9022.90.40.00 - Of X-ray tubes

This HTS category, 9022.90.40.00, specifically covers parts and accessories for apparatus that generate or utilize X-rays, as well as other ionizing radiations. This includes components and supplementary items for radiography, radiotherapy, and other medical, surgical, dental, or veterinary applications involving such technologies. Examples of goods that would fall under this classification include replacement X-ray tubes, high-tension generators, control panels, screens, examination tables, and chairs designed for use with X-ray equipment.

At this level, this category is distinguished from its sibling "Other" (9022.90.80.00) by its explicit focus on parts and accessories *of X-ray tubes*. While the sibling category would encompass other miscellaneous parts and accessories for X-ray apparatus not specifically enumerated or otherwise classified, this node is dedicated to items directly related to or integral to the functioning of the X-ray tube itself or its immediate supporting electrical components.

As this is a leaf node, there are no further subcategories. Classification under 9022.90.40.00 is determined by the item's essential character and its direct relationship to X-ray generation or emission systems within the broader scope of X-ray apparatus outlined in heading 9022.
