Diphosphorus pentoxide; phosphoric acid and polyphosphoric acids

HS v2017 Code: 2809

About diphosphorus pentoxide; phosphoric acid and polyphosphoric acids

HS code 2809 covers the production and trade of diphosphorus pentoxide, phosphoric acid, and polyphosphoric acids. These chemicals are essential inputs for a wide range of industries, including agriculture, food processing, pharmaceuticals, and industrial manufacturing. As a key component in fertilizers, phosphoric acid plays a crucial role in global food production, making this industry vital to the broader economy.

Production process

The primary production method for diphosphorus pentoxide and phosphoric acid involves the reaction of phosphate rock with sulfuric acid. This process, known as the wet process, yields phosphoric acid as the main product, along with calcium sulfate as a by-product. Polyphosphoric acids are then produced through the further dehydration of phosphoric acid.

Production inputs

The main inputs for this industry include phosphate rock, sulfuric acid, and energy sources such as electricity or natural gas. Specialized equipment, such as reactors, evaporators, and filtration systems, are also essential for the production of these chemicals. Additionally, the industry relies on a skilled workforce with expertise in chemical processing and engineering.

Production outputs

The primary outputs of HS code 2809 are diphosphorus pentoxide, phosphoric acid, and polyphosphoric acids. These chemicals are then used as inputs for the production of 3105 Mineral or chemical fertilizers, nitrogenous, 2811 Other inorganic acids and other inorganic oxygen compounds of non-metals, and various other chemical products. The phosphoric acid produced under this code is a critical component in the manufacturing of 2836 (Carbonates; peroxocarbonates (percarbonates); commercial ammonium carbonate containing ammonium carbamate) and 2835 (Phosphinates (hypophosphites), phosphonates (phosphites) and phosphates; polyphosphates, whether or not chemically defined).
