More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If coarse iron ore particles dominate
Pyrrhotite as iron sulfide may classify under coarse iron ores if precious content is trace.
If for sodium sulfide flotation reagents byproduct
Processing chemicals recovered during concentration become inorganic sulfides.
If refined to metal powder
Unwrought rhodium powder from smelting enters Chapter 71 as precious metal.

Import Tips & Compliance
• Check OFAC sanctions compliance for Russian-sourced PGM ores requiring specific licenses
• Declare pyrrhotite's acid-mine drainage potential in environmental impact documentation
• Use nitrogen blanketing during storage to prevent spontaneous heating of sulfide concentrates
