Products classified under HTS 7106.91.10.20
Gold-Silver Dore Bars
Dore bars are semi-refined bullion containing a mixture of gold and silver, typically produced from mining operations before full separation. Classified under HTS 7106.91.10.20 as unwrought silver dore, where silver is the predominant precious metal by weight per Chapter 71 Note 5 rules. These impure bars require further refining to separate the metals.
Unrefined Silver Dore Ingots
Impure ingots from primary silver mining, assaying 70-80% silver with gold impurities, in unwrought form ready for electrolytic refining. Fits HTS 7106.91.10.20 as dore bullion where silver predominates. Not suitable for fabrication without purification.
Electrowinning Silver Dore Bars
Dore bars from electrowinning cells in silver heap leach operations, impure with 80% Ag and 15% Au. Unwrought form under HTS 7106.91.10.20 due to silver predominance and lack of full refinement. Used by mints and refiners.
Bolivian Potosi Silver Dore
Traditional dore from Potosi mines, high-grade silver (85% Ag) with doré characteristics from amalgamation. Unwrought silver bullion under HTS 7106.91.10.20. Historic import source for U.S. refineries.
Heap Leach Silver Dore Pours
Poured dore from cyanide heap leaching of silver oxides, 72% Ag. Meets unwrought dore criteria for 7106.91.10.20.
Miller Process Silver Dore
Partially refined dore from Miller chlorination, impure silver phase. HTS 7106.91.10.20 as unwrought.
Peruvian Silver Dore Bars
Dore from Yanacocha operations, silver-gold mix. Silver dominant for 7106.91.10.20.
Mexican Fresnillo Silver Dore
World's largest silver producer dore, 78% Ag. Unwrought 7106.91.10.20.
Mining Dore Bullion from Polymetallic Ores
Dore produced from polymetallic sulfide ores via cyanidation, containing 75% silver, 20% gold, and trace metals in bar form. HTS 7106.91.10.20 applies to this unwrought silver-dominant dore for import by U.S. refineries. Represents intermediate stage post-smelting.
Secondary Silver Dore from Recycling
Dore bullion recovered from e-waste and photographic film recycling, 65% silver with gold, in unwrought cast form. Classed as silver dore HTS 7106.91.10.20 when silver predominates post-smelting. Growing import for sustainable refining.
