Brazil's Mines and Energy Minister, Alexandre Silveira, has expressed that potential U.S. tariffs on Brazilian ethanol would be unreasonable and highlighted the history of ethanol and sugar trade between the two countries. The U.S. is considering ending low tariffs and increasing them to match other countries' rates, which could result in higher tariffs for major trading partners by early April. Brazilian Finance Minister Fernando Haddad has indicated willingness for tariff negotiations with the U.S. However, Brazil's high tariffs on U.S. ethanol exports and low sugar export quotas to the U.S. due to high tariffs could pose challenges in these negotiations.
