Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If from halibut livers
Halibut-liver oils have a specific statistical breakout in 1504.10.20.00, while other fish-liver oils default to the 'other' subheading.
If from general fish body, not specifically livers
Fats and oils from fish bodies (excluding livers) shift to 1504.20, as liver oils are distinctly separated in 1504.10.
If chemically modified, such as hydrogenated
Chemical modification like hydrogenation moves it out of 1504 to Chapter 15 headings for animal/vegetable fats that are chemically modified.

Import Tips & Compliance
• Verify the oil is from fish livers and not chemically modified (e.g

• Provide Certificates of Analysis (COA) confirming refinement process and absence of chemical modification, plus origin documentation for fish species
• Label accurately with nutritional content, especially omega-3 levels, to comply with FDA import requirements and avoid holds at customs
