Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing other oxygen functions beyond simple ketone-alcohol
More complex ketone-alcohols or derivatives fall under the residual provision in the same heading.
If imported as a formulated mixture with >70% solvent content
Mixtures of organic solvents not chemically defined as single compounds classify in Chapter 38 as chemical preparations.
If acyclic alcohol content predominates over ketone function
Classification prioritizes principal function; pure alcohols without significant ketone properties go to heading 2905.
