Products classified under Tariff item 2519.90.00.90
Animal Feed Grade Magnesium Oxide
Coarse magnesium oxide powder for livestock mineral supplements, formulated to prevent grass tetany. This product is calcined natural magnesite, not a medicament, so it falls under other magnesium oxide in this tariff item.
2519.90.00Caustic Calcined Magnesite 85/15 (MgO/SiO2)
Caustic calcined magnesite blend with 85% MgO and 15% SiO2 for refractory brick production, produced by low-temperature calcination. The silica content is typical for natural magnesite and does not alter the classification as other magnesium oxide under this tariff item.
2519.90.00Caustic Calcined Magnesite Powder
Caustic calcined magnesite powder produced by moderate-temperature calcination of natural magnesite, yielding reactive magnesium oxide with residual CO2. This product is not dead-burned or fused, so it falls under other magnesium oxide in this tariff item.
2519.90.00CCM Fines Recovery Dust
Fine dust recovered from caustic calcined magnesite production, with the same chemical composition as the primary product. As a by-product of calcination, it remains magnesium oxide and is classifiable as other under this tariff item.
2519.90.00Dead-burned Magnesia 0-100mm for Rotary Kilns
Dead-burned magnesia in coarse 0-100mm granules for rotary kiln linings, produced by sintering magnesite at high temperatures to achieve low reactivity and high density. This product is not calcined beyond sintering and contains no added binders, placing it under tariff item 2519.90.00 as other magnesium oxide.
2519.90.00Dead-burned Magnesia DBM-95
Dead-burned magnesia sintered at 1700-2200°C from calcined magnesite, with 95% MgO content and high hydration resistance, used in basic refractories. The sintering process exceeds simple calcination but does not involve fusion, so it qualifies as other magnesium oxide under this tariff item.
2519.90.00Electro-fused Magnesia 98% Purity
Electro-fused magnesia produced by melting magnesite in an electric arc furnace above 2800°C, forming dense crystalline periclase with 98% purity. Fusion is a process beyond calcination or sintering, but the product remains magnesium oxide, classifiable as other under this tariff item.
2519.90.00Fused Magnesia FM-P 99.5% for EAF
Premium fused magnesia with 99.5% MgO purity, electric arc fused for EAF refractories with exceptional corrosion resistance. The fusion process creates a dense product that is still magnesium oxide, falling under other magnesium oxide in this tariff item.
2519.90.00Greek Caustic Calcined Magnesite Lumps
Lump caustic calcined magnesite from Greek deposits, partially calcined for steelmaking slag conditioning. The partial calcination produces reactive magnesium oxide, placing it under other magnesium oxide in this tariff item.
2519.90.00High Reactivity Caustic Magnesite for Animal Feed
Caustic calcined magnesite for animal feed, providing bioavailable magnesium without pharmaceutical processing. The product is calcined natural magnesite and not a medicament, so it falls under other magnesium oxide in this tariff item.
2519.90.00Large Crystal Fused Magnesia 97%
Fused magnesia with large periclase crystals over 100μm, 97% MgO purity, for ladle refractories in secondary steelmaking. The fusion process yields a stable crystalline structure, classifying it as other magnesium oxide under this tariff item.
2519.90.00Light Burnt Magnesite for Water Treatment
Light burnt magnesite for water treatment, used for pH adjustment and magnesium fortification. This caustic calcined product is reactive magnesium oxide, classifiable as other under this tariff item.
2519.90.00Reactive Caustic Magnesite 90% MgO
Reactive caustic magnesite powder with 90% MgO for fertilizer production and acid neutralization, produced by light calcination of natural magnesite. The product is not chemically modified beyond calcination, so it falls under other magnesium oxide in this tariff item.
2519.90.00Sintered Magnesia 92% with Iron Oxide
Sintered magnesia with 92% MgO and controlled iron oxide additions for BOF refractories, produced by dead-burning. The iron oxide is a natural impurity or minor addition that does not change the essential character, so it remains other magnesium oxide under this tariff item.
2519.90.00Turkish CCM Grade A Caustic Magnesite
Turkish caustic calcined magnesite Grade A for rubber and plastics reinforcement, produced by controlled low-temperature calcination. The product is magnesium oxide from natural magnesite, classifiable as other under this tariff item.
