HS code for Magnesium turnings: 8104.30
Magnesium, raspings, turnings and granules, graded according to size, powders.
Classification of magnesium turnings under HS 8104.30
Magnesium turnings are classified under HS code 8104.30. This specific code is reserved for magnesium in the form of raspings, turnings, and granules that have been graded according to size, as well as powders. These materials are distinct from unwrought ingots because they consist of small particles or fragments. They are often the byproduct of machining magnesium parts or are manufactured specifically for use in pyrotechnics, chemical synthesis (such as Grignard reagents), or metallurgical processes. The classification under 8104.30 requires that the material be intentionally sized or processed into these particulate forms. The Harmonized System distinguishes these from general waste and scrap based on the uniformity and intended application of the particles. Proper classification is vital due to the flammable nature of magnesium in these high-surface-area forms.

Codes often confused with 8104.30
Common mistake. Magnesium turnings are frequently misclassified under HS code 8104.20, which is for magnesium waste and scrap. While turnings can be a form of scrap, if they are graded by size or sold for a specific industrial use, 8104.30 is more appropriate. They are also sometimes confused with 8104.90, which covers finished articles of magnesium. Additionally, if the powder is mixed with other chemicals for pyrotechnics, it might fall under Chapter 36.
Top exporters and importers of HS 810430 (the code used for magnesium turnings), 2025
In 2025, the largest exporter of HS 810430 (the code used for magnesium turnings) 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).
