Import Tips

• Verify chemical purity via Certificate of Analysis (CoA) to confirm it matches the exact named compound and meets Chapter 29 chemical definition requirements

• Include Safety Data Sheet (SDS) and ensure proper hazardous material labeling under DOT regulations for sulfonic acid compounds during import

• Avoid misclassification by confirming it's not a sulfonated derivative better suited for earlier Chapter 29 headings; consult CBP for rulings
