Phosphorus

HS v2022 Code: 280470

About phosphorus

HS code 280470 covers the classification of phosphorus, a highly reactive non-metallic element that is essential for various industrial and agricultural applications. Phosphorus plays a crucial role in the global economy, with its widespread use in the production of fertilizers, detergents, food additives, and various other chemical compounds. As a key component in the phosphate industry, phosphorus is a vital resource for sustaining global food production and supporting the growth of numerous other industries.

Production process

Phosphorus is primarily produced through the thermal reduction of phosphate rock, a naturally occurring mineral. The production process involves heating the phosphate rock in the presence of carbon, typically in the form of coke or coal, to high temperatures. This process releases the phosphorus, which is then collected and purified for further use. The specific techniques employed may vary depending on the source of the phosphate rock and the desired purity of the final product.

Production inputs

The main inputs required for the production of phosphorus include phosphate rock, a source of carbon (such as coke or coal), and significant amounts of energy to power the high-temperature reduction process. Additionally, various other materials and equipment, such as furnaces, reactors, and purification systems, are necessary for the efficient and safe production of phosphorus.

Production outputs

The primary output of HS code 280470 is refined phosphorus, which can be used as a raw material for the production of a wide range of products. These include 280800 Phosphoric acid, 310510 Fertilizers, 340220 Detergents, and various other chemical compounds and intermediates. Phosphorus is an essential element for many industries, making it a crucial component in the global supply chain.
