99.9% Magnesium Pouring Cakes
Large flat cakes of unwrought magnesium poured directly from electrolysis, containing at least 99.8% purity for remelting in foundries. This primary form is specifically covered by HTS 8104.11.00.00 for high-purity unwrought magnesium.
Import Duty Rates by Country of Origin
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.
Not sure which classification is right?
The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
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
