9620.00.30.50 - Of seismographs 🖩

This HTS classification, 9620.00.30.50, specifically covers accessories, such as stands, tripods, or mounts, that are designed for use with seismographs. Seismographs are instruments used to detect and record seismic waves, commonly employed in earthquake monitoring, geological surveys, and hydrocarbon exploration. Therefore, this subheading applies to those articles that are integral to the stable positioning and operation of such seismic recording equipment.

Distinguishing this category from its siblings, we find that other classifications within 9620.00.30 cover accessories for different types of surveying and geophysical instruments. For instance, items classified under 9620.00.30.10 are for rangefinders, 9620.00.30.20 for theodolites and tachymeters, and 9620.00.30.30 for levels. This subheading's exclusivity to seismograph accessories ensures that equipment intended for seismic data acquisition is correctly identified and separated from accessories for other, albeit related, scientific instruments.

As this is a leaf node within the HTS, there are no further subdivisions under 9620.00.30.50. The classification concludes at this point, meaning all articles falling within this description are consolidated under this specific HTS code. Therefore, the primary focus for classification under this code is to confirm that the accessory's intended purpose and design are demonstrably for use with seismographs, rather than any other type of instrument.
