Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If lead ores in raw form
Unprocessed lead ores like galena classify under 2607, not processed residues in 2620.
If ferrous alloy additions
If used in steelmaking, shifts to Chapter 72 ferrous slags.
If hard zinc spelter residues
Zinc-dominant lead byproducts may fall under 2621 if not fitting 2620 lead criteria.

Import Tips & Compliance
• Document ore processing chain to affirm non-steel manufacture per chapter exclusions
• Use independent labs for silver content verification; avoid deductions in reporting
• Check for coarse particle definitions if blended with iron ores, risking 2601 misclassification
