Copper Smelter Slag with 15% Copper Content
Residue from copper smelting operations containing primarily copper metal and compounds, with an assayed copper content of 15%. Classified under HTS 2620.30.0010 due to its main copper composition and use in metal recovery industries. Excludes iron/steel slags and municipal waste ash per chapter notes.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If processed into copper bearing materials suitable for metal recovery
High-purity copper residues shift from slag/residues to copper waste/scrap in Chapter 74.
If derived from municipal waste incineration
Chapter notes exclude such ash from 2620, directing to heading 2621 for waste residues.
If primarily from roasted copper ore processing
Roasted pyrites containing copper fall under 2613, differing from general smelter slag.

Import Tips & Compliance
• Provide certified assay reports specifying copper content without deductions, as per statistical notes
• Ensure documentation proves industrial use for metal extraction to avoid reclassification under 2621
• Verify absence of iron/steel origin to prevent shift to Chapter 26 headings for ferrous slags
