Import Tips
• Declare exact chemical composition and CAS number (1303-33-9) on commercial invoice to support HTS classification
• Comply with ITAR/EAR export controls if destined for optical/military end-use; obtain end-user certificates
• Use DOT-approved packaging for toxic substances; avoid common pitfall of under-declaring arsenic content leading to penalties
