Import Tips
• Document stabilizer percentage (<0.1% typical) to confirm it qualifies as 'necessary for preservation' under Chapter 29 note (f)
• Label as UN 1088 (stabilized) and provide stabilization certificate to differentiate from unstabilized forms
• Avoid retail packaging over 1L to prevent scrutiny under Chapter 29 exclusions for consumer preparations
