Import Tips
• Verify chemical purity and provide Certificate of Analysis (COA) to confirm classification as a glycerol ether
• Ensure food-grade certifications (e.g
• FDA GRAS) if destined for food use to avoid reclassification
• Avoid common pitfall of mislabeling as a simple ester, which could shift to heading 2915
