Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If from iron or steel but aluminum containing
Iron/steel residues containing aluminum go to 2620.19, separate from non-steel 2620.40.
If chemically processed for salts
Salts of metals extracted from residues become Chapter 28 chemicals, not raw materials.
If containing mainly silicon
Silicon-dominant residues shift within 2620 but different subheading from aluminum-based.

Import Tips & Compliance
• Require process flow documentation proving aluminum origin; report vanadium without deductions
• Pitfall: blending with steel slag risks reclassification
