Tariffs, Time, and the Constitution

Trump’s latest tariff gambits manage to defy economic logic, statutory limits, and constitutional structure all at once, and that makes them unusually useful as case studies in how not to govern trade. His maneuvers under IEEPA to suspend the de minimis exemption, and under Section 122 of the Trade Act to float a blanket 10 percent tariff on the world, are not just bad policies; they are abuses of delegated power that strip away the very constraints a liberal trading order depends on. They weaponize emergency statutes and obscure balance‑of‑payments language to deliver short‑run political optics while shoving the real costs—economic, legal, and institutional—onto a temporally distant and politically voiceless set of future losers.  

Trump’s De Minimus Crackdown

For years, Americans could order low‑value items from abroad—books, widgets, collectibles—under a clear, rules‑based system that allowed such packages to enter duty‑free up to $800. In August 2025, Trump invoked the International Emergency Economic Powers Act (IEEPA) to effectively suspend that de minimis exemption, imposing tariffs on mail‑order imports from platforms like eBay and Etsy. Suddenly, a $40 part from Germany or a $60 accessory from Japan arrived with an extra bill attached, all in the name of “getting tough” on foreign sellers. 

The legal problem here is not subtle. IEEPA is an emergency sanctions statute; it was drafted to deal with foreign threats and crises, not to give presidents an open‑ended power to rewrite the tariff schedule. Recent judicial decisions have made increasingly explicit what should have been obvious: IEEPA does not authorize tariffs, and using it as a vehicle for broad‑based import duties collides with the Constitution’s requirement that new taxes originate in Congress. Federal courts applying that decision have invalidated Trump’s IEEPA‑based tariffs, even if some of the duties remain in place temporarily under stays while litigation continues. 

Once you accept that IEEPA cannot be used to impose tariffs, the August de minimis crackdown collapses. If the statute cannot support tariffs, then the duties collected on low‑value imports under that supposed authority were never lawful taxes in the first place. That reality creates a natural target for litigation: a class‑action suit on behalf of everyone who ordered a sub‑$800 item from abroad and was assessed duties because of the IEEPA‑based suspension of de minimis treatment. The harm here is monetary, the class is clearly defined, and the remedy—refunds of unlawfully collected tariffs—flows directly from the courts’ own understanding of the statute. 

The beneficiaries of this maneuver are easy to identify: domestic producers and sellers who enjoy a bit of insulation from foreign competition when every imported trinket suddenly costs more. The losers are scattered and unorganized—households and small buyers who each pay an extra $10 or $20 at a time. That asymmetry is precisely why statutes like IEEPA must be interpreted narrowly. Left unchecked, they become vehicles for quiet, one‑sided transfers from the many to the few. 

Section 122 and a Disappearing Deficit

If IEEPA is being turned into a pseudo‑tariff statute, Section 122 of the Trade Act of 1974—rarely invoked and never applied on a global scale—is being treated as a general‑purpose tax lever that can be pulled at will. Section 122 allows the president to impose up to a 15 percent surcharge or equivalent restrictions on imports if—and only if—the United States faces a “large and serious” balance‑of‑payments deficit. Trump has floated the idea of using this authority to impose a flat 10 percent tariff on imports from the entire world, presenting it as a necessary response to America’s external imbalances. 

But the statute does not say, “whenever the president dislikes the trade numbers.” It ties the authority to a specific economic condition: a genuine, serious deficit in the balance of payments, in the technical sense used by international accounts. The current data simply do not cooperate. The Bureau of Economic Analysis reports that the U.S. current account deficit for the third quarter of 2025 was $226.4 billion, or 2.9 percent of GDP, down from earlier periods. For 2025 as a whole, the deficit on trade in goods and services narrowed to about $901.5 billion, while capital inflows continued to finance U.S. investment without any indication of an imminent balance‑of‑payments crisis. 

In other words, there is no “large and serious” balance‑of‑payments deficit in the sense Section 122 was written to address. The United States continues to run a trade deficit in goods and services, but that has been a feature of the American economy for decades, and it is offset by robust capital inflows as foreigners invest in dollar‑denominated assets. Treating this as a statutory trigger for blanket tariffs cheapens the language and severs the supposed link between objective economic conditions and extraordinary trade measures. 

That disconnect is why Trump’s proposed use of Section 122 is ripe for an injunction. The legal claim is simple: a statute conditioned on a “large and serious” balance‑of‑payments deficit cannot be invoked when no such deficit exists, and courts are not obliged to accept a presidential proclamation that contradicts the government’s own data. An injunction would not require the courts to opine on the wisdom of tariffs as such; it would require them to insist that when Congress ties a power to a specific condition, that condition has to be real.

