Atlantic and Pacific halibut fillets in industrial frozen block format enter under HTS 0304831025, explicitly excluding Greenland halibut (Reinhardtius hippoglossoides), which has its own dedicated line. The over-4.5 kg skinned block specification targets seafood processors producing minced or portioned halibut for foodservice and retail value-added products. Pacific halibut (Hippoglossus stenolepis) is subject to quota management by the International Pacific Halibut Commission, which can affect seasonal availability and pricing for US processors. FDA seafood HACCP requirements apply at importation, and the species exclusion for Greenland halibut makes accurate scientific identification on commercial invoices a compliance priority.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Commercial invoices and catch certificates should specify the scientific name — Hippoglossus hippoglossus for Atlantic halibut or Hippoglossus stenolepis for Pacific halibut. Fishing vessel logs, MSC chain-of-custody certificates, or supplier affidavits referencing the harvest area can further substantiate the species identity if CBP requests additional information.
IPHC quotas govern catch limits for Pacific halibut but do not directly alter the HTS classification or duty rate at US Customs. However, quota-driven supply constraints can affect the volume and timing of shipments, and importers should confirm that their foreign supplier's catch is covered by a valid IPHC allocation to avoid potential fisheries-law complications.
