Since taking office on January 20, the U.S. President has issued a series of Executive Orders (“EOs”) declaring national emergencies with regard to drug and human trafficking and other criminal behavior in North America, as well as worldwide trade imbalances, and imposing tariffs (collectively, the “2025 Tariffs”). Since then, the tariffs have been the subject of litigation, attempted Congressional action, and economic debate.
Executive Orders and Actions Timeline for the 2025 Tariffs: Canada and Mexico
February 1: The U.S. President issued two EOs declaring states of emergency with regard to the northern border with Canada and the southern border with Mexico and imposing 25% tariffs on imports from Canada and Mexico (EOs 14193 and 14194). Energy and energy resources were only subjected to 10% tariffs.
The EOs invoked the International Emergency Economic Powers Act of 1977 (“IEEPA”) to impose the additional tariffs. There was explicitly no de minimis carveout. Both EOs also stated that the tariffs and their scope might be increased or expanded if Canada or Mexico imposed retaliatory tariffs on imports from the United States.
The justification cited for the import tariffs on goods from Canada was “failure of Canada to do more to arrest, seize, detain, or otherwise intercept [drug trafficking organizations], other drug and human traffickers, criminals at large, and drugs.” The justification for the Mexican import tariffs on goods from Mexico was identical, except that it targeted “illicit drugs” rather than all drugs.
February 3: Tariffs were paused until March 4 in recognition of the governments of Canada and Mexico taking “immediate steps designed to alleviate the illegal migration and illicit drug crisis through cooperative actions” (EOs 14197 and 14198).
March 2: De minimis import tariffs from Canada and Mexico were paused (EOs 14226 and 14227). Historically, de minimis imports have been duty-free to avoid administrative expense and inconvenience disproportionate to the revenue that would be collected.
March 6: Eliminated tariffs for all imports from Canada and Mexico that were duty-free under the existing United States-Mexico-Canada Agreement (“USMCA”) (EOs 14231 and 14232). The reason cited for the tariff adjustment was the employment and innovation that the automotive production industry brings to the United States. The duty on potash, used to make agricultural fertilizer, was also reduced from 25% to 10%.
April 2: Imports from Canada and Mexico were exempted from a new general 10% tariff on “all imports from all trading partners” worldwide, plus an additional 11–50% on imports from a list of fifty-seven countries, imposed in response to concerns cited about trade deficits and lack of reciprocity in bilateral trade relationships (EO 14257). The EO similarly invoked IEEPA to impose the tariffs.
No additional tariffs were imposed on Canada and Mexico. However, the EO provides that if the tariffs already imposed this year are terminated or suspended, there would be a 12% tariff on imports not eligible for special treatment under the USMCA with the following exceptions: energy and energy resources, potash, and parts or components of “an article substantially finished in the United States.”
July 12: The U.S. President posted a letter on social media to the President of Mexico announcing a 30% tariff would go into effect on August 1.
July 30: The de minimis tariff exemption for goods shipped for consumption was suspended globally, including for imports from Canada and Mexico (EO 14324). Effective August 29, the IEEPA-related tariffs apply, plus a specific duty per package ranging from $80 to $200 per item.
July 31: The U.S. President announced on social media that there would be a ninety-day delay on the Mexico tariffs. By contrast, tariffs on imports from Canada were increased from 25% to 35%, with the EO citing “Canada’s lack of cooperation in stemming the flood of fentanyl and other illicit drugs across our northern border” (EO 14325). An additional 40% tariff rate was also applied to goods “transshipped to evade applicable duties.” The tariffs were effective August 1.
Litigation
The 2025 Tariffs have been challenged in numerous courts, including the U.S. Court of International Trade (“CIT”). On May 28, the CIT in V.O.S. Selections, Inc. v. Trump vacated the orders for what it referred to as the “Trafficking Tariffs” and the “Worldwide and Retaliatory Tariffs,” holding that IEEPA did not authorize imposing them, and granted a permanent injunction. The plaintiffs are five businesses that make or import products including wine and spirits, water line pipes, children’s learning kits, fishing gear, and cycling clothing, as well as twelve states. The injunction was stayed pending appeal.
Subsequently, on August 29, the U.S. Court of Appeals for the Federal Circuit (“Federal Circuit”) affirmed the CIT’s holding, but vacated the universal injunction and remanded the case to the CIT to reevaluate whether there was irreparable harm and, if so, the proper scope of any injunctive or other relief.
