0303.31.00.20 - Pacific halibut (Hippoglossus stenolepis)

This HTS classification specifically covers frozen Pacific halibut (Hippoglossus stenolepis). This category is part of a broader group of frozen fish, excluding fillets and other fish meat, and further narrows down to flatfish. The inclusion of "Pacific halibut" ensures that only this particular species, scientifically identified as Hippoglossus stenolepis, is classified here when imported or exported in a frozen state.

It is crucial to differentiate this code from its siblings. HTS 0303.31.00.10 covers Atlantic halibut (Hippoglossus hippoglossus), a distinct species found in different ocean regions. Similarly, HTS 0303.31.00.30 classifies Greenland turbot, also known as Greenland halibut (Reinhardtius hippoglossoides), which is yet another separate species within the flatfish family. The key distinguishing factor for this code is the precise species identification of Pacific halibut.

As this classification node represents a leaf node in the HTS structure, there are no further subcategories. This means that any frozen Pacific halibut, regardless of size, processing method (as long as it's not fillets or fish meat of heading 0304), or origin within the Pacific, will fall directly under HTS 0303.31.00.20, provided it meets the general criteria for frozen fish of Chapter 3 and the flatfish subgroup.
