HS Code 9018.13 – Medical, surgical instruments and appliances; magnetic resonance imaging apparatus
HS code 9018.13 is the 6-digit subheading for medical, surgical instruments and appliances, magnetic resonance imaging apparatus. It is used for 1.5 Tesla MRI systems, 3 Tesla MRI systems, open MRI scanners, wide-bore MRI machines and functional MRI (fMRI) systems.
What HS 9018.13 covers
This HS code specifically covers Magnetic Resonance Imaging (MRI) apparatus, which are advanced medical diagnostic tools that use powerful magnetic fields and radio waves to generate detailed images of organs, soft tissues, bone, and virtually all other internal body structures. MRI machines are critical for diagnosing a vast array of conditions, including neurological disorders, musculoskeletal injuries, and various cancers, offering unparalleled soft tissue contrast. The trade in MRI systems is driven by the increasing demand for high-resolution diagnostic imaging, technological innovation, and the expansion of specialized medical facilities globally. Importers and exporters include leading medical technology companies, large hospital networks, and government health departments. Key considerations involve magnetic field strength (e.g., 1.5T, 3T), patient comfort features, image acquisition speed, and strict adherence to international medical device regulations. These complex systems represent a significant investment in advanced healthcare infrastructure.

Top exporters and importers of HS code 901813, 2025
In 2025, the largest exporter of HS code 901813 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.

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).
