification determinant.

As this is a leaf node, there are no further subcategories to introduce. Therefore, classification into this heading is contingent on the instrument being a theodolite or tachymeter and not possessing any electrical operational features. The focus for classification under this heading is on the absence of electrical components and the instrument's core function in performing precise angular and distance measurements through non-electrical means.
