Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If granulated and suitable for cement manufacture
Heading 2618 covers specific granulated slags usable in cement, regardless of metal content.
If not containing mainly zinc
Other metal-mainly residues (e.g., copper or mixed) fall under 2620.99 with lead content subheading.
If refined into metal compounds for chemical use
Processed into finished inorganic compounds of metals shifts to Chapter 28 salts/oxides.
