"Unpacking the U.S.-Mexican Tomato Suspension Agreement and its Ripple Effects on Consumers"


The price and availability of fresh produce are often taken for granted, but a closer look reveals a complex web of international trade agreements that significantly influence what ends up on our plates. One such agreement, the U.S.-Mexican Tomato Suspension Agreement, has been a source of ongoing debate and economic impact for consumers and producers alike.

Tomatoes are a vital export for Mexico, ranking as its second most valuable agricultural commodity. For decades, trade relations between the United States and Mexico have been strained over concerns about unfair trade practices. U.S. growers, particularly in Florida, have long alleged that Mexican tomatoes are being "dumped" on the U.S. market—sold at prices below the cost of production—harming domestic producers.

In response to these concerns, the U.S. and Mexico have engaged in a series of agreements aimed at managing the flow of tomatoes across their borders. These agreements, known as Suspension Agreements, set minimum prices for Mexican tomatoes entering the U.S. While intended to protect U.S. growers, these policies have far-reaching consequences, affecting prices, production, and consumption patterns in both countries, as well as in Canada.

The Scale of U.S.–Mexico Tomato Trade

The Tomato Suspension Agreement (TSA) between the United States and Mexico has long shaped the flow of fresh tomatoes across the border, balancing fair competition with consumer access to affordable produce. On April 14, 2025, the U.S. Department of Commerce gave 90 days' notice of its intent to withdraw from the 2019 Agreement Suspending the Antidumping Duty Investigation on Fresh Tomatoes from Mexico, terminate that agreement, and institute an antidumping duty investigation. The original Tomato Suspension Agreement entered into force in 1996 and suspended an antidumping investigation initiated by the Department of Commerce in response to a petition filed by U.S. tomato growers and packers alleging that Mexican growers were selling their tomatoes at prices below fair value. The termination of this agreement represents a major shift in tomato trade policy with potentially significant consequences for both producers and consumers.

How the TSA Regulates Trade

The Tomato Suspension Agreement regulates U.S.–Mexico tomato trade through mechanisms such as price floors and inspections. These tools were designed to prevent Mexican tomatoes from being sold at artificially low prices that could undercut domestic producers. However, the agreement's structure and enforcement have been subjects of ongoing debate, with critics arguing that the price floors may not adequately protect U.S. growers while supporters contend they ensure fair market access. Understanding how these regulatory mechanisms work is essential to grasping the potential consequences of the agreement's termination.

A Decades-Long Trade Dispute

The U.S.–Mexico tomato trade dispute has roots stretching back decades, with various agreements and renegotiations shaping the relationship between the two countries' agricultural sectors. Over the years, multiple versions of suspension agreements have been negotiated, each attempting to address the evolving dynamics of cross-border tomato trade. These agreements have served as key milestones in the broader U.S.–Mexico trade relationship, reflecting the ongoing tension between protecting domestic agriculture and maintaining affordable food supplies for consumers.

What is the U.S.-Mexican Tomato Suspension Agreement?

Tomatoes on a world map symbolizing trade routes between the U.S., Mexico, and Canada.

The U.S.-Mexican Tomato Suspension Agreement is a trade agreement that sets a minimum price for fresh tomatoes imported from Mexico into the United States. The original agreement was established in 1996 to prevent Mexican tomato growers from selling tomatoes at unfairly low prices (a practice known as "dumping") in the U.S. market. This was designed to protect domestic tomato producers, particularly in Florida, who claimed that low-priced Mexican imports were harming their businesses.

The agreement has been updated and modified several times since its inception, with the most recent version implemented in 2013. These revisions often involve adjustments to the minimum price and the scope of the agreement. For example, the 2013 agreement introduced different minimum prices for various categories of tomatoes, including:

  • Field tomatoes
  • Greenhouse tomatoes
  • Cherry and grape tomatoes

Post-Termination Tariff Impact

On July 14, 2025, the U.S. government imposed a 17.09 percent tariff on fresh tomatoes imported from Mexico and terminated the nearly three-decade-long Tomato Suspension Agreement, signaling a major shift in tomato trade policy. This action has raised significant concerns about the effects on both U.S. producers and consumer prices. Industry leaders, including Dante Galeazzi, president and CEO of the Texas International Produce Association, have been discussing the implications of these changes and the early stages of USMCA renegotiations. The termination marks a departure from the framework that had governed tomato trade for nearly 30 years.

Debate Over Agreement Effectiveness

The Tomato Suspension Agreement has faced criticism from multiple sides throughout its existence. Some U.S. growers have argued that the agreement failed to adequately protect their interests, while others have contended that it provided necessary stability for cross-border trade. The termination of the agreement reflects these ongoing tensions and the difficulty of finding a framework that satisfies all stakeholders in the complex tomato supply chain.

TSA's Role in Market Shaping

The Tomato Suspension Agreement (TSA) between the U.S. and Mexico, first established in 1996, was designed to regulate the importation of Mexican tomatoes into the United States. For nearly three decades, this agreement served as the primary framework governing the flow of fresh tomatoes across the border. The agreement's design and implementation have been central to understanding how trade policies can shape agricultural markets and influence the availability and pricing of produce for American consumers.

Canada, while not a direct party to the U.S.-Mexican agreement, is significantly impacted because the U.S. minimum price policy distorts prices across the entire North American region. Understanding these dynamics requires looking at the interplay between all three countries.

The Bigger Picture: Trade, Consumers, and Your Plate

The U.S.-Mexican Tomato Suspension Agreement highlights the complexities of international trade and its direct impact on consumers. While these agreements are intended to address specific issues like unfair pricing, they create ripple effects that influence the entire market. As consumers, understanding these dynamics empowers us to make informed choices about the food we buy and to engage in discussions about trade policies that shape our world.

