Floatation Grade Magnesite
Beneficiated magnesite concentrate from froth flotation process, achieving 95%+ MgCO3 purity while remaining chemically unchanged natural carbonate. HTS 2519.10.00.00 applies as physical separation doesn't alter mineral composition.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If converted to magnesium carbonate powder via precipitation
Chemically precipitated MgCO3 (not natural) falls under carbonates of chapter 28.
If dead-burned for refractories
Sintering at 1600°C+ converts carbonate to oxide, changing heading within same statistical suffix.
