Trump Signs Tariff with Section 232 Targets

On March 8, 2018, President Trump signed a tariff with Section 232 targets.

The tariffs were specifically aimed at imported steel and aluminum products.

The tariffs were set at 25% for steel and 10% for aluminum, with some countries exempted.

These tariffs were imposed under Section 232 of the Trade Expansion Act of 1962, which allows the president to impose tariffs based on national security concerns.

The tariffs were implemented to protect American industries and jobs, particularly in the steel and aluminum sectors.

The Trump Administration's trade policy was marked by a series of unprecedented moves, including the use of tariffs as a tool for national security and trade deficits. Trump leveraged Section 232 of the Trade Expansion Act to impose tariffs on steel, aluminum, and auto imports, and declared multiple "national emergencies" under the National Emergencies Act and the International Emergency Economic Powers Act to enact tariffs quickly.

The administration's actions were met with criticism from many economists and legal experts, who argued that the idea of an emergency was being used to justify sweeping import duties without regard to congressional approval or international trade rules. The New York Times reported that many saw this as an attempt to bypass Congress and international trade rules.

The Trump tariffs had significant effects on trade, particularly with China. The tariffs, combined with the impacts of COVID-19, led to a decline in trade between China and the US in 2019 and 2020. However, trade between the two countries subsequently rebounded, and by 2021, merchandise trade was down only marginally from its record high in 2018.

In December 2024, Trump appointed Peter Navarro as his Senior Counselor for Trade and Manufacturing, a position he had previously held during Trump's first term.

Navarro had been recently imprisoned for defying congressional subpoenas related to his role in attempts to overturn the 2020 United States presidential election.

He advocates for a permanent regime of trade barriers to balance the trade deficit and has written books criticizing corporations for prioritizing profits over American jobs.

Navarro began working closely with cabinet nominees Howard Lutnick and Jamieson Greer in Trump's second term, facing less opposition than in his first term.

In November 2024, Stephen Miran, now chairman of the Council of Economic Advisers under Trump, released a white paper titled "A User's Guide to Restructuring the Global Trading System".

Miran's white paper proposed using tariffs as a tool to drive down the value of the dollar through a negotiated 'Mar-a-Lago Accord'.

The administration's ultimate tariff formula did not closely resemble any of Miran's suggestions, but the underlying ideas in his white paper remain important in the Trump administration's conduct of trade policy.

Section 232 is a provision of the Trade Expansion Act that allows the President to modify imports if the Secretary of Commerce conducts an investigation, holds public hearings, and determines that the imports threaten national security.

In his second term, Trump used Section 232 to impose tariffs on steel, aluminum, and auto imports. He directed the USTR to initiate similar investigations to impose tariffs under this section.

Trump's use of Section 232 was unprecedented, and it allowed him to impose tariffs quickly without following the complex procedures required by other trade statutes.

Steel and aluminum were the first targets of Trump's tariffs, with a 25% tariff imposed on all imports in March 2025.

The US imported 44% of its aluminum and 26% of its steel in 2023, with Canada being its largest supplier of both.

Canada was temporarily exempted from the steel and aluminum tariffs, but became subject to them on May 31, 2018.

Copper imports were also targeted, with a 50% tariff imposed on July 9, 2025, and Chile being the largest supplier of US copper imports.

The US was the world's largest producer of aluminum through 2000 but accounted for less than 2% of the global supply by 2021 due to high electricity costs.

Automobiles and auto parts were also subject to tariffs, with a 25% tariff imposed on imported cars and parts on April 3, 2025.

South Korea was exempted from steel tariffs but imposed an import quota of about 2.68 million tons.

BMW chose to cover the tariffs on non-USMCA compliant brands manufacturing in Canada or Mexico until May 1, 2025.

The USMCA exemption closed on April 3, 2025, and the White House argued the move would boost domestic manufacturing and generate $100 billion in tax revenue.

Steel and aluminum tariffs have been a significant focus of trade policies in the US. The US imposed 25% tariffs on all steel and aluminum imports on March 12, 2025, aiming to strengthen domestic production.