Trade Policy Without Guardrails

Both of these episodes—the de minimis crackdown under IEEPA and the world tariff floated under Section 122—illustrate a broader pattern: trade policy being driven through channels that were never meant to bear that load. Instead of debating tariffs in Congress, subject to open votes and explicit tax legislation, the executive branch has learned to rummage through the U.S. Code in search of vaguely worded emergencies and conditional powers that can be reinterpreted as blank checks. 

This is not an abstract worry. We have already seen what happens when these guardrails are ignored. During Trump’s first term, tariffs justified under “national security” provisions and aggressive IEEPA interpretations raised costs for U.S. firms and consumers, provoked retaliation from trading partners, and failed to deliver the promised closing of trade deficits. Empirical assessments of those earlier rounds consistently found that the costs fell disproportionately on domestic buyers and downstream industries rather than on foreign producers. 

The new wave of measures, if left unchallenged, would deepen that pattern. Using IEEPA to turn everyday mail‑order purchases into tariff events blurs the line between genuine emergency powers and routine revenue raising. Using Section 122 without a qualifying balance‑of‑payments deficit blurs the line between contingent, crisis‑driven authority and a general mandate to tax imports whenever the president finds it politically expedient. Over time, those blurred lines become the new normal, and the exceptional becomes the default. 

This is precisely what a constitutional order built on separated powers is supposed to prevent. Taxation and trade policy are not meant to be the byproduct of creative statutory improvisation by the executive branch. They are supposed to emerge from transparent, legislated choices by Congress, subject to electoral accountability and judicial review when lines are crossed.

Time Horizons and Responsibility

There is another dimension to all of this that is easy to miss if we focus only on statutes and court decisions: the way costs and responsibility are distributed over time. Tariffs are politically attractive in the short run because their supposed benefits—standing up to foreigners, “protecting” domestic jobs—can be trumpeted immediately. The costs, by contrast, accumulate slowly and are often hard to trace back to a specific presidential action: a slightly higher price here, a lost export order there, a relocation decision that never quite pays off. 

That temporal mismatch creates an opportunity for mischief. A president can harvest the headlines today and leave the bill for consumers, businesses, and future administrations to pay down the line. When emergency statutes and conditional powers are abused, that misalignment gets worse. Instead of deliberate, legislated trade policy that is debated and defended in public, we get overnight proclamations that quietly reshape the incentives facing millions of buyers and sellers. 

Temporally distributed accountability is one way of thinking about how to correct that. Our institutions already have built‑in time lags: courts that take months or years to render judgment, legislatures that revisit statutes long after the crises that justified them and reputational consequences that follow officeholders into private life. The question is whether we use those lags to restore balance or to entrench abuses.

In the context of Trump’s tariff agenda, the path is clear. Litigation is not just about stopping a particular policy; it is about forcing delayed consequences back into the time horizon of the people who set those policies in motion. A president who knows that abusing IEEPA to squeeze a few more dollars out of small packages will lead to class‑action refunds and judicial rebukes is less likely to try it. A president who understands that proclaiming a fictitious “large and serious” balance‑of‑payments deficit will be met with an injunction and a detailed judicial opinion narrowing the statute is less likely to treat Section 122 as a toy. 

The Case for Two Key Lawsuits

In a recent public discussion, economic historian Phillip W. Magness outlined two legal challenges that now appear especially salient in light of the courts’ emerging skepticism toward emergency-based tariff authority.

First, a class‑action challenge to the IEEPA‑based suspension of the de minimis exemption on mail‑order items from abroad. The legal hook is the Supreme Court’s holding that IEEPA does not authorize tariffs, extended to the specific context of low‑value imports that were nonetheless subjected to duties. The plaintiffs are ordinary consumers and small businesses who can document that they paid these charges after the August 2025 order. The remedy is straightforward: refunds of the amounts collected, plus a declaratory judgment that IEEPA cannot be used this way. 

Second, a lawsuit seeking an injunction against any attempt to implement a blanket 10 percent tariff under Section 122 in the absence of the statutorily required balance‑of‑payments conditions. Here, the key evidence is BEA’s own data showing that the United States does not currently face a “large and serious” balance‑of‑payments deficit, in any meaningful technical or historical sense. The plaintiffs could include importers facing the tariff, trade associations, and possibly state governments affected by higher import costs. 

These cases are not about courts micromanaging foreign economic policy. They are about insisting that when Congress writes conditions into law, those conditions cannot be waved away by executive fiat. They are about restoring some semblance of order to a system that has drifted toward government by press release and creative legal theory.

And they are about time. Without legal pushback, the pattern is clear: presidents will continue to use whatever statutory scrap they can find to impose tariffs today and leave the cleanup for tomorrow. With it, we have at least a chance of re‑anchoring trade policy in rules that endure beyond one administration, and in a constitutional understanding that remembers who is actually supposed to have the power to tax.
