More than 1,000 shipments of solar energy components worth hundreds of millions of US dollars have piled up at US ports since June under a new law banning imports from China’s Xinjiang region over concerns about slave labor, US federal customs officials and industry sources said.
The level of seizures, which has not previously been reported, reflects how a policy intended to heap pressure on Beijing over its Uighur detention camps in Xinjiang risks slowing the efforts of US President Joe Biden’s administration to decarbonize the US power sector to fight climate change.
US Customs and Border Protection has seized 1,053 shipments of solar energy equipment between June 21 — when the Uyghur Forced Labor Protection Act (UFLPA) went into effect — and Oct. 25, it said in response to a public records request, adding that none of the shipments have yet been released.

The agency would not reveal the manufacturers or confirm details about the quantity of solar equipment in the shipments, citing federal law that protects confidential trade secrets.
However, three industry sources with knowledge of the matter said the detained products include panels and polysilicon cells, likely amounting to up to 1 gigawatt of capacity and primarily made by three Chinese manufacturers — Longi Green Energy Technology Co (隆基綠能科技), Trina Solar Co (天合光能) and JinkoSolar Holding Co (晶科能源).
Combined, Longi, Trina and Jinko typically account for up to one-third of US panel supplies. However, the companies have halted new shipments to the US over concerns additional cargoes would also be detained, the industry sources said. The sources asked not to be named because they were not authorized to speak publicly on the matter.
China denies abuses in Xinjiang. It initially denied the existence of any detention camps, but then later said it had set up “vocational training centers” to curb what it said was terrorism, separatism and religious radicalism in Xinjiang.
In an e-mail, Jinko said it is working with US Customs and Border Protection on documentation proving its supplies are not linked to forced labor and is “confident the shipments will be admitted.”
The bottleneck is a challenge to US solar development at a time the Biden administration is seeking to decarbonize the US economy and implement the Inflation Reduction Act (IRA), a new law that encourages clean energy technologies to combat climate change.
Solar installations in the US slowed by 23 percent in the third quarter, and nearly 23 gigawatts of solar projects are delayed, largely due to an inability to obtain panels, the American Clean Power Association trade group said.
The association urged the Biden administration to streamline the vetting process for imports.
“After more than four months of solar panels being reviewed under UFLPA, none have been rejected and instead they remain stuck in limbo with no end in sight,” it said in a statement.
The UFLPA essentially presumes that all goods from Xinjiang are made with forced labor and requires producers to show sourcing documentation of imported equipment back to the raw material to prove otherwise before imports can be cleared.
RUN IT BACK: A succesful first project working with hyperscalers to design chips encouraged MediaTek to start a second project, aiming to hit stride in 2028 MediaTek Inc (聯發科), the world’s biggest smartphone chip supplier, yesterday said it is engaging a second hyperscaler to help design artificial intelligence (AI) accelerators used in data centers following a similar project expected to generate revenue streams soon. The first AI accelerator project is to bring in US$1 billion revenue next year and several billion US dollars more in 2027, MediaTek chief executive officer Rick Tsai (蔡力行) told a virtual investor conference yesterday. The second AI accelerator project is expected to contribute to revenue beginning in 2028, Tsai said. MediaTek yesterday raised its revenue forecast for the global AI accelerator used
TEMPORARY TRUCE: China has made concessions to ease rare earth trade controls, among others, while Washington holds fire on a 100% tariff on all Chinese goods China is effectively suspending implementation of additional export controls on rare earth metals and terminating investigations targeting US companies in the semiconductor supply chain, the White House announced. The White House on Saturday issued a fact sheet outlining some details of the trade pact agreed to earlier in the week by US President Donald Trump and Chinese President Xi Jinping (習近平) that aimed to ease tensions between the world’s two largest economies. Under the deal, China is to issue general licenses valid for exports of rare earths, gallium, germanium, antimony and graphite “for the benefit of US end users and their suppliers
Dutch chipmaker Nexperia BV’s China unit yesterday said that it had established sufficient inventories of finished goods and works-in-progress, and that its supply chain remained secure and stable after its parent halted wafer supplies. The Dutch company suspended supplies of wafers to its Chinese assembly plant a week ago, calling it “a direct consequence of the local management’s recent failure to comply with the agreed contractual payment terms,” Reuters reported on Friday last week. Its China unit called Nexperia’s suspension “unilateral” and “extremely irresponsible,” adding that the Dutch parent’s claim about contractual payment was “misleading and highly deceptive,” according to a statement
The Chinese government has issued guidance requiring new data center projects that have received any state funds to only use domestically made artificial intelligence (AI) chips, two sources familiar with the matter told Reuters. In recent weeks, Chinese regulatory authorities have ordered such data centers that are less than 30 percent complete to remove all installed foreign chips, or cancel plans to purchase them, while projects in a more advanced stage would be decided on a case-by-case basis, the sources said. The move could represent one of China’s most aggressive steps yet to eliminate foreign technology from its critical infrastructure amid a
