9022.90.05.00 - Radiation generator units

This HTS subheading, 9022.90.05.00, specifically covers radiation generator units designed for use within apparatus utilizing X-rays or other ionizing radiations. This encompasses the core components responsible for producing the radiation beam itself, such as X-ray tubes, isotope sources, or other specialized generators. The classification is driven by the fundamental function of generating the ionizing radiation, irrespective of whether the final apparatus is intended for medical, industrial, scientific, or other applications.

Distinguishing this category from its sibling, 9022.90.15.00 (Radiation beam delivery units), is crucial. While this subheading focuses on the source of radiation, the sibling category pertains to the components that shape, focus, and direct that generated radiation beam towards its target. Therefore, a radiation generator unit produces the raw radiation, whereas a beam delivery unit manages and manipulates that radiation once it has been generated.

As this is a leaf node, there are no further subdivisions under 9022.90.05.00. Therefore, the classification hinges on accurately identifying the component as the primary source of radiation generation within a larger X-ray or ionizing radiation apparatus. Examples include the vacuum tube itself in an X-ray machine, or the radioactive isotope assembly in certain industrial gauging equipment, provided they are not specifically designed for beam manipulation and are instead solely responsible for the initial emission of radiation.
