Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If derived from halibut specifically
Only halibut-liver oils get the dedicated 1504.10.20.00; pollock as 'other' fish liver goes to 1504.10.40.00.
If blended with vegetable oils
Mixtures of fish liver oils with vegetable fats fall under 1512 for fixed vegetable fat mixtures, not pure fish-liver fractions.
If it's soap-stocks or residues from processing
Per chapter notes, processing residues like soap-stocks from fish-liver oil production classify in 1522, not the primary oil.

• Avoid common pitfalls like mislabeling as 'fish oil' generically, which could lead to scrutiny over liver-specific classification
