Vanadium Slag from Petroleum Refining
Residue slag generated during petroleum refining processes, containing vanadium compounds and trace metals but not advanced in value. Classified under HTS 2620.99.7520 as vanadium bearing material that is a residue not treated for metal recovery and meets copper/lead/zinc content limits. Used in industry for potential vanadium extraction.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing over 2% copper, lead, or zinc
Materials treated or intended for recovery of those specific metals fall under the prior subheading in 2620.99.75.
If primarily antimony-bearing residues
Slag or residues mainly containing antimony compounds are classified in Chapter 26 heading for antimony ores/residues.
If derived from iron or steel manufacture
Ferrous slag from iron/steel production is excluded from heading 2620 and goes to Chapter 72.

Import Tips & Compliance
• Obtain assay certificates verifying vanadium content and confirming less than 2% copper, lead, or zinc to avoid reclassification
• Declare exact metal content per statistical notes; provide origin certificates for slag residues
• Avoid common pitfalls like misdeclaring as advanced material, which shifts to other 2620 subheadings
