Copper Smelter Slag with Gold Content
Residue from copper smelting operations containing primarily copper compounds along with recoverable gold content, used in the extraction of precious metals. Classified under HTS 2620.30.00.50 due to its main copper composition and gold assay quantity as per statistical notes. Excludes iron/steel manufacture residues and municipal waste ash.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If derived from municipal waste incineration
Chapter note excludes municipal waste ash from 2620, directing it to heading 2621 regardless of metal content.
If processed into copper matte or cement copper
Further refinement into copper-bearing materials shifts classification from slag/residues to Chapter 74 copper products.
If containing mainly roasted copper ores
Roasted copper ore residues fall under 2613, distinguished from unroasted or slag forms in 2620.

Import Tips & Compliance
• Provide detailed assay certificates specifying gold content without deductions as required by statistical notes
• Verify non-municipal waste origin to avoid reclassification to 2621
• Check for arsenic content declarations per chapter notes
