Episode: Trump Rebuilds His Tariff Wall, Brick by Brick

Date: July 27, 2026
Host: David Gura
Guest: Brendan Murray (Bloomberg Global Trade Editor)
Main Theme:
Exploring the Trump administration's latest wave of tariffs—how they were rebuilt following a Supreme Court setback, the justifications offered, the impact on global trade, and the mounting legal and economic debates surrounding them.

---

Overview

The episode examines President Trump's reimplementation of tariffs after the U.S. Supreme Court overturned his previous measures enacted under the International Emergency Economic Powers Act (IEEPA). The administration is now leveraging Section 301 of the Trade Act of 1974, focusing on forced labor and unfair trade practices. Host David Gura and guest Brendan Murray analyze the economic, diplomatic, and legal implications of these moves, the administration's evolving tactics, and what it all means for markets and global trade relationships.

Key Discussion Points & Insights

1. Background: Why the Tariffs Changed (02:18–03:30)

• Inflection Point with Iran and Rising Inflation:
  The ongoing conflict with Iran includes attacks on oil facilities, driving up crude prices and stoking inflation ahead of the Federal Reserve's key meeting.
• Trump’s Legal Setback and Policy Response:
  The Supreme Court struck down tariffs justified on national security grounds, pushing the administration to seek new legal footing.
• Short-term Tariff Expiry:
  A temporary 10% global tariff expired, after which the administration finalized a more “permanent” tariff, now invoked under Section 301.

2. Tariff Mechanisms: Section 301 Explained (03:17–03:54)

• Section 301 Empowerment:
  "Section 301 allows the US Trade Representative, after an investigation into certain unfair trade practices, to impose tariffs based on a number of different reasons." —Brendan Murray (03:17)
• Broad Application:
  The provision is being wielded arguably more broadly than ever, covering countries such as Switzerland and Canada for alleged forced labor issues.

3. Justifications and Reactions (03:54–06:49)

• Human Rights or Pretext?
  U.S. officials say these are about forced labor and human rights, but skeptics (domestically and abroad) allege it’s just another way to raise revenue.
• Jamison Greer’s Statement:
  "The United States has had a forced labor import ban for nearly a century and rigorously enforces it. It's well past time... for our trading partners to do the same." —Read by David Gura (04:37)
• Country Criticisms:
  Even countries like Switzerland are targeted, sparking outrage since their link to forced labor is unclear.
• Notable Domestic Hypocrisy:
  "There are Americans in prison who are producing goods that are bought in the marketplace. And doesn't that qualify as forced labor...?" —Brendan Murray (05:37)

4. Structure and Scope of the New Tariffs (07:43–08:33)

• How Rates Are Set:
  Countries are split into “buckets” based on prior trade deals and cooperation; those with more “to prove” face 12.5%, those who negotiated caps face 10%.
  • Example: India negotiated itself into the 10% group.
• Exemptions and Carve-outs:
  Energy, food, vehicles, steel, aluminum, and goods under the US-Mexico-Canada Agreement are exempt to soften the blow on consumers and industry.
• Scale:
  "This hits about a trillion dollars worth of US Imports. That's roughly a third of all US Imports." —Brendan Murray (08:33)

5. Market and Policy Impact (09:34–10:24)

• Market Reaction:
  The markets "shrugged it off," viewing this as an incremental change. The average U.S. tariff rose minutely from 10.6% to 10.7%.
• Strategic Intent:
  "This is really just the first, a first step rather than the end of the game. This is the administration trying to piece back together some protectionism..." —Brendan Murray (09:55)

---

Legal and Strategic Perspectives

6. A More Deliberate and Measured Approach (13:20–14:08)

• Legal Precautions:
  Multiple investigations, public hearings, and legal processes are now used to insulate the tariffs from judicial invalidation.
  • "And so what we're seeing now is a more flexible and durable impression court method." —Brendan Murray (14:08)
• No Going Back:
  "These tariffs, for the most part, economists would say, aren't going anywhere." —Brendan Murray (14:57)

7. Mounting Legal Challenges and Precedents (15:13–17:08)

• Lawsuits Begin Immediately:
  "It was only a couple hours after these tariffs took effect that two small businesses filed a lawsuit in the U.S. court of International Trade..." —Brendan Murray (15:20)
• Section 338 and Surprise Moves:
  Trump threatened 50% tariffs on Canada using a rarely-used legal authority, sending shockwaves through the trade legal community.
• Uncertainty and Precedent:
  "Will that example of Canada become the new normal... when whether he wants to go after the European Union, China, or any other big trading partner where the US runs a big deficit?" —Brendan Murray (16:44)

8. China and the “Excess Capacity” Case (17:08–18:48)

• Next Front: Chinese Overproduction:
  The administration is investigating countries (especially China) for “excess capacity”—industrial overproduction that “floods the market.”
  • Ongoing, resource-intensive, and expected to intersect with the upcoming Trump-Xi summit.

