Phosphates; calcium hydrogenorthophosphate (dicalcium phosphate), whether or not chemically defined

HS v2022 Code: 283525

About phosphates; calcium hydrogenorthophosphate (dicalcium phosphate), whether or not chemically defined

HS code 283525 covers a group of phosphate compounds, with a focus on calcium hydrogenorthophosphate, also known as dicalcium phosphate. These phosphates are essential minerals that play a crucial role in various industries, from agriculture and animal feed to pharmaceuticals and food processing. As a key component in fertilizers, dicalcium phosphate helps to improve soil fertility and crop yields, contributing to global food security. Additionally, these phosphates find applications in dietary supplements, toothpaste, and other consumer products, making them an integral part of the broader chemical and manufacturing sectors.

Production process

The production of phosphates under HS code 283525 typically involves the reaction of phosphoric acid with calcium-containing compounds, such as limestone or calcium carbonate. This process, known as phosphoric acid neutralization, results in the formation of dicalcium phosphate. The resulting product can be further processed and refined to meet specific industry requirements, such as adjusting the particle size or purity level.

Production inputs

The main inputs required for the production of phosphates under HS code 283525 include phosphoric acid, calcium-containing raw materials (e.g., limestone, calcium carbonate), and various processing aids and reagents. Additionally, specialized equipment, such as reactors, filters, and drying systems, are necessary to facilitate the production and purification of the final phosphate compounds.

Production outputs

The primary output of HS code 283525 is dicalcium phosphate, which finds widespread use in various industries. This phosphate compound is commonly used as a feed additive in the 230110 animal feed industry, where it provides a source of calcium and phosphorus for livestock. It is also used in the 300490 pharmaceutical and 330499 cosmetic sectors, where it serves as an ingredient in dietary supplements, toothpaste, and other personal care products. Additionally, dicalcium phosphate is a key component in 310520 fertilizers, contributing to the growth and development of agricultural crops.
