Import Tips
• Provide detailed chemical analysis and purity certificates to confirm classification under Chapter 29 as a separate chemically defined compound
• Ensure SDS (Safety Data Sheets) accompany shipments due to toxicity and flammability; verify compliance with TSCA registration
• Avoid misclassification as aromatic hydrocarbons (Chapter 29 heading 2902) by documenting the thiol functional group
