Import Tips
• Validate HCl content (typically 18-21%); excess free acid causes eye irritation compliance issues
• Use amber packaging for light-sensitive imports; UV degradation affects potency declarations
• Distinguish research vs GMP grades; non-GMP may face FDA detention without end-use certificates
