US 337 Probe Targets 20 Firms, Threatening Taiwan Power Components

The United States International Trade Commission (USITC) voted on the 10th to initiate an investigation under Section 337 of the Tariff Act into "certain vertical power transmission systems, components thereof, and computing equipment containing the same." The investigation list covers 20 entities, including companies from Taiwan, Germany, China, and the United States. The commission explicitly stated that while the investigative procedure has been initiated, no decision has been made on the merits of the case, nor has any imminent imposition of tariffs been announced.

This move comes as US-China trade friction intensifies. In recent years, the United States has repeatedly used Section 337 of the Tariff Act as a basis to launch investigations or impose tariffs on high-tech products deemed to pose potential risks to national security. Section 337 allows the United States to levy tariffs on products alleged to infringe upon U.S. patents or engage in unfair trade practices, without the need for a formal trade agreement. For Taiwan, this is not only a test for its high-tech industry, but also concerns its positioning within the global supply chain.

Taiwan boasts several globally competitive enterprises in the fields of power transmission and computing equipment. These companies not only provide critical components for domestic power system upgrades but also contribute technologies to the digitalization and intellectualization of global power grids. Should the United States ultimately decide to impose tariffs, it will directly impact the export costs and market share of these enterprises. More importantly, the operational costs of Taiwanese companies in the U.S. market will rise, potentially forcing them to accelerate the search for alternative markets or adjust their product structures to maintain competitiveness.

The Taiwanese government and industrial sector have already begun making preparatory measures in response to the investigation. The Ministry of Economic Affairs stated that it will strengthen dialogue with the U.S. side to ensure that Taiwanese companies can fully express their positions during the investigative process, while simultaneously employing a diversified market strategy to reduce reliance on a single market. Industry representatives have urged the United States to provide sufficient time and transparency during the investigation to prevent sudden trade barriers from disrupting the supply chain. If the United States ultimately implements tariffs, Taiwan may also consider utilizing the dispute settlement mechanisms within free trade agreements (FTAs) to seek legal avenues for safeguarding corporate rights and interests.

From a broader perspective, this investigation once again highlights the role of the United States as a "threshold setter" in the global high-tech supply chain. By utilizing Section 337, the United States intends to restrict the cross-border flow of specific technologies—particularly targeting competitors such as China—without directly participating in trade agreements. As an important node in the global semiconductor and high-tech industries, Taiwan will inevitably face a more complex international trade environment if it is included in the investigation. Taiwanese enterprises must strike a balance between technological innovation and market diversification in order to maintain resilience amid this international competition.
