Fertilizers, mineral or chemical; phosphatic, superphosphates, containing by weight 35% or more of diphosphorus pentaoxide (P2O5)

HS code 310311 covers a crucial category of fertilizers - phosphatic superphosphates. These fertilizers are essential for maintaining soil fertility and supporting global agricultural productivity. As a key input for the 020000 Agriculture, Forestry, and Fishing industry, the production and trade of these phosphatic fertilizers play a vital role in the broader economy.

Phosphatic superphosphates are typically produced through a chemical reaction between phosphate rock and sulfuric acid. The resulting slurry is then dried, granulated, and sometimes further processed to enhance its nutrient content and physical properties. Advanced production techniques may also involve additional processing steps, such as acidulation, to optimize the fertilizer's performance and suitability for various agricultural applications.

The primary inputs for the production of HS code 310311 fertilizers include phosphate rock, sulfuric acid, and various other mineral and chemical additives. Specialized production equipment, such as reactors, granulators, and drying systems, are also essential for the manufacturing process. Additionally, the industry relies on a reliable supply of energy sources, water, and skilled labor to ensure efficient and sustainable production.

The main output of HS code 310311 is phosphatic superphosphate fertilizer, which is widely used in the 020000 Agriculture, Forestry, and Fishing industry to enhance soil fertility and crop yields. These fertilizers may be further consumed by producers of 310310 Fertilizers, mineral or chemical; superphosphates, not elsewhere specified or included and other complex fertilizer blends, as they serve as key ingredients in the formulation of various agricultural inputs.