---

The Future: Is the Wall Complete? (18:48–21:08)

• Still Building:
  "I sort of feel like we're at the beginning of the new wall and that this 301 on forced labor was kind of the foundation..." —Brendan Murray (19:13)
• Permanent Change Forecasted:
  The approach is piecemeal, legally hedged, and expected to shift the U.S. trade landscape well beyond this administration.
• Political Implications:
  Expect more tariffs, ongoing uncertainty, and consumer price impacts—just as midterms approach.
  • "Democrats really hammered Jameson Greer on the Hill...How can you do this to my constituents? And the administration had better have its talking points pretty sharpened for those kinds of attacks..." (20:41)

Notable Quotes & Memorable Moments

• On Forced Labor Tariff Logic:
  "How can you justify these tariffs on so many countries, paint them all with the same brush, and impose a tariff of 10 to 12.5% on them?" —Brendan Murray (05:54)
• On Political Fallout:
  "...How's that going to sit with the American consumer that are paying higher prices at the pump, at the grocery store, pretty much everywhere you look?" —Brendan Murray (20:28)
• On Tariff Permanence:
  "There's no going back from these. These are not going to come off if a Democrat wins the White House next or a pro free-trade Republican wins..." —Brendan Murray (14:35)

Conclusion

The Trump administration’s reconstruction of a U.S. tariff wall post-Supreme Court defeat reveals a sophisticated, legally cautious approach rooted in Section 301 and other provisions, but fraught with diplomatic pushback, legal vulnerability, and political risk. The measures are likely to become a fixture of U.S. trade policy, with wide-ranging consequences for global commerce and American consumers as more complex and targeted investigations loom.

[David Gura]

the war with Iran is at an inflection point. That's according to Bloomberg Economics. President Trump is considering his next steps and over the weekend there was a pause in strikes by both the US And Iran. But Houthi militants aligned with Iran have fired missiles and drones at Saudi oil facilities, impacting crude prices. That has added to concern about inflation ahead of this week's meeting of the Federal Open Market Committee in the Middle of all this, President Trump decided to impose a raft of new tariffs after the U.S. supreme Court overturned the tariffs the President had put in place on national security grounds, using the International Emergency Economic Powers Act. Countries all over the world waited to see how Trump would try to rebuild his tariff wall. First, there was a temporary measure, a short term 10% global tariff that expired last week. While that was in place, the Trump administration put the finishing touches on another policy in it hopes will be more permanent.

[Brendan Murray]

So Section 301 allows the US Trade Representative, after an investigation into certain unfair trade practices, to impose tariffs based on a number of different reasons.

[David Gura]

That's Brendan Murray, who's Bloomberg's Global trade editor. Section 301 is part of the Trade act of 1974.

[Brendan Murray]

Essentially, if American companies, American workers are being disadvantaged in any way from competition overseas, this allows the government, government to legally justify tariffs against certain countries imports. And that's what we've seen here.

[David Gura]

Countries from Australia to Switzerland have expressed their disappointment and they've denied what the US has alleged that they haven't done enough to keep forced labor out of their supply chains. These new tariffs went into effect on Friday at midnight New York time. And now companies and countries are trying to make sense of them and lawyers are considering court challenges that will determine whether the policy sticks. I'm David Gura and this is the big take from Bloomberg News. Today. On the show, Bloomberg's Brendan Murray breaks down the latest levies imposed by the Trump administration, how they came about, who they impact and what they reveal about the administration's approach to trade. In announcing these tariffs, Jamison Greer, the US Trade Representative, said in a statement, the United States has had a forced labor import ban for nearly a century and rigorously enforces it. It's well past time, he said, for our trading partners to do the same. Brennan, what do we know about the rigor of these investigations if the administration's claims against these countries are in fact founded?

[Brendan Murray]

So what we're gonna see over the coming weeks is a lot of legal debate about whether these are justified or not. American importers are gonn why am I paying a duty based on forced labor from the products that I'm importing from Switzerland? Probably as far from forced labor as you might think a country could be. That's because the administration has judged that countries, including Switzerland and Canada and many in Asia have not enforced their forced labor rules and regulations adequately enough or they don't have the rules on the books at all. So what we're seeing is the administration say, look we're just trying to level the playing field for American workers. Now, there are arguments that this won't hold up in court as well. Some people point to the fact that. And the apparel industry would raise these issues too. There are Americans in prison who are producing goods that are bought in the marketplace. And doesn't that qualify as forced labor for people who work and get paid 50 cents an hour or nothing at all? So there's going to be a lot of finger pointing, but ultimately the question is going to come down to how can you justify these tariffs on so many countries, paint them all with the same brush, and impose a tariff of 10 to 12.5% on them?

