CCM 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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the dust is from crude magnesite, not calcined
Unprocessed magnesite dust is classified separately.

Import Tips & Compliance
• Confirm the dust is not contaminated with other materials during recovery
• Provide particle size distribution and MgO content
• Verify if the dust qualifies as a waste product with different duty treatment
Related Products under Tariff item 2519.90.00
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.
Caustic 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.
Caustic 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.
Dead-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.
Dead-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.
Electro-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.
