Product classification
HS code for Magnesium granules: 8104.30
Magnesium, raspings, turnings and granules, graded according to size, powders.
Classification of magnesium granules under HS 8104.30
Magnesium granules, raspings, and powders are classified under HS code 8104.30. This classification is part of Chapter 81, which covers "Other base metals; cermets; articles thereof." The specific subheading 8104.30 is designated for magnesium in these specific physical forms, provided they are graded according to size. This includes turnings and raspings that have been processed into uniform dimensions. The classification is based on the physical state of the metal rather than its chemical purity. These materials are often used in pyrotechnics, metallurgy as a deoxidizer, or in the production of Grignard reagents. The Harmonized System distinguishes these small-form particles from unwrought bulk metal because of their unique handling requirements and industrial applications.

Codes often confused with 8104.30
Common mistake. Magnesium granules are often misclassified under 8104.11 or 8104.19, which are for unwrought magnesium in bulk forms like ingots. Another common error is using 3824.99 for chemical mixtures; however, if the product is essentially magnesium in granular form, 8104.30 is the more specific and correct code. It is also important not to confuse these with magnesium waste and scrap, which falls under 8104.20.

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).
