0304.59.00.55 - Greenland turbot (Greenland halibut), (Reinhardtius hippoglossoides)

This classification, HTS 0304.59.00.55, specifically pertains to Greenland turbot, also known as Greenland halibut (Reinhardtius hippoglossoides), when presented as fresh or chilled fillets or other fish meat, whether or not minced. This designation is crucial for accurate customs declarations, distinguishing this particular flatfish from other species within the broader category of "Other" fresh or chilled flat fish.

Within the 'Other' flat fish subcategory (0304.59.00), Greenland turbot is distinct from sole (0304.59.00.40), plaice (0304.59.00.45), and flounder (0304.59.00.50). While all are flatfish, the distinct biological species and commercial characteristics of Greenland turbot necessitate this specific subheading for precise tariff application. The classification relies on the scientific identification of the fish species.

As this is a leaf node within the Harmonized Tariff Schedule, there are no further subdivisions under HTS 0304.59.00.55. Therefore, all fresh or chilled fillets, other fish meat (including minced forms), of Greenland turbot (Greenland halibut) fall directly under this code, provided they meet the general criteria of being fresh or chilled and derived from the specified flatfish species.
