Chemical products companies in Brazil, which exported $2.4 billion to the U.S. last year, face a slew of contract cancellations as President Donald Trump has threatened a new 50% tariff on the South American nation's exports from August 1. Since Trump's announcement, export orders have been canceled for certain resins and compounds used to make fertilizers, which Brazil supplies to the U.S. agriculture sector, Andre Cordeiro, head of Brazilian chemical lobby Abiquim, said on Friday. "Fundamentally, these decisions are being made because the bet is that he will actually apply the tariff," Cordeiro said. One company in Brazil had all its contracts for exports to the U.S. canceled, Cordeiro said, adding that other businesses have seen some of their contracts canceled. There are also cases where sellers had secured export financing for the order, which was later revoked.