Three Decades of Dispute

The Florida Tomato Exchange's request to terminate the 2019 Tomato Suspension Agreement represents the latest development in a dispute that has lasted for almost three decades. This ongoing conflict encapsulates the sometimes-rocky trade relationship between the United States and Mexico, particularly in the agricultural sector. The termination of the agreement marks a significant turning point in this long-standing dispute, with implications that extend beyond just the tomato industry to broader U.S.–Mexico trade relations.

Industry Calls for New Agreement

The Border Trade Alliance has noted that more than 400 businesses have written to the Department of Commerce urging maintenance of the Tomato Suspension Agreement, citing concerns about jobs and economic stability. NatureSweet, the leading branded tomato company in North America, has called for immediate negotiation of a new trade agreement to protect affordability, food safety, and the future of fresh tomatoes in America. The termination of the agreement has created uncertainty across the supply chain, with stakeholders from across the industry advocating for a swift resolution to avoid disruptions to food availability and security.

Economic Stakes of Termination

A coalition of organizations has written to the U.S. Department of Commerce expressing concern that the decision to withdraw from the 2019 Agreement could create challenges for the U.S. economy. The coalition has urged the Department to pause the decision to allow time to negotiate a new agreement. This broad-based opposition from multiple industry groups underscores the significant economic stakes involved in the tomato trade and the potential cascading effects of disrupting established trade relationships.

Supply Chain Disruption Fears

The U.S.–Mexico tomato trade, long governed by the Tomato Suspension Agreement, has been thrown into disarray since the Trump administration terminated the pact in April 2025 and imposed a 17% tariff on Mexican imports. This move, framed as a defense of domestic growers, has triggered what has been described as a seismic shift in agricultural trade dynamics with far-reaching implications for agribusiness. The tomato suspension agreement has drawn both critics and supporters over the years, with the terms of U.S. tomato trade with Mexico again hanging in the balance in recent years. The termination raises significant concerns about the availability of fresh tomatoes and the potential impact on food security across the United States.

How the tomato study compares with related market research

A related market-price analysis reported that the 2013 agreement raised Mexican tomato prices by 5.5% and U.S. prices by 1.3%; it also broke out larger Mexican increases in summer than winter.[1]

That analysis compared average weekly U.S. tomato prices before and during the agreement, reporting $0.43 per pound for 1998–2013 and $0.49 for 2013–2016.[1]

A later paper on sugar agreements cited Kosse and Devadoss’s tomato study as a similar case involving price floors and restrictions on U.S. imports of Mexican tomatoes.[2]

Everything You Need To Know

1

What is the U.S.-Mexican Tomato Suspension Agreement and why was it created?

The U.S.-Mexican Tomato Suspension Agreement is a trade agreement setting a minimum price for fresh tomatoes imported from Mexico into the United States. It was initially established in 1996 to address concerns from U.S. growers, particularly those in Florida, who alleged that Mexican tomato producers were engaging in 'dumping'—selling tomatoes at prices below production costs. The goal was to protect these domestic producers from unfair competition, ensuring they could compete in the market. This agreement has been updated multiple times, including the most recent in 2013, which adjusted the minimum prices and specified different categories of tomatoes like field, greenhouse, cherry, and grape tomatoes.

2

How does the Tomato Suspension Agreement affect the price of tomatoes for consumers?

The Tomato Suspension Agreement directly impacts the price consumers pay for tomatoes. By setting a minimum price for Mexican tomatoes, the agreement reduces the likelihood of very low prices that might result from dumping practices. This can lead to higher prices for tomatoes compared to what might exist in a completely free market scenario. While the agreement aims to protect U.S. growers, the result can be less affordable tomatoes for consumers. The dynamics become even more complex considering regional variations within the U.S. and the influence of the agreement on Canadian markets due to the integrated North American trade environment.

3

Why does Canada get mentioned in the context of the U.S.-Mexican Tomato Suspension Agreement?

Canada is significantly affected by the U.S.-Mexican Tomato Suspension Agreement because the minimum price policy in the U.S. distorts prices across the entire North American region. As part of a closely connected trade environment, the pricing and availability of tomatoes in one country influence the others. For example, if Mexican tomatoes are more expensive in the U.S. due to the agreement, Canadian consumers might see their prices shift as well. The interconnectedness of the three countries' markets means that trade policies in one can create ripple effects throughout the others. This highlights how international trade agreements can extend beyond the direct parties involved.

4

What are the specific types of tomatoes considered under the 2013 version of the Tomato Suspension Agreement?

The 2013 version of the U.S.-Mexican Tomato Suspension Agreement introduced specific categories of tomatoes to account for variations in production and market dynamics. The categories include field tomatoes, greenhouse tomatoes, and cherry and grape tomatoes. By differentiating among these types, the agreement aims to apply more nuanced minimum price standards that better reflect the cost of production and market conditions specific to each type. This approach allows for a more tailored approach to regulating the trade of Mexican tomatoes into the U.S.

5

How do trade agreements, like the U.S.-Mexican Tomato Suspension Agreement, demonstrate the complexities of international trade?

The U.S.-Mexican Tomato Suspension Agreement exemplifies the complexities of international trade in several ways. Firstly, it shows how trade policies, designed to protect domestic producers from unfair practices, can lead to consequences such as increased consumer prices and altered market dynamics. Secondly, the agreement highlights the interconnectedness of markets, demonstrating how policies in one country, the U.S., can significantly impact others, like Mexico and Canada. Thirdly, it illustrates the ongoing debates and revisions that characterize trade agreements, as seen in the multiple updates to the suspension agreement since 1996. These complexities require a nuanced understanding of economics, politics, and the interplay between producers, consumers, and governments.
