Magnesium chloride grades and forms
| Type / form | MgCl₂ content | Grade options |
|---|---|---|
| White flakes | ≥46% | Industrial and food-grade options |
| White powder | ≥46% | Industrial grade |
| Light-yellow standard grade | Confirm by model | Confirm form and application requirements |
Formula: MgCl₂·6H₂O. The percentage refers to MgCl₂ content in the hexahydrate product. The listed 46% minimum applies to the white refined products. Light-yellow standard-grade specifications are confirmed by model; food-grade availability is for white flakes.
Technical specifications
The numerical tables below apply to white refined products only. Industrial and food-grade products have different impurity limits. Light-yellow standard-grade content, physical form and impurity limits are confirmed for the selected model.

Applications
Deicing & dust control
Industrial-grade magnesium chloride for snow and ice control and dust suppression. Specify the required form, application conditions and packing arrangement.
Industrial raw materials
Applications include magnesia cement and refractory materials, along with other chemical processes. Share the process and impurity requirements for product selection.
Oilfield fluids
Industrial magnesium chloride for drilling-fluid and completion-fluid formulations. Provide the fluid composition, required concentration and impurity limits for a grade-specific review.
Food processing · food-grade flakes
Food-grade white flakes can be discussed for applications such as tofu coagulation. Specify your intended use and destination so the appropriate documents and specification can be reviewed.
How to choose magnesium chloride
1. Choose white refined or light-yellow standard grade. For white products, specify industrial flakes, industrial powder or food-grade flakes; confirm the standard-grade form and limits by model.
2. Describe the application and required impurity limits. For food-grade requests, include the intended use and destination market.
3. Confirm 25 kg or 1,000 kg packaging, label requirements, order quantity and destination.
Packaging & supply
25 kg bags
Bagged supply for the selected grade and form. Confirm the bag material, lining, printing and any custom net weight.
1,000 kg big bags
Bulk packaging can be arranged by order. Discuss pallets, loading method, destination and grade-specific packing requirements.
Sample availability, quantity and buyer-paid international courier charges are agreed before dispatch.
Storage
Store in a cool, dry, well-ventilated place. Protect from moisture and keep packaging tightly sealed when not in use.
Common questions
What does 46% mean?
It refers to MgCl₂ content in the magnesium chloride hexahydrate product (MgCl₂·6H₂O). The listed 46% minimum applies to the white products. Light-yellow standard-grade content and impurity limits are confirmed by model.
Can white powder be supplied as food grade?
The confirmed white-powder product is industrial grade. The food-grade option shown here is white flakes with a separate impurity specification.
Are flakes and powder covered by the same industrial limits?
The published industrial table covers both white flakes and white powder. State the form and any particle-size requirements so the order specification can be confirmed.
