Import Tips
• Provide elemental analysis confirming >99.9% lanthanum with trace elements only to maintain pure metal status
• Declare as pyrophoric solid (Division 4.2) for transportation; use nitrogen-purged packaging
• Document form factor (rods vs. powder) clearly to prevent confusion with manufactured articles
