USTR Greer Affirms Bilateral Trade Pacts Amid Supreme Court Tariff Reversal

The recent US Supreme Court ruling against the Trump administration's broad tariff-imposing authority initially sent shockwaves through the global logistics and procurement sectors. For years, supply chain strategies have been built around the expectation of aggressive, executive-led trade barriers. However, US Trade Representative Jamieson Greer has moved quickly to provide a 'firewall' between the administration's broad executive orders and its negotiated bilateral treaties. By clarifying that individual trade deals remain on track, the USTR is signaling to the market that while the mechanism for unilateral tariffs may be legally compromised, the framework of negotiated international trade remains the administration's primary tool for economic policy.

This distinction is vital for businesses that have spent the last several years diversifying their sourcing strategies to align with US trade priorities. In the immediate aftermath of the court's decision, there was significant concern that the legal basis for various trade incentives and protections might collapse, leading to a chaotic 'reset' of import duties. Greer’s intervention suggests that the administration views its bilateral agreements—such as those with Japan, South Korea, or the USMCA framework—as legally distinct from the broad executive actions that the Supreme Court scrutinized. For logistics professionals, this means that 'friend-shoring' initiatives backed by formal treaties are likely to remain the most stable path forward.

However, US Trade Representative Jamieson Greer has moved quickly to provide a 'firewall' between the administration's broad executive orders and its negotiated bilateral treaties.

From an industry context, this development highlights a shift from blanket protectionism to a more granular, treaty-based approach. If the judiciary continues to curtail the President's ability to impose tariffs via Section 232 or Section 301 executive actions, the USTR will likely pivot toward more intensive, country-by-country negotiations. This will inevitably increase the complexity of trade compliance, as duty rates and regulatory requirements become increasingly fragmented across different trade corridors. Procurement officers must now prioritize 'Country of Origin' (COO) data with even greater rigor, as the legal safety of a shipment may depend entirely on whether it falls under a specific bilateral pact or a now-contested executive order.

Expert perspectives suggest that the Supreme Court's ruling acts as a check on executive power but does not necessarily signal a return to pre-2016 trade norms. Instead, it forces the administration to seek more permanent, legislative, or treaty-based solutions to achieve its 'America First' objectives. The logistics sector should prepare for a period of 'legal layering,' where existing tariffs are challenged in lower courts while the USTR simultaneously rushes to codify those same tariffs into formal bilateral agreements that are harder to overturn judicially.

Looking ahead, the stability of the US trade environment will depend on how quickly the administration can transition its trade goals from executive mandates into these durable bilateral frameworks. While Greer’s comments provide a temporary floor for market sentiment, the long-term impact will be felt in the increased demand for trade legal counsel and automated compliance software. Companies that can quickly pivot their supply chains to favor corridors protected by formal bilateral treaties will be best positioned to weather the ongoing legal volatility in Washington.
