0304.89.50.50 - Orange roughy (Hoplostethus atlanticus)

This classification, HTS 0304.89.50.50, specifically identifies orange roughy (Hoplostethus atlanticus) fillets and other fish meat, whether or not minced, that are frozen. This category falls under the broader scope of frozen fillets of other fish, which encompasses a diverse range of edible fish meat not specifically listed in preceding subheadings.

Within its sibling categories, orange roughy is distinguished by its specific species identification. While other sibling entries might cover general categories like "Fresh-water fish" or list specific fish like Atlantic ocean perch, ocean catfish, or dolphin (mahi mahi), this subheading isolates the orange roughy for precise tariff application. This specificity is crucial for accurate duty assessment and trade data collection.

As this is a leaf node, there are no further subcategories. Therefore, classification under this code is determined solely by the product being frozen fillets or other minced meat of the orange roughy species. Importers should ensure that the imported goods are indeed the specified species and are presented in a frozen state to correctly utilize this HTS code.
