Frozen Halibut and Greenland Turbot (Whole, Not Fillets or Roe)

The separation reflects both biological distinctions — Atlantic halibut (Hippoglossus hippoglossus) and Pacific halibut (H. stenolepis) are different species, and Greenland turbot is a separate genus — and trade-policy considerations, as each species has a distinct supply base and may carry different duty rates. Importers must identify the species and, for halibut, the ocean of catch, to select the correct line. Misclassification between lines can result in duty underpayment or overpayment and potential CBP penalties.

The International Pacific Halibut Commission sets annual catch limits for Pacific halibut in Convention waters, which constrains total harvest in both the US and Canada. When quotas are reduced, frozen whole halibut supply tightens and prices rise. Importers sourcing from Canada should monitor IPHC annual meeting outcomes, typically announced in the first quarter, to anticipate supply availability for the coming season.
