Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for industrial use but primarily chromium/tungsten compounds
Other metal residues like chromium slag fall under separate 2619 heading.
If derived from steel mill zinc coating processes
Ferrous slag residues classify under Chapter 72 iron/steel headings.
If calcined to zinc oxide purity
Processed to oxide form shifts to Chapter 28 inorganic chemicals.

Import Tips & Compliance
• Include process flow documentation showing non-iron/steel origin to justify classification
• Report metal content via assay without deductions; mismatches cause delays
• Check for EPA-equivalent certifications if arsenic levels trigger environmental scrutiny
