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

HS v2017 Code: 283525

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

HS code 283525 covers a range of phosphate-based compounds, including calcium hydrogenorthophosphate, also known as dicalcium phosphate. These materials play a crucial role in various industries, from agriculture and food production to pharmaceuticals and construction. As a key source of phosphorus, a vital nutrient for plant growth, the products under this code are essential for maintaining soil fertility and supporting global food security.

Production process

The production of the phosphate compounds covered by HS code 283525 typically involves the reaction of phosphoric acid with calcium-containing materials, such as limestone or calcium carbonate. This process can be carried out using various methods, including wet-process phosphoric acid production, thermal phosphoric acid production, or direct reaction of phosphoric acid with calcium sources. The resulting calcium hydrogenorthophosphate is then dried, milled, and processed to meet the specific requirements of different applications.

Production inputs

The main inputs required for the production of the materials under HS code 283525 include phosphoric acid, calcium-containing raw materials (e.g., limestone, calcium carbonate), and energy sources for the various processing steps. Additionally, specialized equipment, such as reactors, dryers, and milling machinery, is necessary to facilitate the production and processing of the final products.

Production outputs

The primary output of HS code 283525 is calcium hydrogenorthophosphate, or dicalcium phosphate, which finds widespread use in various industries. This material is commonly used as a feed additive in the 230110 Animal feed industry, as a nutrient source and flow agent. It is also used in the 300490 Pharmaceutical preparations industry as an excipient and in the 310390 Mineral or chemical fertilizers, phosphatic industry as a source of phosphorus for fertilizers.
