HS code for Fish milt: 0302.91

Fish, fresh or chilled, livers, roes and milt.

Classification of fish milt under HS 0302.91

HS Code 030291 is the designated classification for fresh or chilled fish milt, as well as livers and roes. Milt is the seminal fluid of male fish and is consumed as a delicacy in several cultures, such as "shirako" in Japan. Within the Harmonized System, milt is grouped with roes and livers because they are all internal edible organs (offal) of the fish. The classification requires the product to be in a fresh or chilled state, meaning it has been kept at low temperatures to prevent spoilage but has not been frozen. This classification follows GRI 1, as the subheading text explicitly mentions milt. The trade of milt is highly seasonal and requires strict adherence to cold chain logistics to maintain the quality required for this specific HS code.

Codes often confused with 0302.91

Common mistake. Fish milt is frequently confused with fish roe (eggs), but while they share the same HS code (030291), they are biologically different. A more significant misclassification error involves the state of preservation; frozen milt must be classified under HS code 030391. If the milt is dried, salted, or smoked, it moves to heading 0305. Furthermore, if the milt is prepared or preserved (e.g., canned or seasoned), it is classified under HS code 1604.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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).
