HS Code 3103.11 – Fertilizers, mineral or chemical; phosphatic, superphosphates, containing by weight 35% or more of diphosphorus pentaoxide (P2O5)
HS code 3103.11 is the 6-digit subheading for fertilizers, mineral or chemical, phosphatic, superphosphates, containing by weight 35% or more of diphosphorus pentaoxide (P2O5). It is used for triple superphosphate (TSP), concentrated superphosphate, granular TSP, powdered TSP and high-analysis superphosphate..
What HS 3103.11 covers
HS code 310311 specifically covers superphosphates that contain 35% or more by weight of diphosphorus pentaoxide (P2O5). These are highly concentrated phosphatic fertilizers, crucial for promoting root development, flowering, and fruiting in plants. The high P2O5 content makes them efficient for transport and application, particularly in regions with intensive agriculture. Major players in this trade include large fertilizer manufacturers and mining companies that process phosphate rock into these concentrated forms. Exporters are often countries with significant phosphate reserves or advanced chemical processing capabilities, such as Morocco, China, and the USA. Importing countries are those with large agricultural sectors, like Brazil, India, and various European nations, seeking efficient phosphorus sources. Key trade considerations include ensuring the declared P2O5 content, managing potential heavy metal impurities, and adhering to environmental regulations regarding phosphate runoff.

Codes often confused with 3103.11
Common mistake. This code is distinct from other superphosphates (310319) based solely on its higher P2O5 concentration, and misclassification can occur if the exact percentage is not verified, leading to incorrect duties or product specifications.
Top exporters and importers of HS code 310311, 2025
In 2025, the largest exporter of HS code 310311 in UN Comtrade data was Morocco, with 82% of world exports; the largest importer in UN Comtrade data was Brazil, with 28% 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).
