HS HEADING 1504

Fats and oils and their fractions of fish or marine mammals; whether or not refined, but not chemically modified

In plain English

This category covers fats and oils derived from fish or marine mammals, including their separated parts. These products are included regardless of whether they have been refined, provided they have not undergone chemical modification. The classification distinguishes between fish oils, specifically including liver oils, and other fish fats and oils that exclude liver varieties. It also separately lists fats and oils obtained from marine mammals.
