Fertilizers, mineral or chemical; nitrogenous, ammonium sulphate

HS v2017 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 the global agricultural industry. As a key source of nitrogen for plant growth, ammonium sulphate is an essential input for farmers and growers across a range of crops, contributing to improved crop yields and food security worldwide. This code sits within the broader 31 Fertilizers industry, which is a vital component of the global economy, supporting the production of the world's food supply.

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 granular or crystalline product. Advanced production techniques may also include granulation, compaction, or coating to improve the physical properties and handling characteristics of the fertilizer.

Production inputs

The main inputs required for the production of ammonium sulphate include ammonia, sulphuric acid, and energy sources such as natural gas or electricity. Specialized production equipment, including 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 then consumed by various 3102 Mineral or chemical fertilizers, nitrogenous and 3105 Mineral or chemical fertilizers containing two or three of the fertilizing elements nitrogen, phosphorus and potassium; other fertilizers codes. Ammonium sulphate is widely used as a nitrogen-rich fertilizer in a variety of agricultural applications, including field crops, vegetables, and specialty crops.
