Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If lead content predominates with silver
Silver content in lead-bearing zinc ores uses a separate statistical breakout.
If used for metal extraction from slag
Chapter notes limit 2620 to industrial slag/ash for metal or chemical recovery, excluding ore concentrates.
If for silver recovered as semi-manufactured bars
Processed silver forms move to Chapter 71 precious metals after extraction.

Import Tips & Compliance
• Provide laboratory assays confirming silver percentage; discrepancies can lead to reclassification or penalties
• Declare as concentrate only if beneficiated but not chemically treated, distinguishing from slag under 2620
• Check for arsenic content, as residues with arsenic shift to heading 2620 per chapter exclusions
