HS Code 2830.10 – Sulphides; of sodium, whether or not chemically defined
HS code 2830.10 is the 6-digit subheading for sulphides, of sodium, whether or not chemically defined. It is used for sodium sulphide flakes, sodium sulphide solid, sodium hydrosulphide, sodium polysulphide solution and anhydrous sodium sulphide.
What HS 2830.10 covers
Sodium sulphides, covered by this HS code, are important inorganic chemicals widely traded internationally for their strong reducing properties and as a source of sulfur. They are primarily utilized in the leather tanning industry for dehairing hides, in mining for ore flotation, in the production of dyes, and in various chemical syntheses. Countries with significant leather industries, such as India, China, and Italy, are major importers. Mining nations and those with robust chemical manufacturing also import these compounds. Exporters are typically large chemical producers, including China, the USA, and Germany, which have the capacity for bulk production. Key trade considerations include ensuring proper packaging to prevent oxidation and moisture absorption, safe handling due to its corrosive nature and potential to release hydrogen sulfide gas, and compliance with environmental regulations regarding its use and disposal. The market is stable, driven by continuous industrial demand.

Common mistake. This code is specific to sodium sulphides and should not be confused with other metal sulphides (283090) or sulfates (2833xx), which have different chemical compositions and uses.
Top exporters and importers of HS code 283010, 2025
In 2025, the largest exporter of HS code 283010 in UN Comtrade data was China, with 69% of world exports; the largest importer in UN Comtrade data was the DR Congo, with about 11% of world imports. Iran did not report 2025 data, and its estimate from partner records misses its trade with other countries that did not report: in 2024 that was 7.2% of its exports here ($1.1M, CEPII BACI), so it may also belong among the top exporters.

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).
