Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If purified into inorganic lead compounds
Processed to chemical purity level moves from residue to specific chemical compounds in Chapter 28.
If containing mainly other metals, not lead
Heading 2620 structure specifies 'mainly lead'; lower lead shifts to other metal subheadings.
If incorporated into waste batteries
Lead sludges in battery scrap classified under lead-acid battery waste heading.
