Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pebbled or graded for macadam
Chapter note prioritizes heading 2517 for processed pebbles, gravels, and similar shaped materials.
If iron content exceeds principal constituent
High iron magnesite classified by iron oxide content under iron ores rather than magnesium carbonate.

Import Tips & Compliance
• Provide crushing specifications and MgCO3 content assays; lumps over specific sizes may require different handling declarations
• Check for radioactive impurities common in some magnesite deposits requiring additional safety certifications
• Use proper NAICS codes (212319) for statistical reporting to avoid CBP queries
Related Products under HTS 2519.10.00.00
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.
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.
Metallurgical Grade Magnesite
Medium-purity natural magnesite (90% MgCO3) specifically sized for dead-burning into refractory bricks used in steel furnaces. Remains under HTS 2519.10.00.00 as the uncalcined natural carbonate mineral.
Chemical Grade Magnesite Powder
Micronized natural magnesite ground to 10-50 micron particle size for fertilizer and chemical applications, retaining full MgCO3 composition. HTS 2519.10.00.00 covers this physically processed but chemically unchanged mineral.
Dead-Burn Refractory Magnesite
Large-particle natural magnesite (2-6mm) used directly as soil amendment in agriculture to supply magnesium and neutralize acidity. Classified HTS 2519.10.00.00 as unprocessed magnesium carbonate mineral.
Greek Magnesite Ore
