Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily for arsenic extraction rather than zinc
Subheading differentiates based on primary recovery target metal.
If chemically treated as residual waste from organic processes
Advanced processing may move it to Chapter 38 for chemical residuals.
If from municipal waste incineration
Chapter note excludes incineration ash; shifts to heading 2621 if applicable.
