Phosphates; of calcium n.e.c. in item no. 2835.25, whether or not chemically defined

HS v2022 Code: 283526

About phosphates; of calcium n.e.c. in item no. 2835.25, whether or not chemically defined

HS code 283526 covers a range of calcium phosphate compounds that are widely used in various industries. These phosphates are essential raw materials for the production of fertilizers, animal feed supplements, and various chemical products. They play a crucial role in the global agricultural and industrial sectors, contributing to food security, environmental sustainability, and economic development.

Production process

Calcium phosphates are typically produced through chemical reactions between phosphoric acid and calcium-containing raw materials, such as limestone or calcium carbonate. The specific production techniques may involve processes like precipitation, filtration, drying, and sometimes further chemical modifications to obtain the desired phosphate compounds.

Production inputs

The main inputs required for the production of HS code 283526 phosphates include phosphoric acid, calcium-rich raw materials (e.g., limestone, calcium carbonate), and various chemical reagents. Additionally, specialized production equipment, such as reactors, filters, and drying systems, are necessary to facilitate the manufacturing process.

Production outputs

The primary outputs of HS code 283526 are various calcium phosphate compounds, including dicalcium phosphate, tricalcium phosphate, and other calcium phosphates not elsewhere classified. These outputs are widely used as 310000 fertilizers, 230800 animal feed supplements, and in the production of 283525 phosphates, other than of calcium.
