# China Solar Market Remade Itself Around U.S. Forced Labor Law
The Chinese solar industry restructured its entire supply chain to circumvent the Uyghur Forced Labor Prevention Act, a Biden administration trade law designed to block goods made with forced labor. Companies relocated manufacturing plants, shifted production to subsidiaries, and obscured ownership structures to evade scrutiny from U.S. Customs and Border Protection.
The UFPLA, enacted in December 2021, targets products from Xinjiang or those made with Uyghur labor. Solar polysilicon, a critical component in panel manufacturing, faced intense regulatory pressure because major production concentrated in Xinjiang. Rather than ceasing operations there, Chinese firms simply reorganized their business models.
Major solar manufacturers including LONGi Green Energy and Daqo New Energy maintained production in restricted regions but created complex corporate structures that obscured supply chain origins. Some companies established operations in Southeast Asia or other Chinese provinces, creating layered subsidiaries that made tracking forced labor connections difficult for U.S. authorities.
A Reuters investigation found that polysilicon production actually expanded in Xinjiang even as enforcement pressure increased. Companies listed different ownership entities on export documents than on corporate registration filings, making it nearly impossible for customs officials to connect final products to prohibited production facilities.
The law's enforcement faced practical limitations. U.S. regulators lack real-time visibility into Chinese corporate restructurings. By the time investigators documented a company's supply chain changes, firms had already shifted to new arrangements. The solar industry's rapid growth and complexity created enforcement gaps that Chinese producers exploited.
The restructuring raises questions about the law's effectiveness. While the UFPLA intended to sever American markets from Xinjiang labor practices, Chinese firms demonstrated that regulatory obstacles prompt adaptation rather than compliance. The solar market transformation shows how enforcement mechanisms designed for
