About phosphates; (other than of mono- or disodium, other than of potassium or of calcium hydrogenorthophosphate (dicalcium phosphate) and excluding other phosphates of calcium), whether or not chemically defined

HS code 283529 covers a range of phosphate compounds, excluding certain specific types of phosphates. These phosphates are essential chemicals used in a variety of industries, from agriculture and food production to industrial applications and water treatment. As a key component in fertilizers, phosphates play a crucial role in global food security, while their diverse industrial applications make them an important part of the broader chemical industry.

Production process

Phosphates under HS code 283529 are typically produced through chemical reactions involving phosphoric acid and various other mineral compounds. The specific production techniques can vary depending on the target phosphate compound, but often involve neutralization, precipitation, and purification steps to isolate the desired product. Advanced processing methods like thermal decomposition may also be employed for certain phosphate types.

Production inputs

The main inputs required for the production of phosphates under HS code 283529 include phosphoric acid, various mineral salts and compounds (such as 283510 Phosphates; of mono- or disodium, 283525 Phosphates; of calcium, and 283526 (Phosphates; of calcium hydrogenorthophosphate (dicalcium phosphate))), as well as energy sources, water, and specialized production equipment.

Production outputs

The phosphate compounds covered under HS code 283529 have a wide range of applications, including use as fertilizers, water treatment chemicals, food additives, and industrial reagents. The outputs from this industry may be consumed by various other industries, such as 310520 Mineral or chemical fertilizers, nitrogenous-phosphatic, 281512 Phosphoric acid and polyphosphoric acids, and 282520 Quicklime, slaked lime and hydraulic lime, among others.
