Abstract: Shortly after beginning his second presidential term, U.S. President Donald Trump launched the most ambitious tariff campaign in nearly a century, widely referred to as the Trump 2.0 tariff regime, which has triggered subsequent retaliatory measures by major trading partners. The frequency of announcements, exemptions, suspensions, and legal substitutions generated unprecedented chaos and profound disruptions to global economy and global supply chains. This paper provides a structured review of the Trump 2.0 tariff regime and its implications for global supply chains. It synthesizes expert perspectives on the economic consequences of the tariffs and examines their impact on freight transportation, manufacturing, consumer spending, and firm-level strategic responses. The paper further reviews a range of supply chain adaptation strategies, including supply chain adaptation, tariff tipping-point analysis, strategic contract management, and circular economy practices. Seven general principles are proposed in responding to Trump tariff. To illustrate these strategic responses, two case studies are presented: (1) Hakkai Inc. of Japan and its experiences and strategies facing the tariff; and (2) Taiwan Semiconductor Manufacturing Company (TSMC) and the global semiconductor industry facing the tariffs. These cases demonstrate how firms and their supply chains have responded to an increasingly uncertain and politically driven trade environment. The findings provide practical insights for business owners, procurement professionals, supply chain managers, and corporate strategy teams seeking to enhance supply chain resilience under tariff-induced disruptions. The cases offer guidance for organizations developing strategies to compete in an increasingly fragmented global production system shaped by geopolitical tensions and trade policy uncertainty.
