1605.51.05.00 - Products containing fish meat; prepared meals

This HTS code encompasses prepared or preserved products derived from oysters. The classification specifically targets goods where oyster meat is the primary component or a significant ingredient in a composite product. Examples include canned oysters, smoked oysters, oysters preserved in brine or oil, and prepared dishes where oysters are a key ingredient, such as oyster stews or oyster gratins. The preparation method can involve cooking, canning, freezing, drying, or any other process that renders the oysters ready for consumption.

It is important to distinguish this category from sibling categories such as "Other" molluscs, which would cover prepared or preserved products from clams, mussels, scallops, or squid, among others. This specific heading is exclusively for products originating from oysters, meaning that if the primary aquatic invertebrate is not an oyster, it would fall under a different classification.

As a leaf node, HTS 1605.51.05.00 does not have further subcategories. Therefore, the focus for classification under this code rests on ensuring the product is indeed prepared or preserved, contains oyster meat, and is not a more general preparation of molluscs or other aquatic invertebrates. The intent is to precisely identify oyster-based foodstuffs at this level of detail within the broader chapter on preparations of aquatic invertebrates.
