The White House has confirmed that President Donald Trump signed “take-it-or-leave-it” tariff letters to a first group of 12 trading partners after talks stalled ahead of the self-imposed July 9 deadline. Copies are scheduled to leave Washington on Monday, July 7; additional batches will follow until every country still lacking a deal has been notified. Each letter sets a specific import duty—anywhere from the 10 percent baseline to as high as 70 percent—with the rates to take effect on August 1 unless a bilateral accord is reached first.
