Import Tips
• Verify purity levels and provide chemical analysis certificates to confirm classification under Chapter 29 as a separate chemically defined organic compound
• Include Safety Data Sheets (SDS) and ensure proper hazardous material labeling for transport as it is corrosive
• Avoid misclassification as mixtures; single isomer products stay in 2929 while blends may shift to Chapter 38
