Fertilizers, mineral or chemical; nitrogenous, ammonium sulphate

HS v2022 Code: 310221

About fertilizers, mineral or chemical; nitrogenous, ammonium sulphate

HS code 310221 covers ammonium sulphate, a widely used nitrogenous fertilizer that plays a crucial role in global agricultural production. As a key component of the nitrogen-phosphorus-potassium (NPK) fertilizer system, ammonium sulphate is essential for maintaining soil fertility and supporting the growth of a wide range of crops. This industry is a vital part of the broader agricultural supply chain, contributing to food security and economic development worldwide.

Production process

Ammonium sulphate is primarily produced through the reaction of ammonia and sulphuric acid. The process typically involves the neutralization of ammonia with sulphuric acid, followed by crystallization and drying to obtain the final product. Advanced production methods may also include granulation or prilling to improve the physical characteristics of the fertilizer for easier handling and application.

Production inputs

The main inputs for the production of ammonium sulphate include ammonia, sulphuric acid, and energy sources such as natural gas or coal. Specialized equipment, such as reactors, crystallizers, and drying systems, are also essential for the manufacturing process. Additionally, the industry relies on a skilled workforce with expertise in chemical processing and fertilizer production.

Production outputs

The primary output of HS code 310221 is ammonium sulphate, which is widely used as a nitrogen-rich fertilizer in agricultural applications. The fertilizer is often blended with other nutrients to create 310520 compound fertilizers or used as a standalone product. Ammonium sulphate may also be consumed by 310390 other fertilizer industries as a raw material for further processing or formulation.
