HS Code 3102.50 – Fertilizers, mineral or chemical; nitrogenous, sodium nitrate
HS code 3102.50 is the 6-digit subheading for fertilizers, mineral or chemical, nitrogenous, sodium nitrate. It is used for sodium nitrate fertilizer, chilean nitrate, synthetic sodium nitrate, granular sodium nitrate and prilled sodium nitrate..
What HS 3102.50 covers
HS code 310250 specifically identifies mineral or chemical nitrogenous fertilizers in the form of sodium nitrate. While not as widely used as urea or ammonium nitrate, sodium nitrate holds a niche in agriculture, particularly for certain crops or soil types where its quick-release nitrogen and sodium content are beneficial. It's also used in organic farming as a natural source of nitrogen, though its synthetic counterparts fall under this code. International trade involves specialized chemical producers and distributors, with countries like Chile historically being a significant source due to natural deposits (Chilean saltpeter). Importers include nations with specific agricultural demands for this type of fertilizer, often smaller-scale or specialty crop producers. Key aspects of trade include ensuring purity, proper packaging to prevent moisture absorption, and adherence to agricultural input regulations.

Codes often confused with 3102.50
Common mistake. It can be confused with other nitrogenous fertilizers like urea (310210) or ammonium nitrate (310230) if the specific chemical composition of sodium nitrate is not precisely identified, leading to incorrect classification.
Top exporters and importers of HS code 310250, 2025
In 2025, the largest exporter of HS code 310250 in UN Comtrade data was Chile, with 33% of world exports; the largest importer in UN Comtrade data was the United States, with 16% 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. 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).
