The collapse of the Trump tariff regime is not an endpoint but the starting line of a new phase. The new rules of the game, however, have changed entirely — shifting from a "social-media bullying" mode to a "procedural-legal" mode. The Trump administration's most damaging weapon — the ability to issue a tweet and immediately impose a tariff to intimidate trading partners — has been taken away by the Supreme Court.
After the Supreme Court ruled 6–3 on February 20, 2026 that the IEEPA tariffs were unlawful, Trump quickly pivoted to Section 122 as a stopgap — but that temporary arrangement can only hold until July 24, 2026. What will the Trump administration face after that? Ten systematic forward projections drawn from a video analysis by Tu Zhuxi (a Bilibili commentator) make up a full forward look at the post-IEEPA tariff regime.
I. Ten Forward Projections
1. Trump Will Absolutely Not Back Down
No matter how great the setbacks, tariffs are Trump's worldview, his political legacy, and his dignity. After the Supreme Court blow and the setback over Iran, the response will be to "double down." He will not admit defeat; he will only look for new tools to push the tariff agenda forward.
2. The "Pre-Cooked" Investigation Trap
All the substitute legal tools (Section 301, Section 232, etc.) require investigation procedures. The Trump administration's investigations are all "pre-cooked" — for every pre-selected country and industry, the conclusion of "yes, add a tariff" is foregone. The investigations are rushed and poorly reasoned, so legal overturning is inevitable. This structural contradiction cannot be solved through administrative means.
3. The Time-Window Pressure
Given the IEEPA precedent, if the new tariffs are struck down again in the final two years of his term, there will be no chance of a comeback. The Trump administration must find a balance between "speed" and "stability" — but that is almost impossible. The real pressure begins after Section 122 expires in July 2026.
4. Tool-Patchwork — The Fragmentation of Tiered Tariffs
The Trump administration can only cobble together a tiered tariff system, with the core tools being:
- Section 301 (country-specific tariffs) — replaces IEEPA's one-on-one threat capability, but requires a USTR investigation and cannot take effect immediately
- Section 232 (industry-specific tariffs) — maintains industry-level tariff coverage on "national security" grounds
- The combination of the two tools can never restore the flexibility and deterrence of IEEPA

5. The Enormous Risk of Judicial Challenge
Rushed action inevitably brings procedural error. The anti-tariff side (importers, consumer brands, free-trade advocates) will go all out against it, putting every error under the spotlight. The IEEPA precedent has laid a legal foundation for the next wave of judicial challenges.
🔑 The Sixth Projection — The Most Critical One
The era of social-media tariff bullying is over. Trump has lost the ability to post a tweet and immediately impose a tariff. As long as the law requires a process, the President cannot arbitrarily threaten or impose tariffs; he must go through procedures step by step. On trade policy, the Trump administration may still be able to cause damage, but it has already entered its lame-duck phase ahead of schedule.
7. The Tariffs on China Can Be Reconstructed
Through patchwork effort, the Trump administration can roughly reconstruct the tariff regime on China — China is one of America's few main competitors and worth the administrative investment. But the reconstructed system will be more fragile and more easily exposed to legal challenge.
8. Countries Will Stand Pat and Watch
Countries that have already signed agreements will not easily reverse course (Trump's appetite for revenge is strong). China should respond to change with constancy, argue on the basis of principle, and apply reciprocal countermeasures. China's "unexpected winner" position comes from the U.S. internal system's self-correction, not from diplomatic offense.
9. Market Wait-and-See Suppresses Reshoring
The enormous uncertainty of the next three years will suppress the return of capital and industry to the United States. This forms an irony for Trump's core goal of "manufacturing reshoring" — the more he pushes tariffs, the less willing companies are to invest in America, because they have no idea what the policy will look like 180 days from now.
10. The Global Supply-Chain Reconfiguration Is Irreversible
The Supreme Court's ruling is only an interlude; the grand historical trend will not change — global supply chains are reconfiguring along geopolitical fault lines. Trump's obsession with each individual tariff may not be what endures, but the disruption he has wrought on the global trading system has already become one of his largest political legacies.
II. Key Timeline
| Date | Event |
|---|---|
| 2026-02-20 | Supreme Court rules 6–3 that IEEPA tariffs are unlawful |
| 2026-02-24 | IEEPA tariffs formally expire; Section 122 10% tariff takes effect |
| 2026-02-26 | Section 122 raised to 15% |
| 2026-07-24 | Section 122 expires (probability of congressional extension ≈ 0) |
| 2026-07~ | Section 301 investigations completed one after another; new country-specific tariffs take effect |
| Ongoing | Section 232 industry investigations advance in the same window |
| 2026-11 | Midterm elections (Republicans avoid the tariff topic) |
| 2027–2028 | New tariffs face the Nth round of judicial challenges |
The Trump administration claims it wants to build a "stable, sustainable" tariff system, but all the substitutes face higher judicial risk — the more stable the system, the easier it is to overturn. The core logic of Section 301 (trade deficit = unfair trade) does not hold up on its own merits. A tariff system whose stated goal is to "reduce uncertainty" is generating more of it.
III. A Structural Judgment
The fundamental contradiction of the Trump tariff regime is this: its power rests on unilateralism and personal authority, while the U.S. system of government (separation of powers, the rule of law, judicial review) is specifically designed to constrain unilateralism. Once the Supreme Court took back the IEEPA "big stick," Trump lost his most flexible tool; every weapon that remains comes with its own "instruction manual" and "expiration date." This is not a policy adjustment — it is an institutional reclamation of power.
From a broader perspective, this tariff contest exposes a deeper structural fact:
- Institutional constraint is still operative — even though Trump has repeatedly challenged the courts and Congress, the U.S. separation of powers still functioned as a check at the critical moment
- The boundary of executive power — the power of taxation clearly belongs to Congress; the President's use of "emergency states" to bypass Congress and levy taxes has been fundamentally questioned
- The new shape of the coming contest — from a "tweet-then-tariff" intimidation mode, to a slow, procedural, fragmented legal contest; the tempo and nature of tariff warfare will both change
