Zinc Smelter Slag with Copper Content
Residue from zinc smelting processes containing primarily zinc along with copper and arsenic compounds, used for metal recovery. Classified under HTS 2620.19.60.10 due to its main zinc content, copper presence, and industrial use in extracting metals. Excludes iron/steel slag and municipal waste ash per chapter notes.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing mainly other metals like lead instead of zinc
Heading 2620.99 covers slag with mainly non-zinc metals but still arsenic/metals for extraction.
If roasted and primarily zinc oxide form
Roasted zinc residues shift to Chapter 26 heading for metal oxide concentrates.
If from municipal waste incineration
Chapter note excludes such ash from 2620, directing to waste ash heading.

Import Tips & Compliance
• Provide assay certificates detailing copper and zinc content without deductions as per statistical notes for accurate quantity reporting
• Ensure documentation proves industrial use for metal extraction to avoid reclassification under heading 2621 for waste ash
• Verify absence of iron/steel origin to prevent misclassification under other slag headings
