Import Tips
• Obtain DEA or BIS export licenses if end-use involves scheduled chemicals; common pitfall is incomplete Schedule 1 declarations
• Test for halide content to confirm dihalide status; monohalides shift to other nitrogen functions
• Use bulk stainless steel containers to prevent reaction with packaging materials
