Desulfurization Magnesium Granules
> These coarse magnesium granules, less than 10mm in size, are used for steel ladle desulfurization injections. They are not classified as powder because they do not meet the 90% passing through a 1mm sieve test, so they fall under tariff item 8104.19.00 as unwrought "other" magnesium. They are critical for producing ultra-low sulfur steels.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the granules meet the powder definition (90% passing through 1mm sieve)
Powdered magnesium is classified separately from unwrought magnesium.

Import Tips & Compliance
• > Ensure the granules are not classified as powder; if 90% or more pass through a 1mm sieve, they fall under a different tariff item
• Provide sieve analysis results to support classification
• Confirm the granules are not alloyed; alloyed magnesium is classified separately

3D Printing Magnesium Ingots
> These are special purity magnesium ingots formulated for laser powder bed fusion 3D printing. They are unwrought magnesium in primary form, not yet atomized into powder, and therefore fall under tariff item 8104.19.00 as "other" unwrought magnesium. The ingots enable the production of complex lightweight structures through additive manufacturing.
Alloy Feedstock Magnesium Wedges
> These wedge-shaped magnesium pieces are used for controlled alloying in master alloy production. They are primary unwrought magnesium in a form other than powder or refined, thus classified under tariff item 8104.19.00. They are essential for creating magnesium alloys like AZ91D and AM60.
Anode-Grade Magnesium Slabs
