In December 2021, President Biden signed the UFLPA into law to restrict the import of goods mined, produced, or manufactured, in whole or in part, using forced labor from the Xinjiang Uygur Autonomous Region (XUAR), which we discussed here. A key feature of the law was its focus on polysilicon imports as a high-priority sector for enforcement. The law required U.S. Customs and Border Protection (CBP) to implement the UFLPA’s requirements starting in June 2022. The implementing task force’s 2023 annual update reports that in the last year or so the CBP has examined for enforcement action more than 4,000 shipments valued at over $1.3 billion.
