U.S. exports of Instruments for Measuring or Detecting Ionizing Radiation (HS 903010) totaled $45.1M in August 2026.
Importers of Instruments for Measuring or Detecting Ionizing Radiation paid $1.8M in duties in August 2026, an average duty rate of 9.40% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataGeiger counters, scintillation detectors, dosimeters, and related apparatus for measuring or detecting ionizing radiation enter under a single tariff line (9030100000) and serve nuclear power, medical physics, environmental monitoring, and defense applications. Germany leads US import supply, followed by Finland, the United Kingdom, Canada, and France — a supplier base concentrated in countries with advanced nuclear and scientific instrumentation industries. Importers should be aware that certain radiation detection equipment may require export licenses from the supplier country and, depending on end-use, may be subject to US Nuclear Regulatory Commission (NRC) or Department of Energy oversight upon entry.

574 import shipments a month
The NRC's import jurisdiction primarily covers radioactive materials and nuclear equipment that contains radioactive sources. Passive detection instruments (e.g., Geiger counters, scintillation detectors without radioactive sources) generally do not require NRC import authorization, but instruments containing sealed radioactive check sources may require an NRC license. Importers should confirm the regulatory status of any source-containing component before shipment.
Germany, Finland, and the UK have long-established nuclear instrumentation industries supported by domestic nuclear power programs and defense research. Companies in these countries have developed specialized expertise in detector materials (e.g., high-purity germanium, scintillator crystals) and precision electronics that meet the stringent accuracy and reliability standards required for nuclear safety and medical physics applications, giving them a durable competitive advantage in the US market.
