• Bunge Limited: Major agribusiness and ag-inputs company with significant Brazilian operations distributing fertilizers and crop inputs; a broad incumbent serving similar farmer customers with wider portfolio offerings.
• K+S AG: Global mineral-based fertilizer company with potash, magnesium and specialty plant nutrition products; overlaps with Calcário Diamante where magnesium and soil-fertility inputs are sold into agricultural markets.

Direct peers

• Carmeuse: Global lime and limestone producer with a significant agricultural lime line; directly comparable to Calcário Diamante's core dolomitic limestone business and serves analogous crop-soil correction use cases.
• Graymont: North-American headquartered lime producer with an agricultural lime product line serving soil pH correction; competes directly in the same product category as Calcário Diamante.
• Lhoist: International lime and mineral solutions producer serving agriculture, steel, and environmental end markets; comparable to Calcário Diamante in dolomitic limestone production and soil-corrective applications.

Emerging players

• Verde AgriTech: Brazil-listed specialty fertilizer and agricultural inputs producer focused on sustainable, multi-nutrient soil solutions; an emerging Brazilian peer pursuing similar value-added soil amendment niches like Calcário Diamante's Dianutri.

Regional players

• Galvani Fertilizantes: Brazilian phosphate and specialty fertilizer producer serving Brazilian agribusiness; overlaps with Calcário Diamante in Brazil's fertilizer and soil-correction market, though centered on phosphate nutrients rather than dolomitic lime.
