0302.91.20.00 - Sturgeon roe

This HTS classification, 0302.91.20.00, specifically covers sturgeon roe when it is fresh or chilled. Sturgeon roe, commonly known as caviar, is the unprocessed egg masses of sturgeon fish. This classification focuses exclusively on this particular type of fish roe, distinct from other fish eggs or byproducts.

At this level, it is important to differentiate this classification from its sibling category, 0302.91.40, which is designated for "Other" edible fish offal that are livers, roes, and milt. While 0302.91.20.00 is specific to sturgeon roe, 0302.91.40 encompasses all other types of fish roes, livers, and milts not otherwise specified. Therefore, the key distinguishing factor is the species of fish from which the roe is derived.

As this is a leaf node within the HTS, there are no further subcategories that subdivide sturgeon roe. Classification at this point is definitive, meaning goods meeting the description of fresh or chilled sturgeon roe should be classified under this specific code. The context of Chapter 3, which deals with fish and crustaceans, shellfish, and other aquatic invertebrates, provides the overarching framework for this classification.
