Import Tips
• Provide certificates of analysis confirming anhydrous state (<0.1% water) to distinguish from hydrated forms
• Ensure proper UN packaging (4.1 flammable solids if pyrophoric) and DG declarations for hazardous material compliance
• Avoid bulk packaging contamination that could lead to reclassification as a mixture under 3824
