Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

2601.20.00Same rate: 35%

If roasted and mainly iron-based

Roasted lead ores shift to 2601, differing from unprocessed leaded industrial residues.

2620.99.50Lower: 25% vs 35%

If not mainly lead but still containing gold

Other metal-containing residues without lead predominance fall under 2620.99.
