Import Tips
• Document stabilizer as <1% and solely for preservation; excess renders it a mixture under 3824.99
• Include polymerization inhibitor specification sheet matching industry standards for flavor chemical imports
• Segregate from oxidizing agents in shipping manifests to prevent reaction per IMDG Code
