Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing vanadium
Vanadium-bearing residues are excluded and classified separately in 2620.99.5060.
If primarily zinc ore residues
Zinc ores and concentrates, including certain residues, fall under Chapter 26 heading 2608.
If from incineration processes
Any ash/residues from incineration, even industrial, go to 2621 per chapter exclusion.

Import Tips & Compliance
• Document origin from non-ferrous smelting to avoid Chapter 72 misclassification
• Avoid packaging for retail; bulk industrial shipments maintain residue status
• Monitor for zinc content thresholds that could trigger recovery treatment rules
