0304.82 - Trout (Salmo trutta, Oncorhynchus mykiss, Oncorhynchus clarki, Oncorhynchus aguabonita, Oncorhynchus gilae Oncorhynchus apache and Oncorhynchus chrysogaster):

This HTS classification covers frozen fillets and other meat of various trout species, specifically *Salmo trutta*, *Oncorhynchus mykiss* (rainbow trout), *Oncorhynchus clarki* (cutthroat trout), *Oncorhynchus aguabonita* (golden trout), *Oncorhynchus gilae* (Gila trout), *Oncorhynchus apache* (Apache trout), and *Oncorhynchus chrysogaster* (Mexican golden trout). This category specifically applies to the prepared flesh of these fish, excluding whole fish or fish parts not considered "fillets" or "other meat."

This classification is distinguished from its siblings primarily by the specific species of fish it encompasses. For instance, sibling category 0304.81 pertains to various salmon species, while 0304.83 deals with flatfish. Category 0304.82.00.00 is narrowly defined by its inclusion of trout species, making it crucial to verify the species of origin when classifying.

Within this trout classification, two subcategories exist to further refine the classification based on the product's presentation and intended use. Subcategory 0304.82.10.00 is reserved for skinned frozen trout blocks exceeding 4.5 kg, specifically imported for further processing such as mincing or cutting into uniform pieces. All other presentations of frozen trout fillets or meat, not meeting the specific criteria of 0304.82.10.00, fall under the broader "Other" subcategory, 0304.82.50.00.
