Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If when part of wood tar creosote mixture
Creosote oils from wood tar distillation are specifically covered in Chapter 38, excluding Chapter 29 coverage.
If not explicitly recognized as primary guaiacol derivative
Other ether-phenol derivatives not specified under guaiacol subheading go to residual category.
If imported as odoriferous substance for perfumery
Chapter excludes odoriferous additions rendering product suitable for specific perfumery use.

Import Tips & Compliance
• Submit GC-MS analysis proving >95% purity as 4-methyl-2-methoxyphenol to distinguish from creosote mixtures
• Avoid retail packaging that might trigger reclassification as consumer chemical preparation under Chapter 38
• Declare CAS 93-51-6 explicitly; ensure no anti-dusting agents added beyond chapter note g allowances
