Subheadings
Products classified under HTS 2616.90.00
Gold Bearing Quartz Ore
Crushed quartz ore containing visible gold particles and traces of other precious metals, mined primarily for gold extraction. Classified under HTS 2616.90.00 as 'other' precious metal ores and concentrates not specifically enumerated elsewhere in heading 2616. The ore requires milling and chemical processing to recover the precious metal content.
Platinum Group Metal Bearing Ore
Unprocessed ore from the Bushveld complex containing platinum, palladium, rhodium, and other PGE minerals in sulfide matrix. Falls under HTS 2616.90.00 as 'other' precious metal ores not classified under specific platinum subheadings. Typically requires flotation and smelting for metal recovery.
Palladium Rich Nickel-Copper Ore
Sulfide ore from Sudbury-type deposits containing palladium as byproduct with nickel and copper sulfides. HTS 2616.90.00 applies to this mixed precious/base metal ore where precious metals drive extraction economics. Processed via flotation to produce mixed concentrates.
Telluride Gold Ore Concentrate
Flotation concentrate from Cripple Creek-type deposits containing calaverite and sylvanite gold tellurides. Classified under HTS 2616.90.00 as precious metal ore concentrate not fitting specific gold subheadings. Requires pressure oxidation or roasting prior to cyanidation.
Mixed Precious Metal Gravels
Alluvial placer gravels from Fairbanks district containing fine gold, platinum, and palladium particles. HTS 2616.90.00 covers these unprocessed polymetallic precious sediments. Typically screened and gravity concentrated at destination.
Rhodium-Bearing Pyrrhotite Ore
Massive pyrrhotite ore from Norilsk containing byproduct rhodium in platinum group minerals. Falls under HTS 2616.90.00 for precious metal sulfide ores. Smelting produces high-value PGM-rich matte.
Silver-Lead Ore from Epithermal Veins
Vein-hosted galena-sphalerite ore with bonanza-grade silver from Creede district. HTS 2616.90.00 classification applies when silver recovery drives mine economics despite lead host. Flotation yields high-silver lead concentrates.
Gold-Tellurium Ore from Oxidation Zones
Supergene enriched gossan containing native gold and tellurides from Carlin trend. Classified HTS 2616.90.00 as complex precious metal ore requiring specialized metallurgy. Oxidized zones yield higher recovery rates.
PGE-Enriched Mafic Intrusions Ore
Layered mafic intrusion ore from Stillwater complex containing platinum, palladium, and chromite. HTS 2616.90.00 covers these reef-type precious metal deposits. Sequential flotation recovers PGE and chromite separately.
Bonanza Silver Vein Ore
High-grade silver vein material from Cobalt, Ontario containing native silver in quartz-carbonate gangue. Classified under HTS 2616.90.00 when not meeting silver ore specificity. Direct shipping ore for milling.
