0305.20.40.40 - Herring roe

This HTS subheading covers herring roe that has been dried, smoked, salted, or preserved in brine. Roe, in this context, refers to the eggs of fish. Therefore, this category is specifically for the processed eggs of herring, distinct from other fish products.

Unlike the sibling category for salmon roe (0305.20.40.20), this classification is exclusively for herring roe. The "Other" category at this level (0305.20.40.65) would encompass the processed roes of fish not otherwise specified. The processing methods of drying, smoking, salting, or brining are key distinguishing factors for items within heading 0305.

As this is a leaf node, there are no further subdivisions under this specific HTS code. Classification at this level relies on the accurate identification of the species of fish (herring) and the form of preservation (dried, smoked, salted, or in brine) of its roe.
