Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If total impurities exceed 5% w/w
Technical grades failing chemical compound purity threshold classify as chemical mixtures.
If ester content dominates chemically
Partial esters present as impurities may trigger aldehyde/ketone classification if predominant.

Import Tips & Compliance
• Specify impurity profile (benzaldehyde <0.5%, cinnamaldehyde <1%) to justify pure compound status
• Large bulk shipments require proper ventilation certification per IMDG Code (UN 2811)
• Technical Data Sheet must confirm minimum 95% assay to avoid 3824 mixture classification
