NMFS amends the regulations that require seafood import documentation under the Magnuson-Stevens Fishery Conservation and Management Act (16 U.S.C. 1801 et seq.). The statute prohibits the importation of seafood that was harvested in violation of foreign laws, any treaty, or binding conservation measures of regional fisheries organizations to which the United States is a party. The import permitting, reporting and recordkeeping regulations facilitate enforcement of the statutory prohibition. To ensure compliance with the import monitoring program, NMFS clarifies what qualifies as the U.S. resident business address of the International Fisheries Trade Permit holder and the permit holder's obligation to ensure timely access to and production of the required supply chain records in the event of an audit NMFS also intends to include additional species under the program, such as expanding currently listed single-species to species groups and adding new species. U.S. seafood importers are likely to be affected by this rulemaking through increased reporting and recordkeeping requirements, but NOAA estimates the economic impact will be small because documentation is already completed, transmitted through the supply chain, and available to importers.
