The names changed. The legal framework changed. The target list expanded to 60 countries. But the goal is exactly the same: a sweeping, double-digit tariff wall on global imports and the Trump administration is now on its third attempt to make it stick.
On the surface, the U.S. Trade Representative’s latest announcement looks like a human rights initiative. Dig one layer deeper, and it’s a carefully engineered legal pivot designed to do one thing: keep the tariffs alive before the clock runs out in July.
Three Attempts, One Goal, Here’s What’s Actually Happening
To understand why this announcement matters, you need to understand where it fits in the longer story.
Phase 1 — The Emergency Route (Struck Down): The administration’s original strategy was to impose sweeping global tariffs by declaring trade deficits a national emergency under the International Emergency Economic Powers Act (IEEPA). On February 20, 2026, the Supreme Court shut that down in a landmark 6–3 ruling, the Learning Resources decision concluding that the executive branch cannot use a peacetime emergency law to seize unlimited tariff authority from Congress.
Phase 2 — The Stopgap Route (Expiring): To keep a 10% global tariff alive after that defeat, the White House turned to Section 122, a temporary trade law that allowed a flat tariff to remain in place as a bridge measure. The problem: Section 122 is legally capped at 150 days. That clock expires on July 24, 2026.
Phase 3 — The Forced Labor Route (Now): Knowing the stopgap was running out, the administration launched a sweeping Section 301 investigation in March 2026, concluding that 60 trading partners failed to adequately block imports made with forced labor. That investigation is now the legal foundation for a fresh round of double-digit tariffs built on a framework that has historically been far more resistant to court challenges.
Same wall. New bricks.
What the New Tariffs Actually Look Like
The Office of the U.S. Trade Representative (USTR), led by Jamieson Greer, has divided the 60 targeted economies into two tiers:
The 10% tier covers Canada, Mexico, the European Union, the United Kingdom, Taiwan, Indonesia, Argentina, and roughly a dozen others. These economies either have formal bans or partial enforcement mechanisms in place or have made trade pact commitments but are deemed to have failed to enforce them effectively.
The 12.5% tier covers China, Japan, India, South Korea, Australia, Brazil, Vietnam, New Zealand, and dozens more. These economies are accused of failing both to impose a formal forced labor import prohibition and to enforce any meaningful supply chain restrictions.
Certain agricultural staples including beef, tomatoes, and coffee are reportedly slated for exemptions. The USTR is also floating a “textile mechanism” that would allow a reduced tariff rate on apparel from countries that agree to import an equivalent volume of American textiles.
Why “Forced Labor” and Why Now
U.S. Trade Representative Jamieson Greer framed the new tariffs as a matter of fairness, arguing that failures to block forced-labor goods force American workers to compete on an “unlevel playing field.”
Trade experts and foreign governments are largely not buying that framing, at least not as the primary motivation.
The timing is the tell. The Section 122 stopgap expires July 24. The Section 301 investigation was launched in March. The public comment window closes in early July, with hearings beginning July 7. The sequencing is not coincidental, the administration is building a legally durable replacement for a tariff regime that is about to expire, using a framework that Congress explicitly designed for punishing unfair trade practices and that has historically withstood major court challenges.
By framing the tariffs around forced labor rather than a blanket economic policy, the administration also makes it significantly harder for trading partners to simply call it protectionism in court. They have to argue, specifically, that the forced labor justification is invalid, a much narrower and more difficult legal target.
The Legal Battle That’s Coming
If and when these tariffs are finalized after the July hearings, legal challenges will follow almost immediately. But this time, the outcome is far less predictable than the last.
Why the administration might win: Section 301 of the Trade Act of 1974 was written by Congress as an explicit delegation of tariff authority to the executive branch specifically to punish foreign countries for unfair trade practices. Unlike the emergency law struck down in February, the USTR can point to months of formal investigation, a rigorous administrative process, and statutory language that directly authorizes exactly this kind of action. The Supreme Court is also generally reluctant to strike down executive actions based on suspected motive alone. If the administration followed the Section 301 process correctly, the conservative majority may feel legally bound to uphold it.
Why the Court could still overturn it: Legal scholars including analysts at the Peterson Institute for International Economics (PIIE) have flagged a critical vulnerability. Section 301 is written to address the “acts, policies, and practices of a foreign country” singular. The law was designed for targeted, bilateral disputes like a specific intellectual property fight with one country. Applying it simultaneously against 60 nations to restructure global trade looks far less like a targeted dispute and far more like an executive seizure of Congress’s constitutional power to levy taxes. Courts will also weigh the Major Questions Doctrine, the principle that executive agencies need explicit congressional authorization for decisions of vast economic significance. Opponents will argue Congress never intended a bilateral trade dispute clause to be used to reorder the entire global economy overnight.
This is going to be a close, consequential fight not the clear-cut constitutional overreach of the last round.
How America’s Closest Allies Are Responding
Neither Canada nor the European Union is rushing into an immediate tariff war. Both have calculated that the smarter move is to beat the U.S. at its own legal game before July and keep active retaliation ready as a fallback.
Canada has a significant built-in advantage: the USTR explicitly noted that the new 10% tariff will not apply to goods complying with the Canada-United States-Mexico Agreement (CUSMA). Since the vast majority of Canadian exports to the U.S. flow through CUSMA, Canada’s immediate financial exposure is heavily insulated. Prime Minister Mark Carney’s government is moving quickly to introduce strict new supply chain legislation designed to match or exceed U.S. forced labor standards dismantling the USTR’s legal justification before the July hearings even conclude.
The European Union is particularly frustrated by the timing. The U.S. announcement came just two weeks after the EU ratified a transatlantic trade pact with the Trump administration, a deal specifically designed to cap tariffs on most EU exports at 15%. Brussels had also just finalized its own sweeping Forced Labour Regulation, making the U.S. accusation of inadequate enforcement feel, to European officials, like a deliberate breach of trust. EU Trade Commissioner Maroš Šefčovič and colleagues plan to use the U.S. public comment window to demonstrate that European supply chain enforcement is already robust. More significantly, European lawmakers had the foresight to insert “snapback” clauses into the recently signed bilateral deal if the U.S. imposes unjustified new duties, the EU has pre-approved legal authority to instantly reinstate heavy tariffs on high-profile American exports, specifically targeting U.S. automotive parts and motorcycles.
Both Ottawa and Brussels are clear that active, large-scale retaliation remains on the table if Washington refuses to engage. Canada still maintains active reciprocal tariffs on U.S. steel, aluminum, and automobiles from previous trade disputes, which it can scale up quickly. The EU’s snapback clauses require no additional negotiation, they can be triggered unilaterally.
The Public Comment Window and What Comes Next
These tariffs are not going into effect immediately. The USTR has opened a formal review process:
June 22, 2026 is the deadline for companies and representatives to request to testify. July 6, 2026 is the final deadline for written public comments. July 7, 2026 is when official public hearings begin in Washington before the duties can be finalized.
That window is not just procedural. It is the primary battleground where Canada, the EU, and corporate trade groups will make their legal and factual cases and where the administration will need to demonstrate that its forced labor findings are substantive enough to survive the inevitable court challenge that follows.
The July 24 expiration of the Section 122 stopgap looms over all of it. The administration is racing to have Section 301 tariffs finalized or at minimum, formally in process before that date removes its existing legal cover entirely.
Whether this third attempt at a global tariff wall holds up in court will ultimately come down to a question that goes well beyond trade policy: how far can a decades-old bilateral trade dispute law be stretched before it becomes something Congress never authorized?
That answer, when it comes, will be one of the most consequential rulings on executive power in a generation.
