1604.18.90.00 - Other

This HTS subheading, 1604.18.90.00, encompasses shark fins that are prepared or preserved but are not packed in airtight containers. This category is designed to capture shark fins that have undergone processing, such as drying, salting, or being preserved in brine, but are intended for distribution or sale in packaging that is not hermetically sealed. The key differentiator from its sibling, 1604.18.10.00, is the absence of airtight packaging.

Shark fins classified here are typically intended for culinary uses, particularly in the preparation of shark fin soup, a traditional dish in some Asian cuisines. The preparation methods aim to preserve the product while retaining its characteristic texture and flavor profile. Since this is a leaf node, there are no further subcategories to explore. The classification hinges on the preparation method and the type of packaging utilized, ensuring that only non-airtight preserved shark fins fall under this specific code.
