China hexahydrate magnesium chloride and anhydrous magnesium chloride

China is a major global producer and exporter of magnesium chloride, which is mainly divided into two core categories: hexahydrate magnesium chloride and anhydrous magnesium chloride, with a wide range of specifications to meet diverse demands. The country leads the global market for the following reasons:

1. Abundant Raw Material Resources

China boasts world-class salt lakes such as the Qarhan Salt Lake in Qinghai. Vast reserves of salt lake brine, underground brine and seawater provide sustainable raw materials for large-scale production. On average, every kilogram of seawater contains 3.2 grams of magnesium chloride. The main mineral forms are carnallite and bischofite.

Magnesium chloride resources are geographically concentrated. The Qarhan Salt Lake in Golmud holds 1.65 billion tons of magnesium chloride reserves, ranking among the world’s premier potassium-magnesium salt deposits. In terms of output:

· Shandong Province accounts for about 46.7% of national production, with an annual output of over 2 million tons.

· Qinghai Province takes up around 19%, with an annual output of 1 million tons.

· Xizang Province contributes approximately 17%, with an annual output of 700,000 tons.

The three regions together make up over 82% of China’s total output. The national annual production capacity exceeds 4 million tons. Output surpassed 6 million tons in 2020 and keeps growing steadily.

2. Large Production Capacity & Outstanding Cost Advantages

Supported by abundant salt lake and seawater resources, China has formed a complete industrial chain. Large-scale and automated production greatly improves efficiency. Lower costs for labor, energy and raw materials grant Chinese products strong price competitiveness compared with those from Europe and America.

3. Complete Product Specifications for Global Markets

We consistently supply a full range of products, including 46% hexahydrate magnesium chloride (flake, powder, pellet), 99% anhydrous magnesium chloride and food-grade magnesium chloride. These products serve multiple industries worldwide, such as mineral processing, de-icing, building materials, smelting, food processing, feed additives, general industry, agricultural magnesium fertilizer, mechanical processing, electronics and petroleum.

4. Reliable Quality & Mature Export Standards

Years of technological upgrading ensure stable purity, good water solubility and qualified moisture absorption of industrial-grade magnesium chloride. Food-grade products pass international tests and comply with import standards of Europe, America, Southeast Asia, the Middle East and other regions. Strict impurity control is implemented across all product lines.

5. Comprehensive Packaging, Logistics & Customs Services

We offer diversified packaging options: 25kg bags, bulk bags and bulk shipment for sea transportation. With well-equipped ports and streamlined export procedures, we guarantee short lead times and stable large-volume delivery.

6. High Compatibility with Global Market Demands

Magnesium chloride is widely used worldwide for road dust suppression, mine dust control and winter road de-icing. China’s 46% hexahydrate magnesium chloride features excellent cost performance, making it the top choice for global engineering contractors and traders.

Characteristics of chinese hexahydrate magnesium chloride and anhydrous magnesium chloride

1. Diverse Product Grades & Production Technologies

· Anhydrous magnesium chloride: Produced via salt lake dehydration (carnallite pyrolysis), titanium by-product process (purity above 99%) and multi-stage brine dehydration (eco-friendly and energy-saving technology).

· Hexahydrate magnesium chloride flake: Includes acid-processed white flakes (high purity and high transparency), traditional simmered regular flakes (cost-effective) and natural salt lake crystalline flakes (high purity).

Products are classified into industrial grade, food grade and feed grade, as well as white flakes, regular flakes and refined flakes to fit various application scenarios.

2. Concentrated Manufacturers & Competitive Pricing

Magnesium chloride manufacturers are densely distributed in China. Intense market competition helps keep prices favorable. For products of equivalent quality, Chinese suppliers offer more competitive quotations than overseas counterparts.

3. Consistent & Trustworthy Quality

Taking Yuze Chemical as an example, we have specialized in magnesium chloride production for 13 years since 2013. We continuously upgrade production equipment and techniques, and some products have obtained EU certification. Every batch of anhydrous and hexahydrate magnesium chloride undergoes in-plant random sampling and third-party inspection before delivery.

4. High Operational Efficiency

Most domestic manufacturers achieve high efficiency in production, packaging and transportation (land and sea). At Yuze Chemical, the daily output reaches 500–700 tons for regular hexahydrate magnesium chloride flakes and around 300 tons for high-purity variants. Our factories are within 4 to 8 hours’ transportation distance from major ports including Qingdao, Weifang and Rizhao.

Summary

Benefiting from dual raw material sources of salt lakes and seawater, diversified production technologies and a full product portfolio, China stands as the world’s largest producer and exporter of magnesium chloride.

Anhydrous magnesium chloride is renowned for high purity, low impurities and eco-friendly production, ideal for high-end metallurgy and fine chemical industries. Hexahydrate magnesium chloride flakes boast high cost performance and complete grading systems, dominating the building material and de-icing markets. Chinese magnesium chloride products maintain strong overall competitiveness globally.
