Products classified under HTS 2620.60.10.00
Arsenic-Bearing Copper Smelter Slag
Residue from copper smelting processes containing significant arsenic content, primarily used in the extraction of arsenic through specialized hydrometallurgical methods. This slag falls under HTS 2620.60.10.00 as it is exclusively employed for arsenic recovery and not for metal extraction or other chemical manufacturing. It meets chapter note requirements for arsenic-containing residues used only for arsenic compound production.
Gold Refinery Arsenic Ash
Fine ash residue generated during gold refining roaster operations, rich in arsenic trioxide precursors, used solely for arsenic chemical compound manufacturing. Classified under HTS 2620.60.10.00 due to its specific industrial application in arsenic recovery circuits. Excludes use in metal extraction per legal heading definitions.
Lead Smelter Arsenical Dross
Dross residue from lead smelting containing arsenic compounds, recovered specifically for arsenic extraction via leaching processes. This material qualifies for HTS 2620.60.10.00 as it serves no other industrial purpose beyond arsenic chemical production. Complies with heading 2620 limitations excluding iron/steel manufacture residues.
Arsenic-Rich Zinc Roast Clinker
Clinker from zinc roasting operations with high arsenic content, destined exclusively for arsenic recovery plants producing arsine gas or compounds. Falls precisely under HTS 2620.60.10.00 meeting the 'used only for extraction of arsenic' criterion in official descriptions. Not suitable for direct metal recovery.
Precious Metal Tailings Arsenic Residue
Arsenic-concentrated tailings from precious metal cyanidation circuits, used solely in dedicated arsenic chemical recovery facilities. HTS 2620.60.10.00 classification applies due to exclusive arsenic extraction purpose and compliance with slag/residue definitions. Excludes general mine tailings.
Arsenopyrite Flotation Tailings Concentrate
Concentrated arsenic residue from arsenopyrite ore flotation, processed exclusively for arsenic trioxide production via roasting. Meets HTS 2620.60.10.00 requirements as industrial residue used only for arsenic chemical manufacture. Distinguished from raw mineral ores.
Secondary Arsenic Recovery Furnace Ash
Ash from secondary recovery furnaces processing arsenic-contaminated industrial wastes, used only for final arsenic compound isolation. Classified under HTS 2620.60.10.00 per specific use limitation excluding municipal incinerator ash. High purity arsenic content verified by assay.
