Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

2921.43Same rate: 43.3%

If imported as sodium salt rather than free sulfonic acid

Salts of sulfonic acids classified with parent acid, but different statistical suffix.

2904.10.37.00Lower: 43% vs 43.3%

If sulfonation dominates over amine function

Chapter notes prioritize sulfonated derivatives in earlier headings if not compound derivative.

3824.99.39Lower: 37.5% vs 43.3%

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
