Gold-Bearing Copper Smelter Residue
Residues from copper smelting processes containing recoverable gold along with arsenic and other metals, not advanced in value or condition. Classified under HTS 2620.99.7580 as unprocessed slag-like residues primarily used for gold extraction in industry. Excludes residues treated for metal recovery if over 2% copper, lead, or zinc.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily copper smelting residues without significant gold
Copper smelter residues fall under heading 2616 if not fitting 2620's slag/ash criteria for arsenic or multi-metal compounds.
If derived from municipal waste incineration
Ash/residues from household waste incineration are excluded from 2620 and classified separately in 2621.
If processed into gold sweepings or filings
Advanced processing into jewelry waste shifts classification from unrefined residues to Chapter 71 waste/scrap.

Import Tips & Compliance
• Provide detailed assay reports certifying gold content and confirming residues are not advanced in value or treated for copper/lead/zinc recovery if exceeding 2%
• Verify chapter note compliance by documenting industrial use for metal extraction; avoid classification issues with municipal waste ash
• Declare exact metal content without deductions per statistical notes to prevent valuation disputes
