Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If refined silver semi-manufactures
Extracted and refined silver products become Chapter 71 precious metal articles, not raw residues.
If containing mainly lead instead of copper
Lead-dominant metal residues fall under 2620.19, differentiated by primary metal content.
If other metals, not mainly copper
Residues with other dominant metals (e.g., zinc) classified under 2620.99 subheading.
