"This is to inform you that U.S. Customs and Border Protection (CBP) seized the property described below at SF INTL AIRPORT on January 10, 2025: BITMAIN S21 PRO 200TH CRYPTOCURRENCY MINING MACHINE," states a CBP letter shared with Blockspace Media.
  • The letter states that miners were "seized and subject to forfeiture" under 19 USC 1595a(c)(2)(A) for involving unauthorized communication devices, interfering radio frequency equipment, and non-compliant FCC devices.
"Virtually every Asian ASIC manufacturer is being impacted by customs clearance issues," said Synteq Digital CEO Taras Kulyk.
  • Additionally, the custom clearance issues are now occurring at numerous ports instead of just Detroit and San Francisco.
  • One affected company said it is seeking partners to take legal action against the government for the seizures.
