Ferro-Magnesium Base Ingots

> These magnesium-rich ingots contain trace ferrosilicon and are used for steel desulfurization applications. They are classified as unwrought magnesium under tariff item 8104.19.00 because they contain at least 99% magnesium by weight. They are used in steel ladle metallurgy.

Import Tips & Compliance

• > Verify the magnesium content is at least 99% by weight to ensure classification as "not alloyed" magnesium

• If the ferrosilicon content exceeds 1%, the ingots may be considered alloyed and classified elsewhere

• Provide a certificate of analysis to support the classification

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.
