U.S. imports of magnetic resonance imaging (mri) apparatus (HS 901813) totaled $31.7M in April 2026, traded with 15 countries.
Importers of Magnetic Resonance Imaging (MRI) Apparatus paid $3.2M in duties in April 2026 — an effective duty rate of 10% on $31.4M in dutiable value, based on actual customs collections rather than the published tariff schedule. Magnetic Resonance Imaging (MRI) Apparatus imports of $31.7M in April 2026 ran 25% below the year-to-date monthly average of $42.1M.
Last updated: April 2026 dataMRI systems are among the highest-value capital medical devices traded internationally, classified under a single tariff line (9018130000) and regulated by FDA CDRH as Class II or Class III devices requiring premarket clearance or approval. Germany and Japan are the leading suppliers to the US market, reflecting the concentration of major OEM manufacturing among a handful of European and Asian multinationals. Field strength (measured in Tesla), bore configuration, and intended clinical application (whole-body, extremity, interventional) are the primary specification distinctions relevant to both procurement and regulatory classification. Given the complexity of MRI system components — including superconducting magnets, gradient coils, and RF subsystems — importers frequently encounter questions about whether subassemblies classify separately or as parts of the complete apparatus.

Classification depends on whether the component is imported as a complete or incomplete machine versus a dedicated part. Complete or functionally assembled MRI systems generally classify under 9018130000, while dedicated parts may fall under the parts provisions of Chapter 90. The distinction requires analysis of GRI rules and relevant chapter notes; a licensed customs broker should be consulted for specific component classifications.
The global MRI market is concentrated among a small number of large OEMs — primarily headquartered in Germany and Japan — that control proprietary superconducting magnet and gradient coil technology. This manufacturing concentration means the US import supply base is inherently narrow, creating potential lead-time and sourcing risks for hospital procurement teams.
