Caustic Calcined Magnesite Powder
Fine powder produced by calcining natural magnesite at moderate temperatures to yield reactive magnesium oxide with some residual CO2. Classified under HTS 2519.90.20.00 as caustic calcined magnesite, distinct from dead-burned or fused magnesia due to its lower sintering temperature and higher reactivity.
Reactive Caustic Magnesite 90% MgO
Lightly calcined magnesite powder with 90% MgO content, used primarily in fertilizer production and acid neutralization. Falls under HTS 2519.90.20.00 because it's produced from natural magnesite via caustic calcination, retaining reactivity characteristics.
Greek Caustic Calcined Magnesite Lumps
Lump form caustic calcined magnesite from Grecian deposits, partially calcined for steelmaking slag conditioning. HTS 2519.90.20.00 applies as it's 'other' magnesium oxide from natural magnesite via caustic process, not fused or fully sintered.
Turkish CCM Grade A Caustic Magnesite
Premium Turkish caustic calcined magnesite meeting CCM Grade A specs for rubber and plastics reinforcement. Classified HTS 2519.90.20.00 due to production via controlled low-temperature calcination of high-purity magnesite.
High Reactivity Caustic Magnesite for Animal Feed
Specially calcined magnesite providing bioavailable magnesium for livestock supplements. HTS 2519.90.20.00 because it's caustic calcined natural magnesite meeting feed-grade purity without pharmaceutical processing.
Caustic Calcined Magnesite 85/15 (MgO/SiO2)
85% MgO / 15% SiO2 caustic calcined blend for basic refractory brick production. Specific HTS 2519.90.20.00 classification as 'caustic calcined magnesite' despite silica content typical for refractory formulations.