[David Gura]

How strongly are they making the case here that this is about human rights? I drew the connection between those IPA tariffs being struck down and they having to kind of scramble to find some other means by which they could put these tariffs in place. Are they pushing back against the notion that they were looking for another means of doing this? Are they saying this really is about human rights? How are they making that claim in this release?

[Brendan Murray]

Yeah, that's one of the main criticisms that the administration has already heard, that this is just a pretext to collect money and to pad the treasury revenue. You know, it's kind of hard to argue against crackdowns on forced labor. No one wants to see that. But whether you can justify tariffs based in such a broad way is a whole nother issue that the lawyers are going to try to figure out. And, you know, the President and his advisors now say that they are trying to follow the letter of the law to take these procedures. There were public hearings on these forced labor tariffs. Governments came to the table and said, hey, look at what we're doing. And so there's a lot of documentation about whether the countries are abiding by their forced labor rules and not. And so we're going to see a lot of that sort of aired as countries try to push back against this.

[David Gura]

How does it break down by country? How do you differentiate sort of who gets a higher tariff than another?

[Brendan Murray]

It depends on a couple things. Number one, do you already have a trade deal with the administration? And the U.S. trade Representative, Jameson Greers, told Congress the other day that he has 19 of these. And so if you negotiated the other country negotiated a 10% cap, then that's basically you're in the 10% bucket. Countries with more to prove, with less evidence to defend against the U.S. s accusations wound up with 12.5%. So some countries, India was among them, moved from a proposed 12.5% to the 10% basket between the time of the proposal in early June and the announcement that we just got.

[David Gura]

How about exemptions? Do we see a lot of exemptions in this decision so far? Are there likely to be more of them?

[Brendan Murray]

Yeah, I mean, Bloomberg Economics has calculated that this hits about a trillion dollars worth of US Imports. And so that's roughly a third of all US Imports. And so there are a lot of carve out energy, food, things that are subject to other tariff authorities like cars and steel and aluminum, USMCA, the U.S. mexico, Canada Trade Agreement. Goods that flow under those terms aren't subject to this. So there are a lot of holes in this tariff wall that the President is reconstructing after his Supreme Court loss. And a lot of those are meant to address the concerns that consumers have and that companies have. But that still doesn't completely explain away that the president from day one of his first administration and his second administration loves tariffs, thinks tariffs are the best economic tool at his disposal, and that hasn't diminished in the least.

[David Gura]

Bren, the tariffs went into effect just after midnight on Friday New York time. How has the market reacted to the imposition of these tariffs?

[Brendan Murray]

The market is kind of shrugging this off so far. We'll have to wait and see how it plays out. But the market seems to be absorbing this as this is just a continuation of a roughly 10% tariff. The Bloomberg Economics estimate of the average U.S. tariff rate now went from 10.6% to 10.7%. So not really much more than a blip in the overall kind of economic impact. But it's something that we see as really just the first, a first step rather than the end of the game. This is the administration trying to piece back together some protectionism around the industries that it's trying to revitalize.

[David Gura]

Coming up, we discuss the legal challenges the administration faces and what this latest round of tariff says about the administration's strategy going forward.

[David Gura]

I spoke with Jameson Greer, the U.S. trade representative, in mid July on Bloomberg TV and he walked me through the process that ultimately led to the imposition of Section 301 tariffs on and I think that was seen as kind of a test case for these new tariffs that we've seen on other trading partners.

[IBM Representative]

So our section 301 investigations, they are legal investigations. We have two sets of hearings, we do two sets of public comments and we're focused on unfair trading practices by Brazil. So we have to have a legal basis to do this.

[David Gura]

It does seem somewhat representative, Brendan, of a more kind of measured and deliberate approach to tariff policy this time around. And I'm curious sort of what we know about what went into this broadly, how the administration decided which countries to target, what justifications to use and more broadly than that sort of what kind of tariffs are gonna have the highest likelihood of standing up in court?

