Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The rapid rise in U.S. tariffs and the subsequent trade frictions in spring 2025 are having a major impact on the electrical and electronics sector, with semiconductors, display panels, and rare-earth metals (essential for batteries and motors) subject to steep duties. Consumer electronics brands face profit erosion, as competitive markets limit their ability to pass costs to buyers. Industrial electronics manufacturers, meanwhile, grapple with delayed projects due to shortages of tariff-impacted components like printed circuit boards. Companies are responding by relocating assembly to tariff-exempt countries, increasing inventory buffers, and redesigning products to reduce dependency on restricted materials.
