Trump Signed New 10% Global Tariffs Under Section 122 — Four Hours After SCOTUS Said the Old Ones Were Illegal

Trump’s new 10% global tariffs take effect February 24, 2026 — signed under Section 122 of the Trade Act of 1974, just four hours after the Supreme Court struck down his previous tariffs as illegal. The court killed the old ones; he immediately signed new ones. Your grocery bill doesn’t care which statute he used.

Key Takeaways
• Supreme Court struck down Trump’s IEEPA tariffs 6-3 on Feb 20, ruling Congress never granted that authority
• Four hours later, Trump signed new 10% global tariffs under Section 122 of the Trade Act of 1974
• New tariffs take effect February 24, 2026 at 12:01 a.m. — affecting most imports globally
• Section 122 is a never-before-used statute allowing up to 15% tariffs for 150 days max
• After 150 days, Congress must authorize continuation — or the tariffs expire
• Canada/Mexico (USMCA-compliant goods) and some agricultural products are exempted
• Yale Budget Lab estimates the tariffs could cost the average US household $1,900–$2,400 per year in higher prices
• Legal challenges are already being filed — but courts may be more deferential to Section 122 than IEEPA

This morning, millions of Americans briefly exhaled. The Supreme Court — in a 6-3 decision in Learning Resources, Inc. v. Trump — ruled that Trump’s sweeping global tariffs were illegal, that IEEPA never gave a president the authority to impose them. For a few hours, it looked like the legal system had worked. By evening, the cost-of-living squeeze was back on track. The tariffs are different. The prices are going up anyway. And younger workers — already paying for decades of bad economic decisions they didn’t make — will absorb the hit in every grocery run, every Amazon order, and every gas fill-up between now and mid-July.

Feb 23 — 4:00 PM PT: Markets closed sharply lower Monday as tariff anxiety and AI disruption fears combined to sink the Dow. The Dow Jones Industrial Average fell 821 points (−1.66%) to close at 48,804; the S&P 500 dropped 71.76 points (−1.04%) to 6,837.75; the Nasdaq lost 1.1%. Key driver: IBM shares plunged on fears that Anthropic’s new AI tools render legacy enterprise software obsolete — amplifying broader investor unease over Trump’s 15% Section 122 tariffs taking effect Feb 24. Financial stocks (AmEx, Goldman, JPMorgan) led the Dow’s decline. The S&P is now down roughly 5% since Trump announced the tariff escalation Feb 21.

Feb 21 — 9:00 AM PT: Less than 24 hours after signing a 10% global tariff under Section 122, Trump announced a further escalation to 15% — “effective immediately” — via a social media post Saturday morning. The move comes one day after the Supreme Court struck down his IEEPA emergency tariffs as unconstitutional. Trump offered no additional details on exemptions or affected countries, stating only that many nations had been “ripping” the US off “for decades without retribution.” The jump from 10% to 15% is a 50% rate increase in a single day. The financial and trade fallout is still developing. (Sources: CP24, Spectrum News, DW, CTV)

Feb 21 — 10:00 AM PT: Key details on the 15% tariff now confirmed. Section 122 of the 1974 Trade Act legally caps the tariff at 15% — Trump has hit the statutory ceiling. The tariff also automatically expires in 150 days unless Congress votes to extend it, setting up a potential legislative showdown around mid-July 2026. CUSMA-compliant goods from Canada and Mexico are exempt, as are existing sector tariffs on steel, aluminum, and automobiles (unaffected by the SCOTUS ruling). Meanwhile, US Trade Representative Jamieson Greer announced the administration will now launch Section 301 investigations against trading partners — a separate legal mechanism that allows tariff actions if a country’s policies are found “unreasonable and discriminatory.” Section 301 investigations take months and include a public comment period, meaning a new round of higher, country-specific tariffs could arrive by late 2026.

What Is Section 122 — The Never-Used Law Trump Just Activated?

Section 122 of the Trade Act of 1974 has been sitting dormant in US law for over 50 years. No president had ever used it — until tonight. The statute authorizes the president to impose a temporary import surcharge of up to 15% when the country faces a “large and serious United States balance-of-payments deficit.” It was written for a Nixon-era world of fixed exchange rates and current account crises. Trump has now weaponized it as a tariff backstop — a ready-made legal authority to replace the IEEPA framework the Supreme Court just invalidated.

The key parameters of Section 122 are meaningfully different from IEEPA. Under IEEPA, the president had open-ended emergency authority and no statutory tariff ceiling. Under Section 122, the ceiling is 15% and the timer starts the moment the tariffs kick in. The White House proclamation set the rate at 10% — leaving 5 percentage points of legal headroom if Trump decides to escalate before the 150-day window closes.

Legal scholars are divided on whether Section 122 actually authorizes what Trump is doing. The statute requires a “large and serious” balance-of-payments deficit — a technical economic condition, not simply a trade deficit or a presidential preference. Critics argue the US trade deficit, while large, doesn’t meet the statutory threshold for balance-of-payments emergency. Supporters argue the president has broad discretion to make that determination. The courts will decide — but unlike the clear IEEPA ruling, this one is genuinely uncertain. That uncertainty is the point.

What the New 10% Global Tariffs Actually Cost You

The 10% global tariff applies to most imports worldwide starting February 24. That means higher prices on a staggering range of products — clothing, electronics, appliances, furniture, auto parts, and a large share of grocery staples that Americans buy every week. The Yale Budget Lab estimates that tariffs at this scale could cost the average US household between $1,900 and $2,400 per year in higher prices — a direct tax on consumption paid disproportionately by lower- and middle-income households.

