Affected by speculation of sanctions, US Customs detained Bitmain S21/T21 mining machines for two months

According to Blockspace, at the request of the Federal Communications Commission (FCC), the US Customs and Border Protection (CBP) has detained Bitmain Antminer S21 and T21 series mining machines at ports across the country for two months. It is reported that seven American mining companies have not yet been informed of the clear reasons for the delay and the timeline for resolving it. CBP is charging daily storage fees, and some companies' fees have exceeded $200000. This detention does not seem to have affected other manufacturers such as MicroBT or Canaan. Industry speculation suggests that the detention may be related to Sophgo, a chip supplier currently under investigation for US sanctions. Sophgo was founded in 2019 by the co-founder of Bitmain, Jenk Group, and its chips are used in some Bitmain mining machines, including the S19 series. Previously, TSMC had stopped supplying chips to Sophgo. Trump recently stated that his administration is committed to building the United States into a Bitcoin mining hub; Strong Country&34;, And appointed cryptocurrency supporter Howard Lutnick as Secretary of Commerce.