[Brendan Murray]

The administration would say that their number one priority is to reduce the trade imbalances that exist around the world. And in places where American farmers and American manufacturers face an unlevel playing field, they're trying to fix that situation and they're trying to open up markets in other places for US Exporters to sell what they make. And so these latest authorities that they're using are really designed to piece by piece, reestablish what the President tried to do last year with his so called reciprocal tariffs, where he just kind of imposed them at will. And so what we're seeing now is a more flexible and durable impression court method. And a lot of people say, look, there's no going back from these. These are, these are not going to come off if a Democrat wins the White House next or a pro free trade Republican wins the White House next in the next election. So these tariffs, for the most part, economists would say, aren't going anywhere.

[David Gura]

Are we likely to see legal challenges to these Section 301 tariffs? Any indication of that from the reception they've gotten so far?

[Brendan Murray]

Well, it was only a couple hours after these tariffs took effect that two small businesses filed a lawsuit in the U.S. court of International Trade accusing the Trump administration of misusing its tariff authority. Again, basically saying that this was too broad a use, that the 301 statute is something that should be used in a more targeted way at countries specifically, rather than targeting a whole group of countries like the White House has done with its latest action. And, you know, and I would imagine that the administration is prepared for that. And they, you know, but they feel like that they've covered all their bases. Don't forget there was another trade headline with the President going after Canada with a never before used authority.338 this one kind of came out of nowhere and a lot of people had sort of taken it off our list of potential tools that he could use. He threatened to put 50% tariffs on Canada in 30 days. And Canada's got to figure out how do they come to the table now and negotiate their way out of that situation. And so it adds to the uncertainty. Most of the attorneys who've reacted to those 338 tariffs threats against Canada have said that's going to be interesting to watch in the courts as well, because number one, it's never been used before, and number two, it's being used in a way against a single country that will certainly hit American Importers, their big question is will that example of Canada become the new normal for the president when whether he wants to go after the European Union or China or any other big trading partner where the US Runs a big deficit.

[David Gura]

We've been talking about these investigations into forced labor. There's another series of Investigations under Section 301 centering on excess capacity. What's the government looking into here?

[Brendan Murray]

So this is essentially a government policy that allows factories to produce too much and ship it around the world and kind of flood the market.

[David Gura]

China, notoriously has done this for many years.

[Brendan Murray]

Exactly. So the real focus of the excess capacity case that you're referring to is China. And so that investigation is ongoing. Jamison Greer, the US Trade Representative, has said it's going to take longer. We don't know if longer means a couple more weeks or a couple more months. But it's a lot more complicated than looking into a forced labor case. You're talking about trying to understand the supply chains of lots of industries and how they intersect with other economies. And there's a real factor there that will be difficult for the US to put its finger on. And there are capacity problems in the US Trade Representative's office. They're just, you know, that takes a lot of people. As Jamison Greer said the other day. He said, I've got dozens and dozens of attorneys working on this particular case. And in their perspective, it has to be built on a solid basis. And so sounds like it's going to take longer. If it takes a couple of months, then you're kind of bumping up against the Trump Xi summit meeting that's supposed to take place in September. And so do you really want to be imposing more tariffs on China ahead of this big meeting that President Trump wants to have with the Chinese leader?

[David Gura]

Brendan, let me ask you lastly, just for your perspective on how high this tariff wall is, how far along job is. So we've got these 301 tariffs. Sounds like more on the way you mentioned the section 338 tariffs on Canada. Meanwhile, negotiations continue with all of these other nations separate from this. Where are we in this process? How close are we to that wall being finished?

[Brendan Murray]

I sort of feel like we're at the beginning of the new wall and that this 301 on forced labor was kind of the foundation that the US Trade Representative's office has laid. Don't forget we' to have. You know, there are all sorts of tariffs threatened on pharmaceuticals, all sorts of other kinds of imports that the US Administration wants to protect. President Trump threatened to put tariffs on the European Union for the fines that it's imposing on Google. Almost a billion dollar fine. President Trump said he was going to order an immediate investigation under 301 into this practice by the European Union. And so this is really the beginning of the new wall. And what we can expect is it's going to be bumpy, it's going to be difficult to predict, and it will bring its own kind of uncertainty, different from the kind that we experienced when President Trump wielded his tariff authority that the Supreme Court struck down. This new process promises to be complicated, maybe slow, and it will have holes in it as well as inflation kind of rears its head again with the Iran war dragging on. The administration, by its own account, wants to keep rolling out tariffs right into the teeth of the midterm elections. And you know, how's that going to sit with the American consumer that are paying higher prices at the pump at the grocery store pretty much everywhere you look. And Democrats really hammered Jameson Greer on the Hill on those issues. Is, you know, how could you, how can you do this to my constituents? And the administration had better have its talking points pretty sharpened for those kinds of attacks on the political front.
