HS code for Magnesium powder: 8104.30
Magnesium, raspings, turnings and granules, graded according to size, powders.
Classification of magnesium powder under HS 8104.30
Magnesium powder is classified under HS code 8104.30, which falls within Chapter 81 of the Harmonized System. This chapter is dedicated to "Other base metals; cermets; articles thereof." Specifically, heading 81.04 covers magnesium and articles of magnesium, including waste and scrap. Subheading 8104.30 is reserved for magnesium raspings, turnings, and granules that have been graded according to size, as well as powders. The classification process for these materials depends heavily on the physical state and the processing the metal has undergone. Unlike unwrought magnesium, which is classified by its purity and typically arrives in large, solid forms like ingots, the products under 8104.30 are characterized by their particulate nature. This includes fine powders used in chemical synthesis or pyrotechnics, as well as coarser granules and turnings resulting from machining processes, provided they have been sorted or graded by size. The Harmonized System's General Rules for Interpretation (GRI) require that products be classified according to the terms of the headings. For magnesium, the distinction between a "powder" and "unwrought metal" is a primary factor. If the magnesium is in a finely divided state, it must be directed to this code rather than the general categories for raw metal. This code is essential for customs authorities to monitor the trade of reactive metals, which often have specific safety and transport regulations due to their flammability in powder form.

Codes often confused with 8104.30
Common mistake. Magnesium powder is frequently confused with unwrought magnesium under HS codes 8104.11 or 8104.19. The distinction lies in the form; 8104.11 is for ingots containing at least 99.8% magnesium, while 8104.30 is for particulate forms. It is also sometimes misclassified as magnesium oxide (HS code 2825.90), which is a chemical compound rather than the base metal in powder form.
Top exporters and importers of HS 810430 (the code used for magnesium powder), 2025
In 2025, the largest exporter of HS 810430 (the code used for magnesium powder) in UN Comtrade data was China, with 71% of world exports; the largest importer in UN Comtrade data was Canada, with 18% 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).
