US Bitcoin miner tariffs are producing nine-figure liabilities for public miners, as US Customs applies a 57.6% duty on Chinese-made rigs, creating potential $100M+ hits that will compress margins, reduce mining ROI and force operational and financial adjustments across listed mining firms.
Tariffs: 57.6% duty on Chinese-origin rigs, triggering $100M+ invoices.

What are the immediate effects of US Bitcoin miner tariffs?
US Bitcoin miner tariffs are squeezing margins by imposing retrospective duties on equipment identified as Chinese-origin, with invoices exceeding $100 million for some public firms. Miners face higher operating costs, impaired cash flow and potential write-downs that could reduce new deployment and delay expansion plans.
How large are the reported tariff liabilities?
Public filings and industry reporting indicate CleanSpark and IREN face exposures in the $100M–$185M range, based on CBP invoices and a revised White House tariff schedule. The duty rate cited is effectively 57.6% on rigs deemed Chinese-origin, magnifying replacement and compliance costs for affected fleets.

Higher capital costs reduce miner profitability and slow capacity growth. Transaction fees have slipped below 1% of block rewards, meaning miners rely mainly on block subsidies and efficient, low-cost operations to remain viable. Tariff shocks therefore heighten insolvency risk for leveraged operators.
July production data showed IREN and Mara Holdings each mined >700 BTC, while CleanSpark and Cango produced >600 BTC. Those outputs provide short-term revenue buffers but may not offset large, unexpected tariff liabilities if firms must absorb duties retroactively.
Polkadot established Polkadot Capital Group in the Cayman Islands to accelerate institutional engagement across DeFi, staking and tokenized real-world assets. The move responds to growing demand from asset managers and is timed with more constructive regulatory signals in the United States.
The group aims to demonstrate enterprise-grade use cases for decentralized finance, staking programs and real-world asset tokenization, helping traditional finance participants evaluate custody, compliance and asset-management integrations on Polkadot.
