Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as sodium salt rather than free sulfonic acid
Salts of sulfonic acids classified with parent acid, but different statistical suffix.
If sulfonation dominates over amine function
Chapter notes prioritize sulfonated derivatives in earlier headings if not compound derivative.
If diluted for safety transport exceeding Chapter 29 solvent limits
Excess solvent renders it a preparation under Chapter 38 rather than pure compound solution.

Import Tips & Compliance
• Provide titration data confirming sulfonic acid content and free acid form (not salt)
• Include stability data as sulfonic acids are prone to decomposition during transport
• Label clearly to distinguish from non-sulfonated toluidines avoiding misclassification
