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
