US Bitcoin mining operations are experiencing delays as Bitmain Antminer shipments are being held by the Customs and Border Protection agency. The detained equipment, including Bitmain’s S21 and T21 ASICs, is crucial for Bitcoin mining. Some mining companies have reported waiting up to two months for the equipment, incurring holding fees exceeding $200,000 for 200 units. The CBP is acting on the FCC's request, possibly due to Bitmain's ties to Sophgo, a chip designer under US investigation. This delay underscores the challenges US miners face relying on Chinese-manufactured equipment. Despite trade restrictions, Bitmain has expanded globally to mitigate tariffs. The situation also raises concerns about China's influence on the crypto sector. Regulatory clarity is sought as costs rise and delays persist. The CBP and FCC have not issued public statements on the detained shipments.