In 2023, the US imported 44% of its aluminum and 26% of its steel, with Canada being its largest supplier of both. Canada accounted for more than half of aluminum and two-thirds of primary aluminum imports.

The US was the world's largest producer of aluminum through 2000 but accounted for less than 2% of the global supply by 2021. This decline was largely due to high electricity costs making it less competitive in the global market.

Primary aluminum smelters operated at 55% capacity in the US compared to 95% in Canada and 88% globally in 2021.

The tariffs imposed on copper imports are expected to increase the prices of U.S. products containing copper components, affecting various industries.

Copper producers with major operations in the U.S., such as Freeport-McMoRan and Rio Tinto, are likely to be impacted by the tariffs.

Chile supplies about 60% of U.S. copper imports, with Chilean state-owned miner Codelco sending roughly one-third of its copper exports to the United States.

The tariffs were initially expected to have a negative effect on Chile, including reduced employment, diminished foreign investment, and lower government revenues.

However, the exception made for cathode copper, which represents 11.1% of the value of Chilean copper exports, has improved the outlook for Chilean mining, particularly for Codelco.

Here are some key facts about the copper tariffs:

The USMCA exemption for tariffs on imported cars from Mexico and Canada closed on April 3, 2025, with President Trump imposing a 25% tariff on all imported cars.

Economist Arthur Laffer estimated that car prices would increase by $4,711 due to the tariffs, compared to $2,765 if the USMCA exemption remained available.

Stellantis temporarily closed factories in Canada and Mexico and laid off 900 American employees as it assessed the impact of tariffs.

In May 2025, US automakers criticized Trump's trade deal with the UK for making it cheaper to buy a British car than one assembled in Mexico or Canada using US parts.

Ford CEO Jim Farley warned investors that a 25% tariff across the Mexico and Canadian border would "blow a hole in the US industry that we have never seen."

BMW chose to cover tariffs on non-USMCA compliant vehicles until May 1, 2025.

The 25% tariff on imported cars was extended to auto parts on May 3, 2025, but exempted parts made in Mexico or Canada that were compliant with the USMCA.

President Trump provided a rebate on a proportion of tariffs paid for the next two years.

A 25% tariff on imported cars from Mexico and Canada was imposed on all imported cars, including those from Mexico and Canada, on April 3, 2025.

Trump threatened to impose 100% tariffs on Russia if there was no peace deal with Ukraine within 50 days, later reducing the deadline to "10 or 12 days" on July 29, 2025.

China placed retaliatory tariffs on U.S. goods in response to the Section 232 investigation.

The Chinese government threatened to curb imports of U.S. soybeans.

China imposed tariffs on U.S. exports, with an average tariff rate of 20.7% by June 2019.

This is significantly higher than the 8% average tariff rate imposed on all countries in January 2018.

Here's a breakdown of the countries that were subject to China's higher tariffs:

China's retaliatory tariffs were a direct response to the U.S. tariffs imposed on Chinese goods.

The U.S. tariffs were part of the Section 232 investigation into imports of semiconductors and semiconductor manufacturing equipment.

On September 29, 2025, Trump announced 10% tariffs on imports of softwood timber and lumber.

These tariffs will take effect on October 14, 2025.

In addition to softwood timber and lumber, 25% tariffs were also announced on kitchen cabinets, bathroom vanities, and upholstered furniture.

The USMCA exemption closed on April 3, 2025, when Trump imposed a new 25% tariff on all imported cars, including those from Mexico.

This move affected non-USMCA compliant brands manufacturing in Canada or Mexico, such as BMW, which chose to cover these tariffs until May 1, 2025.

The White House argued the move would boost domestic manufacturing and generate $100 billion in tax revenue, noting that about 50% of the 16 million cars bought by Americans in 2024 were imported.

The 25% tariff extended to auto parts on May 3, but Trump exempted parts made in Mexico or Canada that were compliant with the USMCA.

In May, US automakers criticized Trump's trade deal with the UK for making it cheaper to buy a British car than one of their cars assembled in Mexico or Canada using US parts.

The "reciprocal" tariff policy was a key part of Trump's trade strategy, aiming to address the US trade deficit.

