U.S. imports of particle accelerators (HS 854310) totaled $13.6M in August 2026, imported from 17 countries.
Importers of Particle Accelerators paid $150K in duties in August 2026, an effective tariff rate of 1.10% of the $13.6M imported — duty actually collected as a share of that value, not the published tariff schedule. Particle Accelerators imports of $13.6M in August 2026 ran 159% above the year-to-date monthly average of $5.2M.
Last updated: August 2026 dataParticle accelerators — including cyclotrons, synchrotrons, linear accelerators, and betatrons — are capital-intensive scientific and industrial instruments classified under a single 10-digit line (8543100000). Belgium and Sweden are the leading US suppliers, reflecting European dominance in medical cyclotron manufacturing for radiopharmaceutical production; Canada and Germany are also significant sources. Medical cyclotrons used to produce PET radioisotopes represent the most commercially active import segment, while research accelerators for physics laboratories and industrial accelerators for materials processing or sterilization constitute additional trade flows. Import of accelerators intended for medical isotope production may involve coordination with the NRC and FDA depending on the downstream radiopharmaceutical application.

A medical cyclotron itself is a machine and clears CBP as an industrial import under 8543100000, but its downstream use in producing radioactive drugs triggers FDA oversight of the radiopharmaceuticals and potentially NRC licensing of the facility. Importers should confirm that the installation site holds appropriate NRC or Agreement State radioactive materials licenses before the accelerator arrives, as facility readiness affects commissioning timelines. Coordination with the equipment manufacturer on site acceptance testing and regulatory documentation is standard practice.
Yes. High-energy particle accelerators can be controlled under the Export Administration Regulations as dual-use items, particularly those capable of producing neutrons or isotopes with potential weapons-related applications. Importers who subsequently plan to re-export, transfer, or modify an accelerator should review the EAR ECCN classification of the specific equipment and consult with export-control counsel before any transfer, even within the US to a foreign national.
