Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If granulated slag from tellurium recovery
Smelter byproducts from telluride treatment become granular residues under 2618.
If sulfate minerals dominate
Oxidized sulfate gangue materials classify as inorganic chemicals.
If refined tellurium dore bars
Recovered tellurium-gold doré becomes monetary gold equivalent.

Import Tips & Compliance
• Include oxidation state analysis (gossan vs sulfide) for appropriate processing declarations
• Monitor arsenic content from scorodite minerals for DOT hazardous material shipping
• Use silica flour additives in bulk bags to prevent dust and segregation during transit
