BREAKING NEWS TODAY: New 25% tariffs will hit both sides of the US-Canada border, making your Canadian embryos a quarter more expensive. Act now.

EXECUTIVE SUMMARY: Implementing 25% tariffs on virtually all US-Canada trade effective today (March 4, 2025) creates unprecedented disruption in North America’s integrated cattle and embryo markets, threatening $1.14 billion in annual US dairy exports to Canada. These tariffs are pivotal for the dairy genetics and breeding sector, with immediate impacts on the cross-border movement of live cattle and genetic material. The International Dairy Foods Association warns that “a prolonged tariff war will deliver significant economic damage to American dairy farmers, processors, and rural communities.” Dairy producers must immediately recalculate breeding economics, particularly for pre-purchased but unshipped genetics that will face tariffs regardless of purchase date, while exploring domestic alternatives to maintain profitability in this new trade landscape.

KEY TAKEAWAYS

• All pre-purchased but unshipped genetics will be subject to 25% tariffs when crossing the border, regardless of when the purchase was made.
• The integrated North American cattle supply chain faces significant disruption as tariffs affect both countries simultaneously.
• Canada has implemented immediate retaliatory tariffs on US goods worth CA$30 billion (US$20.7 billion), including dairy products such as yogurt and buttermilk.
• This escalation in trade tensions threatens US dairy exports to Canada ($1.14 billion) and Mexico ($2.47 billion).
• Dairy producers should evaluate whether imported genetics justify the 25% premium over domestic alternatives while exploring value-added processing to offset tariff costs.

The escalating trade tensions between the United States and Canada have resulted in significant tariff impositions threatening to upend the deeply integrated North American cattle and embryo trade. As of March 4, 2025, these tariffs represent a profound shift in cross-border agricultural commerce largely unimpeded since the 1988 Reagan-era free trade pact. These developments introduce unprecedented challenges and potential market reconfiguration for dairy producers involved in genetics trade, breeding stock acquisition, or those leveraging the growing beef-on-dairy market. This article examines the multifaceted impact of these tariffs on the cattle and embryo trade between these two historically cooperative trading partners.

Breaking Down the 25% Tariff: Immediate Impacts on Dairy Genetic Flow

President Trump’s administration has implemented a sweeping 25% tariff on virtually all Canadian imports, with energy resources facing a reduced 10% tariff. This blanket application makes no explicit exemption for live cattle or bovine embryos, subjecting these biological assets to the entire 25% markup. Simultaneously, Canada has announced retaliatory measures, imposing their own 25% counter-tariffs on CA$30 billion (US$20.7 billion) worth of American products, with implementation coinciding with the U.S. tariff date.

The implications for dairy genetics and cattle trade cannot be overstated. These tariffs are pivotal when genomic technology has accelerated genetic progress to unprecedented levels. Producers are making increasingly strategic breeding decisions based on genomic data, but significant tariff burdens complicate these decisions.

The tariffs come at a particularly sensitive time for the US dairy industry, which has built substantial export relationships with Canada over the past decade, as demonstrated in the table below:

This table illustrates the significant economic stakes in the tariff dispute. Any disruption to these trade relationships has profound implications for both countries’ dairy sectors, particularly as the US dairy industry supports more than 3.2 million jobs and contributes almost $800 billion to the US economy.

The specific impact on genetic trade between the US and Canada is substantial, as shown in the cross-border bovine genetic trade data:

Sources: Observatory of Economic Complexity (OEC), 2023; Statistics Canada, 2023

This table demonstrates the significant bilateral trade in genetic material. Canada is the primary source of bovine semen for the United States, accounting for approximately 82% of US bovine semen imports. The 25% tariff would add roughly $8.1 million in costs to US importers of Canadian genetics based on 2023 trade levels.

The growing importance of Canadian dairy genetics to US breeding programs is evident in the steady increase in Canadian dairy cattle exports to the United States over recent years:

This data reveals a dramatic 121% increase in the value of Canadian dairy cattle exports to the United States since 2019, reaching nearly million in 2023. The newly implemented 25% tariff will add approximately $7.4 million in additional costs to US dairy producers importing Canadian genetics, based on 2023 trade levels. This substantial growth trajectory demonstrates how integrated the two countries’ dairy genetics programs have become—and how disruptive these new tariffs will be.

