Fish, Prepared or Preserved (NESOI)

Thailand, India, and Japan are the leading foreign suppliers of prepared and preserved fish under this residual heading, which captures a wide range of value-added products — fish pastes, fish balls, cakes, puddings, breaded fish sticks, and mixed seafood meal preparations — that do not fall under more specific headings. The US tariff schedule subdivides the heading into more than a dozen 10-digit lines, distinguishing products by form (paste vs. formed product), oil content, container type (airtight vs. non-airtight), and whether the item is pre-cooked and frozen, including lines 1604206010 and 1604206090 for general preserved fish and 1604204500 for breaded minced-fish products. FDA exercises primary admissibility authority over imported seafood under the Seafood HACCP regulation, and importers must also account for potential Section 301 exposure on shipments originating from China. Correct classification hinges on the specific processing method and container format, making product specification review essential before entry.
