Rongqing Chemical in CAC Show 2024(Shanghai): Focusing on Kieserite, Connecting Global Agricultural Micronutrient Needs

March 13-15, 2024—The 24th China International Agrochemicals & Crop Protection Exhibition (CAC Show 2024), a highly anticipated event in the global agrochemical industry, grandly opened at the National Exhibition and Convention Center (Shanghai, China). As a China professional manufacturer and exporter of Kieserite and Magnesium Sulfate basic chemical raw materials sulfate salts, Rongqing Chemical showcased its flagship products—Kieserite, Magnesium Sulfate, and Customized Granular Trace Element Fertilizers—at this exhibition (Booth No.: 22C40 [Hall 1.2 Fertilizer Zone B]), demonstrating the company’s innovative capabilities and international service capacity in agricultural fertilizer solutions to global clients.

Focusing on core business: Full-chain layout of Kieserite, export experience empowering global markets

Since its establishment, Rongqing Chemical has consistently focused on the research, development, production, and export of basic chemical Raw Materials such as Magnesium Sulfate, Ferrous Sulfate, and Manganese Sulfate.

The company has over 20 years of technical expertise and market experience in the High-quality Magnesium Sulfate series (including Kieserite, Magnesium Sulfate Heptahydrate, Magnesium Sulfate Monohydrate, and Magnesium Sulfate Anhydrous). Relying on its own “China Magnesium Capital” production base and a rigorous quality control system (certified under the ISO 9001 quality management system, FAMI-QS, EU Reach registration), the company’s products feature core advantages such as high purity, high water solubility, low chlorine content, low heavy metal content, low free acid content, and no chemical organic compounds. Their applications span diverse sectors including agricultural cultivation, industrial applications (water treatment, soil improvement, environmental materials, mineral processing, leather manufacturing, papermaking, textiles, etc.), and animal feedadditives.

Our products are exported to over 70 countries and regions worldwide, including Southeast Asia, the Middle East, South America, and Europe, making us a trusted “Chinese reliable Kieserite manufacturer and Magnesium Sulfate factory” for international clients.”Kieserite /Magnesium Sulfate is an essential carrier of secondary nutrients for crop growth, playing a crucial role in enhancing crop stress resistance and improving fruit quality.“ Said the head of Rongqing Chemical’s International Trade Department.”We not only provide standardized products but also serve ‘Raw Material + Formulation-grade’ solutions for clients based on different soil characteristics and crop needs, and support OEM/ODM one-stop procurement services (from formulation design, packaging customization to logistics and warehousing support throughout the entire process), having helped over 230 overseas clients achieve localized brand establishment.”

Exhibition Debut: Two New Products Launched to Precisely Match Market Demands

At this CAC Show 2024 Agricultural Fertilizer Exhibition, Rongqing Chemical showcased its classic Magnesium Sulfate series (such as Magnesium Sulfate Monohydrate agricultural-grade and Magnesium Sulfate Heptahydrate feed-grade), Ferrous Sulfate (water treatment/agricultural conditioner), and Manganese Sulfate (micronutrient fertilizer), the company also debuted its annual strategic new products—Kieserite Granules and Medium-and-Micronutrient Fertilizer Granules—which became the focal point of the booth.

New Product Highlights

1. Kieserite Granules:
Using high-purity monohydrate magnesium sulfate as the core raw material, the product employs an upgraded disc granulation process to achieve “dual-element synergy + controlled-release enhancement.” The product contains magnesium oxide (MgO) ≥27% and available sulfur (S) ≥19%, with uniform particle size (1-4 mm) and good solubility. It can be used directly as a base fertilizer or top-dressing fertilizer to enhance crop magnesium and sulfur nutrition, or blended with nitrogen, phosphorus, and potassium compound fertilizers. This addresses the pain points of traditional powdered magnesium sulfate fertilizers, such as clumping, inconvenient application, and magnesium element loss, making it particularly suitable for large-scale farms with mechanized operations.

2. Micronutrient Granular:
Addressing the widespread deficiency of calcium, magnesium, zinc, boron, and other micronutrients in soil, this product uses a scientifically formulated blend (containing magnesium, sulfur, and multiple micronutrients) in a small granular form to achieve precise nutrient supplementation. The product also improves soil structure and enhances crop stress resistance (such as drought and disease resistance), making it widely applicable to cash crops (such as oil palm, tobacco, citrus, grapes, tea, and cotton) and high-value-added cultivation areas, helping farmers improve product quality and increase profit margins.

“The development of these two new products stems from our in-depth research into global customer needs,” said the technical director of Rongqing Chemical. “The international market is seeing rapid growth in demand for ‘high-efficiency, convenient, and multi-functional’ fertilizers. Granular formulations not only reduce transportation costs but also allow for blending to suit different fertilization scenarios. We aim to provide overseas customers with a ‘Chinese solution’ that better aligns with local planting practices through these new products.” 

Invitation to Collaborate: Seeking Global Partners for Development

At the exhibition site, Rongqing Chemical’s booth featured a blue-green color scheme, using product displays, application case videos, and technical manual distribution to convey product advantages to visiting clients. Purchasers from Southeast Asia, the Middle East, and Africa lingered to discuss business, showing strong interest in the “ready-to-use” nature of the magnesium sulfate fertilizer granules and the “precision nutrition” design of the trace element fertilizer. Some clients reached preliminary cooperation agreements on-site.“The China Shanghai CAC Agrochemical Exhibition is a barometer for the global

agrochemical industry and a key platform for us to connect with international markets,” said the general manager of Rongqing Chemical at the exhibition site. “We have been deeply involved in the sulfur-magnesium fertilizer sector for years, with a stable raw material supply chain and mature production processes. We also understand how to meet the agricultural needs of different countries through customized services. This exhibition, we not only aim to showcase new products but also look forward to establishing long-term partnerships with global farmers, distributors, and agrochemical companies—whether it be standard product procurement, OEM manufacturing, or regional brand co-promotion, we will provide you with a ‘One-Stop’ solution through our professional team and flexible policies.”
