1604.20.05.90 - Other

This category, HTS 1604.20.05.90, encompasses "Other" prepared or preserved fish products that do not fit into the more specific subcategories. It serves as a residual category for a wide array of processed fish preparations that are not meals containing other aquatic invertebrates and are not categorized as prepared meals themselves. The key characteristic is that these are distinct preparations of fish, which have undergone processing such as cooking, salting, drying, or marinating, and are presented in a manner ready for consumption or further culinary use.

Unlike the sibling category 1604.20.05.10, which specifically covers prepared meals (implying a complete dish with multiple components), this category focuses on individual or primary fish preparations. For instance, it would include items like smoked salmon portions, canned sardines in oil, pickled herring, or fish pâtés that are not part of a composite meal. The processing and presentation are key determiners; the product is primarily fish and is not designed as a fully assembled dish.

As this is a leaf node in the HTS classification system, there are no further subcategories. Therefore, classification within 1604.20.05.90 relies on a thorough review of the specific product's composition, processing method, and packaging to ensure it does not meet the criteria for any more specific heading or subheading within Chapter 16. The emphasis remains on identifying products that are undeniably prepared or preserved fish and do not fall under more detailed enumerations.
