Import Tips

• Purity certificate (HPLC) showing >95% named compound essential; lower purity risks reclassification as 3824 mixture

• Declare as 'chemical intermediate' not 'active pharmaceutical ingredient' to avoid Chapter 30 scrutiny

• Hazardous material shipping papers required (UN number if applicable); DOT classification impacts transport costs
