Some U.S. companies have begun to pre-order excess product from Chinese suppliers, ahead of President Trump's proposed tariffs, according to Ryan Petersen, founder and CEO of shipping logistics company Flexport.

Petersen, whose company is valued north of $900 million by VC firms like Peter Thiel's Founders Fund, adds that he's preparing his more than 10,000 clients for the tariffs to go into effect.
