Cosaco

What Cosaco does

Cosaco is a global manufacturer of essential copper salts, headquartered in Hamburg, Germany with a second production facility in Houston, Texas. Formed in early 2022 through the unification of Spiess-Urania Chemicals GmbH (tracing back to 1815) and Kocide LLC (dating to the early 1960s), the company produces copper hydroxide, copper oxychloride, basic copper carbonate, and cuprous oxide, all derived from 100 percent recycled copper. It is a wholly owned subsidiary of the Japanese conglomerate Mitsui & Co., Ltd. and employs more than 170 people across production, sales, registration, development, and research.

The company serves agricultural and industrial end markets through two complementary portfolios. Its agricultural offering includes globally recognized brands such as KOCIDE, FUNGURAN, COBOX, and CUPROZIN for crop protection (fungal and bacterial disease control in fruit, nut, and vegetable crops), plus QUESTURAN PRO and PLONURAN DUO trace nutrient fertilizers and basic copper carbonate as an animal feed additive. Its industrial offering covers basic copper carbonate for wood preservation, cuprous oxide for marine antifouling coatings, and high-purity copper salts for specialized uses including catalysts, microelectronics, glass and ceramic coloring, and electroplating. Proprietary production methods yield distinctive acicular particle structures in its copper hydroxide products, and the Hamburg site operates a closed-loop water system with zero wastewater discharge.

Cosaco operates a B2B direct sales model across more than 60 countries, with revenues generated by one-time sales of formulated products and industrial raw materials. It holds a dense regulatory and certification stack spanning ISO 9001, 45001, and 50001, EU Biocides approval, EU feed additive clearance, AAFCO listing, and four organic certifications (EU Organic, ECOCERT, JAS, OMRI), and has achieved EcoVadis Gold status in 2024 and 2025 (96th percentile). Geographic growth is anchored by its two production hubs in Europe and North America, with the Houston plant currently mid-way through a 2020-launched five-year modernization program intended to expand capacity and introduce smart production capabilities.

Direct peers

• Nufarm: Australia-headquartered crop protection company with a meaningful copper-based fungicide portfolio sold globally. Directly competes with Cosaco's KOCIDE/FUNGURAN/COBOX/CUPROZIN product lines for crop protection shelf space and grower relationships.
• ADAMA: Israel/China-based global crop protection company offering copper fungicides alongside a broad portfolio of herbicides, insecticides, and fungicides. Directly competes with Cosaco in formulated crop protection products across multiple geographies.

Broad incumbents

• UPL: Indian-headquartered global agrichemical major with broad crop protection and seed treatment offerings. Competes with Cosaco across multiple crop protection categories and geographies, though copper salts are a smaller share of UPL's portfolio.
• BASF: German global chemical major with an Agricultural Solutions division covering fungicides, including copper-based options. Competes with Cosaco in crop protection while also supplying broader industrial chemical markets relevant to Cosaco's industrial product line.
• Bayer Crop Science: Global agrichemical and seed leader with a substantial fungicide portfolio. While not focused on copper salts, it competes with Cosaco's crop protection products through alternative fungicide chemistries and is a key benchmark for global ag-input distribution.
• Corteva: US-headquartered agrichemical and seed company with a broad crop protection portfolio. Competes with Cosaco for grower spend through alternative fungicide chemistries and integrated pest management programs.
• FMC Corporation: US-based agrichemical company with a global crop protection portfolio in insecticides, herbicides, and fungicides. Competes with Cosaco for crop protection shelf space across multiple regions though not focused specifically on copper salts.

Regional players

• Sumitomo Chemical: Japanese chemical company with crop protection and specialty chemical operations, and historically linked to the same Mitsui-Zaibatsu group as Cosaco's parent Mitsui & Co. Overlaps with Cosaco in crop protection and basic inorganic chemicals across Asia-Pacific markets.

Emerging players

• Nordox: Norway-based specialist producer of cuprous oxide for antifouling and agricultural applications. A direct niche peer to Cosaco in cuprous oxide antifouling markets, though significantly smaller in scale and geographic reach.
• Industrias Químicas del Vallés (IQV): Spain-based specialty manufacturer of copper-based crop protection products and other metal-based fungicides. A direct competitor to Cosaco in formulated copper fungicides across Mediterranean and Southern European markets, with smaller global reach.
