HS Code 3104.30 – Fertilizers, mineral or chemical; potassic, potassium sulphate
HS code 3104.30 is the 6-digit subheading for fertilizers, mineral or chemical, potassic, potassium sulphate. It is used for sulphate of Potash (SOP), granular potassium sulphate, soluble potassium sulphate, standard potassium sulphate and chloride-free potassium fertilizer..
What HS 3104.30 covers
HS code 310430 covers potassium sulphate, another important mineral or chemical potassic fertilizer. Also known as Sulphate of Potash (SOP), it is highly valued for its dual nutrient benefits, providing both potassium and sulfur, both essential for plant growth. SOP is particularly preferred for chloride-sensitive crops (e.g., fruits, vegetables, tobacco) and in regions where soil salinity is a concern, as it has a lower salt index than MOP. International trade involves specialized chemical producers and mining companies, often from countries with specific mineral deposits or advanced processing capabilities. Major exporters include Germany, Belgium, and China. Importing countries are typically those with high-value agricultural sectors or specific soil conditions requiring chloride-free potassium. Key trade considerations include ensuring purity, managing potential caking, and adherence to quality standards for solubility and nutrient content.

Codes often confused with 3104.30
Common mistake. This code is often confused with potassium chloride (310420) if the specific chemical form is not accurately identified, or with industrial-grade potassium sulphate (283329) if its primary use as a fertilizer is not clearly established.
Top exporters and importers of HS code 310430, 2025
In 2025, the largest exporter of HS code 310430 in UN Comtrade data was Egypt, with 22% of world exports; the largest importer in UN Comtrade data was the United States, with 7.1% 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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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).
