Import Tips
• Document stabilizer as 'necessary for preservation/transport' per note (f) with <1% concentration to maintain pure compound status
• Conduct stability testing if challenged by customs on whether additions render it suitable for specific use
• Use stainless steel drums compatible with epoxide reactivity to prevent polymerization during transit
