President Donald Trump is dramatically expanding his trade agenda despite a Supreme Court decision that appeared to limit his tariff authority earlier this yr. By turning to an almost century-old law that has never been used before, the administration is signaling that aggressive tariffs remain a centerpiece of U.S. economic policy.
The move could have significant implications for investors, businesses, supply chains, and America’s largest trading partners as markets brace for an additional wave of worldwide trade uncertainty.
Trump Revives a 95-12 months-Old Tariff Law
After the Supreme Court ruled in February that the International Emergency Economic Powers Act (IEEPA) didn’t give the president unlimited authority to impose tariffs, many analysts believed the White House’s most aggressive trade strategy had reached its limit.
As an alternative, the administration quickly pivoted.
President Trump announced plans to invoke Section 338 of the Smoot-Hawley Tariff Act of 1930, a rarely discussed provision that authorizes tariffs against countries found to discriminate against U.S. commerce.
The law has existed for nearly a century but has reportedly never been utilized by any previous president.
Trump’s first goal is Canada, with the administration proposing a 50% tariff under the statute.
A Growing List of Latest Tariffs
The Section 338 motion is barely one a part of a wider trade offensive.
Over the past two weeks, the administration has proposed or announced:
- 50% tariffs on certain Canadian goods
- 25% tariffs targeting Brazil
- As much as 200% tariffs on generic pharmaceutical imports
- Latest tariffs starting from 10% to 12.5% affecting as many as 60 trading partners
The strategy demonstrates that even after the Supreme Court limited one legal pathway, the administration intends to proceed pursuing tariffs through quite a few other statutes already on the books.
Why the Supreme Court Didn’t Stop Trump’s Trade Agenda
The Supreme Court concluded earlier this yr that Congress never explicitly authorized the president to impose broad tariffs under IEEPA.
Moderately than ending Trump’s trade agenda, the ruling effectively redirected it.
The administration has increasingly relied on several existing trade laws, including:
- Section 122 for temporary universal tariffs
- Section 232 for national security-related tariffs
- Section 301 targeting unfair foreign trade practices
- Section 338, the newly revived Depression-era authority
Trade experts note that while a few of these statutes require lengthy investigations, Section 338 allows the administration to maneuver way more quickly.
That flexibility could make it considered one of the administration’s preferred tools moving forward.
Trade Experts Warn More Countries Could Be Targeted
Several trade analysts imagine Canada may only be the start.
Sarah Bianchi, a former Biden administration trade official now with Evercore ISI, suggested the European Union may very well be amongst the following major targets if the White House successfully uses Section 338 as leverage.
Meanwhile, veteran trade attorney John Veroneau questioned whether the law even matches today’s circumstances.
Under the U.S.-Mexico-Canada Agreement (USMCA), Canada already grants the US preferential treatment compared with many other countries. Critics argue that using Section 338 under those conditions stretches the unique purpose of the statute well beyond what Congress envisioned.
Tariff Revenue Could Still Reach Historic Levels
Although Trump can not depend on IEEPA for sweeping tariffs, analysts imagine the financial impact may remain enormous.
Evercore ISI estimates the newest combination of tariffs could generate roughly $240 billion to $260 billion annually in federal revenue.
While that’s below earlier projections before the Supreme Court ruling, it will still represent roughly thrice the tariff revenue collected before Trump’s return to office.
The administration has repeatedly argued that tariffs can reduce trade deficits, encourage domestic manufacturing, and generate government revenue without raising income taxes.
Critics counter that import duties ultimately increase costs for businesses and consumers while creating uncertainty throughout global supply chains.
Congress Pushes Back on Expanding Presidential Trade Powers
Lawmakers on either side of the aisle have increasingly questioned how much tariff authority Congress has delegated to the chief branch.
Sen. Ron Wyden said Congress should reclaim a bigger role in setting U.S. trade policy, arguing that tariff decisions have develop into too concentrated throughout the White House.
At the identical time, Congress is considering laws that will grant the president additional tariff authority involving Russia and countries purchasing Russian energy.
Some trade policy experts warn the laws could unintentionally give future administrations even broader flexibility to impose tariffs for geopolitical purposes.
What Investors Should Watch
Markets have develop into increasingly sensitive to tariff announcements as investors evaluate the potential impact on inflation, corporate earnings, and global growth.
Key sectors that might see increased volatility include:
- Manufacturing
- Automotive firms
- Pharmaceuticals
- Industrial exporters
- Retailers depending on imported goods
Investors will even be watching whether additional trading partners, including the European Union, develop into targets under Section 338 or other existing trade laws.
With multiple legal avenues still available, the Supreme Court’s ruling appears to have modified the legal strategy behind Trump’s tariffs—but not the administration’s broader commitment to using them as a central economic and geopolitical tool.
Incessantly Asked Questions
Why is Trump using Section 338?
Section 338 of the Smoot-Hawley Tariff Act allows the president to impose tariffs against countries that discriminate against U.S. commerce. Even though it has existed since 1930, it has reportedly never been used before.
Didn’t the Supreme Court block Trump’s tariffs?
The Supreme Court ruled that the International Emergency Economic Powers Act (IEEPA) doesn’t provide broad authority for tariffs. Nonetheless, it didn’t prohibit the usage of other trade laws, allowing the administration to pursue different legal authorities.
Which countries could face additional tariffs?
Canada has already been targeted under the brand new strategy. Trade analysts imagine additional actions could eventually include the European Union and other major U.S. trading partners.
How could the brand new tariffs affect investors?
Higher tariffs can influence inflation, corporate profits, supply chains, and global trade flows. Firms that rely heavily on imported materials or international manufacturing may face greater cost pressures if additional tariffs are implemented.
