Greenland halibut (*Reinhardtius hippoglossoides*), also marketed as Greenland turbot, occupies a distinct commercial niche from true halibut — it is a deep-water species with higher fat content and softer flesh, often used in smoked and value-added preparations. Classified under 0302210090 when shipped fresh or chilled in whole or dressed form, it is traded separately from Atlantic and Pacific halibut at the 10-digit level. Supply originates largely from the North Atlantic and Arctic fisheries, with Greenland and Iceland among the key harvesting regions. FDA HACCP compliance governs entry, and importers should ensure species labeling aligns with FDA's seafood list to avoid misbranding exposure.