Trump directed his staff to research trade barriers imposed by foreign countries and develop custom tariffs to counter them. He instructed them to consider existing tariffs, exchange rates, and trade balances in their analysis.

The policy was set to be unveiled on April 2, 2025, with a 10% minimum tariff on nearly all other countries, effective April 5, 2025. A higher tariff rate was planned for 57 countries and territories.

The Office of the United States Trade Representative (USTR) said the "reciprocal tariffs" aimed to "drive bilateral trade deficits to zero". However, even countries with a trade surplus with the US received a tariff of 10%.

Here is a list of countries and their corresponding tariff rates on April 9, 2025:

Economic experts criticized the administration's formula for calculating trade barriers, calling it overly simplistic and unrelated to actual trade barriers.

The Trump tariffs had a significant impact on the global market, causing a global market crash with the S&P 500 Index falling over 274 points or 4.88%. The Nasdaq Composite fell over 1,050 points or 5.97%, the largest point loss in its history.

Market volatility continued as the 10% base tariff took effect and China began to retaliate. The bond market also began selling off in a scenario called bond vigilantism.

Stocks surged within minutes of the pause announcement, with the S&P 500 rising 9.52% for its largest one-day gain since 2008. The tariffs were delayed first to August 1 and then to August 7, when they finally took effect.

The disruption led to lower prices, storage shortages due to oversupply, and financial strain on American farmers, prompting political pressure for a resolution and efforts to diversify export markets.

The market crash that occurred in response to the reciprocal tariff announcement was a significant event, with the S&P 500 Index falling over 274 points or 4.88% in a single day.

This was the second largest daily point loss ever recorded, and it was followed by a continued market volatility as the 10% base tariff took effect and China began to retaliate.

The bond market also started selling off in a scenario called bond vigilantism, with the head of FX at Deutsche Bank describing it as a "simultaneous collapse in the price of all US assets".

The situation was so dire that Trump announced a 90-day pause on reciprocal tariffs above 10% for all countries except China, which had increased its minimum tariff rate to 145%.

This pause was meant to provide time for bespoke negotiations with each country, and it led to a surge in stocks, with the S&P 500 rising 9.52% for its largest one-day gain since 2008.

The market continued to rise in the following weeks, with the S&P 500 setting a new all-time high on June 27, 2025, after further policy rollbacks.

The administration's credibility was called into question by analysts, who suggested that Trump's threats had lost their impact, and that the administration had only announced three trade agreements by July.

The tariffs were eventually delayed to August 1 and then to August 7, when they finally took effect, but the damage had already been done.

Secondary tariffs were a new trade policy introduced by the second Trump administration, resembling secondary sanctions.

They penalized third-party countries or entities that trade with targeted nations, unlike primary tariffs which directly target a specific country.

In March 2025, Trump signed an executive order imposing a 25% tariff on nations that purchase oil from Venezuela at the Secretary of State's discretion.

The first "secondary tariff" was ordered on India on August 6, 2025, citing authority under the IEEPA, with Indian exports to the US facing an additional 25% tariff starting September 17, 2025.

Secondary tariffs were also threatened on countries purchasing Russian oil and on countries that trade with Iran.

A majority of U.S. senators supported secondary sanctions against Russia in June 2025, which would impose 500% tariffs on countries that buy Russian oil, natural gas, uranium, and other exports.

The impact of secondary tariffs was significant, with trade between the US and targeted countries declining as a result.

The Trump administration's tariffs had a significant impact on China–U.S. trade. American agriculture exports to China declined by 53% from 2017 to 2018, falling from $19.5 billion to $9.1 billion.

China responded to the tariffs by halting imports of all American agricultural goods in August 2019. This move had a ripple effect on the U.S. economy, particularly for farmers.

The tariffs also led to a decline in trade between China and the U.S. in 2019 and 2020. However, trade between the two countries rebounded significantly in 2021, with merchandise trade down only marginally from its record high in 2018.

A survey of U.S. enterprises operating in China in 2021 showed that two-thirds of them were optimistic about the Chinese market and planned to increase their investments in China. This suggests that despite the tariffs, many U.S. businesses remained confident in China's potential.

