(Bloomberg) -- Products made in China’s western province of Xinjiang are being sold to US consumers through the online shopping platform Temu, in breach of a US ban that forbids goods from the region due to links to forced labor, according to research by a global supply chain verification firm.

Temu, owned by PDD Holdings Inc., which operates Chinese e-commerce site Pinduoduo, launched in the US in September and quickly became the most downloaded app on Apple Inc.’s US App Store. Its marketplace carries clothes and home decor at rock-bottom prices, and the company is aiming to take on global retail behemoths like Amazon.com Inc. and Ebay Inc.

But Tel Aviv-based Ultra Information Solutions says it found at least 10 items made or sold by businesses located in Xinjiang that are also available in the US on Temu, where their company links and origins are obscured. Ultra used its digital vetting platform Publican to compare products sold on Temu, such as sandals, sunglasses and other items, with those sold by the parent company inside China.

“It’s a systematic violation of US trade policies,” said Ultra co-founder Ram Ben Tzion.

Representatives for Temu and PDD didn’t reply to multiple requests for comment.

Citing what the US State Department has called “horrific abuses” against the Uyghur people of Xinjiang, who are predominantly Muslim, federal officials banned the importation of cotton from the region in 2021 and expanded the law and its enforcement to all Xinjiang products last year under the Uyghur Forced Labor Prevention Act. Statements from former detainees and reports from an array of researchers and advocacy groups have alleged that the Chinese government put more than 1 million people in detention camps in the region and that laborers in fields and factories were forced or coerced. The Chinese government has said the camps are for re-education purposes.
