Brazil is considering granting an import quota of 750,000 metric tons of U.S. wheat per year without tariffs in exchange for other trade concessions, according to Brazilian officials. That is about 10% of Brazilian annual wheat imports and is part of a two-decade-old commitment to import 750,000 metric tons of wheat a year free of tariffs that Brazil made — but never kept — during the World Trade Organization's Uruguay Round of talks on agriculture.
