Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If already formulated into sterile injectable solution
Medicaments in measured doses for injection classified in Chapter 30 regardless of alkaloid content.
If primarily classified by sulfate/chloride ion content
Inorganic acid salts take precedence over organic base classification per note 3(C).
If anhydrous base form without hydrochloride salt
Free base quinine uses specific statistical breakout before 'other' category.
