HS code for MRI machine: 9018.13
Medical, surgical instruments and appliances, magnetic resonance imaging apparatus.
Classification of MRI machine under HS 9018.13
Magnetic Resonance Imaging (MRI) machines are classified under HS code 9018.13. This classification falls within Chapter 90, which covers optical, photographic, cinematographic, measuring, checking, precision, medical or surgical instruments and apparatus. Specifically, heading 9018 encompasses instruments and appliances used in medical, surgical, dental, or veterinary sciences. Subheading 9018.13 is specifically reserved for magnetic resonance imaging apparatus. The classification is determined by the primary function of the device, which is diagnostic medical imaging through the use of powerful magnetic fields and radio waves to generate detailed images of the internal structures of the body. Unlike X-ray equipment, MRI machines do not utilize ionizing radiation, which is a critical factor in distinguishing them from other imaging modalities within the Harmonized System. The apparatus typically includes the magnet, gradient coils, radiofrequency coils, and the computer system used for image reconstruction, all of which are treated as a functional unit under this code.

Codes often confused with 9018.13
Common mistake. MRI machines are frequently confused with HS code 9022.14 or 9022.19. However, heading 9022 is strictly for apparatus based on the use of X-rays or alpha, beta, or gamma radiations. Since MRI technology relies on magnetic resonance rather than ionizing radiation, it must be classified under 9018. Additionally, some importers mistakenly use 8543.70 for specialized electrical machines, but the specific medical diagnostic provision in 9018 takes precedence over general electrical headings.
Top exporters and importers of HS 901813 (the code used for MRI machine), 2025
In 2025, the largest exporter of HS 901813 (the code used for MRI machine) in UN Comtrade data was Germany, with 33% of world exports; the largest importer in UN Comtrade data was the United States, with 11% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 901813, not only MRI machine.

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).

Questions about MRI machine
What is the HS code for MRI machine?
The HS code for MRI machine is 901813 (Medical, surgical instruments and appliances; magnetic resonance imaging apparatus). The international HS code for a Magnetic Resonance Imaging (MRI) machine is 9018.13.
How do I classify MRI machine for customs?
MRI machine is classified under HS code 901813 — Medical, surgical instruments and appliances; magnetic resonance imaging apparatus. This is a 6-digit subheading level code.
Does this code include the cooling systems for the magnets?
If the cooling system (such as a cryostat or chiller) is imported as an integral part of the MRI system, it is classified under 9018.13. If imported separately, it may be classified under 8418 or 8419 depending on its design.
Which countries are the top exporters of MRI machine (HS 901813)?
In 2025, the top exporters of HS 901813 (the code used for MRI machine) in UN Comtrade data were Germany ($1.9B, 33% of world exports), China ($884M) and the Netherlands ($837M). World exports came to about $5.7B, 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.
Which countries are the top importers of MRI machine (HS 901813)?
