Shoppers got a little relief this week from a giant tariff on previously cheap, duty-free goods from China. But the tariffs that do remain are still poised to derail the shopping habits of millions of Americans who shop at ultra-low-priced e-commerce sites like Shein and Temu.

The Trump administration has made moves to ease tariff tensions with China, but the situation remains uncertain in the longterm.
