DECODING: Section 122 and Trump tariffs — when the Supreme Court forces protectionism to reinvent itself

Introduction: February 20, 2026 — the Court breaks Trump's toy

The Learning Resources v. Trump ruling — a historic 6-3

On February 20, 2026, the United States Supreme Court issued a decision that would force the Trump administration to rewrite its entire trade arsenal. In Learning Resources v. Trump, the Court ruled 6 to 3 — with Chief Justice John Roberts writing the majority opinion — that the IEEPA (International Emergency Economic Powers Act) did not authorize the president to impose sweeping general tariffs. Roberts used a pointed formulation: "extravagant by any measure" — to describe the presidential interpretation of the IEEPA.

This decision dismantled the primary legal lever the Trump administration had been using to impose universal 10% tariffs and higher targeted tariffs on specific trading partners. Within hours, the most ambitious — and most contested — tariff strategy since the 1930s was left without a legal foundation. The White House response was immediate and revealing: Trump signed the same day a rarely-used statute that would become the new pivot of his trade strategy.

Section 122: an old statute brought back to life

Section 122 of the Trade Act of 1974 is a legislative instrument that had been gathering dust in the congressional archives for half a century. It authorizes the president to impose a maximum 15% surcharge on imports for a period of no more than 150 days under circumstances of serious balance-of-payments imbalance. Trump invoked it on February 20, 2026 to impose an initial 10% surcharge on all American imports — replacing, in emergency fashion, the IEEPA tariffs invalidated by the Supreme Court.

The problem was immediately apparent: the 150-day limit written into the statute meant that Section 122 would expire around July 20, 2026. The administration had therefore bought only a few months to rebuild its tariff architecture on more solid legal foundations. This deadline immediately raised the question of what would happen after — and what other legal tools the administration could use to sustain its protectionist policy.

The International Trade Court invalidates Section 122 tariffs

The CIT ruling of May 7, 2026 — a second legal blow

On May 7, 2026, the Court of International Trade (CIT) delivered a second blow to Trump's tariffs by declaring the Section 122 tariffs invalid as contrary to law. The CIT determined that the conditions for invoking Section 122 — a serious and imminent balance-of-payments imbalance — were not met in the case of Trump's universal tariffs, which aimed to alter trade behavior rather than respond to a balance-of-payments emergency in the strict sense of the statute.

But there was a crucial caveat: the CIT ruling was accompanied by a stay of execution pending appeal. This stay means the tariffs continue to be collected while the case moves up the judicial chain. American importers paying these tariffs therefore began accumulating refund claims — through a system called CAPE (Customs and Automated Payments for Exports) — in hopes of being reimbursed if courts ultimately confirm the tariffs' invalidity. Phase 2 of the CAPE portal was scheduled to open on June 29, 2026.

The logic of the stay — why the tariffs continue

The logic of a stay pending appeal is a pragmatic decision by the American judicial system: immediately stopping the collection of billions of dollars in tariffs based on a single first-instance ruling would create immediate economic and commercial chaos. But maintaining the tariffs while awaiting the final appeal outcome means that billions of dollars are being collected on the basis of a policy that courts have found illegal — a paradox that trade lawyers describe as a practical denial of rights for importers.

Appeal proceedings at the Federal Circuit level and potentially the Supreme Court could take one to two years. In the meantime, tariffs apply, goods become more expensive, supply chains adapt — and businesses are betting on the final outcome. This is a massive legal uncertainty that is itself an economic cost, independent of whatever tariff rate is applied.

Section 301 as a potential successor — what Bessent said

The Treasury Secretary and the transition to Section 301

Facing the imminent expiration of Section 122 tariffs and ongoing judicial uncertainties, Treasury Secretary Scott Bessent signaled that the administration was preparing to use Section 301 of the Trade Act of 1974 as a replacement mechanism. Section 301 authorizes the United States Trade Representative (USTR) to impose tariffs on countries adopting unfair trade practices — and its interpretation is potentially broader and legally more defensible than IEEPA or Section 122.

The USTR had launched Section 301 investigations against 60 economies in the weeks following the Supreme Court ruling. These investigations are a procedural prerequisite for imposing Section 301 tariffs — they justify presidential action through a documented administrative process, reducing the risk of judicial invalidation. Bessent had stated that Section 301 would allow the administration to restore tariff levels once investigations were completed.

Section 301 vs. IEEPA vs. Section 122 — the key differences

Understanding the differences between these three instruments is essential to decoding Trump's tariff strategy. The IEEPA allowed unilateral and immediate imposition based on a national emergency declaration — fast but constitutionally fragile, as the Supreme Court confirmed. Section 122 allowed temporary imposition limited to 150 days and a maximum 15% — a short-range solution. Section 301 requires preliminary investigations but offers a more robust legal basis, potentially permanent tariffs, and potentially unlimited rates — at the cost of a procedural delay of several months.

