Raw Magnesite Ore
Natural magnesium carbonate ore extracted from magnesite deposits, typically containing 85-95% MgCO3 with impurities like silica and iron oxides. It falls under HTS 2519.10.00.00 as unprocessed natural magnesite used primarily as feedstock for refractory and chemical production.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If calcined to quicklime
Thermal decomposition converts natural magnesite to magnesium oxide, classified under fused or dead-burned magnesia.
If heavily mixed with other earth minerals
Magnesite with significant impurities falls under mineral substances not elsewhere specified in Chapter 25.
If chemically processed into synthetic preparations
Post-extraction chemical treatment moves it from natural ores to prepared chemical products.

Import Tips & Compliance
• Verify magnesite purity through lab analysis certificates to confirm classification as natural magnesium carbonate over 50% MgCO3
• Include geological origin documentation; ores from certain countries may face antidumping duties
• Avoid misclassification as dead-burned magnesia (2619.90) by ensuring no thermal processing
