HS Code 90.22 – Apparatus based on the use of x-rays or of alpha, beta, gamma or other ionising radiations, whether or not for medical, surgical, dental or veterinary uses, including radiography or radiotherapy apparatus, x-ray tubes and other x-ray generators, high tens

HS code 9022 is a 4-digit heading in the Harmonized System that covers: Apparatus based on the use of x-rays or of alpha, beta, gamma or other ionising radiations, whether or not for medical, surgical, dental or veterinary uses, including radiography or radiotherapy apparatus, x-ray tubes and other x-ray generators, high tens. Heading 9022 is a pivotal classification in international trade, encompassing a sophisticated array of apparatus based on the use of X-rays or other ionizing radiations. This includes equipment for medical, surgical, dental, and veterinary applications, as well as industrial, scientific, and security uses. The scope is exceptionally broad, covering diagnostic imaging systems like radiography apparatus and CT scanners, therapeutic devices such as radiotherapy linear accelerators and gamma knife systems, and industrial inspection equipment for non-destructive testing. It also includes essential components like X-ray tubes, high-tension generators, and control panels. The 'whether or not for medical, surgical, dental or veterinary uses' clause significantly expands its reach beyond healthcare into sectors like aerospace, automotive, security screening (e.g., baggage scanners), and materials science (e.g., X-ray diffraction). Proper classification under 9022 is paramount for trade compliance due to the high value, technological complexity, and often dual-use nature of these goods. They are subject to stringent regulatory controls, export licensing requirements in many jurisdictions, and varying tariff rates. Historically, the advent of X-ray technology revolutionized diagnostics and material analysis, and this heading reflects the continuous innovation in this critical field. As part of Chapter 90, which covers precision and medical instruments, it underscores the technical precision and specialized application of these indispensable tools. Misclassification can lead to severe penalties, extended customs delays, and non-compliance with international health, safety, and export control regulations, making expert classification essential.

Traders often confuse 9022 with other medical or scientific instruments. For instance, **9018** (Instruments and appliances for medical, surgical, dental or veterinary sciences, not specifically mentioned elsewhere) is a common misclassification, especially for medical devices that *don't* use ionizing radiation, such as ultrasound machines or MRI scanners. The key distinction for 9022 is the explicit use of 'x-rays or alpha, beta, gamma or other ionising radiations.' Another error might be classifying specific parts, like X-ray tubes, under **9033** (Parts and accessories not specified or included elsewhere in this Chapter) when they are explicitly mentioned and belong to 9022. Finally, **9027** (Instruments and apparatus for physical or chemical analysis) might be mistakenly used for analytical X-ray equipment, but if it generates X-rays for analysis, 9022 is generally more specific.

In 2025, the top exporters of HS code 9022 in UN Comtrade data were Germany ($6.2B, 22% of world exports), the United States ($3.9B) and the Netherlands ($3.3B). World exports came to about $27.7B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 9022 in UN Comtrade data were the United States ($4.8B, 17% of world imports), China ($3.5B) and Germany ($1.6B). World imports came to about $29.0B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 9022 is a 4-digit heading under Chapter 90 of the Harmonized System. The first 2 digits (90) identify the chapter, and digits 3-4 (22) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
