Brazilian Compact Magnesite
Dense, compact natural magnesite from Bahia, Brazil, prized for its high bulk density and low porosity in refractory applications. It is a natural magnesium carbonate in the crude or crushed state, not subjected to calcination or other processing beyond physical treatment, so it falls under tariff item 2519.10.00.
Chemical Grade Magnesite Powder
Micronized natural magnesite ground to 10-50 micron particles for fertilizer and chemical uses, retaining its full MgCO3 composition. Grinding is a permitted physical process under Chapter 25 notes, and the product remains natural magnesium carbonate, not chemically altered.
Chinese Magnesite Concentrate
Flotation concentrate from Liaoning, China, with about 94% MgCO3 and controlled silica, produced by froth flotation. This physical concentration process is allowed under Chapter 25 notes, and the product remains natural magnesium carbonate, so it fits tariff item 2519.10.00.
Dead-Burn Refractory Magnesite
Dead-burn refractory magnesite in large particles (2-6mm) is a natural magnesium carbonate mineral used as a soil amendment to supply magnesium and neutralize acidity. It falls under tariff item 2519.10.00 because it is in its crude state, having only been crushed and screened without any further processing such as calcination or sintering.
Floatation Grade Magnesite
Beneficiated magnesite concentrate from froth flotation, achieving over 95% MgCO3 purity while remaining chemically unchanged. Froth flotation is a mechanical/physical process allowed by Chapter 25 notes, so this natural magnesium carbonate falls under tariff item 2519.10.00.
Greek Magnesite Ore
Premium cryptocrystalline magnesite from Kozani, Greece, with about 97% MgCO3 purity and low impurities, in its natural state. This is a natural magnesium carbonate not subjected to any processing beyond physical treatment, so it is classified under tariff item 2519.10.00.
