Former President Donald Trump has proposed a 100% tariff on imported semiconductors, with a significant exemption for companies manufacturing in or committed to building facilities in the United States. This policy aims to incentivize domestic chip production, benefiting tech giants like Amazon, Google, and Microsoft, and companies like Apple that have pledged substantial US investments. This aligns with Trump's broader strategy to bring manufacturing back to the US, building on the $52.7 billion CHIPS and Science Act of 2022, which has already spurred over $30 billion in private investments across 23 projects.

Despite advocating for these tariffs, Trump has previously criticized the CHIPS Act, calling it a "horrible thing" and suggesting its $52.7 billion in subsidies should instead be used to pay down national debt. The Biden administration, under the CHIPS Act, awarded significant funds, including $4.745 billion to Samsung, $7.86 billion to Intel, $6.6 billion to TSMC, and $6.1 billion to Micron. While Trump argues that companies like TSMC "didn’t need money" from the subsidies, he acknowledges that tariffs could serve as a powerful incentive for them to invest domestically.

However, these proposed tariffs introduce a contradiction. While they aim to boost US manufacturing, they could simultaneously lead to increased consumer prices for products reliant on semiconductors. Analysts warn that the higher costs associated with tariffs are typically passed on to consumers. Furthermore, while the tariffs are contingent on companies like TSMC investing billions in the US, there are concerns that the exemptions could become a "giveaway to TSMC" without proper oversight, potentially undermining the integrity of the tariff and rebate system.

The policy highlights the US's continued reliance on global supply chains, even as it seeks to bolster domestic production. The exemption for Big Tech, coming after the US-Taiwan trade deal, underscores the difficulty of weaning the US off imports. Washington seems to acknowledge that achieving a robust homegrown chip sector requires integrating major players like TSMC, potentially through "sweetheart deals" for US multinationals.
