Import Tips
• Provide Certificate of Analysis confirming >98% purity and absence of isomers to avoid reclassification under mixtures note (b)
• Ensure USP/EP pharmacopeia compliance for FDA import; common pitfall is missing stability data for anhydrous form
• Declare exact caffeine content per kg; anti-dumping duties may apply from certain origins
