0302.21.00.10 - Atlantic

This HTS classification, 0302.21.00.10, specifically covers fresh or chilled Atlantic halibut. This designation pertains to the flatfish species belonging to the genus *Hippoglossus*, commonly known as Atlantic halibut, when imported in a fresh or chilled state. It is important to note that this classification excludes fish fillets and other fish meat of heading 0304, as well as edible fish offal.

Distinguishing this category from its siblings, 0302.21.00.20 refers to Pacific halibut, a distinct species with different geographical origins. Subcategory 0302.21.00.90 encompasses other flatfish within this group, including Greenland turbot, which, while similar, is scientifically classified differently and often traded and regulated as a separate entity. Therefore, the classification hinges on precise species identification and geographical origin.

As this is a leaf node in the HTS structure, there are no further subcategories. Classification decisions at this level rely on accurate identification of the species as Atlantic halibut and confirmation that the product is presented in a fresh or chilled condition, adhering to the preceding broad categories of flat fish and the general scope of Chapter 3 for fish and fish products.
