Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If when put up in retail packaging with dilution for perfumery
Mixtures containing odoriferous ether-phenols prepared as retail perfume products fall under Chapter 33 rather than pure Chapter 29 compounds.
If classified primarily by alcohol function over ether-phenol
Per Chapter 29 note on oxygen functions, compounds with competing alcohol groups may classify under later numerical headings like 2916 for cyclanic alcohols.

Import Tips & Compliance
• Verify purity and chemical identity via Certificate of Analysis to confirm classification as chemically defined ether-phenol under Chapter 29 note (a)
• Include Safety Data Sheets (SDS) documenting odoriferous use to distinguish from medicinal applications potentially reclassified elsewhere
• Avoid common pitfalls by ensuring no added solvents render it suitable for specific non-general use per Chapter 29 note (e)
