Importers of Electromagnets, Magnetic Holding Devices & Parts paid $5.9M in duties in August 2026, an average duty rate of 11.94% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Electromagnets, Magnetic Holding Devices & Parts imports of $52.9M in August 2026 ran 24% above the year-to-date monthly average of $42.7M.
Last updated: August 2026 dataElectromagnets for MRI apparatus (8505907000) represent the highest-value segment of this heading, serving the medical imaging sector with superconducting coil assemblies that require specialized handling and regulatory awareness distinct from industrial lifting or workholding applications. Electromagnetic lifting heads (8505903000) and workholders (8505904000) serve heavy manufacturing and metalworking operations. Mexico leads US import supply across the heading, with China and Germany also significant sources. Importers of MRI electromagnets should note that while the magnets themselves are classified here rather than under heading 9018, the broader MRI system may trigger FDA device registration requirements depending on how the shipment is presented.

The HTS schedule specifically provides for electromagnets for MRI apparatus under 8505907000, with the parenthetical 'other than 9018' confirming that these components are excluded from the medical instruments heading. The classification reflects that the electromagnet is an electromechanical component rather than a complete medical instrument. Importers should ensure the commercial invoice and entry documents describe the article as an MRI electromagnet component to avoid misclassification under 9018.
Both electromagnetic and permanent magnet chucks and workholders fall within heading 850590, but at the 10-digit level, 8505904000 specifically covers electromagnetic workholders and their parts. Permanent magnet chucks and clamps are also within the heading's scope but classified under the NESOI lines. The actuation method — electromagnetic coil versus fixed permanent magnet — is the distinguishing criterion, and technical specifications should be retained to support the claimed line.
