HS code for Unwrought magnesium: 8104.19
Magnesium, unwrought, containing less than 99.8% by weight of magnesium.
Classification of unwrought magnesium under HS 8104.19
Unwrought magnesium is classified under HS code 8104.19 when the magnesium content is less than 99.8% by weight. This classification falls within Chapter 81, which covers other base metals and cermets. The determination for this specific code is based on the chemical composition and the physical state of the metal. The term unwrought refers to the metal in its primary form, such as ingots, blocks, or slabs, which have not been further worked beyond casting or sintering. Because the purity level is below the 99.8% threshold, these items are typically magnesium alloys rather than pure magnesium. The Harmonized System distinguishes between high-purity magnesium and alloys to monitor trade flows of industrial-grade materials versus specialized high-purity inputs. For classification purposes, the weight of the magnesium must be the predominant component, but the presence of alloying elements like aluminum, zinc, or manganese in quantities that bring the magnesium purity below 99.8% necessitates the use of 8104.19 rather than the code for pure magnesium.

Codes often confused with 8104.19
Common mistake. A frequent error is classifying these alloys under HS code 8104.11, which is strictly reserved for unwrought magnesium containing at least 99.8% magnesium by weight. Importers also confuse unwrought forms with magnesium waste and scrap, which should be classified under 8104.20. Furthermore, if the magnesium has been processed into specific shapes like wire or plates, it must be classified under 8104.90 as an article of magnesium rather than an unwrought form. Raspings, turnings, and granules are also distinct and belong under 8104.30.
Top exporters and importers of HS 810419 (the code used for unwrought magnesium), 2025
In 2025, the largest exporter of HS 810419 (the code used for unwrought magnesium) 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).
