Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If phenolic hydroxyl dominates without clear ether characterization
Simple phenols without prominent ether function classify earlier in Chapter 29 per numerical order rule (Note 3).
If when used/sold primarily as ketone-peroxide stabilizer
Specific functional use as 'oxygen function' compound may shift to later ketone derivative headings.
If imported as component in pesticide formulations
Herbicide/insecticide preparations containing these compounds classify under Chapter 38 goods.

Import Tips & Compliance
• Include NMR or GC-MS spectra verifying ether-phenol structure to distinguish from phenolic alcohols in heading 2907
• Label packages with stabilizer composition per Chapter Note 6(f); undisclosed additives may cause classification to mixtures in 3824
