0303.31.00.30 - Greenland turbot (Greenland halibut) (Reinhardtius hippoglossoides)

This HTS classification covers frozen Greenland turbot, also scientifically known as Greenland halibut (*Reinhardtius hippoglossoides*). These are flat fish, distinct from other halibut species, and the classification applies to the whole fish that has been preserved by freezing. It excludes any fillets or other fish meat that would be classified under heading 0304.

This specific subheading differentiates Greenland turbot from its sibling categories, which are dedicated to Atlantic halibut (*Hippoglossus hippoglossus*) and Pacific halibut (*Hippoglossus stenolepis*). While all are flat fish belonging to the halibut family, *Reinhardtius hippoglossoides* is a separate species with its own distinct taxonomic classification. The key distinction lies in identifying the species of halibut being imported or exported.

As this is a leaf node within the HTS structure, there are no further subcategories for this specific item. Therefore, classification decisions at this level rely solely on the accurate identification of the species as Greenland turbot and confirmation that the product is frozen and not further processed into fillets or other meat forms.
