Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the slag contains mainly copper
Copper-containing residues are classified in a separate subheading.
If the slag is primarily for silver recovery
Residues for precious metal recovery are classified in heading 71.12.

Import Tips & Compliance
• Document the electrowinning process to show the slag is a by-product, not a finished product
• Confirm the zinc content is the primary metal for classification
• Check if the silver content requires separate reporting or permits
