Import Tips
• Label shipments with UN 1609 hazardous code and ensure proper segregation from organic materials during transport
• Include assay reports proving >99% purity to maintain classification as chemically defined compound
• Check state-specific mercury import bans; federal TSCA pre-notification is mandatory for quantities over 1 kg
