Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If vanadium or tungsten bearing
Specific metal compositions have dedicated subheadings within 2620.99.
If refined copper recovery product
Post-recovery copper metal classifies under Chapter 74, not residue.
If calcined to zinc oxide
Thermal processing converts residue to Chapter 28 oxide chemical.

Import Tips & Compliance
• Flue dust requires HEPA-filtered transport; airborne risks trigger additional inspections
• Link to specific refinery process docs to prove non-municipal, non-steel origin
