The Tariff's Two Tracks

In the last week of January, Donald Trump raised tariffs on South Korean goods from 15% to 25%, citing delays in promised U.S. investment.

Because the Korean Legislature hasn’t enacted our Historic Trade Agreement, which is their prerogative, I am hereby increasing South Korean TARIFFS on Autos, Lumber, Pharma, and all other Reciprocal TARIFFS, from 15% to 25% — Donald Trump

Within weeks, both of South Korea's major parties agreed to expedite a $350 billion U.S. investment bill through the National Assembly ^[1].

The National Assembly's timely passage of the bill is extremely important. — Yeo Han-Koo

The tariff lever had produced exactly the result it was pulled to produce: a threat, a number, a concession. The same weapon, aimed at a different target with a different ask, produced the opposite. In February, Indian and Russian officials met in Moscow to discuss expanding investment ties ^[2]. By June, Trump had escalated tariffs on India to 50%, explicitly over its continued purchase of Russian oil — and rejected his own USTR's trade data to justify the move ^[3].

Those who won't build here are going to have massive tariffs to pay... not 20 percent, like 100 percent. We're treated so unfairly; China tariffs us over 150 to 200 percent, India 175 percent. — Donald Trump

India did not stop buying Russian oil. A CNAS policy paper identified the steep tariffs as a primary driver of strategic mistrust, warning the friction could undermine cooperation in semiconductors, AI, and critical minerals ^[4]. The economic track kept delivering. In February, Trump linked tariff reductions for Japan directly to a $550 billion investment pledge, using the threat of returning tariffs to 25% as the lever ^[5].

The Trump administration is a very tough administration. — Ryosei Akazawa

In June, the administration cut tariffs on agricultural and industrial equipment — but only for machinery with at least 85% U.S.-sourced steel, aluminum, or copper by weight, turning the carve-out itself into an onshoring incentive ^[6].

President Trump has utilized tariffs on imported aluminum, steel, and copper to protect the national security of the United States, the economic resilience of vital industries, and the financial position of American families, communities, and businesses from the threat of low-priced foreign imports. — Donald Trump

The pattern was consistent: tariffs went down when capital came in. The geopolitical track kept deteriorating along multiple fronts. Canada, facing 100% tariff threats tied to Arctic sovereignty and NATO spending demands, diversified trade toward India and China, including a canola-for-electric-vehicle-market-access deal with Beijing ^[7][8]. In Europe, Trump threatened tariffs on nations opposing the Greenland seizure. Denmark and Greenland rallied support in Berlin and Paris. Emmanuel Macron called for European strategic sovereignty and reduced dependence on the United States; Mette Frederiksen urged urgent European rearmament ^[9].

Recent events confirm that the situation in Greenland is a strategic wake-up call for all of Europe: on asserting our European sovereignty, on our contribution to Arctic security, on combating foreign interference and disinformation, on the fight against climate change, and on a privileged partnership for sustainable development and reducing strategic dependencies. — Emmanuel Macron

The best way forward for the United States, Europe is to stick together. — Mette Frederiksen

The fork was visible before the courts got involved. The economic ask — invest here, build here — produced results. The geopolitical ask — stop buying Russian oil, concede sovereignty, align foreign policy — produced the opposite. What the courts did was kill the blunt instrument and force the administration into a narrower legal vehicle. On February 22, the Supreme Court struck down the sweeping IEEPA-based tariff program in a 6-3 ruling ^[10]. Trump immediately imposed replacement tariffs under Section 122 of the Trade Act of 1974, calling them "new and legally permissible" ^[11].

new and legally permissible — Donald Trump

But the Justice Department had previously argued in court that Section 122 had "no obvious application" for fighting trade deficits ^[12].

We are not quite sure how to translate 1974 into 2026, but we do know that the ‘balance of trade deficit’ was not the same thing as the ‘balance of payments deficit’. — Timothy C. Stanceu

On May 7, the Court of International Trade struck down the Section 122 tariffs too ^[13]. The rate had already crept from 10% to 15% in the months between — the replacement regime was not a fixed legal strategy but an escalating improvisation. Trump's response captured the administration's entire approach.

Nothing surprises me, so we always do it a different way. We get one ruling, and we do it a different way. — Donald Trump

The administration needed a legal vehicle that could survive judicial review, and it found one in Section 301 of the Trade Act of 1974. The statute came with a built-in constraint: each tariff had to target a specific unfair trade practice in a specific country. The administration turned that constraint into a feature. It launched Section 301 investigations into forced labor across 60 economies, excess manufacturing capacity across 16 trading partners, and specific domestic policies in individual countries — Germany's pharmaceutical pricing, Brazil's deforestation rules and digital payment platform, Vietnam's intellectual property practices, Europe's digital services taxes ^{[14][15][16][17][18]}.

In many sectors, the United States has lost substantial domestic production capacity or has fallen worryingly behind foreign competitors. — Jamieson Greer

Each probe looks surgically targeted at a discrete grievance. Collectively, they cover more than 99% of U.S. imports ^[14].

the levies are “critical” to keeping trade partners engaged in negotiations. — Jamieson Greer

USTR Jamieson Greer made the connection explicit, describing the Germany pharmaceutical probe as part of "a broader effort to find alternative methods for imposing trade penalties after the Supreme Court struck down several tariffs" ^[15].

I am particularly concerned with news that Germany is fast-tracking legislation that would further reduce its spending on innovative pharmaceuticals. — Jamieson Greer

The legal requirement for specificity had become the diplomatic pressure point. Vietnam faces three concurrent probes — forced labor, excess capacity, and IP practices — each a separate legal predicate building toward the same tariff outcome ^[17].

We need to see Vietnam resolve these long-standing concerns, including on a range of IP enforcement issues, in a manner that is sustained and that deters future IP infringements. — United States Trade Representative

Brazil's probe targets the PIX payment system, ethanol access, and deforestation rules while exempting beef, coffee, rare earths, and crude oil — the administration surgically targeting policy changes it wants while protecting goods the U.S. economy needs ^[16].

I launched the Section 301 investigation to tackle "longstanding and pervasive U.S. concerns with certain of Brazil's trade policies and practices." — Jamieson Greer

The legal ground beneath all of this is still shifting. The Section 122 tariffs, currently stayed by the Federal Circuit, are set to expire on July 24 unless Congress extends them ^[19]. The Section 301 forced-labor tariffs — proposed against 54 nations — are now under formal challenge. In July, India and South Korea contested the USTR's factual findings at hearings, with India arguing the findings lack basis and noting that exempting 1,600 domestically irreplaceable products undermines the policy's own rationale ^[20].

India would like to highlight its concerns with the USTR's report and findings against India. — Government of India

In conclusion, it is submitted that the USTR reconsider the imposition of tariff in light of the identified inconsistencies in the report in the Federal Register notice. We ask any trade problems be addressed within the framework of the India-US bilateral trade negotiation, not through unilateral measures such as this investigation. — Brij Mohan Mishra

The surgical legal predicates that make the new regime court-resistant are themselves coming under attack from the targets they are meant to pressure. The administration built its third tariff regime around specificity because the courts left it no other choice. But the specificity requirement cuts both ways: it gives each probe legal durability, and it gives each target a discrete finding to challenge. The same Section 301 machinery that squeezed $350 billion out of Seoul is the machinery now pushing Ottawa toward Beijing and New Delhi toward Moscow. The tool does not distinguish between an economic ask and a geopolitical one. The targets do, and they answer accordingly.