The tariffs did not seem to have a significant impact on U.S. enterprises leaving China, with less than 1% of the increase in U.S. enterprises leaving China in 2018 and 2019 attributed to the tariffs.

Trade conflicts were a hallmark of Trump's tariff policies. The US imposed 50% tariffs on steel and aluminum from Canada, which prompted intense negotiations and reprisals.

Canada was in a tough spot, but they managed to negotiate a deal with the US. The two countries pledged to work on a deal within 30 days, which they did at the 51st G7 summit.

The deal kept the 10% minimum tariff largely in place, which wasn't a big win for many analysts. Conservative Party leader Kemi Badenoch described it as "better than nothing but it's not much."

US automakers were also unhappy with the deal. They felt it made it cheaper to import a car from the UK than one assembled in Mexico or Canada using US parts.

The tariffs also had a significant impact on US-China trade. The US imposed a 10% tariff on $300 billion of Chinese imports, which led to a major decline in US agricultural exports to China.

US agricultural exports to China fell from $19.5 billion in 2017 to $9.1 billion in 2018, a 53% decline. The decline was largely due to China halting imports of all American agricultural goods in response to the tariffs.

Despite the decline, US enterprises were not deterred from operating in China. In 2021, a survey showed that two-thirds of US enterprises operating in China were optimistic about the market and planned to increase their investments.

The economic impacts of Trump's tariffs have been significant. The unemployment rate has been a major concern, with analysts forecasting that tariffs could push it to recession levels.

Federal data indicates that the manufacturing sector lost a net total of 14,000 jobs in May and June combined. This is a worrying trend, especially since hiring in manufacturing plants slowed to its weakest pace since 2016.

Manufacturing job openings have decreased by about 100,000 since the start of the Trump presidency. This suggests that companies are struggling to adapt to the new trade environment.

On a more positive note, Trump's tariffs have raised a record amount of money from customs and excise taxes. By July 2025, tariffs had raised $108 billion in net revenue in the previous nine months.

This revenue is significant, comprising 5% of federal revenue compared to 2% historically. However, estimates suggest that tariff revenues may not be enough to cover the cost of income taxes, even for those making less than $200,000 per year.

Senators Chuck Grassley and Maria Cantwell introduced the bipartisan Trade Review Act of 2025, proposing amendments to the law aimed at separation of powers and closing legal loopholes.

The law has not yet reached a consensus, with Senate Majority Leader John Thune referring to it dismissively, saying "I don't think that has a future."

Rep. Don Bacon introduced a similar bill in the House of Representatives, stating, "The Constitution clearly gives the authority for taxes and tariffs to Congress. Our Founders created checks and balances for a reason", urging Congress to reclaim its responsibility.

Democratic Senator Adam Schiff called on Congress to investigate whether Trump had engaged in suspicious insider trading or market manipulation when he abruptly announced and paused the tariffs.

Trump's tariffs were described as intentionally vague and without specifics, granting the president greater powers, according to Roll Call.

Trump stated in an interview with CNBC that "The details are $600 billion to invest in anything I want. Anything. I can do anything I want", which University of North Carolina professor Michael Gerhardt described as "quite problematic."

Six in 10 Americans hold the Trump administration responsible for the rising cost of living, according to a survey conducted by Morning Consult for the Century Foundation.

The Trump sign tariff had far-reaching effects on countries around the world.

China was one of the hardest hit, with a 25% tariff imposed on $50 billion worth of Chinese goods, including electronics and machinery.

The European Union also felt the impact, with tariffs imposed on $7.5 billion worth of EU goods, including wine and cheese.

Canada was another country affected, with a 10% tariff imposed on $12.8 billion worth of Canadian goods, including lumber and aluminum.

China's trade policies have had a significant impact on the global economy. The Chinese government imposed retaliatory tariffs on U.S. goods, targeting American exports.

China's tariffs on U.S. goods are notably higher than on other countries. By June 2019, average tariffs on American exports had increased to 20.7%, while those on other countries had declined to 6.7%.

India has a massive population of over 1.3 billion people, making it one of the most populous countries in the world.

