Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily lysergic acid derivative
Lysergic acid and its salts have specific heading 2939.41, taking precedence over general ergot derivatives.
If when imported as finished migraine tablets
Finished pharmaceutical dosage forms fall under Chapter 30, not bulk chemical substances.
If chemical analysis shows not rye ergot origin
Other vegetable alkaloids go to 2939.99; chapter notes require specific rye ergot identification.

Import Tips & Compliance
• Verify purity and obtain FDA import permit as it's a controlled pharmaceutical substance
• Include Certificate of Analysis confirming it's a rye ergot derivative, not LSD precursor
• Avoid misclassification as general pharmaceuticals (Chapter 30) by providing chemical structure documentation
