US bars imports from 43 firms, squeezing solar Bitcoin miner margins

The US added 43 companies to its forced-labor import blacklist on July 31, a move expected to raise equipment costs and complicate supply chains for solar-powered Bitcoin miners. US Customs and Border Protection enforces the restrictions under the Uyghur Forced Labor Prevention Act of 2021, which prohibits all goods made in the Xinjiang Uyghur Autonomous Region.

The expanded blacklist is part of a broader US push on forced labor in trade. The Office of the US Trade Representative last week imposed tariffs across 60 economies, deeming them to have failed to adopt forced-labor import prohibitions, according to a CSIS analysis. Countries that adopted full or partial prohibitions faced a 10 percent tariff, while those without any mechanism faced 12.5 percent. "Import prohibitions are a tool of last resort that kick in when corporate or state behavior is unchanged after significant worker and civil society engagement," Laura T. Murphy, senior associate in the Human Rights Initiative at CSIS, said.

The compliance burden is compounding for miners. CBP has recovered $85 million in withheld wages and recruitment fees from companies subject to forced-labor prohibitions since 2018, and has removed restrictions on 16 firms after remediation, the CSIS analysis shows. The One Big Beautiful Bill Act, enacted July 4, 2025, requires storage projects beginning construction in 2026 to source at least 55 percent of costs from non-prohibited foreign entities to qualify for investment tax credits, a threshold rising to 75 percent by 2030.

Solar-powered Bitcoin miners rely on imported panels, inverters, and battery components, many of which trace back to restricted supply chains. Roughly 80 percent of planned 2026 US battery additions are concentrated in Texas, California, and Arizona, according to the Energy Information Administration, leaving miners pairing solar with storage a narrowing window to secure qualifying equipment. Developers plan to add 24 gigawatts of utility-scale battery storage to the US grid in 2026, up from a record 15 gigawatts in 2025.

The mining economics are shifting as a result. Bitcoin miners that pair solar generation with battery storage to smooth intermittent output now face higher landed costs on both fronts, as tariffs on imported battery components remain elevated and the blacklist narrows eligible suppliers. The UFLPA has already shown that corporations will pivot quickly to production outside a region using state-imposed forced labor when there is a legal and financial cost for noncompliance, according to CSIS.

For miners, the stakes are direct: equipment costs rise, project timelines stretch, and margins compress. Companies in the solar, apparel, flooring, and automotive industries have already diversified supply chains to source untainted materials under the UFLPA, according to CSIS, and mining operators are expected to follow. Operators that locked in qualifying battery supply agreements before mid-year are best positioned, while those still negotiating equipment contracts face tighter timelines and higher landed costs.

The near-term outlook for mining-related stocks and token prices is bearish as operators absorb the added cost of compliance. The next regulatory milestone is the 2026 construction-start threshold for tax-credit eligibility, which will determine how many planned projects can capture the federal credits that underpin their financing. Miners that fail to secure qualifying supply chains by that date face either higher effective costs or the loss of tax incentives entirely, a gap that could widen the cost advantage of larger operators with established procurement networks.
