Product classification
HS code for Magnesium peroxide: 2816.10
Hydroxide and peroxide of magnesium.
Classification of magnesium peroxide under HS 2816.10
Magnesium peroxide is classified under HS code 2816.10. This classification is part of Chapter 28, which is dedicated to inorganic chemicals, precious metals, and rare-earth metals. Specifically, 2816.10 covers the hydroxide and peroxide of magnesium. Unlike magnesium oxides found in Chapter 25, magnesium peroxide (MgO2) is a chemically synthesized compound used for its oxygen-releasing properties. It is typically produced through the reaction of magnesium salts with hydrogen peroxide. The classification is determined by the chemical structure of the compound as a peroxide. It is often used in environmental applications, such as soil remediation, or as a stabilizer in various industrial processes. Because it is a distinct chemical compound rather than a processed mineral earth, it must be classified in the chemical section of the Harmonized System.

Codes often confused with 2816.10
Common mistake. The most common misclassification occurs with HS code 2519.90 (magnesium oxide), as the names are chemically similar, but the oxygen content and chemical behavior differ significantly. It is also sometimes confused with HS code 3824.99, which covers miscellaneous chemical products, or HS code 3004.90 if the peroxide is packaged for retail sale as a medicament. However, as a bulk chemical substance, 2816.10 is the correct heading.
Top exporters and importers of HS 281610 (the code used for magnesium peroxide), 2025
In 2025, the largest exporter of HS 281610 (the code used for magnesium peroxide) in UN Comtrade data was Russia, with about 17% of world exports; the largest importer in UN Comtrade data was Germany, with 13% 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 marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
