Import Tips

• Obtain NRC or agreement state license prior to import due to thorium's radioactive nature; submit Form 741 for reporting

• Include detailed chemical composition, activity levels, and safety data sheets in documentation to avoid customs delays

• Verify exemption status for low-specific-activity thorium; common pitfall is failing radiation transport regulations under DOT
