Temu saw its spending growth among US customers plummet in April, slowing from nearly 50% year-over-year growth at the start of the month to nearly 0% at the end, according to credit and debit card data analyzed by Consumer Edge.

Shein also suffered a steep decline in US spending growth, cooling from 30% at the start of April to just 20% at the end.

That spending slowdown is no coincidence.

In early April, Trump killed a trade loophole known as "de minimis" that Temu and Shein used to avoid paying import taxes and slapped them with a 120% tariff – though he effectively lowered that rate to 30% in an executive order earlier this week, Reuters reported on Wednesday.

Though the White House lowered the rate to 54%, the majority of Temu and Shein packages are shipped through commercial carriers, which can skip "de minimis" fees and pay the lower 30% tariff on China instead, sources told Reuters.

Temu has slowly started adding items shipped directly from China back to its website, though it's attaching higher price tags – like an $11 screen protector, which costs 16% more than its original price, the Wall Street Journal reported on Wednesday.

The steep taxes Trump put in place earlier in April had forced the fast-fashion sites to hike prices and halt shipments of Chinese products.

In the three weeks ended April 27, former Temu and Shein shoppers spent 21% more at Nordstrom Rack than the year before, according to Consumer Edge. That's more than the 12% overall spend growth at Nordstrom Rack.

"It could be that these folks have been shopping at department stores for a while, were attracted to affordable prices from Temu and Shein, and then became a little cold on those brands amid everything going on," Michael Gunther, vice president and head of insights at Consumer Edge, told The Post.

Former Temu and Shein shoppers – who made multiple purchases at the Chinese sites earlier in the year but none in March or April – brought their business to Bloomingdale's, Old Navy and Kohl's over the same three weeks, according to Consumer Edge.

They spent 52%, 12% and 6% more at these retailers than the year before, outpacing overall spending growth from all customers, according to the data. 

Much like Temu and Shein, department stores are a one-stop shop – selling apparel, footwear, beauty products, furniture and kitchen appliances. 

"There's a huge selection, lot of different brands, lot of different types of products in one place," Gunther told The Post. "Maybe it's that sort of thing that's similar to the mindset of someone who might have been shopping at Temu before."
