Import Tips
• Provide FDA Drug Master File reference and COA showing >99% purity to prevent reclassification as mixtures
• Declare as 'chemically defined compound' explicitly; avoid generic 'chemical' descriptions that trigger additional scrutiny
• Comply with TSCA import certification; watch for REACH compliance if transshipping from EU