Also, on May 29, in Learning Resources, Inc. v. Trump, the U.S. District Court for the District of Columbia (“DDC”) found that jurisdiction over the tariffs was not exclusive to the CIT because the tariffs were based on IEEPA authority. The DDC granted a preliminary injunction only as to the two plaintiffs, which are companies that make children’s educational toys. The injunction was stayed pending appeal in the U.S. Court of Appeals for the District of Columbia.
Legal Analysis
Taxation and the Separation of Powers
Tariffs are a tax paid by businesses and consumers that import goods from other countries. The U.S. Constitution grants Congress the exclusive power to impose and collect taxes and duties as well as to regulate commerce with foreign nations (Article I, Section 8, Clauses 1 and 3).
Congress has periodically delegated limited authority to impose tariffs to the President—for example, with regard to administration of tax collection. Under certain circumstances, the President has also been granted the authority to adjust tariffs by international trade agreements that are approved by Congress. However, in each case the statutory grant of authority has imposed clear limitations, and IEEPA contains no such delegation.
International Emergency Economic Powers Act
IEEPA gives the President the authority to declare a national emergency in response to an “unusual and extraordinary threat” to the “national security, foreign policy, or economy of the United States.” The threat must have “its source in whole or substantial part outside the United States,” and the exercise of authority must “deal with” the threat.
This is the first time that IEEPA has been used as a basis for imposing tariffs. The U.S. Department of the Treasury’s Office of Foreign Assets Control (“OFAC”) has interpreted and administered IEEPA and other sanctions laws to impose targeted economic and trade sanctions against named countries, individuals, and organizations since its creation in 1950. Regulations issued under IEEPA Section 1702 generally include instructions to block or license transactions as opposed to imposing a tax or a fee.
The authority to tax is not listed in the enumerated IEEPA powers. All three courts that have ruled on the 2025 Tariffs considered the meaning of the authority to “regulate . . . importation” that is enumerated in Section 1702 and concluded that the 2025 Tariffs exceeded the President’s authority.
The rulings so far have suggested the power to “regulate . . . importation” in IEEPA would be better interpreted consistent with historic context. For example, it might be deemed authority to “fix or adjust the time, amount, degree, or rate of” transactions as in the third meaning of regulate in the Merriam-Webster dictionary.
IEEPA was also intended to be more limited in scope and have more procedural limitations than the Trading with the Enemy Act (“TWEA”) that had been the primary basis for economic and trade sanctions prior to IEEPA’s enactment in 1977. All three courts expressed concerns about the lack of limitations on the 2025 Tariffs, for example on scope, magnitude, and duration. The procedural limitations of IEEPA also include being subject to the National Emergencies Act of 1976 (“NEA”), which requires reporting to Congress and gives Congress the authority to terminate a national emergency declared by the President.
An additional consideration is that there is no direct nexus between the 2025 Tariffs and stopping illicit drug transactions, human trafficking, or criminal activity. IEEPA requires that the sanctions “deal with an unusual and extraordinary threat with respect to which a national emergency has been declared . . . and may not be exercised for any other purpose.” If the intent of the tariffs is to raise taxes, then they are not being imposed for the purpose of dealing with those threats. And while they may make those transactions more expensive, they do not stop them, change their legal status, or bring the perpetrators to justice as enforcement of other existing laws might do.
United States v. Yoshida
The government relied in its arguments on the precedent in United States v. Yoshida International, a 1975 U.S. Court of Customs and Patent Appeals (“CCPA”) decision upholding a 10% import surcharge imposed for five months by President Nixon in August 1971. As described in the DDC decision, the tariffs were only imposed on “goods already subject to tariff reductions,” so the surcharges “did not exceed the original statutory maximum set out by Congress.”
Importantly, the 10% import surcharge at issue in Yoshida was adopted in response to a balance of payments deficit, which is not the same as a trade deficit. At the time, the U.S. dollar had a fixed exchange rate with gold at $35 per ounce. The exchange rate was set in accordance with the international Bretton Woods Agreement signed by forty-four countries in 1944 and adopted by Congress in 1945.
In August 1971, the U.S. government did not have sufficient gold reserves to cover the dollars in circulation around the world. So President Nixon suspended the “gold standard,” and other countries could not exchange dollars for gold at a fixed rate. The import surcharges were a temporary measure in anticipation of exchange rate fluctuations.
