Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primary product is its dehydrated derivative
Derivatives like butanone take precedence over parent alcohols per chapter classification rules.
If imported as nitrocellulose lacquer solvent component
Mixtures prepared for specific solvent applications classified as chemical preparations.
If acyclic with six or more carbon atoms
Longer chain acyclic alcohols fall under subsequent numerical headings.

Import Tips & Compliance
• Submit optical rotation data to distinguish from racemic mixtures that might affect classification
• Include stabilizer declarations (e.g
• 0.01% MEHQ) to comply with chapter note (f) on added preservatives
• Avoid bulk shipments over 190 proof; concentrated solutions may trigger alcohol and tobacco tax scrutiny
