Product classification
HS code for Sodium permanganate: 2841.69
Salts, of oxometallic or peroxometallic acids, manganites, manganates and permanganates, other than potassium permanganate.
Classification of sodium permanganate under HS 2841.69
Sodium permanganate is classified under HS code 2841.69. This classification falls within heading 28.41, which covers salts of oxometallic or peroxometallic acids. Specifically, the 2841.6x series is dedicated to manganites, manganates, and permanganates. While potassium permanganate is the most common salt in this group and has its own specific subheading (2841.61), all other permanganates, including the sodium salt (NaMnO4), are classified under the residual category 2841.69. Sodium permanganate is highly soluble in water and is frequently traded as a 40% aqueous solution. It is used in water treatment, metal surface treatment, and as an etchant in printed circuit board manufacturing. The classification is determined by the metallic cation (sodium) and the oxometallic anion (permanganate). Because it is a separate chemically defined compound, it remains in Chapter 28 regardless of its concentration in water, as per Note 1 to Chapter 28.
- Covers
- Sodium permanganate crystalline form
- Sodium permanganate aqueous solutions (e.g., 40% concentration)
- Technical grade sodium permanganate for water purification
- Sodium permanganate used in electronics manufacturing
- Also under 2841.69
- Sigma-Aldrich Sodium Manganate
- BASF Catalysts (containing manganese compounds)
- Umicore Battery Materials (lithium manganate)
Codes often confused with 2841.69
Common mistake. The most frequent misclassification is HS code 2841.61, which is exclusively for potassium permanganate. Because potassium permanganate is more widely known, many importers default to this code. However, the sodium version is chemically distinct and must be in 2841.69. It is also sometimes confused with sodium manganate (Na2MnO4), though both fall under 2841.69, the chemical oxidation state differs. It should not be classified in Chapter 38 as a water treatment preparation if it is a pure chemical solution.
Top exporters and importers of HS 284169 (the code used for sodium permanganate), 2025
In 2025, the largest exporter of HS 284169 (the code used for sodium permanganate) in UN Comtrade data was China, with 63% of world exports; the largest importer in UN Comtrade data was South Korea, with 55% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 284169, not only sodium permanganate.

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).

Questions about sodium permanganate
What is the HS code for Sodium permanganate?
The HS code for Sodium permanganate is 284169 (Salts; of oxometallic or peroxometallic acids, manganites, manganates and permanganates, other than potassium permanganate). The HS code for sodium permanganate is 2841.69, which is the category for "other" permanganates besides potassium permanganate.
How do I classify Sodium permanganate for customs?
Sodium permanganate is classified under HS code 284169 — Salts; of oxometallic or peroxometallic acids, manganites, manganates and permanganates, other than potassium permanganate. This is a 6-digit subheading level code.
Why is sodium permanganate not in the same code as potassium permanganate?
The Harmonized System provides a specific subheading (2841.61) for potassium permanganate due to its high trade volume and its status as a precursor chemical under international monitoring, requiring separate tracking from sodium permanganate.
Which countries are the top exporters of sodium permanganate (HS 284169)?
In 2025, the top exporters of HS 284169 (the code used for sodium permanganate) in UN Comtrade data were China ($33M, 63% of world exports), Japan ($6.6M) and South Korea ($4.2M). World exports came to about $53M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of sodium permanganate (HS 284169)?
In 2025, the top importers of HS 284169 (the code used for sodium permanganate) in UN Comtrade data were South Korea ($31M, 55% of world imports), Japan ($5.4M) and the United States ($4.9M).
