1504.10 - Fish-liver oils and their fractions:

This HTS category, 1504.10, specifically encompasses fish-liver oils and any fractions derived from them. These are distinct oils obtained from the livers of fish, which are often rich in essential nutrients and fatty acids like Omega-3. The classification focuses solely on these liver-derived oils, irrespective of whether they have undergone refining processes, as long as they have not been chemically modified.

It is crucial to differentiate 1504.10 from its sibling categories. Unlike 1504.20, which covers fats and oils derived from fish other than their livers, or 1504.30.00.00, which pertains to fats and oils from marine mammals, this category is exclusively for oils originating from fish livers. The source of the oil (liver versus other fish parts or marine mammals) is the primary distinguishing factor at this level.

Within the 1504.10 category, further subdivisions are made to provide more granular classification. The subcategories 1504.10.20.00 and 1504.10.40.00 distinguish between specific types of fish-liver oil, such as cod-liver oil, and other fish-liver oils not otherwise specified. This detailed breakdown aids in accurately identifying the precise commodity for trade and regulatory purposes.
