Roasted Copper-Zinc Flue Dust from Japan
Roasted copper-zinc flue dust is a fine particulate residue captured from the roasting of copper concentrates that also contain zinc. It consists mainly of copper compounds and is used industrially for the recovery of metals or the manufacture of metal chemical compounds. This product falls under tariff item 2620.30.00 because it is a slag, ash or residue containing mainly copper, other than from the manufacture of iron or steel.

Import Tips
• Ensure the flue dust is not derived from iron or steel manufacturing, as such residues are classified elsewhere
• Be prepared to provide a certificate of analysis showing the copper content exceeds other metals to support the 'mainly copper' classification
• Verify whether the product contains hazardous substances requiring an Environmental Compliance Certificate under Canadian regulations