In March 1973, the United States and other countries instituted floating exchange rates, so that issue is now moot.
Pending Supreme Court Litigation
On September 9, the U.S. Supreme Court agreed to consider consolidated expedited appeal of the V.O.S. Selections and Learning Resources cases. Oral argument is scheduled for the first week of November, and it is anticipated that the Supreme Court will rule on the validity of the tariffs. If they are invalidated, the government may have to refund the tax revenue.
The 2025 Tariffs will remain in place in the interim unless the President rescinds them or Congress acts sooner.
Congressional Action
Congress can terminate an emergency declared under the National Emergencies Act of 1976 with a joint resolution that has sufficient support to survive a Presidential veto. There have been numerous bills related to the 2025 Tariffs introduced in both the U.S. Senate and the U.S. House of Representatives. Among them:
- Senate Joint Resolution 37 to terminate the national emergency with regard to Canada declared on February 1, 2025, passed the Senate on April 2, 2025, by a vote of 51–48, but it has not been acted on in the House.
- Senate Joint Resolution 49 to terminate the national emergency declared on April 2, 2025, in justification for the Worldwide Tariffs was narrowly defeated on April 30 by a vote of 49–49.
- Bipartisan companion bills S. 1272 and H.R. 2665 have been introduced that would subject import duties under the Trade Act of 1974 to a forty-eight-hour notification requirement and a maximum period of sixty days unless Congress approves or disapproves them by joint resolution.
The draft Joint Resolutions that would terminate the national emergencies were voted on prior to the CIT, DDC, and Federal Circuit decisions. A carefully phrased preamble to a joint resolution that takes into account other existing laws more appropriate to address the challenges facing the United States, as well as the economic impact of the tariffs, could bring broad bipartisan support.
Tax Revenue and Economic Developments
According to U.S. Department of the Treasury data, tariffs generated approximately $165 billion in tax revenue this year as of September 9, which is already an increase of almost $90 billion more than the amount for the entire 2024 calendar year. However, tariffs are intended to reduce imports. So over time, tariff revenue should decrease.
Capital-intensive industries in particular have faced extraordinary tax increases as a result of the 2025 Tariffs. For example, U.S. auto manufacturers Ford Motor Company and General Motors issued company statements forecasting that they will pay approximately about $2 billion and up to $5 billion respectively this year as a result of the tariffs.
Preliminary Bureau of Labor Statistics (“BLS”) data shows that manufacturing jobs decreased by 33,000 between January and August. There are also other increasing signs of economic harm.
According to BLS, the annualized inflation rate increased from a 2025 low of 2.3% in April to 2.9% in August. The unemployment rate increased from 3.7% in January to 4.3% in August.
Conclusion
The 2025 Tariffs have been imposed in a series of EOs carried out mercurially in an extraordinarily compressed timeframe. They have damaged international relations, made it impossible to conduct business with any certainty, and been the subject of successful legal challenges. They have also created artificial price inflation for businesses and consumers and appear to be causing economic harm to the U.S. economy.
Costs from the 2025 Tariffs increase every day, as do the economic disruptions and distortions. Other existing laws such as anti-money laundering, narrowly tailored sanctions with regard to named individuals or organizations, and criminal laws are more appropriate to address concerns with illicit drugs, human trafficking, and criminal behavior.
Trade agreements are carefully crafted during multiyear negotiations because they are a balance of economic interests. Those years allow input from stakeholders, including governments, businesses, and consumer groups. They also allow time for stakeholders to adjust, plan, budget, negotiate or renegotiate mutually beneficial business agreements, establish infrastructure, and arrange financing.
Canada and Mexico are the closest trading partners to the United States both geographically and by trade volume. The USMCA covers both tariff and nontariff barriers, and it just came into force in 2020. Its predecessor, the North American Free Trade Agreement (“NAFTA”), was in place for twenty-six years.
The USMCA is the appropriate mechanism for addressing any trade imbalances and trade disputes. To the extent there are any adjustments that need to be made, the USMCA is scheduled for joint review on July 1, 2026.
Advance consultations are already beginning. On September 16, the Office of the United States Trade Representative (“USTR”) issued a request for comment and scheduled a public hearing for November 17.
