HS Code 3102.29 – Fertilizers, mineral or chemical; nitrogenous, other than ammonium sulphate
HS code 3102.29 is the 6-digit subheading for fertilizers, mineral or chemical, nitrogenous, other than ammonium sulphate. It is used for calcium ammonium nitrate (CAN), ammonium chloride, sodium nitrate, calcium nitrate and ammonium thiosulphate.
What HS 3102.29 covers
This HS code serves as a residual category for other mineral or chemical nitrogenous fertilizers, excluding ammonium sulphate. This diverse group includes a variety of nitrogen-containing compounds used in agriculture, each with specific properties and applications. The trade involves a wide array of chemical and fertilizer manufacturers exporting specialized nitrogen sources to meet diverse crop and soil requirements globally. Importers range from large-scale agricultural operations to specialty crop growers. Key considerations include the specific chemical form of nitrogen (nitrate, ammoniacal, amide), release rates, and compatibility with different irrigation systems. The inclusion of these 'other' nitrogenous fertilizers under CBAM underscores the broad impact of carbon pricing on the entire nitrogen fertilizer sector, encouraging more efficient production and potentially influencing market competitiveness.

Codes often confused with 3102.29
Common mistake. This 'other' category can be tricky; products might be misclassified under more specific nitrogenous codes (310210, 310221, 310230) or even general chemical codes if their fertilizer use is not clear.
Top exporters and importers of HS code 310229, 2025
In 2025, the largest exporter of HS code 310229 in UN Comtrade data was Slovakia, with 24% of world exports; the largest importer in UN Comtrade data was Germany, 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).

What are common misclassifications for HS code 310229?
This 'other' category can be tricky; products might be misclassified under more specific nitrogenous codes (310210, 310221, 310230) or even general chemical codes if their fertilizer use is not clear.
Which countries are the top exporters of goods under HS code 310229?
In 2025, the top exporters of HS code 310229 in UN Comtrade data were Slovakia ($73M, 24% of world exports), Spain ($67M) and Greece ($43M).
