As tariffs are a huge political topic around the globe, two huge China-founded e-commerce sites are reacting to the sudden increase in costs. Temu and Shein have announced they plan to raise prices for U.S. customers starting next week, a direct response to President Trump's hike in tariffs. Both companies said they would be making “price adjustments” starting April 25, although neither provided details about the size of the increases. The interesting thing: the companies have different owners, yet their announcements were nearly identical. The 145-percent tariff President Trump placed on most products made in China, along with his decision to end a customs exemption that allows goods worth less than $800 to come into the U.S. duty-free, have caused both platforms to reassess how they do business with the US.
