HS Code 3102.90 – Fertilizers, mineral or chemical; nitrogenous, other kinds including mixtures not specified in the foregoing subheadings
HS code 3102.90 is the 6-digit subheading for fertilizers, mineral or chemical, nitrogenous, other kinds including mixtures not specified in the foregoing subheadings. It is used for slow-release nitrogen fertilizers, nitrogen stabilizers, urea formaldehyde fertilizers, isobutylidene diurea (IBDU) and crotonylidene diurea (CDU).
What HS 3102.90 covers
This HS code serves as a residual category for 'other' nitrogenous mineral or chemical fertilizers, including mixtures not specified in the preceding subheadings of 3102. This broad classification covers a diverse range of specialized nitrogen fertilizers, often tailored for specific crop needs, soil conditions, or application methods. Examples might include slow-release nitrogen fertilizers, nitrogen-stabilized products, or complex blends with other micronutrients where nitrogen is the primary component. International trade involves a mix of large chemical companies and niche manufacturers, exporting to countries with advanced agricultural practices or specific demands for specialty fertilizers. Importers range from developed agricultural markets to developing nations seeking to optimize crop yields. Key trade considerations include precise chemical composition, efficacy claims, regulatory approvals for novel formulations, and proper labeling to ensure safe and effective use.

Codes often confused with 3102.90
Common mistake. This 'other' category is prone to misclassification, as products could potentially fit into more specific nitrogenous fertilizer codes (310210-310280) if their primary component is overlooked, or even into multi-nutrient fertilizers (3105) if other nutrients are significant.
Top exporters and importers of HS code 310290, 2025
In 2025, the largest exporter of HS code 310290 in UN Comtrade data was Poland, with 11% of world exports; the largest importer in UN Comtrade data was Brazil, with 14% of world imports. Russia 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 54% of its exports here ($50M, 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 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 310290?
This 'other' category is prone to misclassification, as products could potentially fit into more specific nitrogenous fertilizer codes (310210-310280) if their primary component is overlooked, or even into multi-nutrient fertilizers (3105) if other nutrients are significant.
Which countries are the top exporters of goods under HS code 310290?
In 2025, the top exporters of HS code 310290 in UN Comtrade data were Poland ($87M, 11% of world exports), China ($82M) and the Netherlands ($79M). World exports came to about $809M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Russia 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 54% of its exports here ($50M, CEPII BACI), so it may also belong among the top exporters.
Which countries are the top importers of goods under HS code 310290?
In 2025, the top importers of HS code 310290 in UN Comtrade data were Brazil ($130M, 14% of world imports), the United States ($118M) and France ($63M). World imports came to about $963M, 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.
How is HS code 310290 structured?
HS code 310290 is a 6-digit subheading under the Harmonized System. The first 2 digits (31) identify the chapter, digits 3-4 (02) identify the heading, and digits 5-6 (90) specify the subheading. This code is standardized globally by the World Customs Organization.
What is the Brazil NCM code for HS code 310290?
In Brazil, HS code 310290 is NCM 3102.90.00. The last two digits are 00 because Brazil does not split this HS code further.
