Saxitoxin with Stabilizer
Saxitoxin with stabilizer is a chemically defined alkaloid toxin, naturally produced by certain marine dinoflagellates, to which a stabilizer has been added solely to ensure preservation during transport and storage. Under Chapter 29, the addition of a stabilizer necessary for preservation does not alter its classification as an alkaloid, and it is therefore classified under tariff item 2939.80.00 as an 'other' alkaloid.
