HS code for X-ray generators: 9022.90

Apparatus based on use of x-rays and similar, parts and accessories (x-ray generators, tubes, high tension generators, control panels and desks, screens, examination or treatment tables, chairs and like.

Classification of X-ray generators under HS 9022.90

X-ray generators are classified under HS code 9022.90. This classification is part of Chapter 90, which encompasses optical, photographic, cinematographic, measuring, checking, precision, medical or surgical instruments and apparatus. Heading 9022 specifically covers apparatus based on the use of X-rays or alpha, beta, or gamma radiations. While complete X-ray systems are classified in the earlier subheadings of 9022, subheading 9022.90 is reserved for "Other, including parts and accessories." X-ray generators are the high-voltage power supplies that provide the necessary electrical energy to the X-ray tube to produce radiation. Because they are essential components designed specifically for X-ray apparatus, they are classified as parts/accessories under 9022.90 rather than as general electrical transformers or generators in Chapter 85.

Codes often confused with 9022.90

Common mistake. X-ray generators are often misclassified under HS code 8504.40 (static converters) or 8501 (electric motors and generators). However, because these generators are specialized for X-ray production, Note 2(b) to Chapter 90 dictates they must be classified under 9022. Another common confusion is with X-ray tubes, which have their own specific subheading, 9022.30. Complete CT scanners should be classified under 9022.12.

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).
