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

HS code 310319 covers a range of phosphatic fertilizers that are essential for modern agriculture. These fertilizers play a crucial role in enhancing soil fertility and supporting the production of high-yielding crops, making them a vital component of the global food supply chain. The phosphatic fertilizers under this code are widely used across various agricultural sectors, contributing to the overall productivity and sustainability of the industry.

The production of phosphatic fertilizers covered under HS code 310319 typically involves the chemical processing of phosphate rock and other mineral resources. The key steps include mining and beneficiation of phosphate rock, followed by acidulation or thermal treatment to produce various phosphatic compounds, such as superphosphates. These processes are designed to extract and concentrate the phosphorus content, making it readily available for plant uptake.

The main inputs required for the production of HS code 310319 fertilizers include phosphate rock, sulfuric acid, and other mineral resources. Additionally, the industry relies on specialized equipment and machinery for mining, processing, and granulation of the final products. Energy sources, such as natural gas or electricity, are also essential for the various stages of production.

The primary outputs of HS code 310319 are various types of phosphatic fertilizers, including superphosphates and other phosphatic compounds. These fertilizers are then consumed by the 020100 Agriculture and Horticulture industry, where they are applied to crops and soil to enhance nutrient levels and improve agricultural productivity. The outputs of this industry also serve as inputs for the production of 310520 Mineral or chemical fertilizers containing the two fertilizing elements: phosphorus and potassium and 310530 (Diammonium hydrogenorthophosphate (diammonium phosphate)).
