Import Tips
• Provide spectroscopic confirmation (NMR/IR) of nitro substitution to affirm chemically defined status
• Classify as UN 3294 toxic solid; use child-resistant packaging for retail lab quantities
• Avoid declaring as 'nitro compound' primarily, as hydrazine parent takes precedence in 2928
