Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If purified to USP/pharma grade
High-purity processed magnesium sulfate becomes a chemical intermediate.
If containing significant natural salts
Mixed natural sodium salts classify under heading 2511, not pure MgSO4.
If chemically treated for specific uses
Prepared chemical products of unspecified composition fall under 3824.

Import Tips & Compliance
• Include geological survey reports proving evaporite origin
• Maintain coarse crystal form; grinding risks 2530.90.8010 classification
• Declare exact magnesium sulfate content to avoid Chapter 28 chemical headings