Millennials and Gen Z — already locked out of homeownership and carrying the weight of $1.7 trillion in student debt — spend a higher percentage of their income on consumables than older, wealthier generations. A flat 10% tariff is structurally regressive: it hits harder the less money you have. A Boomer with a paid-off home and a fixed pension absorbs a tariff differently than a 31-year-old renting a one-bedroom and buying store-brand pasta.

What’s exempted: USMCA-compliant goods from Canada and Mexico, critical minerals, energy products, pharmaceuticals, some agricultural products (beef, tomatoes, oranges), passenger vehicles and parts, and certain electronics and aerospace components. What’s not exempted: the vast majority of consumer goods that fill American households. The exemptions protect industries and supply chains — not grocery carts.

The 150-Day Clock: What Happens When It Runs Out?

Section 122’s tariff authority expires after 150 days — by design. The statute was written as a temporary emergency tool, not a permanent trade policy mechanism. That means the clock starts February 24 and runs out around late July 2026. At that point, Congress must affirmatively authorize an extension, or the tariffs lapse automatically.

This is the crux of the political calculation. With midterm elections approaching in November 2026, the 150-day window forces a congressional vote on tariff extension right in the heart of campaign season. Republican members from swing districts — particularly in states with heavy import exposure like Michigan, Ohio, and Pennsylvania — will face direct constituent pressure from manufacturers, retailers, and consumers all feeling the price increases. The timing is not an accident, and it’s not comfortable for anyone who has to run for re-election on it.

There’s also the question of what happens to IEEPA tariffs already paid. The Supreme Court ruling in Learning Resources did not explicitly bar importers from claiming refunds on tariffs collected under the invalidated IEEPA authority. The Yale Budget Lab has flagged this as a live issue — smaller importers paid billions in tariffs that may now be legally recoverable, creating a massive administrative and fiscal headache regardless of what Section 122 does going forward.

The SCOTUS Ruling Didn’t Stop Him — It Just Changed His Paperwork

The larger lesson of today is one the political class has been learning in slow motion: judicial rulings slow executive action, they don’t stop it. The Supreme Court took months to hear Learning Resources, months to deliberate, and delivered its ruling on a Friday afternoon. By Friday evening, the tariffs were back — under a different statute, with a different legal justification, and with a head start of roughly six hours before the first legal challenge was filed.

Chief Justice Roberts’ majority opinion in Learning Resources specifically noted that Congress had given the president clear tariff authority in specific statutes — and that IEEPA wasn’t one of them. Section 122 is one of them. Trump’s legal team had apparently been preparing the Section 122 proclamation as a contingency for weeks. The speed of the pivot — from SCOTUS ruling to new executive order in under four hours — suggests this was not improvisation. It was a pre-loaded backup plan waiting for the trigger.

The net result for consumers: tariff-driven price increases that were theoretically stopped today will largely continue. The S&P 500 closed up 0.7% on the SCOTUS ruling — a brief exhale of relief from markets that understood the IEEPA tariffs were on borrowed legal time. By tonight, much of that relief had evaporated as the Section 122 order landed. The tariff war on your wallet just got a new legal address. It’s still at the same house.

The Counter-Argument: ‘Tariffs Will Bring Jobs Back’

The White House proclamation justifying the Section 122 tariffs argues they will “incentivize domestic production,” “correct the balance-of-payments deficit,” and ultimately “lower costs for consumers” by rebuilding American manufacturing. The argument is not entirely without merit — and it deserves a straight answer.

Tariffs can, under the right conditions, help domestic industries survive foreign competition — particularly industries targeted by state subsidies or currency manipulation from trade rivals like China. Steel, aluminum, and certain semiconductor supply chains are legitimate examples where strategic tariffs have supported domestic capacity. That’s real.

The problem is the mechanism and the timeline. A blanket 10% global tariff doesn’t discriminate between predatory Chinese dumping and Canadian lumber or Vietnamese apparel. It raises prices on everything immediately — today — while the promised manufacturing renaissance, if it comes at all, takes years to materialize. And historically, broad tariff regimes have not produced the promised employment gains. The 2018 steel tariffs saved an estimated 8,700 steel jobs while costing roughly 75,000 jobs in steel-consuming industries, according to the Peterson Institute for International Economics. Millennials and Gen Z don’t get to wait for the long-run benefits while they’re paying the short-run price hike at the register today.

Frequently Asked Questions

What is Section 122 and why can Trump use it for tariffs?
Section 122 of the Trade Act of 1974 authorizes the president to impose a temporary import surcharge of up to 15% for up to 150 days when the US faces a “large and serious balance-of-payments deficit.” Unlike IEEPA — which the Supreme Court ruled doesn’t explicitly grant tariff authority — Section 122 is an explicit tariff statute, making it harder to challenge on the same constitutional grounds. No president had used it before Trump signed the February 20 proclamation.

When do the new Section 122 tariffs take effect and how long do they last?
The new 10% global tariffs take effect February 24, 2026 at 12:01 a.m. EST. They are legally limited to 150 days — expiring around late July 2026. After 150 days, Congress must authorize an extension or the tariffs lapse automatically.

What goods are exempt from the new 10% tariffs?
Key exemptions include USMCA-compliant goods from Canada and Mexico, energy products, critical minerals, pharmaceuticals, some agricultural products (beef, tomatoes, oranges), passenger vehicles and parts, and certain electronics and aerospace components. Most other consumer goods — clothing, appliances, furniture, electronics accessories, and a large share of grocery products — are subject to the 10% surcharge.

Can I get a refund on IEEPA tariffs already paid?
Possibly. The Supreme Court’s ruling in Learning Resources, Inc. v. Trump struck down the IEEPA tariffs but did not explicitly bar refund claims for tariffs already collected. The Yale Budget Lab has flagged this as a live legal question. Importers who paid IEEPA tariffs may have grounds to claim refunds — though the administrative process is complex and smaller firms may face significant obstacles.
