Extrusion-Grade Magnesium Blocks
> These large rectangular magnesium blocks are prepared for direct-feed extrusion presses. They are unwrought magnesium in an "other" form, excluding powder and refined forms, and are classified under tariff item 8104.19.00. They are critical for producing magnesium structural profiles.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the blocks are alloyed with other metals
Alloyed magnesium is classified separately from unwrought magnesium.

Import Tips & Compliance
• > Confirm the blocks are not considered "plates, sheets, strip, or foil" as defined in Section Note 9; if they have a flat rectangular cross-section, they may be classified elsewhere
• Ensure they are not alloyed; alloyed magnesium is classified under a different tariff item
• Keep records of the extrusion process to demonstrate they are unwrought

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
> 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.
Battery-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.
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.
Die Casting Magnesium T-Bars
> These T-shaped magnesium bars are designed for automated die casting furnace loading. They are unwrought magnesium in a primary form, not refined or powdered, and are classified under tariff item 8104.19.00. They serve as feedstock for producing consumer electronics housings.
