Product classification
HS code for Antimony oxide: 2825.80
Antimony oxides.
Classification of antimony oxide under HS 2825.80
Antimony oxide is classified under HS code 282580 because this subheading specifically covers "Antimony oxides." Chapter 28 of the Harmonized System is dedicated to inorganic chemicals, and antimony oxide is a well-defined inorganic compound. This classification is precise, encompassing various stoichiometric forms of antimony oxide, such as antimony trioxide (Sb2O3) and antimony pentoxide (Sb2O5), which are produced through chemical processes rather than being naturally occurring ores. The code reflects its identity as a manufactured chemical product with specific industrial applications.

- Antimony pentoxide (Sb2O5)
- Synthetic antimony oxides in powder or granular form
- Also under 2825.80
- Chemtura (flame retardants)
- Albemarle (flame retardants)
- ICL Group (flame retardants)
- Campine (antimony products)
Codes often confused with 2825.80
Common mistake. A common misclassification risk for antimony oxide involves HS code 261710, which is for "Antimony ores and concentrates." Antimony oxide is a refined chemical compound, not a raw ore, even though it can be derived from antimony ore. Therefore, classifying antimony oxide as an ore would be incorrect. Another potential confusion arises with HS code 282590, which covers "Other oxides of other metals." However, since antimony oxides have a specific and dedicated subheading (282580), the more general 282590 should not be used for these products.
Top exporters and importers of HS 282580 (the code used for antimony oxide), 2025
In 2025, the largest exporter of HS 282580 (the code used for antimony oxide) in UN Comtrade data was Belgium, with 31% of world exports; the largest importer in UN Comtrade data was the United States, with 33% 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).
