High-Grade Psilomelane Manganese Ore from Japan
Psilomelane is a manganese oxide mineral aggregate with over 47% manganese content by dry weight, often used in steel alloy production. This ferruginous ore falls under HTS 2602.00.0060 due to its high manganese concentration exceeding the 47% threshold. It is mined primarily in South Africa and Australia for industrial extraction.

Import Tips
• Obtain certified assay reports verifying manganese content ≥47% dry weight to confirm classification and avoid reclassification to lower subheadings
• Ensure proper documentation of dry weight basis calculations, as moisture content can affect reported manganese percentage during customs valuation
• Declare iron content accurately if ferruginous; common pitfalls include underestimating impurities leading to duty disputes
