Products classified under HTS 2620.30.00.30
Copper Smelter Zinc Slag
Residue from copper smelting processes containing primarily copper with significant zinc content, classified under HTS 2620.30.00.30 due to its metal compounds and use in metal recovery. It meets Chapter 2620 notes as slag used for extracting metals like zinc and copper.
Leaching Residue with Zinc Content
Ash-like residue from hydrometallurgical leaching of copper ores, mainly copper with zinc compounds, under HTS 2620.30.00.30 for its metal recovery applications. Fits heading 2620 as industrial residue for chemical compound manufacture.
Brass Foundry Zinc Ash
Ash generated in brass (copper-zinc alloy) foundry operations, containing mainly copper with zinc, classified in HTS 2620.30.00.30 for recovery of metals. Qualifies under Chapter 2620(b) for arsenic/metal extraction uses.
Copper Electrolysis Zinc Residue
Residues from copper electrolysis containing zinc impurities, mainly copper matrix, under HTS 2620.30.00.30 for industrial metal reclamation. Aligns with Chapter 2620 for residues used in compound production.
Secondary Copper Zinc Skimmings
Skimmings from secondary copper recycling with zinc content, primarily copper-based, in HTS 2620.30.00.30 for metal extraction. Excluded from iron/steel per hierarchy and used industrially.
Roasted Copper-Zinc Flue Dust
Flue dust from roasting copper concentrates with zinc, mainly copper, under HTS 2620.30.00.30 as arsenic/metal residue for recovery. Chapter 2620 applies for industrial chemical uses.
