Product classification
HS code for Magnesium ingots: 8104.19
Magnesium, unwrought, containing less than 99.8% by weight of magnesium.
Classification of magnesium ingots under HS 8104.19
Magnesium ingots are classified under HS code 8104.19 because they represent unwrought magnesium that contains less than 99.8% magnesium by weight. This classification is primarily used for magnesium alloys, where other elements such as aluminum, zinc, or manganese are added to the base metal to improve structural properties or corrosion resistance. According to the General Rules of Interpretation (GRI), products are classified based on their chemical composition and physical state. As these items are in an unwrought form—meaning they have been cast into primary shapes like ingots, billets, or slabs but have not been further worked—they fall under the 'other' subcategory of unwrought magnesium. The Harmonized System places these in Chapter 81, which covers other base metals and cermets, specifically distinguishing between pure magnesium and alloyed versions.

Codes often confused with 8104.19
Common mistake. A frequent error is classifying these goods under HS code 8104.11, which is reserved strictly for unwrought magnesium containing at least 99.8% magnesium by weight (pure magnesium). Another common mistake involves HS code 8104.20, which covers magnesium waste and scrap; however, ingots are considered primary products, not waste. Additionally, some importers confuse these with aluminum alloys under 7601 if the magnesium content is not the predominant weight factor.
Top exporters and importers of HS 810419 (the code used for magnesium ingots), 2025
In 2025, the largest exporter of HS 810419 (the code used for magnesium ingots) in UN Comtrade data was China, with 60% of world exports; the largest importer in UN Comtrade data was the United States, with 21% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

Questions about magnesium ingots
What is the HS code for Magnesium ingots?
The HS code for Magnesium ingots is 810419 (Magnesium; unwrought, containing less than 99.8% by weight of magnesium). The HS code for magnesium ingots containing less than 99.8% magnesium by weight is 8104.19. If the purity is higher, it falls under 8104.11.
How do I classify Magnesium ingots for customs?
Magnesium ingots is classified under HS code 810419 — Magnesium; unwrought, containing less than 99.8% by weight of magnesium. This is a 6-digit subheading level code.
Does the shape of the ingot affect the classification?
No, as long as the metal is unwrought and cast into a primary form like an ingot, slab, or billet, the shape does not change the 8104.19 classification.
Which countries are the top exporters of magnesium ingots (HS 810419)?
In 2025, the top exporters of HS 810419 (the code used for magnesium ingots) in UN Comtrade data were China ($266M, 60% of world exports), South Korea ($42M) and Czechia ($39M). World exports came to about $445M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
