Import Tips
• 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
