Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing additional substituents beyond the core quinuclidine structure
Other pyridine ring compounds with nitrogen hetero-atoms fall under the residual 2933.39 category.
If imported as a salt form, such as 3-quinuclidinol hydrochloride
Organic salts are classified under heading 2942 per Chapter 29 note on salts of organic compounds.
If dissolved in solvent for safe transport rather than general use
Solutions of Chapter 29 compounds for transport fall under mixtures per Chapter note (e).
