US tech decoupling from China faces steep costs as domestic manufacturing lags

Rajat Bhageria built his robotics company on a simple principle: find the best parts at the lowest price. Seven years into running Chef Robotics in San Francisco, he's learning that principle no longer applies. The robot arms his company sells to food manufacturers—machines that automate the assembly of ready-made meals—have always relied on Chinese components. China's ability to manufacture parts cheaply and at enormous scale made it the obvious choice. But the Trump administration has begun systematically banning the use of Chinese technology in the United States, and Bhageria now faces a question his investors and customers keep asking: why is he still buying from China at all?

The restrictions are expanding rapidly. In July, the Federal Communications Commission added power inverters and advanced robotics to its list of prohibited foreign-made goods. The US has enacted a 100% tariff on Chinese electric vehicles, similar tariffs on drones, and banned new drone models outright. Ford, one of America's largest automakers, drew criticism from the Trump administration this month for using Chinese electric car batteries. The stated goal is clear: protect national security by reducing dependence on Chinese supply chains and incentivizing domestic manufacturing. But the practical effect is creating a bind that American companies are struggling to escape.

When Bhageria tried to shift production of his robot arms' end-effectors—the plastic grabbers that do the actual work—to domestic suppliers last year, he hit a wall. The cost would be prohibitively high. Many American machine shops simply told him they couldn't do the work. "It's actually been a much harder process than we had initially hoped," he said. The components he needs aren't yet on the banned list, but he's bracing for that to change. "You can imagine what's the next shoe to drop, right? Like, the next thing might be fixed robot arms."

The challenge Bhageria faces is structural. Decades of outsourcing have left American manufacturers without the capacity to meet demand for precision components at competitive prices. Michael Murray, chief executive of Kopin Corporation, which makes optical components for military drones, spent more than two years relocating micro display screen manufacturing from China to the United States. The result: production costs rose by as much as 25%. The Department of Defense helped offset those expenses, but the math is brutal. China can produce more micro displays in a single week than the US produces in an entire year. "We don't have the volumes to get the costs down as much as the rest of the market," Murray said.

Gavin Kenneally, whose company Ghost Robotics makes industrial and military robot dogs, is hunting for new sources of rare earth metals—materials where China holds near-total global dominance. He's already moved motor production to South Korea and sources neodymium magnets from Europe, but the raw material still comes from China. A government ban on those materials takes effect in January. "It's an extremely difficult supply chain problem to solve in the short term," Kenneally said. He believes the bans will eventually stimulate domestic production, but the transition period is brutal.

The ripple effects are spreading beyond robotics companies. At the University of Illinois Urbana-Champaign, engineering professor Sayan Mitra teaches courses that rely on Chinese-made robotic arms, drones, humanoids and vehicles. Replacing Chinese humanoids with American alternatives could cost ten times more. Some drone options may not exist domestically at all. "It's like we are trying to do surgery on a patient that is already on their feet," Mitra said. If the restrictions expand unpredictably, he warned, the entire effort to build a domestic robotics research ecosystem could derail.

Ben Armstrong, executive director of MIT's Industrial Performance Center, frames the problem plainly: "A lot of our digital lives are built on the infrastructure of foreign-made components and goods assembled abroad, and that's not going to change anytime soon. We just don't know how to make them in the US. So, there will be a learning curve, and during that learning curve process, the price will be high." That learning curve will be paid for by American companies, universities, and consumers. Even everyday goods are caught in the crosshairs—the FCC ban on mobile robots includes robot vacuums, pool cleaners, and lawn mowers, the vast majority of which are made in China. Jitesh Ubrani, a tech analyst at IDC, said moving that manufacturing to the US would be extremely expensive. "Long-term, sure, that could happen. But that'll probably be very expensive, and so the US consumers end up just paying a whole lot more."

Saman Farid, founder of the industry coalition Robots for America, worries that restrictions are expanding faster than alternatives can be created. "In the time that it takes an American company to build their first prototype, a Chinese company may already be on version three," he said. The decoupling from China is happening, but the domestic infrastructure to replace what's being cut off is not yet in place. The question now is whether American companies and research institutions can survive the gap.
