Product classification
HS code for Sodium peroxide: 2815.30
Peroxides of sodium or potassium.
Classification of sodium peroxide under HS 2815.30
Sodium peroxide is classified under HS code 2815.30. This classification is found within heading 28.15, which is titled "Sodium hydroxide (caustic soda); potassium hydroxide (caustic potash); peroxides of sodium or potassium." Sodium peroxide (Na2O2) is an inorganic compound produced by treating sodium with excess oxygen. It is a powerful oxidizer and reacts violently with water to form sodium hydroxide and oxygen. The Harmonized System groups the peroxides of these specific alkali metals (sodium and potassium) together with their respective hydroxides because of their chemical relationship and industrial similarities. Classification is straightforward under GRI 1, as the product name is explicitly mentioned in the heading text. It is typically traded in granular or powder form and used in bleaching wood pulp, extracting minerals from ores, and in breathing apparatuses to regenerate oxygen from carbon dioxide.

Codes often confused with 2815.30
Common mistake. Sodium peroxide is often misclassified under HS code 2815.11 or 2815.12, which are for sodium hydroxide (caustic soda). While sodium peroxide reacts to form sodium hydroxide, they are distinct chemicals. Another common error is 2847.00, which is for hydrogen peroxide. While both are peroxides, 2847.00 is limited to hydrogen peroxide only. Finally, it should not be confused with sodium oxide (2825.90), which lacks the peroxo (O-O) linkage.
Top exporters and importers of HS 281530 (the code used for sodium peroxide), 2025
In 2025, the largest exporter of HS 281530 (the code used for sodium peroxide) in UN Comtrade data was the United Kingdom, with 24% of world exports; the largest importer in UN Comtrade data was South Africa, with 9.3% 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).
