Import Tips

• Provide detailed chemical analysis certificates confirming sulfur-carbon bond structure to verify Chapter 29 classification over Chapter 28 inorganic acids

• Include Safety Data Sheets (SDS) and end-use declarations, as cosmetic vs industrial applications may trigger different regulatory scrutiny

• Avoid misclassification as a simple thiol by documenting acid functionality; common pitfall is shipment without proper UN hazard labeling
