Bismuth Nitrate Catalyst from Japan
Bismuth nitrate is used as a catalytic preparation in organic synthesis reactions like esterification and oxidation processes. It falls under HTS 3815.90.1000 as a reaction initiator consisting wholly of inorganic bismuth compounds, not elsewhere specified. This catalyst enables milder reaction conditions compared to traditional acids.

Import Tips
• Provide chemical composition analysis certifying 100% inorganic bismuth content to qualify under this subheading
• Include Safety Data Sheets (SDS) and end-use statements proving catalytic application, not as reagents
• Verify no organic additives exceed trace levels to prevent reclassification under 3815.90.2000
