Product classification
HS code for High purity magnesium: 8104.11
Magnesium, unwrought, containing at least 99.8% by weight of magnesium.
Classification of high purity magnesium under HS 8104.11
High purity magnesium is classified under HS code 8104.11. This code is specifically designated for unwrought magnesium that contains at least 99.8% magnesium by weight. In the context of the Harmonized System, \"unwrought\" refers to primary forms such as ingots, blocks, or slabs that have been produced by casting or sintering and have not been further worked. The high purity requirement (99.8%) is a strict threshold; if the magnesium content is lower, it is considered an alloy or a lower-grade metal. This material is essential in specialized industries, including aerospace and chemical synthesis, where impurities can compromise the structural integrity or chemical reactivity of the final product. The classification is governed by the Section XV notes and the specific subheading text for Chapter 81.

Codes often confused with 8104.11
Common mistake. High purity magnesium is often confused with magnesium alloys, which are classified under 8104.19. Alloys contain less than 99.8% magnesium and include other elements like aluminum or zinc to enhance specific properties. Another common error is classifying magnesium waste and scrap under this code; scrap is correctly classified under 8104.20. Additionally, magnesium raspings, turnings, and granules are classified under 8104.30, even if they are of high purity, because they are not in \"unwrought\" primary forms.
Top exporters and importers of HS 810411 (the code used for high purity magnesium), 2025
In 2025, the largest exporter of HS 810411 (the code used for high purity magnesium) in UN Comtrade data was China, with 76% of world exports; the largest importer in UN Comtrade data was the United States, with 15% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 810411, not only high purity magnesium.

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).
