According to Odaily, recent market reports indicate that the U.S. Customs and Border Protection (CBP) is currently holding certain imports of Bitmain's Antminer series at U.S. entry points. The affected models include the Antminer S21 and T21, which are part of Bitmain's latest ASIC mining equipment lineup.
Sources reveal that while the Federal Communications Commission (FCC) and CBP have targeted these specific Bitmain models, other ASIC manufacturers like MicroBT and Canaan have not been subjected to similar actions. Despite the FCC's involvement in requesting the freeze, the CBP has not provided the affected parties with detailed reasons for this action, nor have they specified the duration for which the equipment will be detained. This lack of clarity has left stakeholders seeking further information on the regulatory measures impacting the importation of these mining devices.
