US Shifts Legal Strategy to Maintain China Tariffs After Supreme Court Setback

The landscape of American trade policy has entered a period of rapid legal recalibration following a landmark Supreme Court decision that stripped the executive branch of its primary tariff-imposing mechanism. By striking down the use of the International Emergency Economic Powers Act (IEEPA) for broad trade levies, the Court has forced the White House to seek alternative statutory authority to maintain its protectionist agenda. US Trade Representative Jamieson Greer’s recent confirmation that the administration will hold China tariffs steady at 35 to 50 percent signals a tactical shift toward Section 122 of the Trade Act of 1974, a move designed to project stability to global markets while preserving leverage for upcoming diplomatic negotiations.

This transition from IEEPA to Section 122 represents a significant pivot for RegTech and trade compliance departments. While IEEPA granted the President sweeping authority during declared national emergencies, Section 122 is more narrowly tailored to address balance-of-payments deficits. The administration’s decision to push the Section 122 limit to its 15 percent maximum for global tariffs—after initially proposing 10 percent—suggests an aggressive interpretation of trade law intended to bypass the judicial constraints recently imposed. For legal professionals, the core of the issue lies in whether the administration can successfully argue that current economic conditions constitute the specific type of monetary emergency required by the 1974 Act.

The timing of this announcement is strategically aligned with the upcoming summit between President Donald Trump and President Xi Jinping. By maintaining the current tariff levels rather than escalating further, Greer is signaling a desire for "continuity" and adherence to previous de-escalation agreements. This provides a predictable, albeit high, baseline for the bilateral talks. However, the underlying volatility remains high; the administration's reliance on social media to announce rate hikes from 10 to 15 percent creates a challenging environment for logistics and supply chain software that must account for sudden regulatory shifts. Companies must now prepare for a new wave of presidential proclamations that will codify these changes into the federal register.