Critical Timing: What Happens to Pre-Purchased Embryos Caught in Tariff Transition

The embryo market faces particular challenges under the new tariff regime. While conventionally bred calves can be produced domestically, elite embryos often cross borders to maximize genetic potential. The 25% tariff represents a significant premium that must be justified through superior genetic merit.

The timing of tariff implementation becomes critically essential—purchases made before March 4, 2025, but not yet shipped across the border will face these new tariffs. This creates immediate urgency for genetic materials caught in this transitional period.

Value-added processing of genetic materials presents potential tariff mitigation opportunities. For example, the domestic gender-selected semen market has grown substantially in recent years. Producers may achieve returns that offset tariff costs by focusing on these higher-value genetic products rather than raw materials.

International Dairy Foods Association Responds to Tariff Implementation

The International Dairy Foods Association (IDFA) has responded to the new tariffs with concern, releasing a statement urging a quick resolution: “The U.S. dairy industry urges the Trump Administration to quickly resolve the ongoing tariff concerns with Canada, Mexico, and China—America’ top agricultural trading partners. A prolonged tariff war will deliver significant economic damage to American dairy farmers, processors, and rural communities. Therefore, we urge the Administration to resolve these tariffs as soon as possible.”

This urgent call for resolution comes as the dairy industry has invested more than $8 billion in new processing capacity that will come online in the next few years. With approximately 18% of US milk production destined for export markets, the industry depends on increased trade access to open new markets and increase exports. The IDFA notes that after being a net importer of dairy products a decade ago, the United States now exports $8 billion to 145 countries, with Mexico and Canada representing more than 40% of these exports.

Canada’s Retaliatory Measures Target US Dairy

Canada’s response to the US tariffs has been swift and proportional. Prime Minister Justin Trudeau announced that CA$30 billion (US$20.7 billion) worth of goods from the US into Canada will be subject to a 25% levy. Importantly for the dairy sector, this includes a wide range of dairy products, from yogurt to buttermilk and other fresh and processed foods.

This direct targeting of dairy products in Canada’s retaliatory measures creates a double impact on the North American dairy industry. Imports and exports face new tariff barriers simultaneously. For operations with integrated cross-border production systems, this dual impact could create significant challenges for maintaining cost-effective production.

Conclusion: Navigating Uncharted Waters in North American Dairy Genetics

The 25% tariffs implemented between the United States and Canada on March 4, 2025, represent a seismic shift in the dairy genetics landscape, which has thrived on cross-border collaboration for decades. The timing couldn’t be more challenging—they arrive precisely as genomic advancements accelerate genetic progress. For an industry historically defining itself through innovation and adaptation, this represents perhaps its most significant test in a generation.

Forward-thinking dairy producers must now move quickly to reevaluate their genetic procurement strategies. Calculations that made economic sense just days ago now require complete reconsideration. Elite Canadian genetics must demonstrate 25% more value to justify their new cost structure, while domestic alternatives suddenly present previously overlooked competitive advantages. The producers who will thrive view this disruption not merely as an obstacle but as a catalyst for strategic evolution in their breeding programs.

The resilience of the North American dairy and beef sectors will be tested as production systems that evolved under decades of free trade adjust to this new reality. Adaptation will require leveraging the full power of genomic technology to make increasingly precise breeding decisions, maximizing the value derived from each pregnancy, and exploring creative arrangements to maintain genetic progress despite trade barriers. While political solutions may eventually emerge, waiting for such developments represents a dangerous gamble.

Ultimately, these tariffs will separate forward-looking producers from those stuck in established patterns. The most successful operations will be those that rapidly pivot to new sourcing strategies, leverage domestic genetic resources more effectively, and implement data-driven approaches that maximize reproductive efficiency in the face of increased costs. The North American dairy industry has repeatedly demonstrated its capacity for innovation throughout its history, and despite these unprecedented challenges, there’s every reason to believe it will do so again.
