Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the slabs have a magnesium content below 99.8% by weight
Unwrought magnesium with lower purity is classified under this sibling item.
If the slabs have been rolled, forged, or otherwise worked into articles
Wrought magnesium products and articles are classified under this tariff item.

The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Provide a certificate of analysis confirming magnesium content ≥99.8% by weight to avoid disputes at the border
• Ensure the slabs are declared as unwrought, not as plates or sheets, since they have not been rolled or worked
• Consider the end-use: if the slabs are for aerospace, additional CBSA documentation may be required for end-use verification