The impact of climate change on India is expected to be severe, with temperatures projected to rise by 2-4°C by 2050. This could lead to more frequent and intense heatwaves, droughts, and floods.

India's agriculture sector is highly vulnerable to climate change, with crop yields expected to decline by up to 50% by 2050. This could lead to food shortages and economic losses for farmers.

India has made significant strides in renewable energy, with solar power capacity increasing by over 500% in the last five years. This shift towards clean energy is expected to reduce the country's carbon footprint and contribute to a more sustainable future.

The Himalayan region of India is home to some of the world's most sacred and fragile ecosystems, including the Gangotri Glacier, which is melting at an alarming rate due to climate change.

Singapore was one of the countries affected by Trump's tariff imposition on April 2, 2025, with a 10% tariff on all goods coming from the country.

The response from Singapore's Prime Minister, Lawrence Wong, was swift and vocal, with him stating that the U.S. actions were not reform and would instead accelerate the fracturing of the global economy.

The Singaporean government announced the creation of a national task force to support businesses and workers affected by the tariffs, which held its first meeting on April 16, 2025.

Lawrence Wong also stated that Singapore would not retaliate on U.S. tariffs, despite the imposition of tariffs on their goods.

Singaporean diplomatic efforts led to requests from the country to relieve pharmaceutical exports and seek greater access to advanced semiconductor and AI technologies.

Despite these efforts, Deputy Prime Minister Gan Kim Yong announced on July 3, 2025, that there was a very real chance that the tariffs would stay intact up until the end of the second Trump administration.

South Korea was hit with reciprocal tariffs of 25% on April 2, 2025, by Trump, which led to the South Korean government announcing emergency support for its auto industry.

The South Korean government took a diplomatic approach, with acting president Han Duck-soo calling for negotiation rather than retaliation on April 8, 2025.

A trade deal was eventually reached between the US and South Korea, with Trump announcing on July 30, 2025, that the US would impose 15% tariffs on South Korean goods starting August 1.

The US had previously imposed tariffs on South Korean trucks, which were extended until 2041 as part of the KORUS FTA changes announced on March 28, 2018.

In November 2024 and January 2025, Trump threatened BRICS countries with 100% tariffs if they attempted to replace the US dollar as a reserve currency.

Canada's economy is highly integrated with the US economy, with over 75% of its trade going to the US. This makes Canada particularly vulnerable to the economic impacts of a US-China trade war.

Canada's trade with China is relatively small, but it's still a significant player in the country's economy, accounting for around 5% of its trade. The country's trade with the US is expected to increase as a result of the trade war.

Mexico, on the other hand, is heavily reliant on the US market, with over 80% of its trade going to the US. The country's economy is expected to contract by 1.5% as a result of the trade war.

Mexico's automotive industry is particularly vulnerable to the trade war, with many of its major manufacturers relying on US-made parts. The country's agricultural sector is also expected to be hit hard, with US tariffs on Mexican agricultural products expected to increase.

A fresh viewpoint: Trump Tariff Announcement

The Trump administration's tariff policy was based on several laws, but the main one cited was Section 232 of the Trade Expansion Act of 1962. This section allows the president to impose tariffs based on the recommendation from the U.S. Secretary of Commerce if an article threatens or impairs national security.

However, this section has rarely been used since the World Trade Organization was established in 1995. In fact, the Trump administration's tariffs were imposed without citing national security as the reason, as seen in a tweet by Trump addressing Prime Minister of Canada Justin Trudeau.

The Trump administration claimed that the International Emergency Economic Powers Act (IEEPA) gave them the authority to raise tariffs without limits during a national emergency of any kind. However, legal scholar Gerard Magliocca disagreed, pointing out that the IEEPA does not mention tariffs at all.

A key case that challenged Trump's authority to impose tariffs was V.O.S. Selections, Inc. v. United States, where the United States Court of International Trade (CIT) ruled that Trump had exceeded his authority under the IEEPA. The CIT found that the tariffs were illegal because the triggering emergency bore no rational connection to the trade measures imposed.

Here's a summary of the laws and cases that were used to challenge Trump's tariff policy:
