Standard International Trade Classification
U.S. exports of Instruments & Apparatus for Measuring or Detecting Ionizing Radiation (SITC 87471) totaled $45.1M in August 2026.
Importers of Instruments & Apparatus 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 dataRadiation detection and measurement instruments — including Geiger counters, scintillation detectors, dosimeters, and survey meters — occupy a specialized niche at the intersection of nuclear safety, medical physics, and homeland security. Importers should be aware that certain radiation detection equipment may be subject to export-control review by the country of origin and import-licensing requirements under US Nuclear Regulatory Commission (NRC) frameworks, depending on the specific detector type and intended application. These instruments serve critical roles in nuclear power plant monitoring, medical imaging quality assurance, and environmental radiation surveillance programs.

Certain radiation detection instruments, particularly those incorporating radioactive check sources or designed for nuclear material safeguards, may require NRC licensing or coordination with the Department of Energy prior to import. Classification under SITC 87471 alone does not determine licensing status — the specific detector technology and intended end-use govern the regulatory pathway.
SITC 87471 covers instruments whose primary function is to measure or detect ionizing radiation emitted by an external source — think Geiger-Müller tubes, ionization chambers, and neutron detectors. Equipment that generates radiation as part of its own operation (such as diagnostic X-ray systems) is classified elsewhere in the SITC schedule.
