The Uyghur Forced Labor Prevention Act (UFLPA) was signed into law by President Joe Biden on December 23, 2021, and its core import provisions took effect on June 21, 2022. The statute responds to documented allegations of state-organized forced labor involving Uyghurs and other predominantly Muslim minorities in the Xinjiang Uyghur Autonomous Region (XUAR) of the People's Republic of China.
The law's central mechanism is a rebuttable presumption: U.S. Customs and Border Protection (CBP) must assume that any good "mined, produced, or manufactured wholly or in part" in Xinjiang, or by entities on a designated UFLPA Entity List, is made with forced labor and is therefore inadmissible under Section 307 of the Tariff Act of 1930 (19 U.S.C. § 1307). Importers can rebut the presumption only by providing "clear and convincing evidence" that no forced labor was used and by fully responding to CBP inquiries.
Implementation is coordinated through the Forced Labor Enforcement Task Force (FLETF), chaired by the Department of Homeland Security, which publishes a strategy and maintains the Entity List of sanctioned producers. High-priority sectors flagged for enforcement include cotton, tomatoes, polysilicon (used in solar panels), and apparel, though the law applies economy-wide.
The UFLPA has broad extraterritorial reach because Xinjiang-origin inputs frequently enter global supply chains through third countries. It has reshaped due-diligence practices, driving demand for supply-chain traceability tools, isotopic testing, and supplier mapping. Critics in Beijing have denounced it as interference in China's internal affairs and retaliated with sanctions against U.S. officials and entities. Some U.S. industry groups have raised concerns about compliance costs and detentions of shipments lacking complete documentation.
The Act complements earlier measures, including Withhold Release Orders (WROs) on Xinjiang cotton and tomato products issued by CBP in 2020 and 2021, and parallels emerging due-diligence regimes in the EU and Canada.
Example
In 2023, U.S. Customs and Border Protection detained shipments of automotive parts from Volkswagen and other carmakers at U.S. ports under UFLPA enforcement after components were traced to a sanctioned Xinjiang supplier.
