0305.61 - Herrings (Clupea harengus, Clupea pallasii):

This HTS classification, 0305.61, specifically covers herrings, identified by the scientific names *Clupea harengus* and *Clupea pallasii*, that have been salted but not dried or smoked, or are packed in brine. This category falls under the broader heading for dried, salted, or brined fish, as well as smoked fish. The key defining characteristic for goods classified here is the preservation method: salting or brining, without subsequent drying or smoking processes.

To differentiate this category from its siblings, it's important to note that 0305.62 pertains exclusively to salted or brined cod, while 0305.63 covers salted or brined anchovies. Other sibling categories, such as 0305.64 and 0305.69, address a wider range of fish species or "other" varieties prepared under similar conditions. Therefore, the classification at 0305.61 is narrowly defined to include only herrings preserved through salting or brining.

Within this classification, subcategories further refine the classification based on packaging. 0305.61.20.00 applies to herrings in brine or salted, presented in immediate containers that weigh 6.8 kg or less, including their contents. The subcategory 0305.61.40.00 encompasses all other shipments of salted or brined herrings that do not meet the weight criteria of the preceding subcategory. This distinction is crucial for accurate reporting and tariff application.
