The doubling of tariffs on steel and aluminum causes global upheaval.

The U.S. government officially increased tariffs on imported steel and aluminum products from 25% to 50% starting June 4, which quickly caused a global uproar. Several major economies have responded strongly, criticizing the move as "economic self-harm" and warning of retaliatory measures to protect their domestic industries.

International Condemnation, U.S. Allies Speak First

According to the Wall Street Journal, this tariff increase has prompted South Korea’s Ministry of Trade to hold an emergency meeting on the first day of the Asian market opening to discuss potential impacts. Canada’s United Steelworkers have called the U.S. move a "direct attack" on Canadian industry and workers, potentially leading to significant job losses. The European Commission also expressed regret, stating the decision "increases global economic uncertainty" and is preparing countermeasures to implement by July 14.

The German Steel Federation pointed out that the U.S. actions not only weaken the export capability of German companies but will also force suppliers from other countries to shift to the European market, increasing regional competition and pressure. Australian Prime Minister Albanese publicly criticized the tariff doubling as "harmful to its own economy."

Strong Reactions from Asian Exporting Countries

South Korea stated that the U.S. is a crucial market for its steel exports, accounting for over 13% in 2024 alone. The South Korean Ministry of Trade, Industry and Energy expressed that it will closely monitor U.S. policies and actively negotiate to mitigate the impact on domestic steel companies. India also faces pressure. According to economic think tanks, the country’s exports of related products to the U.S. totaled $4.56 billion in the 2025 fiscal year, and the new tariff policy will severely squeeze the profit margins of domestic producers.

Rising Domestic Skepticism in the U.S.

Although the U.S. claims this move aims to "revitalize manufacturing," experts broadly believe its effects will be counterproductive. Boston Consulting Group estimates that the previously effective 25% tariff alone resulted in hundreds of billions of dollars in additional costs for U.S. companies. With tariffs now doubled, industries such as automotive, construction, drilling, and beverage packaging will face skyrocketing raw material costs, sharply increasing corporate pressure.

William Oplinger, CEO of American aluminum giant Alcoa, stated bluntly that this policy could lead to the loss of 100,000 jobs, with the aluminum industry alone losing 20,000 positions.

Economic Goals and Reality Drift Apart

Experts point out that blindly raising tariffs without effective industrial alternatives or transitional policies not only fails to effectively boost domestic production but exacerbates supply chain costs and market uncertainty. Some scholars criticize such policies as erratic and lacking strategic logic, potentially undermining the original goal of "protecting jobs."

In summary, this latest round of U.S. tariff doubling not only failed to gain domestic support but also sparked widespread dissatisfaction and concern on the international stage and might become the trigger for the next round of global trade tensions. Whether the U.S. will further adjust its policy stance in the coming months remains to be seen.
