Key Information to Confirm Before Requesting Magnesium Chloride Quotations

Recently, our editorial team at Yuze magnesium chloride factory has noticed a common issue: many new buyers and intermediaries call in for quotations by simply asking “How much is magnesium chloride per metric ton?” or “What’s the price of magnesium chloride?”

This approach is highly unprofessional. It will lead our sales team to perceive you as a novice buyer, and we cannot provide you with an accurate quotation. Worse still, it will undermine your credibility with end clients and make you appear inexperienced. Below is a detailed breakdown of why this happens:

I. Multiple Grades & Types of Magnesium Chloride

Magnesium chloride is a general term covering two core product categories: anhydrous magnesium chloride and magnesium chloride hexahydrate. Though both fall under the magnesium chloride umbrella, they differ drastically in production processes and raw material sourcing, which drives significant price gaps.

For magnesium chloride hexahydrate (commonly known as bischofite flakes), traditional production relied on natural brine. Most modern manufacturers now adopt acid-process technology, yielding higher purity with fewer impurities. Some hexahydrate variants are also by-products from potassium nitrate production, pharmaceutical intermediates and other chemical lines.

The same production differentiation applies to anhydrous magnesium chloride. Beyond manufacturing origins, the two types differ greatly in physical form, application grade, quality standards, raw materials and production workflows—all of which create wide price disparities. We have published dedicated articles covering full product classifications; you may search our website for further details.

II. Critical Details to Confirm Prior to Inquiry

As outlined above, magnesium chloride comes in diverse variants. Below are the key specifications you must clarify before requesting a quote:

2.1 Purity Content

Content is the primary factor distinguishing anhydrous and hexahydrate grades:

·   Magnesium chloride hexahydrate: MgCl₂ content ranges from 43% to 47%, with 46% as the most common standard.

·  Anhydrous magnesium chloride: MgCl₂ content ranges from 97% to 99.5%.

Purity data directly identifies which product category you require.

2.2 End Application

Magnesium chloride is a versatile basic industrial chemical used as both a core raw material and additive. Different applications mandate distinct technical specifications. For example, strict standards separate food-grade magnesium chloride from industrial-grade material.

2.3 Physical Form

·   Magnesium chloride hexahydrate: Main forms include flakes, powder and granules.

·  Anhydrous magnesium chloride: Main forms include powder, lumps and flakes.

Granular hexahydrate magnesium chloride boasts superior flowability compared to flakes, making it the preferred choice for de-icing agents. This physical difference also results in price variations.

2.4 Quality Grade

Quality is reflected in solubility, impurity levels and shelf life. For aquaculture seawater simulation applications, clear post-dissolution clarity is mandatory. Impurity content directly correlates with storage stability, purity and other performance indicators (detailed analysis is available in our previous articles, so follow our official updates for more insights).

Two widely referenced quality tiers in manufacturing are standard flakes and high-white flakes, named for their distinct quality differences.

2.5 Technical Parameters

Technical teams at end-user factories have clear parameter requirements for production processes. Some clients only specify a small set of core indicators, which allows our factory to match the exact magnesium chloride variant they need.

For instance, requirements such as MgCl₂ ≥46%, water-insoluble matter ≤0.2%, calcium ion ≤0.25% immediately identify a premium grade of magnesium chloride hexahydrate.

2.6 Packaging & Order Volume

Packaging specifications (Domestic Market)

Common packaging options: jumbo bags, 500kg bags, 50kg bags, 25kg woven plastic sacks.

Export Packaging

Standard 25kg / 50kg bags lined with PE inner film.

Order Volume

Samples / Small trial lots / Full truckloads / Full container shipments / Long-term fixed bulk orders. Order volume directly impacts unit pricing.

Summary

To simplify all the above points into one concise formula:

Purity + Physical Form + Application Grade + Quality Requirements + Special Technical Indexes + Packaging Type + Order Quantity + Target Industry

Only after confirming all these product-specific details can our magnesium chloride factory calculate an accurate quotation tailored to your order volume.
