Import Tips
• Provide Certificate of Analysis (CoA) confirming purity >98% and chemical identity to avoid misclassification as mixtures
• Ensure SDS includes GHS hazard labeling for corrosive sulfonic acid properties; comply with TSCA registration for US entry
• Verify packaging prevents moisture absorption, as hygroscopic nature can affect duty assessment if contaminated
