U.S. exports of X-Ray Tubes (SITC 77423) totaled $65.3M in August 2026.
Importers of X-Ray Tubes paid $3.0M in duties in August 2026, an average duty rate of 10.88% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataX-ray tubes are the core vacuum-tube components that generate X-radiation in diagnostic imaging, computed tomography, industrial inspection, and security screening systems. As components rather than finished apparatus, they are classified separately from complete X-ray machines and typically enter trade as replacement parts or OEM inputs for equipment manufacturers. FDA's Electronic Product Radiation Control program applies to X-ray tube assemblies, requiring manufacturers to file reports and certify compliance with applicable performance standards even for component-level imports. Lead times and specialized anode/cathode configurations (rotating vs. stationary anode, focal spot size) make sourcing decisions technically driven.

Yes. FDA's Electronic Product Radiation Control provisions apply to X-ray tube assemblies regardless of whether they are imported as standalone components or within a finished system. Manufacturers and importers must file accession reports and certify that the tubes meet applicable performance standards under 21 CFR Subchapter J.
Key specifications include anode type (rotating vs. stationary), focal spot size, peak kilovoltage rating, and heat capacity. CT applications demand high-capacity rotating-anode tubes with small focal spots, while dental and portable units use lower-power stationary designs. These differences affect both the applicable product standard and the pool of qualified suppliers.
