Products classified under HTS 3824.99.93.86
Magnesium Desulfurization Powder for Steel
A powdered mixture containing magnesium designed for injection into molten steel to remove sulfur impurities during steelmaking. This reagent reacts with sulfur to form magnesium sulfide slag, improving steel quality. Classified under HTS 3824.99.93.86 as a chemical mixture containing magnesium used specifically as a desulfurization reagent.
Deep Desulfurization Magnesium Alloy Powder
Specialty powder blend with magnesium alloys for deep desulfurization in secondary steel refining processes like ladle metallurgy. Achieves ultra-low sulfur levels in high-grade steels. Classified in 3824.99.93.86 as a magnesium-containing reagent for this purpose.
LadleMag Desulfurizer Capsules
Encapsulated magnesium mixture for precise ladle addition in steel desulfurization, minimizing magnesium loss and optimizing reaction. Used in continuous casting steel production. Meets HTS 3824.99.93.86 criteria for magnesium desulfurization reagents.
Blast Furnace Magnesium Desulfurization Shot
Small shot-form magnesium mixtures injected into blast furnace hot metal streams for sulfur reduction before BOF charging. High efficiency in large-scale ironmaking. HTS 3824.99.93.86 covers these specialized magnesium reagents.
Mag-C Injection Desulfurizer for Hot Metal
A magnesium-carbon based granular mixture injected into ladles of hot metal for sulfur removal in iron and steel production. The magnesium reacts selectively with sulfur while carbon aids dispersion. Falls under HTS 3824.99.93.86 due to its magnesium-containing composition tailored for desulfurization.
Mg-P Desulfurization Reagent Granules
Granular mixture of magnesium and phosphorus compounds used in blast furnace hot metal treatment to desulfurize prior to steelmaking. Provides efficient sulfur capture with controlled reaction rates. HTS 3824.99.93.86 applies to such magnesium-containing desulfurization preparations.
