Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If considered aromatic monoamine salt not specifically toluidine-derived
General toluidine salts without specific naming fall under broader toluidine subheading.
If hydrochloride content dominates as inorganic chloride compound
High inorganic salt content could shift classification from organic compound salt per Chapter 29 note 1(C).
If for industrial end-use in heterocyclic compound synthesis
End-use as intermediate for Chapter 29 heterocyclics may trigger reclassification if not pure chemical.

Import Tips & Compliance
• Submit salt formation analysis and pH verification to confirm hydrochloride status without excess inorganic content
• Ensure packaging prevents moisture absorption, as deliquescence could affect purity declarations
