Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If compounds of thorium rather than uranium
Thorium fluorides are classified separately from uranium compounds in the preceding subheading.
If in the form of mixtures or residues rather than pure fluorides
Residues containing uranium fluorides fall under the broader mixtures and residues heading.
If the isotope mixture is enriched in U235 rather than depleted
Enriched uranium and its compounds are classified in Chapter 2845, distinct from depleted uranium products.

Import Tips & Compliance
• Obtain prior NRC authorization under 10 CFR Part 110 for export/import of uranium compounds; unlicensed import is prohibited
• Provide detailed radiation safety data, including specific activity levels, and ensure packaging meets UN 2977 standards for radioactive material
• Avoid misclassification by verifying depletion status (U235 <0.711%); full U235 assay reports prevent customs delays
