This final action implements the import provisions of the Marine Mammal Protection Act (MMPA). This rule establishes conditions for evaluating a harvesting nation's regulatory program to address incidental and measures to address intentional mortality and serious injury of marine mammals in fisheries that export fish and fish products to the United States. Under this rule, fish and fish products from fisheries identified by the Assistant Administrator in the List of Foreign Fisheries can only be imported into the United States if the harvesting nation has applied for and received a comparability finding from NMFS. The rule establishes procedures that a harvesting nation must follow and conditions to meet, to receive a comparability finding for a fishery. The rule also establishes provisions for intermediary nations to ensure that intermediary nations do not import, and re- export to the United States, fish or fish products subject to an import prohibition. Agency actions and recommendations under this rule will be in accordance with U.S. obligations under applicable international law, including, among others, the World Trade Organization (WTO) Agreement.
