Key Points

TSMC has raised concerns that proposed US tariffs could destabilize its massive $165 billion semiconductor investment in Arizona. The chipmaker warned that import restrictions might reduce demand for end products containing semiconductors, impacting its Phoenix facilities. With one fab already producing chips and two more under construction, TSMC emphasized the risks to US tech competitiveness. The company also outlined plans for an additional $100 billion investment in Arizona-based wafer fabs and R&D centers.

TSMC warns US tariffs could derail USD 165 billion Arizona investment

TSMC cautions US tariffs could jeopardize its $165B Arizona semiconductor plants, citing reduced chip demand and project uncertainties.

"New import restrictions could jeopardize current US leadership in the competitive technology industry – TSMC letter to US Commerce Dept"

Taipei, May 24

Taiwan Semiconductor Manufacturing Company (TSMC) has cautioned the US government that imposing tariffs on Taiwanese semiconductors could undermine its significant investment plans in Arizona, Focus Taiwan reported on Friday.

The company's USD 165 billion investment aims to build advanced semiconductor fabrication facilities in the state, but TSMC warned that tariffs could reduce demand for chips and jeopardize the project's success.

"New import restrictions could jeopardize current US leadership in the competitive technology industry and create uncertainties for many committed semiconductor capital projects in the US, including TSMC Arizona's significant investment plan in Phoenix," the chipmaker wrote in a letter to the US Department of Commerce.

TSMC argued that tariffs would increase costs for end consumers, leading to lower demand for products containing semiconductors, reported Focus Taiwan.

According to Focus Taiwan, the country's government and companies has always been unwilling to raise any voice against the "the Donald Trump administration's chaotic tariff rollout but the TSMC letter made the case that going through with them would have negative consequences."

TSMC letter stated that any import measures adopted by the trump's administration "should not create uncertainties for existing semiconductor investments," referring to its huge investments in Arizona.

In Arizona, TSMC has currently invested USD 65 billion to build three advanced wafer fabs in Arizona. "The first one has begun mass-producing chips, construction of the second fab is nearly complete, and a groundbreaking ceremony was held for the third fab last month," Focus Taiwan reported.

In March the company also planned to invest USD 100 billion in Arizona Project over next few years, to set up three more wafer fabs, two packaging and testing plants and one research and development center.

In the letter, TSMC stated that "tariffs that raise the cost of end consumer products will lower demand for such products and the semiconductor components they contain." It further added, "Therefore, TSMC respectfully requests that any remedial import measures imposed resulting from this investigation not extend to downstream end products and semi-finished products containing semiconductors."

Earlier this month, TSMC reported a significant rise in revenue figures for April 2025, attributed to surge in demand for advanced semiconductors.

Interesting development! While US-Taiwan relations are complex, India should watch this closely. We're building our own semiconductor ecosystem and such tariff wars could affect global supply chains. Maybe an opportunity for India to attract some of these investments if US becomes less attractive? 🤔

TSMC makes valid points - tariffs will ultimately hurt consumers worldwide. In India, we've seen how import duties on electronics make gadgets more expensive. The US should think carefully before disrupting such critical global supply chains. Our mobile phone prices are high enough already!

This shows why India's semiconductor mission is so important. We can't rely on these geopolitical tensions between US-China-Taiwan. Hope our government accelerates the Dholera semiconductor plant and other projects. Atmanirbhar Bharat in chips is the need of the hour!

While I understand TSMC's concerns, the US has every right to protect its industries. India should also have strategic tariffs where needed. But we must balance - too much protectionism can backfire. Our PLI schemes seem to be working better than blunt tariffs.

The semiconductor industry is too interconnected for tariffs. What happens in Arizona affects prices in Delhi. Hope both sides find a solution - the world needs more chips, not trade wars. Maybe India can play mediator role given our good relations with both US and Taiwan?
