US President Donald Trump said his administration will probably start notifying trading partners Friday of the new US tariff on their exports effective Aug. 1, while reiterating a preference for simplicity over complicated negotiations five days before his deadline for deals.

The president said the U.S. is poised to inform many trading partners of unilateral tariff rates of up to 70%, putting global investors on the defensive.

With just five days remaining in the tariff moratorium, the White House is expected to begin delivering a message to a dozen or so countries: Time is up, and here’s your new rate.
