The Background in One Sentence

Since the Supreme Court ruled 6-3 on February 20, 2026 that IEEPA does not authorize tariffs — gutting Trump's sweeping Liberation Day tariff structure — the administration has been scrambling to rebuild its tariff wall through every other legal mechanism available.

What Happened Tuesday

On June 3, the Office of the US Trade Representative announced proposed tariffs of at least 10% on imports from approximately 60 trading partners, according to Bloomberg. The stated justification: an investigation into goods allegedly produced by forced labor.

Two tiers. Canada, Mexico, the European Union, Taiwan, and the UK get hit at 10%. China, India, Japan, South Korea, Brazil, and Switzerland get hit at 12.5%.

These are proposed rates, NOT yet in effect. The announcements are already being treated as done deals in mainstream coverage, though formal implementation remains pending.

The Legal Mechanism: This Is NOT IEEPA

This isn't the same legal authority Trump used before.

After the Supreme Court's February ruling, the administration pivoted to Section 122 of the Trade Act of 1974 — a different statute — to impose a 10% temporary surcharge on nearly all imports, effective February 24, 2026, according to the USTR's own website. That Section 122 tariff applies to roughly $1.2 trillion, or 34% of annual imports, and is scheduled to expire after 150 days.

The new forced-labor-based tariffs appear to be a separate track, likely under Section 301, with multiple new Section 301 investigations already underway according to the Tax Foundation's Tariff Tracker, updated May 21, 2026.

Trump is layering multiple legal authorities because no single one survived Supreme Court review. It's strategically complex, legally complicated, and ultimately, consumers are paying for it.

What This Is Actually Costing Americans

The Tax Foundation, tracked by economists Erica York and Alex Durante, puts hard numbers on this.

In 2025, Trump's tariffs cost the average U.S. household $1,000 in additional taxes. The new Section 122 and Section 232 tariffs are estimated to add another $700 per household in 2026.

The weighted average applied tariff rate dropped from 14.9% to 8.2% after the Supreme Court's IEEPA ruling. The Section 122 and Section 232 tariffs brought it back up to 11.7%. If the Section 122 tariff expires on schedule, the full-year 2026 average effective rate lands at 5.7% — still the highest since 1972.

Over the decade from 2026-2035, the Tax Foundation estimates these tariffs will raise $956 billion in revenue on paper. Accounting for economic damage — slower growth, reduced trade — that number falls to $697 billion. Permanent Section 232 tariffs alone will reduce long-run U.S. GDP by 0.3% before foreign retaliation is even factored in.

These tariffs amount to a massive tax increase on American consumers and businesses, regardless of what they're called.

The Forced Labor Framing: Legitimate or Convenient?

The administration is invoking forced labor as the legal and moral justification. Is it accurate? Probably, in many cases. China's Uyghur forced labor practices are real and documented. But applying the same investigation framework to Canada, the EU, and the UK — democratic allies — as a path to reconstructing tariffs that the Supreme Court struck down raises an obvious question: is this genuine labor enforcement, or creative legal cover?

Mike Pompeo, former Secretary of State, weighed in on Bloomberg on June 3 and appeared supportive of the approach. He's been a consistent advocate for aggressive trade posture toward China specifically, and his view carries weight on that issue. His credibility is thinner when justifying 10% tariffs on the UK.

What Mainstream Media Is Getting Wrong

Left-leaning outlets are covering this primarily as economic damage and political chaos — fair on the numbers, but they're underselling the Supreme Court's role as the actual driver here. The IEEPA ruling changed everything, and that context keeps getting soft-pedaled.

Right-leaning outlets are largely cheering the tariffs as tough negotiating without seriously engaging the Tax Foundation math: $700 more per household this year, GDP reduction, and a tariff rate not seen since the 1970s.

Neither side is clearly explaining that multiple legal mechanisms are now in play simultaneously — Section 122, Section 232, and now Section 301 — and that each has different legal durability, different expiration timelines, and different WTO implications.

What Comes Next

The Section 122 tariffs expire in approximately 150 days from February 24 — meaning they sunset around late July 2026 unless renewed or replaced. The forced-labor Section 301 investigations now underway could produce permanent, legally sturdier tariffs on specific products and countries.

Trading partners — particularly the EU — have already demonstrated willingness to retaliate. The EU-U.S. framework agreement from July 2025 is now under significant strain, according to USTR documents showing ongoing implementation disputes.

The Tariff Wall Continues

Trump's tariff ambitions didn't die with the Supreme Court's February ruling — they just got more complicated and more expensive to administer. The administration is now running at least three parallel tariff tracks simultaneously, each with different legal authority, different expiration dates, and different products covered.

Regular Americans are paying the bill. The Tax Foundation says $700 per household this year on top of last year's $1,000.

If these tariffs produce genuine trade deals that lower barriers and bring manufacturing home, the cost might be worth debating. So far, the deals with the UK and Indonesia exist on paper. The EU framework is fragile. Canada and Mexico are being hit again despite USMCA existing for exactly this purpose.

The tariff wall is being rebuilt brick by brick. Somebody should ask what it's actually protecting — and who's paying for the construction.
