Mexico Largely Shielded from Potential New US Tariffs, Economy Secretary Says
Mexico City – The vast majority of Mexico’s trade with the United States under the USMCA trade agreement would be unaffected by potential new tariffs stemming from a US investigation into trade imbalances, according to Mexican Economy Secretary Marcelo Ebrard. Speaking on Thursday, March 12, 2026, Ebrard stated that approximately 85% of Mexico’s commerce within the framework of the United States-Mexico-Canada Agreement (USMCA) falls outside the scope of Section 301 of US trade law, the provision Washington is invoking to justify the new inquiries.
The announcement from the administration of US President Donald Trump on Wednesday, March 11, 2026, initiated two new trade investigations. These focus on excess industrial capacity within 16 major trading partners, including Mexico, and concerns regarding forced labor practices. The move signals a renewed push for potential tariffs following a recent Supreme Court decision that significantly curtailed Trump’s previous tariff programs. Ebrard’s comments aim to reassure markets and businesses that the impact on Mexican exports will be limited.
Understanding Section 301 and its Implications
Section 301 of the Trade Act of 1974 allows the United States to investigate and impose tariffs on foreign countries that engage in unfair trade practices. The law has been a frequent tool for the US to address perceived trade imbalances and protect domestic industries. The Trump administration utilized Section 301 extensively, imposing tariffs on goods from China and other nations. However, the Supreme Court recently limited the scope of the administration’s ability to levy tariffs under this provision, prompting the new investigations announced this week. Chapter III of the North American Free Trade Agreement (NAFTA), the predecessor to USMCA, outlines provisions related to national treatment and access to markets, including those concerning tariffs.
The current investigations, spearheaded by US Trade Representative Jamieson Greer, could potentially lead to new tariffs on countries including China, the European Union, India, Japan, South Korea, and Mexico before the end of the northern hemisphere’s summer. The focus on excess industrial capacity suggests the US is concerned about overproduction in these countries potentially harming American manufacturers. The forced labor component of the investigation reflects growing international scrutiny of supply chain ethics and human rights.
USMCA and Mexico’s Trade Position
The USMCA, which replaced NAFTA in 2020, aims to govern trade between the United States, Mexico, and Canada. The official texts of the treaty are available through the Mexican government’s website. Ebrard’s assertion that 85% of Mexican trade is unaffected by the Section 301 investigation is a significant point, suggesting that Mexico has structured its trade relationships to minimize vulnerability to these types of tariffs. This could be due to the specific sectors Mexico focuses on exporting to the US, or the provisions within USMCA itself.
“We continue without tariffs,” Ebrard affirmed during a meeting with reporters, responding directly to questions about the newly announced US investigations. He further expressed confidence that the investigations would not significantly disrupt the overall trade relationship between the two countries. This optimistic outlook is likely based on the understanding that a substantial portion of Mexico’s exports fall outside the areas targeted by the Section 301 review.
Potential Impacts and Industry Reactions
While Ebrard’s statement offers a degree of reassurance, the remaining 15% of Mexican trade potentially subject to these investigations warrants close monitoring. Industries within that segment, such as those involved in specific manufacturing sectors or those facing accusations of unfair trade practices, could face increased scrutiny and potential tariff burdens. The specific details of the investigations and the criteria used to determine whether tariffs will be imposed remain unclear.
The investigations into excess industrial capacity could particularly affect sectors where Mexico has significantly increased its production in recent years, potentially competing directly with US manufacturers. Similarly, the focus on forced labor practices will likely lead to increased due diligence requirements for companies sourcing goods from Mexico, ensuring compliance with ethical labor standards. The US government has been increasingly vocal about its commitment to combating forced labor in global supply chains.
Looking Ahead
The coming months will be crucial as the US Trade Representative conducts its investigations and assesses the potential for imposing tariffs. Mexico will likely engage in diplomatic efforts to present its case and advocate for a minimal impact on its trade relationship with the United States. Businesses on both sides of the border should prepare for potential disruptions and consider diversifying their supply chains to mitigate risks.
The next key development will be the release of preliminary findings from the US Trade Representative’s investigations, expected in the late spring of 2026. These findings will provide a clearer indication of which sectors are most likely to be affected and the potential magnitude of any tariffs that may be imposed. Stakeholders should closely monitor official announcements from the US Trade Representative’s office and the Mexican Economy Secretariat for updates.
This situation underscores the ongoing complexities of international trade and the importance of maintaining open communication and collaboration between trading partners. The USMCA, while designed to foster greater economic integration, does not eliminate the potential for trade disputes and the leverage of protectionist measures. The outcome of these investigations will have significant implications for the future of US-Mexico trade relations.
