Copper Anode Slime Lead Residue
Precious metal-rich slime from copper anode refining, mainly copper with lead and arsenic, processed for extraction. HTS 2620.30.0020 covers this as copper-main ash/residue per chapter notes, reporting lead content statistically.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily precious metal content
Precious metal residues in 2616 take precedence over base metal slags in 2620.
If sold as a set with other residues
Mixed slag sets may classify under 2620.90 if no principal metal dominates.

Import Tips & Compliance
• Declare precious metal traces separately if applicable; ensure slime state (not refined) for 2620; pitfall: confusing with 2616 for precious metal residues
