Section 300.204 - Effect of certification(a) If an identified nation does not receive a positive certification under this subpart ( i.e., the nation receives a negative certification or no certification is made), the fishing vessels of such nation are, to the extent consistent with international law, subject to the denial of entry into any place in the United States and to the navigable waters of the United States.(b) At the recommendation of the Secretary of Commerce ( see§300.205), certain fish or fish products from such nation may be subject to import prohibitions.(c) Any action recommended under this paragraph (c) shall be consistent with international obligations, including the WTO Agreement.(d) If certain fish or fish products are prohibited from entering the United States, within six months after the imposition of the prohibition, the Secretary of Commerce shall determine whether the prohibition is insufficient to cause that nation to effectively address the IUU fishing described in the biennial report, or that nation has retaliated against the United States as a result of that prohibition. The Secretary of Commerce shall certify to the President each affirmative determination that an import prohibition is insufficient to cause a nation to effectively address such IUU fishing activity or that a nation has taken retaliatory action against the United States. This certification is deemed to be a certification under section 1978(a) of Title 22, which provides that the President may direct the Secretary of the Treasury to prohibit the bringing or the importation into the United States of any products from the offending country for any duration as the President determines appropriate and to the extent that such prohibition is sanctioned by the World Trade Organization.(e)Duration of certification. Any nation identified in the biennial report to Congress and negatively certified will remain negatively certified until the Secretary of Commerce determines that the nation has taken appropriate corrective action to address the IUU fishing activity and/or bycatch of PLMRs for which it was identified in the biennial report. Receipt of a positive certification determination will demonstrate that appropriate corrective action has been taken by a nation to address the relevant IUU fishing activity and/or bycatch of PLMRs.(f)Consultations. NMFS will, working through or in consultation with the Department of State, continue consultations with nations that receive a negative certification with respect to the IUU fishing activities or bycatch of PLMRs described in the biennial report to Congress. The Secretary of Commerce shall take the results of such consultations into consideration when making a subsequent certification determination for such nation.
