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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If prepared for foundry molds rather than desulfurization
Mixtures for foundry mold binders are specifically under 3824.99.40, separate from desulfurization reagents.
If pure magnesium salts without mixture additives
Salts of zinc or other metals in 2841 exclude complex mixtures designed for industrial desulfurization.
