9620.00.30.40 - Of photogrammetrical surveying instruments and apparatus

This HTS subcategory, 9620.00.30.40, specifically classifies monopods, bipods, tripods, and similar portable support articles that are intended for use with photogrammetrical surveying instruments and apparatus. The primary function of these accessories is to provide a stable and adjustable platform for the precise measurement and mapping of real-world objects or environments using photographic techniques. The classification hinges on the designed purpose and the specific instruments with which they are intended to be used, focusing on their role in facilitating photogrammetry.

To distinguish this category from its siblings, it's important to note the precise application. While other subcategories at this level cover supports for rangefinders (9620.00.30.10), theodolites and tachymeters (9620.00.30.20), and levels (9620.00.30.30), this specific code is reserved for those designed to assist in photogrammetrical surveying. This differentiates them from general-purpose tripods or those intended for less specialized surveying equipment, emphasizing their integration into the photogrammetric workflow which often involves specialized cameras and data processing.

As this is a leaf node within the HTS structure, there are no further subcategories under 9620.00.30.40. Therefore, classification under this heading relies on a thorough understanding of the accessory's intended use and its compatibility with photogrammetrical surveying instruments. Considerations would include the physical design of the support (e.g., height adjustment mechanisms, mounting interfaces) and any accompanying documentation or product specifications that confirm its dedicated purpose for photogrammetric applications, distinguishing it from similar articles designed for other scientific or surveying disciplines.