The Trump administration therefore used a sequence: IEEPA to impose quickly, Section 122 as an emergency backup, Section 301 as the permanent solution under construction. It is a tariff architecture built under legal pressure — pragmatic, but revealing the constitutional limits of a protectionist strategy that had not fully anticipated judicial resistance of this magnitude.

The impact on trading partners — Canada, Europe, China

Canada and the progressive exception

Canada, the United States' primary trading partner, has been particularly affected by Trump's tariffs. Tariffs on Canadian steel and aluminum, automotive tariffs, and general tariffs have created significant bilateral tensions in a commercial relationship long presented as a model of North American economic integration. The Carney government — elected in part on its management of the Washington relationship — had to negotiate partial exemptions while maintaining retaliatory measures on politically targeted American goods.

The CUSMA (Canada-United States-Mexico Agreement) provides dispute resolution mechanisms, but they are slow and their outcomes do not directly bind the American president. Canada has turned toward trade diversification — notably toward Europe through CETA and toward Asia-Pacific — to reduce its dependence on exports to a market subject to unpredictable tariffs. This diversification is a rational response to structural American unpredictability.

Europe and digital services taxes

On June 26, 2026, Trump threatened to impose tariffs of 100% on countries maintaining digital services taxes (DSTs) targeting American companies — notably the tech giants (Google, Amazon, Facebook, Apple). This threat directly targets France, which has imposed a 3% DST on digital revenues, and other European countries considering similar measures. It is a further escalation in the digital trade war between Washington and Brussels.

The European Union responded with a dual strategy: negotiating a comprehensive digital taxation agreement within the OECD framework to avoid bilateral confrontation, while maintaining its position that digital companies must pay taxes where they generate their revenue. This confrontation over DSTs is symptomatic of a deeply strained transatlantic commercial relationship — going well beyond tariffs on industrial goods.

The CAPE portal and tariff refunds — importers in the fog

The CAPE Phase 2 mechanism — how it works

The CAPE (Customs and Automated Payments for Exports) Phase 2 portal, scheduled to open on June 29, 2026, is designed to allow American importers to file refund claims for tariffs paid under tariff regimes that have been declared invalid by the courts. The mechanism is simple in theory: the importer documents its payments, submits them through the portal, and receives — theoretically — a refund once invalidity is definitively confirmed.

In practice, the system is complicated by procedural uncertainty: the courts have not yet rendered their final verdict. Refunds are not certain until the government's appeal is decided. Importers must therefore make a delicate financial calculation: file claims now (administrative cost, capital tied up) to maximize their chances of future reimbursement, or wait for legal certainty (risk of missed deadlines or procedures).

The impact on small and medium-sized importing businesses

Small and medium-sized enterprises (SMEs) importing goods are those most affected by this uncertainty. Large multinationals have legal and financial teams capable of navigating the complexity of the CAPE portal and financing the wait for refunds. SMEs, by contrast, face immediate cash flow problems: paying tariffs on imports compresses their margins, sometimes to the point of nonviability, without any guarantee of short-term reimbursement.

The firm Sheppard Mullin, specializing in international trade law, has documented hundreds of cases of American SMEs in difficulty because of this tariff uncertainty. The aggregate economic cost — in terms of compressed margins, delayed investments, and disrupted supply chains — is difficult to quantify precisely but is unanimously recognized as significant by economists who have analyzed available data.

Section 301 investigations against 60 economies — an unprecedented scope

A mass investigation as tariff preparation

Launching Section 301 investigations against 60 economies simultaneously is an unprecedented act in the history of American international trade. Traditionally, Section 301 investigations targeted specific countries or sectors — China for intellectual property, for example. Targeting 60 economies at once transforms Section 301 from a surgical tool into an instrument of global commercial pressure.

The targeted countries cover virtually all of the United States' major trading partners: the European Union (treated as a single entity), Japan, South Korea, India, Mexico, Canada, Australia, and a range of emerging economies. The investigations concern unfair trade practices — subsidies, currency manipulation, non-tariff barriers, intellectual property violations. The list of grievances is long, documented, and largely legitimate — even if the universal tariff response is debated.

The WTO's reaction and the limits of commercial multilateralism

The World Trade Organization (WTO) has responded to Trump's tariffs with available tools — notably the Dispute Settlement Body (DSB) — but these tools are structurally limited. The DSB can find that a tariff violates WTO rules, but implementing its decisions depends on the goodwill of the states concerned. And the United States under Trump has clearly signaled it will not allow itself to be constrained by multilateral panels.

The WTO crisis runs deeper than Trump's tariffs alone: its appellate mechanism has been paralyzed since the United States blocked new judge appointments in 2019. It is an institutional crisis of commercial multilateralism that Trump has aggravated but did not create alone. Europe and other trading partners must decide whether they want to revive the WTO or build alternative commercial governance mechanisms — a decision that will shape the global economic order for decades to come.

