Import Tips
• Declare intended use (flavor vs pharmaceutical) on entry documents as this affects potential FDA oversight
• Provide GC-MS analysis verifying structure and isomer purity to distinguish from 2- or 5-methylthiazole isomers
• Ship in amber glass bottles to prevent light-induced degradation, with COA included in shipment
