About Sac Ag

Sacramento Ag Products, LLC (Sac Ag) is a strategic joint venture between two industry-leading chemical manufacturers—Thatcher Company of California and Hydrite of Wisconsin. With decades of experience in chemical production, distribution, and agronomic services, Thatcher and Hydrite's mission is to deliver high-performance agricultural and specialty chemical solutions to manufacturers, retailers, and distributors across the West Coast. This collaboration brings advanced formulations, reliable supply chains, and support to meet the evolving needs of California’s agriculture industry.

Our expanding product line is tailored to serve the entire West Coast region, offering not only innovative chemical solutions that are new to this area but also the dedicated customer service and technical support necessary to help your business succeed. We understand that reliability and responsiveness are just as important as product performance, and that’s why Sac Ag is committed to delivering both.

Agricultural Products

At the heart of our product portfolio are thiosulfate-based solutions for the agricultural industry and bisulfite-based products for a wide range of industrial applications. Sac Ag proudly manufactures both ammonium thiosulfate and potassium thiosulfate, providing manufacturers, retailers, and distributors throughout California’s Central Valley—and beyond—with high-quality, locally produced fertilizers that meet the evolving demands of modern agriculture.

Industrial Products

In addition, Sac Ag leads the way in producing purpose-made sodium bisulfite, ammonium bisulfite, magnesium bisulfite, and sodium thiosulfate for industrial applications—marking a first for chemical manufacturing in the state of California. These bisulfite products are formulated to support critical processes in sectors such as water treatment, mining, and paper manufacturing.

Beyond agricultural and industrial uses, our chemical solutions also serve vital roles in both the water treatment and precious ores industries. With a firm commitment to local sourcing, regional production, and on-site storage, Sac Ag ensures fast delivery, consistent supply, and dependable service for customers throughout the West Coast.
