Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If statistically reported separately as principal quinidine
Customs may breakout major commercial alkaloids from 'other' category.
If nitrogen-function without full cinchona recognition
Compounds with 'nitrogen-function' classified heading 2929 per notes.
If anti-freeze preparation containing quinine
Specified industrial preparations classified heading 3820.