Tariffs on technology — Huawei, chips, and the tech war

The technological dimension of Trump's tariffs

Trump's tariffs do not only target traditional industrial goods — steel, aluminum, automobiles. They are part of a broader strategy of technological decoupling from China. Restrictions on exports of advanced semiconductors to China, Section 301 investigations on Chinese technologies, and tariffs on Chinese solar panels and batteries form a coherent whole aimed at reducing American dependence on Chinese technologies and maintaining American technological superiority.

This technology war has profound consequences for global semiconductor supply chains. TSMC (Taiwan), Samsung (South Korea), and Intel (United States) are the central players in a reconstitution of chip manufacturing chains that Trump's tariffs are accelerating. The American objective — repatriating chip production to the United States via the CHIPS Act — is strategically logical but industrially complex and expensive in the short term.

Tariffs as industrial policy — and their limits

The vision behind Trump's tariffs is not purely protectionist in the classical sense. It is also an industrial policy aimed at incentivizing the relocation of strategic production to the United States or to trusted allies — what is called friend-shoring or near-shoring. This logic is defended by economists who argue that national security considerations justify some short-term economic inefficiency.

But the limits are real: tariffs are a blunt instrument for nuanced industrial policy. They increase input costs for American industries dependent on imports. They trigger retaliation that reduces American exports. And they do not necessarily incentivize companies to invest in the United States if other factors — labor costs, infrastructure, workforce qualifications — remain less favorable than elsewhere. The CHIPS Act and the Inflation Reduction Act are necessary complements to tariffs — but their long-term effectiveness remains to be demonstrated.

What July 20 means — the expiration of Section 122

A countdown that is accelerating

With Section 122 expiring around July 20, 2026, the Trump administration faces a critical deadline. If Section 301 investigations are not sufficiently advanced to justify immediate imposition, and if no other legal mechanism is ready, there will be a period — perhaps brief, perhaps extended — in which Trump's universal tariffs will have no clear operational legal basis. That is a window of vulnerability for the presidential trade strategy.

Sources close to the USTR, cited by CNBC on June 26, 2026, suggest that Section 301 decisions could be made public before July 20 to close this gap. The urgency is real: every day without clear tariffs sends a signal to trading partners that American pressure may be easing — a signal the Trump administration wants to avoid at all costs.

What trading partners can expect after July 2026

For the United States' trading partners — Canada, the European Union, Japan, South Korea — the post-July 20 period is navigable uncertainty. If Section 301 tariffs take over, they will likely be more targeted than the universal tariffs — offering greater sectoral predictability. If tariffs temporarily disappear during the judicial appeal, it is a window of opportunity to renegotiate bilateral agreements.

In any case, the fundamental direction of American trade policy will not change: Trump believes in protectionism, in commercial reciprocity, and in American reindustrialization. The legal tools may vary — IEEPA, Section 122, Section 301 — but the objective remains constant. Trading partners that have invested in diversifying their exports and negotiating alternative agreements are those that will best weather this new American trade reality.

Conclusion: a legally fragile but politically determined tariff landscape

The resilience of American protectionism in the face of the courts

The legal sequence around Trump's tariffs — IEEPA invalidation, Section 122, Section 301 investigations — demonstrates one fundamental thing: the political determination of the Trump administration to maintain high tariffs is structurally stronger than the legal obstacles it encounters. Every time a mechanism is invalidated, another is activated. The American protectionist machine does not stop in the face of a court ruling — it pivots.

This resilience has lasting implications for the international trade system. If the United States — the world's largest economy — can circumvent WTO rules and invalidate its own multilateral commitments through a succession of internal legal instruments, the normative framework of international trade is fundamentally weakened. Europe, Canada, and other trading partners must draw the consequences: commercial multilateralism cannot rely solely on Washington to defend it.

The future of transatlantic trade relations

The transatlantic trade relationship is experiencing a structural crisis that Section 122 or Section 301 alone do not explain. The fundamental divergence between a Europe that believes in multilateral rules and a Trumpist America that believes in bilateral power is a worldview gap in economics. This divergence does not preclude cooperation on other fronts — defense, NATO, Ukraine, China — but it makes every trade round difficult and costly.

The West needs stable trade rules to finance its rearmament, support Ukraine, and maintain pressure on Russia, China, Iran, and North Korea. Trade wars within the Alliance directly undermine this collective capacity. That may be the strongest argument for Washington and Brussels to finally find common ground on trade — not for idealist reasons, but for concrete strategic ones.

Editorial position

The columnist is skeptical about the long-term effectiveness of tariffs as an industrial policy tool, but acknowledges the legitimacy of the objectives of commercial reciprocity and reducing strategic dependence on China. His pro-Western position implies that he prefers commercial cohesion among allies over an intra-Alliance trade war — even if that cohesion is difficult to achieve in the current political context.

China is identified as the central economic and technological threat in the long term. Tariffs aimed at reducing American dependence on Chinese supply chains are seen as strategically rational, even if their side effects on allies are problematic. No financial conflict of interest with the companies, governments, or organizations mentioned in this article.
