Magnesium chloride is highly soluble, but it also has a strong tendency to absorb moisture from the surrounding environment.
For this reason, storage conditions matter more than some buyers expect.
During long-distance transportation or storage in humid areas, poor packaging can lead to moisture absorption, caking and handling problems.
This is especially important for bulk buyers who may keep several tons of material in their warehouse before production.
Keeping magnesium chloride in sealed packaging and a dry storage area can help maintain its original condition.
For large orders, packaging should therefore be discussed together with the product specification, not treated as an afterthought.
