Import Tips & Compliance
• 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
