8104.19.003D 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.
8104.19.00Alloy 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.
8104.19.00Anode-Grade Magnesium Slabs
> These corrosion-resistant magnesium slabs are designed for cathodic protection anodes in marine and offshore applications. They are primary unwrought magnesium, not refined or powdered, and are classified under tariff item 8104.19.00. The slabs serve as sacrificial anodes for pipelines and ships.
8104.19.00Battery-Grade Magnesium Slabs
> These ultra-pure magnesium slabs are used for magnesium-air battery electrode production. They are primary unwrought magnesium with high electrochemical performance, classified under tariff item 8104.19.00 as "other" unwrought magnesium. The slabs are not refined or in powder form.
8104.19.00Desulfurization Magnesium Granules
> These coarse magnesium granules, less than 10mm in size, are used for steel ladle desulfurization injections.
