Import Tips
• Provide pharmacopeial compliance docs (USP/EP certificate) and stability data for ester integrity during shipping
• Avoid wooden pallets; use temperature-controlled containers to prevent palmitate hydrolysis above 30°C
• Declare exact ester content; mislabeling as base form triggers reclassification to Chapter 30 medicaments
