1604.31.00.00 - Caviar

This HTS classification, 1604.31.00.00, specifically covers true caviar, which are the processed, salted eggs of sturgeon and other fish. This category is distinct from its sibling, 1604.32, which is designated for "caviar substitutes." While both may resemble caviar in appearance, caviar substitutes are typically derived from the eggs of non-sturgeon fish or are entirely artificial products designed to mimic the texture and flavor of true caviar. The key differentiator lies in the species of origin for the fish eggs.

As this is a leaf node in the HTS classification system, there are no further subcategories under 1604.31.00.00. Therefore, the classification is applied directly to goods meeting the definition of true caviar. When classifying, it is crucial to verify the origin of the fish eggs to ensure accurate classification. The preparation process, including salting, is a key characteristic for items falling under this heading, distinguishing them from fresh or simply chilled fish eggs.
