0306.12.00.10 - In brine

This HTS classification, 0306.12.00.10, specifically designates frozen lobster (Homarus spp.) that are preserved "in brine." This category encompasses whole or processed lobsters that have been preserved in a saline solution. The brine serves to maintain the lobster's freshness and texture during frozen storage and transportation, and is a defining characteristic for classification purposes.

It is crucial to distinguish this category from its sibling, 0306.12.00.30, which covers "Other" frozen lobsters. While both refer to frozen lobsters, 0306.12.00.10 is exclusively for those preserved in brine. The "Other" classification would apply to frozen lobsters that are not in brine, such as those frozen dry or in other packaging mediums that do not involve a saline solution. The presence or absence of brine is the sole differentiating factor at this level.

As this is a leaf node within the HTS structure, there are no further subcategories to explore. Classification at this point is determined by the presence of brine as the preservative for frozen lobsters of the genus Homarus. Therefore, any frozen lobster product meeting the description of being preserved in brine will fall under this specific HTS code.
