Import Tips
• Declare particle size and purity; powders may trigger additional dust explosion or inhalation risk assessments
• Comply with DOT hazardous material regulations for transport; label as UN1707 Thallium compounds (though pure metal)
• Check for REACH-like restrictions in destination markets due to thallium's environmental persistence
