1604.17 - Eels:

This HTS classification covers prepared or preserved eels. This section of Chapter 16 focuses on fish that are either presented whole or in pieces, but have not been minced. The inclusion of eels here signifies that these products are processed and packaged in a way that goes beyond fresh or chilled preparations, typically involving methods such as canning, smoking, or cooking.

Within the broader category of prepared or preserved fish, this HTS code is specifically for eels. It is distinguished from sibling categories such as salmon (1604.11), herrings (1604.12), sardines (1604.13), and tuna (1604.14) by the species of fish. While all fall under the umbrella of prepared fish, the tariff rate and specific import/export regulations are tailored to the distinct types of aquatic life.

The subcategories for 1604.17 further refine the classification based on the packaging method. Goods are either classified under "In airtight containers" (1604.17.10.00), which typically refers to items like canned eels, or under "Other," which would encompass other forms of preservation and packaging that do not meet the criteria for airtight containers. This distinction is crucial for determining applicable duties and import requirements.
