Across the Soda Ash Industry: Searles Valley Minerals Enters Chapter 11

Editor’s Note: This article is the first installment in our new Across the Soda Ash Industry series. From market trends and company developments to industry challenges and opportunities, this series aims to help members better understand the forces shaping the soda ash industry and the communities that depend on it.

The soda ash industry is often discussed in terms of local operations, but the reality is that producers across North America and around the world are connected through the same markets, customers, and economic pressures. Developments affecting one producer can provide valuable insight into challenges and trends impacting the industry as a whole.

One recent example is Searles Valley Minerals, which filed for Chapter 11 bankruptcy protection on June 15, 2026, and began a court-supervised process to sell the company while continuing operations. While this development is taking place hundreds of miles from Wyoming, it is significant because Searles is one of only a handful of natural soda ash producers in the United States.

For workers in Wyoming’s trona and soda ash industry, this news serves as a reminder that even long-established mining operations can face serious challenges when market conditions, operating costs, and unexpected events collide.

Who Is Searles Valley Minerals?

Searles Valley Minerals operates near Trona, California, where it extracts minerals from underground brine deposits beneath Searles Lake. The company produces borates, sodium sulfate, salt products, and historically produced soda ash. The operation also includes its own railroad and a water utility that serves the local community. As of the bankruptcy filing, the company employed approximately 280 people.

Searles Valley Minerals may be located in California, but its story is relevant to Wyoming workers because it operates in the same global soda ash market. While the company mines and processes minerals differently than operations in Green River, many of the challenges it faced, including pricing pressure, production costs, and changing market conditions, are issues that affect producers across the industry.

How Did They Get Here?

According to court filings, Searles Valley Minerals has faced several major challenges over the last several years.

One of the most significant events occurred in 2019 when the Ridgecrest earthquakes struck near the company’s operations. The earthquakes caused both surface and subsurface damage to the mining system. The company reports that production remains at roughly half of its pre-earthquake capacity, even years later. The financial impact of repairs and lost production totaled approximately $50 million.

At the same time, the global soda ash market became increasingly competitive. Oversupply, pressure from lower-cost producers, slowing demand in some key industries, and rising production costs all contributed to declining revenues and mounting losses. Company filings show soda ash-related sales falling significantly in recent years while annual losses continued to grow.

Earlier this year, Searles shut down its soda ash operations and implemented major workforce reductions in an effort to preserve cash and stabilize the business.

Why Should Wyoming Workers Care?

The bankruptcy of a competitor does not automatically mean better or worse conditions for Wyoming producers. Every operation has different costs, resources, and challenges.

One of the goals of this series is to help members understand developments across the broader industry. While most of us focus on our own facility and community, market conditions, production trends, and business decisions affecting producers elsewhere can have ripple effects throughout the soda ash industry. Staying informed helps us better understand the environment in which we work.

However, the filing does provide insight into the pressures facing the broader soda ash industry.

Demand for soda ash remains tied to industries such as glass manufacturing, construction, chemicals, detergents, and consumer products. When those markets slow down, producers across the world feel the impact. At the same time, global competition continues to put pressure on pricing and profitability.

For workers in Wyoming, these developments highlight the importance of maintaining safe, efficient, and competitive operations. The Green River Basin remains home to one of the world’s largest natural trona deposits, providing a strong foundation for the industry’s future. Even so, industry conditions can change quickly, and understanding what is happening across the market helps provide valuable context for discussions about production, investment, and long-term planning.

Industry Impact: Tata Steps In

One of the more notable details in the bankruptcy filing is the involvement of Tata Chemicals North America, another major Wyoming soda ash producer.

As part of the Chapter 11 process, Tata agreed to provide liquidity support and fulfill certain soda ash supply obligations that Searles could no longer meet on its own. The arrangement helps maintain customer supply while Searles works through the bankruptcy and sale process.

While this does not mean Tata is purchasing the company, it does demonstrate the importance of maintaining reliable supply chains and customer relationships within the soda ash industry.

Looking Ahead

Searles Valley Minerals is now pursuing a court-supervised sale of substantially all of its assets, including its mining operations, processing facilities, railroad, water utility, and related infrastructure. The company hopes to complete that process later this year.

The outcome will be closely watched across the soda ash industry. Whether the operation continues under new ownership, shifts its focus to other mineral products, or undergoes further restructuring, the result could influence the competitive landscape of the North American soda ash industry.

For members of USW Local 13214, the story is not simply about one company’s bankruptcy. It is a reminder that our industry operates in a global marketplace where market conditions, natural events, operating costs, and business decisions can have lasting impacts on workers and communities alike.

Understanding those challenges helps put local issues into a broader context and reinforces the importance of protecting good jobs, strong communities, and a sustainable future for our industry.

Future installments of Across the Soda Ash Industry will examine market trends, company developments, industry challenges, and other stories affecting soda ash workers in Wyoming and around the world.
