1604.20.60.90 - Other

This classification, HTS Code 1604.20.60.90, encompasses "Other" prepared or preserved fish that do not fit into more specific subheadings within the 1604.20.60 category. It serves as a residual category for a wide array of processed fish products that have undergone preparation and preservation beyond simple canning or simple cooking. Examples include fish that may have been smoked, dried, or marinated, and then further processed in a way not explicitly defined in other classifications.

Distinguishing this category from its sibling, 1604.20.60.10 (Pre-cooked and frozen), is the absence of a pre-cooked and frozen state as the primary defining characteristic. While products in this category may coincidentally be frozen, the defining factor for 1604.20.60.90 is that they are prepared or preserved fish prepared or preserved in a manner *other than* specifically pre-cooked and frozen. This means products that are, for instance, fully cooked and then preserved in oil, sauce, or other mediums, without a primary emphasis on a pre-cooked and frozen state, would likely fall here.

As this is a leaf node, there are no further subcategories. Therefore, the classification hinges on careful consideration of the specific preparation and preservation methods applied to the fish, ensuring it does not align with any more granular or specific HTS classifications within Chapter 16. The importer must carefully examine the product's characteristics and processing to confirm it belongs in this residual "Other" classification.
