Last updated: July 2026 dataRadioactive residues — byproducts and waste streams generated from nuclear fuel processing, isotope production, or reactor operations — enter US commerce under a single 10-digit line (2844440000) and are subject to NRC import licensing requirements alongside strict DOT transport rules for radioactive materials. Canada is the leading supplier, with Japan and the Czech Republic also notable sources, reflecting the geographic distribution of nuclear fuel cycle infrastructure. Classification here turns on whether the material is a residue or byproduct rather than a refined compound or alloy; misclassification between this heading and adjacent radioactive compound headings is a common audit issue.

Radioactive residues are waste or byproduct streams from nuclear processes — not chemically defined or intentionally produced compounds. If a material has been further processed into a defined chemical compound or alloy, it likely falls under a different subheading in Chapter 28. A licensed customs broker with nuclear materials experience should review the material's technical data sheet before entry.
Yes. Beyond standard CBP entry, shipments typically require advance NRC import authorization and must comply with DOT 49 CFR hazardous materials regulations governing radioactive cargo, including Type A or Type B packaging depending on activity levels. Coordination with the port health and safety officer may also be required.
