HS heading 0308 covers aquatic invertebrates other than crustaceans and molluscs, such as sea cucumbers and sea urchins, in live, fresh, frozen, dried, salted or smoked form. Demand is concentrated in East Asia: in 2025, Japan, Hong Kong and China were the three largest importers in UN Comtrade data. For a company exporting from Spain, the choice of subheading and market sets the tariff and the requirements.

What to know before exporting heading 0308 from Spain
Heading 0308 sits in Chapter 03 of the Harmonized System and has eight subheadings. The heading groups products by the state in which they are traded: live, fresh or chilled, frozen, dried, salted, in brine or smoked. The state of the product decides the subheading, so classify each product before looking up any other requirement.
Import demand is concentrated in a few markets. In the table above, Japan, Hong Kong SAR China and China lead the ranking, and Macao, South Korea and Singapore follow. Together they show that the main buyers are in East and Southeast Asia, with the United States, Italy, France, Germany and Poland as the main destinations outside Asia.
For a company exporting from Spain, the tariff depends on the subheading, the destination and the trade agreement in force between the European Union and that country. The applicable duty can be checked by product and destination in Access2Markets. Within the EU single market, goods circulate without customs duties, so the tariff question only applies to non-EU destinations.
Sanitary and import requirements for aquatic products are set by each destination country, and they differ between live, frozen and dried products. They usually include health certification and registration of the establishment. Check the exact list with the destination's competent authority and with the Spanish export certification services before quoting a price.
Keep in mind that the import figures reflect what each country declares as imports from the world. They show where demand is, not what Spain can sell there, and they do not show the origin of the supply. Countries report with a delay, so the latest consolidated year is 2025.

Frequently asked questions
What products fall under HS heading 0308?
Heading 0308 covers aquatic invertebrates other than crustaceans and molluscs, whether live, fresh, chilled, frozen, dried, salted or in brine. It also covers smoked aquatic invertebrates of that kind, cooked or not before or during smoking. It has eight subheadings, and the exact product and its state determine which one applies.
Which countries import the most under heading 0308?
In UN Comtrade data for 2025, the largest importers were Japan, Hong Kong SAR China and China. They were followed by the United States, Macao SAR China and South Korea. Figures are imports declared by each country from the world, not exports from Spain.
How do I find the tariff for 0308 in a non-EU market?
The tariff depends on the subheading, the destination country and the agreement between the EU and that country. A company exporting from Spain can check the duty by product and market in Access2Markets, the European Commission's tool for market access information.
Do I pay customs duties when shipping 0308 products to another EU country?
No customs duties apply to goods moving between EU member states, because they circulate within the single market. Duties are relevant only for destinations outside the EU, such as Japan, China or the United States. Sanitary rules for aquatic products still apply within the EU.
Does the import volume of a country mean it is easy to enter?
No. Import volume shows the size of demand, not the ease of access. Access depends on the destination's sanitary requirements, tariff and trade agreements, which are set per country and per subheading and must be checked separately.
