Last updated: August 2026 dataMRI systems are among the highest-value medical devices traded under Chapter 90, and the US market relies heavily on imports from Germany, Japan, and the Netherlands—home to the world's leading MRI manufacturers. All imported MRI apparatus must comply with FDA 510(k) clearance or premarket approval requirements before commercial distribution, and the importer of record bears responsibility for ensuring the device is properly registered with FDA prior to entry. Classification under the single 10-digit line 9018130000 is generally straightforward, but trade professionals should confirm that system components imported separately (coils, gradient amplifiers, cryostats) are correctly classified under their own applicable headings rather than bundled under this code.

108 import shipments a month
MRI systems are Class II or Class III medical devices regulated by FDA's Center for Devices and Radiological Health (CDRH). The device must have received 510(k) clearance or premarket approval before it can be commercially distributed. At entry, FDA may detain shipments for review, and the importer must be able to demonstrate the device's regulatory status. Radiation-emitting electronic products also require compliance with FDA performance standards under the Electronic Product Radiation Control provisions.
Complete MRI systems are classified under 9018130000, but separately imported components—such as radiofrequency coils, gradient subsystems, or superconducting magnet assemblies—may fall under different HTS headings depending on their essential character and function. Importers should obtain a binding ruling from CBP or work with a licensed customs broker to confirm the correct classification for each component, as misclassification can result in duty underpayment and penalties.
