Phosphates; of mono- or disodium, whether or not chemically defined

HS v2017 Code: 283522

About phosphates; of mono- or disodium, whether or not chemically defined

HS code 283522 covers phosphates of mono- or disodium, which are essential chemical compounds used in a wide range of industries. These phosphates play a crucial role in various applications, from detergents and cleaning products to food additives and agricultural fertilizers. As a key component in the global supply chain, the production and trade of these phosphates have significant economic implications, contributing to the broader chemical industry and supporting diverse sectors of the economy.

Production process

The production of phosphates of mono- or disodium typically involves the reaction of phosphoric acid with sodium hydroxide or sodium carbonate. This process results in the formation of the desired phosphate compounds, which are then purified and processed to meet specific industry requirements. Manufacturers may employ various techniques, such as crystallization, filtration, and drying, to ensure the quality and consistency of the final product.

Production inputs

The main inputs required for the production of HS code 283522 phosphates include phosphoric acid, sodium hydroxide or sodium carbonate, and various energy sources (e.g., electricity, steam) to power the manufacturing process. Additionally, specialized equipment, such as reactors, filtration systems, and drying units, are necessary to facilitate the production and purification of these phosphate compounds.

Production outputs

The primary outputs of HS code 283522 are phosphates of mono- or disodium, which find applications in a diverse range of industries. These phosphates are commonly used as detergent builders 340220 Detergents, food additives 210690 Food preparations, and agricultural fertilizers 310520 Mineral or chemical fertilizers. The outputs of this industry may also be consumed by manufacturers of 282520 Calcium phosphates, 283526 Polyphosphates, and other related chemical products.
