0305.69.20.00 - In immediate containers weighing with their contents 6.8 kg or less each

This HTS category, 0305.69.20.00, specifically classifies salted mackerel, or mackerel in brine, which is not dried or smoked, when it is packaged in immediate containers with a total weight (including contents) not exceeding 6.8 kilograms each. This is a critical distinction for customs purposes, as it focuses on the retail or smaller bulk packaging of this particular preserved fish product. The "other" designation within the broader category of salted or brined fish indicates that it is not subject to more specific subheadings that might exist for other types of fish or preparation methods.

When classifying, it is important to differentiate this HTS code from its sibling category, 0305.69.30.00, which would cover "other" types of salted or brined fish not specifically detailed elsewhere. This node's unique identifier lies in its explicit mention of mackerel and its specific packaging constraint. Therefore, if the product is salted mackerel in brine and is packaged in larger containers exceeding 6.8 kg, or if it is a different type of fish prepared in the same way, it would fall under a different classification.

As this HTS code represents a leaf node, there are no further subcategories. Classification is determined at this level based on the product being mackerel, preserved by salting or brining (but not dried or smoked), and its presentation in individual containers weighing 6.8 kg or less. This detailed specification ensures accurate tariff application for this specific form of preserved fish, aligning with the broader scope of Chapter 3 which deals with fish and crustaceans, molluscs and other aquatic invertebrates.
