HS Code 3103.19 – Fertilizers, mineral or chemical; phosphatic, superphosphates, other than containing by weight 35% or more of diphosphorus pentaoxide (P2O5)
HS code 3103.19 is the 6-digit subheading for fertilizers, mineral or chemical, phosphatic, superphosphates, other than containing by weight 35% or more of diphosphorus pentaoxide (P2O5). It is used for single superphosphate (SSP), ordinary superphosphate, granular SSP, powdered SSP and normal superphosphate..
What HS 3103.19 covers
This HS code encompasses superphosphates containing less than 35% by weight of diphosphorus pentaoxide (P2O5), primarily referring to ordinary or single superphosphate (SSP). These phosphatic fertilizers are vital for providing phosphorus to crops, essential for energy transfer, photosynthesis, and overall plant vigor. While less concentrated than TSP, SSP also supplies sulfur and calcium, which are beneficial micronutrients for many crops and soil types. International trade involves both large-scale fertilizer producers and regional manufacturers, often serving local or national agricultural markets. Exporters include countries with access to phosphate rock and sulfuric acid, while importers are typically nations with agricultural sectors requiring phosphorus inputs, particularly where sulfur and calcium are also needed. 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 3103.19
Common mistake. This code is differentiated from high-concentration superphosphates (310311) by its lower P2O5 content; misclassification can occur if the exact percentage is not accurately determined, impacting trade compliance.

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).
