Chinese online retailer Temu, known for its ultralow prices, is hitting U.S. customers with hefty import charges due to President Donald Trump's trade war.

Tariffs imposed by the Trump administration have in some cases more than doubled the prices of items on the e-commerce marketplace.

A three-pack of men's athletic shorts advertised as on sale for $23.61 with free shipping came out to $56.36 after a $32.75 import charge, according to an NBC News review of product listings.

A notice on Temu’s checkout page says that “items imported into the U.S. may be subject to import charges.”

“These charges cover all customs-related processes and cost, including import fees paid to customs authorities on your behalf. The amount listed may not represent the actual amount paid to customs authorities,” the notice said.

Some items that are shipped from the U.S., yet still manufactured in China, showed a much higher price tag than those made and shipped abroad. One domestically shipped blender retailed for $34.19 and had no import fees, NBC News found. A similar blender manufactured and shipped from China cost only $5.94, but it came with an added $8.18 in import charges for U.S. customers — more than the price of the item itself.

In many cases, Temu items that are shipped from domestic warehouses are now labeled “local,” with many appearing at the top of the search page for U.S. users.

Temu didn't immediately respond to a request for comment. Bloomberg earlier reported on the Temu price hikes.
