Import Tips
• Provide certificates of analysis confirming chemical purity and phenothiazine structure to avoid reclassification
• Ensure FDA registration and drug master files are complete for pharmaceutical imports; common pitfall is missing impurity declarations
• Label shipments with exact CAS number (58-88-8) and batch details to facilitate customs clearance
