SITCSection 7
U.S. imports of particle accelerators (SITC 77871) totaled $3.1M in April 2026, traded with 14 countries.
Importers of Particle Accelerators paid $363K in duties in April 2026 — an effective duty rate of 14% on $2.5M in dutiable value, based on actual customs collections rather than the published tariff schedule. Particle Accelerators imports of $3.1M in April 2026 ran 26% below the year-to-date monthly average of $4.1M.
Last updated: April 2026 dataCyclotrons, synchrotrons, linear accelerators, and related particle-beam machines are among the most capital-intensive and technically specialized imports in the electrical machinery category, used primarily in medical isotope production, cancer radiotherapy, and high-energy physics research. Because many accelerator configurations involve dual-use technology with potential nuclear or defense applications, export controls in the country of origin and US import licensing requirements under relevant regulatory frameworks may apply. The small number of global manufacturers and the bespoke engineering involved mean each transaction is typically negotiated individually rather than traded as a commodity.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Certain particle accelerator configurations — particularly those capable of producing fissile material or with military applications — may be subject to dual-use export controls in the country of origin and could require coordination with US agencies such as the Department of Energy or the Nuclear Regulatory Commission upon import. Importers should conduct an end-use review and consult with a licensed customs broker or trade counsel before completing entry.
Both medical cyclotrons and research accelerators fall under this SITC heading, but at the HTS level the distinction between types (e.g., cyclotrons vs. synchrotrons vs. linear accelerators) and their rated beam energy may affect the applicable subheading. Importers should provide full technical specifications — including particle type, maximum energy, and intended end use — to support correct classification.
