Bitcoin mining operations in the United States are absorbing a 47% increase in implementation costs, on top of Section 232 tariffs on steel, aluminum, and copper, as well as the existing 21.6% tariff on ASIC miners in Southeast Asia, giving it a competitive advantage over mining operations in Kazakhstan, Russia, and other tariff-exempt regions.
The Article 232 Declaration, signed on April 2, increased tariffs to 50 percent for products made solely from steel, aluminum and copper, and to 25 percent for derivative products containing significant amounts of metals. The mining rigs qualify as derivative products, adding 25 per cent to the total tariff for each unit, in addition to the existing Southeast Asia ASIC tariff of 21.6 per cent. The tariffs went into effect on April 6th. This means that all hardware ordered after that date will be subject to a combined charge. Large miners such as Marathon Digital, Riot Platforms and CleanSpark, which were stockpiling before the tariffs were implemented, have been partially isolated for now, but future hardware upgrade cycles will be relatively expensive compared to their offshore competitors.
The United States controls about 38 percent of the world’s Bitcoin hashrate. This position, built over four years after China banned mining in 2021, could now begin to be eroded by tariff pressure rather than direct bans. A U.S. miner who replaces their hardware with an S21 XP will pay approximately 47% more than a competitor in Kazakhstan or Russia who buys the same machine with zero customs duties. Hashprice, the daily revenue per TeraHash, is already near historic lows. Miners will not be able to absorb the 47% increase in hardware costs without raising capital, scaling back, or waiting for Bitcoin to rise.
What miners are doing in response
Large publicly traded mining companies with pre-tariff inventories continue to operate without immediate impact. Bitmain opened its first assembly line in the U.S. in January 2026, and MicroBT has been operating a factory since 2023, but these are only a portion of its total production. U.S.-assembled rigs still face tariffs on aluminum and copper components. Sens. Cassidy and Lummis introduced the American Mining Act in late March, which would create federal subsidies and tax incentives for domestic miners, but a vote date has not been set.
What the impact of tariffs means for network security
If the hardware cost differential persists over two to three upgrade cycles, meaningful hash rates could shift from the US to tariff-free jurisdictions. This would reduce the US share in Bitcoin’s security model and concentrate hashrate in countries with weaker property rights and less transparent regulation. With the US as an anchor, the network surpassed 1,000 exahash per second in early 2026, but maintaining that anchor becomes more difficult with each tariff cycle, making domestic expansion more expensive than offshore alternatives.
