US Tariffs & Korea’s Strategy: Navigating Trade Pressure & Geopolitical Shifts

Endless US Tariff Pressure and Korea’s Response Strategy

The U.S. Supreme Court’s recent decision striking down President Trump’s International Emergency Economic Powers Act (IEEPA) tariffs has not signaled a retreat from protectionist trade policies. Instead, the administration has quickly moved to implement alternative measures, raising new concerns for exporting nations like South Korea. This analysis examines the implications of the ruling and potential responses from South Korea.

Weakening the WTO System and the Rise of Selective Economic Cooperation

According to Jeong Cheol, Director of the Korea Economic Research Institute, the international economic order is shifting from a rules-based system to one driven by power dynamics and bilateral deals. The multilateral trade system, traditionally centered on the World Trade Organization (WTO), is weakening, with trade and security interests increasingly intertwined. Economic cooperation is now often determined by sector or issue, rather than broad economic logic and manufacturing landscapes are being reshaped by geopolitical alliances.

Global manufacturing competition is evolving beyond simply minimizing production costs. Companies must now consider tariffs, logistics, insurance, and risks associated with each country’s industrial policies – a “total cost + risk” calculation. South Korea, heavily reliant on trade, must adapt to this new environment.

Competition is particularly intense in strategic industries like semiconductors, batteries, and artificial intelligence (AI), where technological advancement is inextricably linked to manufacturing capabilities. Redesigning production bases, diversifying supply chains for key minerals, and actively participating in setting industry standards are essential for survival. Overcoming trade barriers requires strengthening corporate competitiveness.

Indiscriminate Tariff Offensive Against Traditional Allies

Participants at a recent trade forum agreed that the Trump administration’s actions signal a new international order centered on geopolitics. One participant noted that extending tariff offensives to close allies like Canada, Mexico, Korea, and Japan demonstrates a loss of confidence in U.S. Global leadership. A key first step is to analyze the strategic implications of these changes, not just defend against immediate tariffs.

Following the Supreme Court ruling, the White House announced it would utilize Section 122 of the Trade Act of 1974 to impose a 10% global tariff for 150 days, potentially increasing to 15% as stated by President Trump. However, experts have questioned the legal basis for using Section 122, citing the absence of a balance of payments problem. The administration also has the option of invoking Section 338 of the Tariff Act of 1930, Section 232 of the Trade Expansion Act of 1962, or Section 301 of the Trade Act of 1974, though these would require investigative reviews.

Adapting to a New Trade Order

Many attendees agreed that a response strategy must acknowledge that tariffs are now a constant factor. One participant stated that a second Trump term would likely be even more determined to reshape the trade paradigm, signaling the end of the “Most Favored Nation” principle. Another participant pointed out that tariff revenues were previously generating $30 billion monthly, making a complete reversal unlikely with a change in administration.

Participants also suggested that any unavoidable investment commitments in the U.S., such as the proposed $350 billion, should be leveraged to secure favorable terms, such as exemptions for production facilities and raw materials, similar to those granted to Taiwan.

Pragmatism and Korea-US Cooperation

The require for a pragmatic approach was emphasized, particularly regarding commercial rationality in U.S. Investments. While the government has emphasized commercial viability, concerns were raised about whether such rationality will be guaranteed in practice.

Expanding cooperation with the U.S. Through investment was also seen as a way to counter China’s influence. Korea relies heavily on China for intermediate goods, particularly in strategic sectors like semiconductors and batteries. Investment in the U.S. Market, viewed as strategically valuable, should be considered with a long-term perspective.

Addressing Non-Tariff Barriers

Caution was expressed regarding the potential invocation of Article 301 of the Trade Act, which could be used to address a wide range of trade concerns, including overproduction, subsidies, and environmental regulations. Participants emphasized the need for a logical defense against potential non-tariff barriers, such as explaining unavoidable overproduction due to Chinese supply.

The potential impact of large-scale U.S. Investments on the exchange rate was also highlighted, requiring careful financial management.

Finally, participants agreed on the importance of accelerating preparations for joining the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) and strengthening legal lobbying efforts in the U.S. Chairman Hong Seok-hyun emphasized the need for a systemic approach, bringing together experts from various fields to develop comprehensive countermeasures.
