Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified primarily by nitro function over hydrazine
Chapter note clarifies nitro groups aren't 'nitrogen functions' for 2929, but misemphasis could lead to o-/m-/p-nitroaniline-like classification.
If sulfur atom directly linked to carbon
Organo-sulfur compounds in 2930 take precedence if sulfur defines character over hydrazine.
If put up as fluorescent brightener
Chapter exclusion (g) moves synthetic organic luminophores to Chapter 32.

Import Tips & Compliance
• 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
