HS code for Marine mammal oil: 1504.30
Fats and oils and their fractions, of marine mammals.
Classification of marine mammal oil under HS 1504.30
Marine mammal oil falls under HS code 1504.30, which covers fats and oils and their fractions of marine mammals, whether or not refined, but not chemically modified. This classification is part of Chapter 15, which encompasses animal or vegetable fats and oils and their cleavage products. Heading 15.04 is specifically for fats and oils and their fractions of fish or marine mammals. While subheadings 1504.10 and 1504.20 cover fish-liver oils and other fish oils respectively, 1504.30 is reserved for oils derived from mammals such as whales, dolphins, seals, and walruses. The classification remains here regardless of whether the oil is crude or refined, provided it has not undergone chemical modification like hydrogenation or esterification. The determination of this code relies entirely on the biological origin of the oil. Importers must provide certification of the source species to ensure correct classification, especially given the international regulations surrounding trade in products derived from marine mammals, such as the CITES treaty. The oil must be primarily composed of triglycerides and must not have been processed into a specific food preparation or industrial chemical that would move it to a different chapter. Fractions of these oils, obtained by chilling or solvent extraction, are also included here as long as they retain the character of marine mammal oil.

Codes often confused with 1504.30
Common mistake. Marine mammal oil is often confused with fish-liver oils (HS code 1504.10) or other fish oils (HS code 1504.20). Additionally, if the oil has been hydrogenated or solidified through chemical processes, it must be classified under HS code 1516.10 as an animal fat that has undergone chemical transformation.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
