According to Bloomberg, several industry executives have reported that due to increased scrutiny by the US Customs and Border Protection, Bitmain Technology Co., Ltd. has experienced delays in shipping machines to US customers recently. These delays happened just as the US Department of Commerce blacklisted Xiamen Sophgo Technologies Ltd., an AI subsidiary of Bitmain, in January of this year. At that time, the US accused the company of "acting at the request of Beijing to promote China's domestic advanced chip production goals". This situation has put US President Trump's two goals in conflict: one is to gain the upper hand over China in trade, and the other is to cultivate local cryptocurrency miners to ensure that Bitcoin is "Made in America". Bitmain holds a 90% market share in the Bitcoin mining dedicated computer market, and the company was impacted by Trump's tariffs in 2018. On February 1st, Trump announced an additional 10% tariff on Chinese imports. Nuo Xu, the president of the China Digital Mining Association, said, "About three months ago, the US Customs began random inspections of almost all air freight Bitcoin mining machines." His mining farm is located in the United States. Nuo Xu added that customs officials are inspecting these machines more carefully and "requesting brokers to present certificates of origin".
