Chinese online retailer Temu is known for its super low prices, hitting U.S. customers with massive import fees due to President Donald Trump's trade war.

In some cases, the Trump administration has more than doubled the price of many items in the e-commerce market.

According to an NBC News Review on the NBC Product List, a men's sports shorts sold for $23.61 for $23.61, and delivered at $56.36 after import fees of $32.75.

"Projects imported into the United States may be subject to import fees," a notice on the Temu checkout page said.

"These fees cover all customs-related processes and expenses, including import fees paid to the Customs Department on your behalf. The amounts listed may not represent the amount actually paid to the Customs Department," the notice said.

Some items shipped from the United States, but are still produced in China, are much more expensive than items abroad. NBC News found that a domestically shipped blender retails for $34.19 and has no import fees. Similar mixers made and shipped from China cost only $5.94, but add $8.18 to imports to U.S. customers, rather than the price of the item itself.

In many cases, Temu items shipped from domestic warehouses are now marked as "local", many of which appear at the top of the search page.

Temu did not immediately respond to a request for comment. Bloomberg reported earlier that Temu prices rose.

Trump imposed a 145% tax on Chinese goods on Monday, engaging in an ongoing confrontation between the world’s two largest economies, which led to China imposing a 125% tax on U.S. goods on Monday, and CNBC’s secretary Scott Bessent told CNBC that CNBC would pay for huge trade tensions.

Barclays analysts wrote in a note to clients on Monday that duel tariffs were so high that “a trade embargo between the two sides”. They said that while certain commodities are “currently reconnecting to non-Chinese ports” to enter the U.S. market, a large number of commodities may not find their way out.

Meanwhile, Temu shoppers in the United States expressed frustration with social media. An X user shared a photo of an online Temu shopping cart, and they charged a $90 import fee for a $64 item. Another shared photos of their cart, in which Temu charged a $135 import fee for items worth $86.

Another X user joked: "Temu needs to put a 'Trump do' sticker next to the new import fee line at checkout."

No other large Chinese online retailers, such as Tiktok Shop, seem to be affected by import fees.

Both Shein and Temu have issued notices to customers that the price adjustment will begin on April 25, which increases operating expenses “due to the latest changes in global trade rules and tariffs.”
