Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing 99.8%+ but in powder or flake form
Granular/ powder presentations of magnesium are distinctly classified.
If cakes further machined or profiled
Any fabrication turns unwrought metal into 'other articles'.
If electrolytic residues or crusts
Production by-products remain in slag/ash chapter, not refined metal.

Our AI classifier can analyze your specific product and recommend the correct HTS code with confidence.
Import Tips & Compliance
• Document electrolytic cell origin to distinguish from alloy or scrap sources
• Prevent moisture exposure during transit to maintain purity integrity
• Consult HTS chapter notes on alloys to ensure no misdeclaration as 81-series
