U.S. imports of radioactive alloys, dispersions, isotopes & compounds (nes) (HS 284443) totaled $56.4M in April 2026, traded with 25 countries.
Importers of Radioactive Alloys, Dispersions, Isotopes & Compounds (NES) paid $74K in duties in April 2026 — an effective duty rate of 4.9% on $1.5M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataCobalt-60-bearing elements and other radioactive isotopes and compounds not elsewhere specified are among the most tightly regulated imports in US trade, requiring Nuclear Regulatory Commission licensing and strict transport compliance under DOT hazardous materials rules. The US tariff schedule breaks this heading into four 10-digit lines: Co-60 radioactivity articles (2844430010), general radioactive elements and isotopes NESOI (2844430020 and 2844430028), and alloys, dispersions, ceramic products, and mixtures (2844430050). Canada leads supply, with Germany and the Netherlands also significant sources, reflecting the concentration of isotope production and processing capacity in those countries. Importers must coordinate NRC import authorizations well in advance, as licensing timelines can affect shipment scheduling.

Importers generally must hold a valid Nuclear Regulatory Commission (NRC) specific license or qualify under a general license exemption. DOT hazardous materials regulations also govern packaging, labeling, and transport. Consult a licensed customs broker and NRC counsel before shipment.
The four 10-digit lines separate Co-60-specific articles (2844430010) from general radioactive elements and isotopes NESOI (2844430020 and 2844430028) and from alloys, dispersions, ceramic products, and mixtures (2844430050). Correct classification depends on the specific isotope, its activity level, and its physical form.
