Import Tips
• Verify purity certificates (USP grade) and provide chemical analysis to confirm cyclic polymer structure per Chapter 29 notes
• Include Safety Data Sheets (SDS) showing sedative/hypnotic use to avoid misclassification as industrial solvents
• Ensure proper HazMat shipping declarations as it's a flammable liquid (UN 2606)
