Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If derived from marine microorganisms misclassified as fish
Hierarchy may place marine-derived in fish oils if not proven microbial.
If sold as aquafeed ingredient mix
Set with carriers becomes prepared animal feed under 2309.
If merely denatured without hydrogenation
Chapter note routes denatured oils to 1518.

Import Tips & Compliance
• Aquaculture importers need Aphis permits if for animal feed; specify end use
• Validate microbial vs marine origin to avoid 1504 fish oil heading
• Bulk drums only; retail packaging risks 21xx reclassification
