0305.39.20.00 - Herrings, in immediate containers weighing with their contents 6.8 kg or less each

This HTS classification, 0305.39.20.00, specifically covers dried, salted, or brined fish fillets of herrings. The crucial differentiating factor within this subheading is the type of fish: herrings. The presentation also specifies that these fillets must be contained in immediate containers, each weighing 6.8 kilograms or less with their contents. This category is part of the broader group for fish, dried, salted or in brine; smoked fish, whether or not cooked before or during the smoking process, and more narrowly, other fish fillets that are dried, salted, or in brine but not smoked.

To distinguish this category from its siblings, it's important to note that 0305.39.40.00 covers mackerel fillets under identical packaging conditions. Therefore, the fundamental difference lies in the species of fish. While both deal with dried, salted, or brined fillets in smaller containers, the tariff line is specific to herrings.

As this is a leaf node in the HTS structure, there are no further subdivisions under 0305.39.20.00. Classification at this level is determined by the species of fish (herring), the preparation method (dried, salted, or in brine, but not smoked), and the size of the immediate packaging.
