Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If zinc content below threshold but still principal
Same code but statistical breakouts differ; no change in heading.
If derived from municipal waste incineration
Chapter notes exclude such ash/residues from 2620, placing in 2621.

Import Tips & Compliance
• Provide origin-specific mining permits and zinc content certification; test for lead co-contaminants
• Use moisture-proof containers to prevent carbonate decomposition
• Declare accurately to avoid penalties for underreported metal value
