Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If DC arc low-carbon silico-manganese grades
LC SiMn specifically provided for in 7202.50 due to distinct electric furnace low-C process.
If imported as manganese silicate furnace matte
Intermediate furnace products not fully reduced classified as manganese residues in Chapter 26.
If slag-modified for specific deoxidation profiles
Intentionally modified slag chemistry constitutes chemical treatment per Chapter 72 further-worked note.

Import Tips & Compliance
• DC arc grades typically lower Al/Ca; highlight in certificates for premium pricing justification
• South African DC arc FeSiMn dominates market; verify smelter certifications for quality assurance
• Thermal shock resistance better than AC furnace grades; note in technical datasheets
