Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for cobalt-bearing silver ores
Presence of cobalt as principal associate metal redirects to specific cobalt ore heading.
If roasted during processing
Calcined or roasted silver concentrates move to heading 2613 for chemically treated products.
If derived from municipal waste incineration
Ash/residues from waste processing excluded from 2620 and classified here per chapter notes.

Import Tips & Compliance
• Declare exact copper content per statistical note requirements using independent lab assays
• Verify if ore meets 'concentrate' criteria to distinguish from unprocessed ores under other subheadings
• Prepare for potential inspections on radioactivity or hazardous mineral content in polymetallic ores
