US Tariffs: New Section 301 Framework Replaces IEEPA Regime

The US Supreme Court has invalidated the original IEEPA tariff regime, triggering a wave of refunds for affected importers while simultaneously introducing fresh tariff pressures. The Trump administration has swiftly moved to implement a new Section 301 tariff framework covering imports from 60 economies, creating a complex landscape for global supply chain operators. This represents a structural shift in US trade policy rather than a temporary adjustment, with implications spanning multiple sectors and geographies.

The dual nature of this development, refunds offsetting new duties, creates both opportunities and uncertainties for importers. Companies must navigate both the administrative process of claiming refunds on past overpayments while simultaneously evaluating the cost impact of the new tariff schedule. The breadth of the new framework (60 target economies) suggests wide-reaching consequences for diversified supply chains sourcing from Asia, Europe, and other regions.

For supply chain professionals, this signals the need for urgent tariff strategy reassessment, including sourcing diversification analysis, landed cost recalculation, and potential pricing negotiations with vendors and customers. The transition period presents both a window for refund recovery and a deadline for operational adaptation to the new tariff environment.
