KUALA LUMPUR, 30 September 2025 — The U.S.-ASEAN Business Council has warned that blanket U.S. tariffs on Malaysian semiconductor exports could backfire, disrupting global chip supply and harming U.S. industries that depend on Malaysian components.
Malaysia plays a crucial role in the international semiconductor ecosystem, particularly in testing, assembly, and packaging (TAP) operations. Many chips destined for U.S. auto and electronics manufacturers pass through Malaysian facilities. Imposing sweeping tariffs, the council argues, could trigger ripple effects that delay production, raise costs, and unsettle manufacturing networks.
The Stakes: Malaysia’s Export Footprint & U.S. Dependence
Malaysia exported around RM52.11 billion worth of semiconductors and integrated circuits to the U.S. in the prior year. Many of these chips are produced by U.S.-based firms operating locally—such as Intel, Broadcom, and Micron, blurring the line between domestic and foreign value creation.
The council notes that some estimates place Malaysia’s share of U.S.-consumed semiconductor chips at as high as 15 %, especially in automotive applications. Disrupting that flow could hinder U.S. assembly plants, vehicle production lines, and other downstream electronics sectors.
Exemptions & Uncertainty
Despite recent threats, Malaysian officials point out that semiconductors and pharmaceuticals were already exempted from the 19 % U.S. tariff imposed earlier this year. However, these exemptions are under review, and expanding tariff coverage is not off the table.
Industry observers caution that if exemptions are removed or altered, Malaysian firms could see a sudden spike in costs—or be compelled to shift production to safer jurisdictions.
Risks & Opportunities for Stakeholders
For Malaysian tech firms, the spectre of tariffs underscores the need to hedge and diversify. Companies reliant on U.S. markets may accelerate investment in value-added capabilities or pursue alternative markets.
For U.S. manufacturers, any disruption to chip imports—even temporarily—would add to component constraints, potentially eroding margins or delaying product rollouts.
For investors, the uncertainty suggests elevated volatility in sectors tied to semiconductors, including EMS, test and measurement equipment, and chip packaging operations. Timing, regulatory clarity, and a firm’s share of U.S. exposure will be vital differentiators.
