President Donald Trump has suffered a significant legal setback in his signature trade policy, but the battle over tariffs is far from over. The Supreme Court ruled that Trump exceeded his authority by invoking the International Emergency Economic Powers Act (IEEPA) to impose sweeping "reciprocal" tariffs on America's trading partners. This decision struck down the cornerstone of his "Liberation Day" tariff strategy that targeted nearly every country (Articles 1, 14). However, Trump moved with remarkable speed to implement Plan B. Within hours of the Supreme Court ruling, the administration invoked Section 301 of the 1974 Trade Act to impose a new 10% baseline global tariff, which took effect on February 24, 2026 (Articles 8, 9). This tariff carries a 150-day duration and requires no congressional approval under existing law.
Several critical patterns have emerged that signal what's coming next: **Escalatory Rhetoric**: Trump immediately warned countries not to "play games" with the Supreme Court decision and threatened that nations attempting to renegotiate deals would face "much higher" tariffs (Articles 11, 16, 19). He publicly stated his desire to raise the global baseline from 10% to 15%, signaling his intention to push tariff levels higher (Articles 6, 16). **Alternative Legal Mechanisms**: US Trade Representative Jamieson Greer outlined the administration's strategy to use Section 301 investigations, which allow for "public investigations" where citizens can submit evidence of unfair trade practices (Article 6). This approach provides a more legally defensible framework than the emergency powers that were struck down. **International Uncertainty**: The EU has effectively paused implementation of its trade deal with the US, citing lack of "legal certainty" about whether Washington's tariffs comply with the law (Articles 7, 19). Irish MEP Barry Andrews noted that India, Japan, and Taiwan are similarly "slow-walking" trade agreements with the US (Article 7). This widespread hesitation suggests trading partners are preparing for continued instability. **Market Reactions**: Base metals markets, particularly copper, showed volatility around the Supreme Court decision, with Chinese traders initially cheering the prospect of lower US levies before demand patterns normalized (Articles 3, 10). This indicates markets remain highly sensitive to tariff policy shifts. **Institutional Resilience**: Despite claims of democratic decline, analyses emphasize that American checks and balances remain functional, with midterm elections approaching in November 2026 (Articles 4, 5). This suggests ongoing political constraints on Trump's authority.
### 1. Tariffs Will Rise to 15% or Higher for Most Countries The 10% baseline tariff currently in effect is explicitly temporary. US Trade Representative Greer has already announced plans to raise tariffs to 15% "where appropriate" through presidential proclamation (Article 6). Trump's public statements demanding 15% as a new global baseline (Article 16) indicate this increase is imminent. **Timeline**: Within 2-4 weeks, likely before or during the State of the Union address period. **Reasoning**: The administration views this as necessary to "recreate the policy" developed over the past year and maintain leverage in trade negotiations (Article 6). Trump's aggressive rhetoric about countries "playing games" suggests he will use higher tariffs as punishment for any attempts to renegotiate existing deals. ### 2. Section 301 Investigations Will Proliferate The administration will launch dozens of Section 301 investigations targeting specific countries and industries. This mechanism allows Trump to impose retaliatory tariffs of varying levels based on documented "unfair trade practices" without relying on emergency powers (Article 6). **Timeline**: Within 1-2 months, with investigations announced on a rolling basis. **Reasoning**: Section 301 provides legal cover that IEEPA lacked. By framing tariffs as responses to specific unfair practices rather than blanket emergency measures, the administration can build a more defensible legal case. Greer explicitly stated the administration is "preparing for foreign countries to sue," indicating they've designed this strategy to withstand judicial scrutiny (Article 6). ### 3. Congressional Action Will Stall Until After Midterms Despite Democratic calls for tariff refunds—such as Senator Gillibrand's demand for $130 billion in reimbursements (Article 2)—Congress will not pass meaningful legislation curtailing tariff authority before the November 2026 midterm elections. **Timeline**: 8-9 months (through November 2026). **Reasoning**: The Supreme Court ruling affirmed that existing statutes delegate substantial tariff authority to the president (Article 14). Changing these laws requires legislation that would face Republican opposition in at least one chamber. With midterms approaching, neither party wants to risk electoral consequences of being seen as either too protectionist or too soft on trade. ### 4. EU-US Trade Deal Remains Frozen The European Union will not ratify its trade agreement with the United States during the 150-day period of the current tariff regime, and possibly much longer (Article 7). **Timeline**: At least 5-6 months. **Reasoning**: The EU Parliament has already paused implementation, and MEP Andrews articulated the core problem: without legal certainty about US tariff compliance, Europe cannot proceed (Article 7). The EU's institutional caution and the upcoming Hungarian elections add additional complications. The bloc will wait to see whether Trump's Section 301 approach survives legal challenges before committing to a major trade agreement. ### 5. Supreme Court Will Face Additional Tariff Challenges New legal challenges to the Section 301-based tariffs will reach federal courts within months, potentially returning to the Supreme Court by late 2026 or early 2027. **Timeline**: Initial district court filings within 2-3 months; Supreme Court consideration within 8-12 months. **Reasoning**: Greer acknowledged the administration expects to be sued (Article 6). The CEO who successfully challenged the previous tariffs expressed feeling "validated" by the Supreme Court decision (Article 13), suggesting the business community is emboldened to continue legal action. Justice Gorsuch's unusual solo opinion criticizing his colleagues' "inconsistent application" of legal doctrines (Article 18) hints at potential internal divisions that could affect future rulings.
The Supreme Court setback has not ended Trump's tariff agenda—it has merely redirected it into different legal channels. The administration's rapid pivot to Section 301 authority demonstrates sophisticated contingency planning. While the 10% baseline tariff is currently in place, the trajectory points clearly toward higher rates, more targeted investigations, and continued trade policy uncertainty. International trading partners face a difficult choice: accept Trump's new framework and higher tariff levels, or resist and face even more punitive measures. Most will likely choose the former, calculating that accommodation is preferable to escalation. However, the legal uncertainty noted by the EU (Article 7) will continue to suppress international trade agreements and investment decisions. The real test comes in November 2026, when midterm elections could shift the political landscape. Until then, Trump retains substantial tariff authority under existing statutes, and his demonstrated willingness to push legal boundaries suggests trade barriers will remain a defining feature of US economic policy throughout 2026.
US Trade Representative Greer explicitly announced plans to raise tariffs to 15%, and Trump publicly demanded this level. The administration views this as necessary to maintain trade leverage.
Greer outlined this as the core strategy for legally defensible tariffs. The administration is preparing for legal challenges, indicating this approach is central to their plan.
EU has already paused implementation citing lack of legal certainty. Multiple countries including India, Japan, and Taiwan are similarly delaying agreements.
Administration explicitly expects to be sued. Business community is emboldened by recent Supreme Court victory and has demonstrated willingness to challenge tariffs.
Greer stated tariffs may go 'higher for others,' and Trump threatened countries that 'play games' would face 'much higher' tariffs. This suggests differentiated rates based on compliance.
Senator Gillibrand already demanding $130 billion in refunds, but Republican opposition and divided government make passage unlikely before midterms.
Copper and base metals already showing sensitivity to tariff announcements. Higher and more varied tariff rates will create continued market uncertainty.
Administration's strategy relies on bilateral negotiations. Some countries will likely calculate that accommodation is preferable to escalation and economic uncertainty.
