0303.91.40.20 - Herring roe

This category specifically classifies frozen herring roe intended for consumption. It encompasses the entire egg mass of herring, which is typically harvested and then frozen to preserve its quality for later use in various culinary applications, such as sushi, spreads, or as a delicacy. The "Other" designation within this sub-heading signifies that while it pertains to roe, it is not roe from species explicitly listed in its sibling categories.

Distinguishing this classification from its siblings is crucial for accurate import and export procedures. Unlike salmon roe (0303.91.40.40), Alaska pollock roe (0303.91.40.50), or mullet roe (0303.91.40.60), this HTS code is exclusively for herring roe. The other sibling category (0303.91.40.95) serves as a residual for any roe not otherwise specified, highlighting the need for precise identification of the fish species from which the roe originates.

As this HTS code is a leaf node, there are no further subcategories. Therefore, the classification hinges entirely on the accurate identification of the product as frozen herring roe, distinct from the roe of other fish species detailed in adjacent codes. Classification relies on verifiable documentation, such as import declarations and product specifications, that clearly identify the species as herring.
