U.S. Semiconductor Tariff Bill Takes Shape, Prompting Seoul to Act

Key Takeaways

The U.S. is implementing a tariff regime linked to semiconductor production, pressuring companies to invest locally.
A recent Taiwan agreement involves $500 billion in semiconductor investment, becoming a benchmark for South Korea.
Korea’s semiconductor industry, vital for exports, faces challenges if it fails to meet U.S. expectations amid increasing tariffs.

U.S. Tariff Pressure on Semiconductor Industry

U.S. Commerce Secretary Howard Lutnick’s recent statements highlight Washington’s evolving semiconductor tariff strategy. Following a semiconductor agreement with Taiwan, U.S. officials have made it clear that tariffs are no longer hypothetical. During a groundbreaking ceremony for Micron Technology, Lutnick asserted that companies must either produce memory chips in the U.S. or face a 100 percent tariff.

The U.S.-Taiwan agreement, announced on January 15, includes Taiwan’s commitment to invest $500 billion in semiconductors, with TSMC pledging $250 billion. In exchange, the U.S. has granted a tariff-free semiconductor quota, encouraging domestic production. This deal sets a high benchmark for other major exporters, particularly South Korea.

Korea’s government and chipmakers are concerned about the implications of the Taiwan deal. A clause from the Korea-U.S. tariff negotiation states that Korea should not receive less favorable treatment than countries with larger semiconductor trade with the U.S., which includes Taiwan. Currently, Samsung Electronics and SK hynix have announced U.S. investments totaling around $41 billion, significantly less than Taiwan’s commitment. This difference may pressure Korea to enhance its investment commitments to avoid punitive tariffs.

In response to these developments, the presidential office has emphasized the need for ongoing consultations to safeguard Korean firms, adhering to the principle of non-discrimination. However, solely defensive strategies pose risks. With rising semiconductor demand in the U.S., Washington may face limitations in enforcing broad tariff increases.

Semiconductors comprise about 30 percent of Korea’s exports and represent its second-largest export category to the U.S. As other sectors like petrochemicals and steel diminish against Chinese competition, semiconductors remain Korea’s crucial global asset. If Seoul does not negotiate effectively and allows itself to be dictated by U.S. tariffs and demands, it could face severe economic consequences in the future.
