Import Tips

Verify purity and ensure the product contains only sulfo groups without additional functional groups that would shift classification

Provide detailed chemical analysis certificates confirming aromatic hydrocarbon sulfonation to avoid misclassification as mixtures

Check for stabilizer additions; if exceeding safety/transport limits, may fall under different provisions
