Fertilizer Industry Facing Legal Challenges

Recently, several antitrust class action lawsuits were filed against the world’s largest fertilizer producers, alleging a coordinated effort to artificially inflate the prices of essential crop nutrients.  The primary lawsuits, Union Line Farms, Inc. v. The Mosaic Company, et al., filed in Colorado, target a group of large fertilizer producers. The defendants include:

• The Mosaic Company
• Nutrien Ltd.
• CF Industries Holdings, Inc.
• Koch Agronomic Services, LLC
• Yara International ASA
• Canpotex LTD

The complaints allege that starting around January 2021, these companies exploited their dominant market positions to restrict supply and maintain "capacity discipline." While the companies historically attributed price spikes to global supply chain disruptions and geopolitical volatility, the lawsuits argue that prices remained at record highs long after those external pressures subsided.

The litigation highlights the difference from historical pricing norms. Between 2021 and 2022, the cost of nitrogen, phosphorus, and potassium (NPK) fertilizers surged significantly.  According to the filings, this alleged price fixing added an estimated $128,000 in additional input costs per farm in 2022 alone. While farm expenses reached these record levels, the defendant companies reported some of the highest profits in their corporate histories.

The private class action suits are not the only pressure these companies face. In early March 2026, media reports surfaced that the U.S. Department of Justice (DOJ) Antitrust Division has opened its own investigation into whether these producers colluded to raise prices. This federal scrutiny follows months of pressure from agricultural groups and lawmakers concerned about market concentration in the fertilizer sector.

It is important to note that these allegations have not been proven in court and the defendants deny wrongdoing.

The Class Action Lawsuit

These cases are currently in the early stages of litigation. The courts must first decide whether to certify these as class actions.   A class action allows one or several individuals (the "Lead Plaintiffs") to sue on behalf of a larger group of people (the "Class") who have all suffered the same harm. Instead of 10,000 farmers each filing 10,000 separate lawsuits against Nutrien or Mosaic, the court consolidates them into one case.  Before the case can move forward as a class action, a judge must "certify" the class. The judge must be convinced that the group is so large that individual suits are impractical and that the legal issues are common to everyone in the group.

In class actions, attorneys almost always work on a contingency fee basis.  Farmers do not pay hourly rates or retainers. The law firms "front" all the costs of the litigation (which can run into millions for expert witnesses and data analysis).  If the case is won or settled, the court creates a "Common Fund." The attorneys then ask the judge to award them a percentage of that fund (typically 25% to 33%) to cover their fees and expenses.  The judge must approve the attorney's fees to ensure they are reasonable and that the class members (the farmers) are getting a fair share.

For producers, there is generally little risk in remaining part of the class. If the case is successful, class members receive a share of any settlement or judgment. If not, they owe nothing.  The attorneys for the lead plaintiff will typically reach out to other farmers and inform them of the lawsuit and their right within the class.  Farmers should retain fertilizer purchase records and related documentation to substantiate any potential claim if the litigation results in a recovery.
