HS code for X-ray tubes: 9022.30
X-ray tubes.
Classification of X-ray tubes under HS 9022.30
X-ray tubes are classified under HS code 9022.30 because they are identified as specific components essential for the operation of apparatus based on the use of X-rays. According to the General Rules of Interpretation (GRI), products are classified based on their technical characteristics and their specific function within a broader system. Heading 9022 covers a wide range of X-ray equipment, including medical, surgical, dental, or veterinary apparatus, as well as industrial X-ray machines. However, subheading 9022.30 is reserved specifically for the tubes themselves. These are vacuum tubes designed to convert electrical input power into X-rays through the bombardment of a metal target with high-speed electrons. The classification applies to the tube as a standalone component, whether it is intended for diagnostic imaging, radiotherapy, or industrial non-destructive testing. It is important to note that the tube must be presented separately from the high-tension generator or the control panels to fall under this specific code; otherwise, the entire assembly might be classified as a complete X-ray apparatus.

Codes often confused with 9022.30
Common mistake. X-ray tubes are frequently misclassified under HS code 9022.14, which refers to other X-ray apparatus for medical, surgical, or dental use. The distinction lies in whether the item is a component (the tube) or the complete system (the machine). Additionally, they are sometimes confused with HS code 8540.89, which covers other thermionic, cold cathode, or photo-cathode valves and tubes. However, because X-ray tubes have a specific heading in Chapter 90, that chapter takes precedence over the general electrical components in Chapter 85.
Top exporters and importers of HS 902230 (the code used for X-ray tubes), 2025

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
