Salts; tungstates (wolframates)

HS v2022 Code: 284180

About salts; tungstates (wolframates)

HS code 284180 covers a range of salts and tungstates, which are important industrial chemicals with a wide variety of applications. Tungstates, also known as wolframates, are the salts of the element tungsten, which is a critical raw material for the production of various metal alloys, cutting tools, and electronic components. The salts and tungstates industry plays a crucial role in supporting the manufacturing, construction, and electronics sectors, contributing to the broader economic development.

Production process

The production of salts and tungstates typically involves chemical synthesis processes. Tungstates are commonly produced by reacting tungsten-containing ores or concentrates with alkaline solutions, such as sodium hydroxide or sodium carbonate, to form sodium tungstate. This sodium tungstate can then be further processed to obtain other tungstate compounds, such as ammonium or calcium tungstate, depending on the desired end product.

Production inputs

The main inputs required for the production of salts and tungstates include tungsten-bearing ores or concentrates, as well as various chemical reagents and energy sources. Specialized equipment, such as reactors, filtration systems, and drying units, are also essential for the manufacturing process. Additionally, the industry relies on a skilled workforce with expertise in chemical processing and materials science.

Production outputs

The salts and tungstates produced under HS code 284180 have a wide range of applications. Tungstates are used in the production of 810110 Tungsten and articles thereof, including tungsten carbide tools, high-speed steel, and various electronic components. They are also used in the manufacture of 282590 Inorganic chemicals n.e.c.; organic or inorganic compounds of precious metals, of rare-earth metals, of radioactive elements or of isotopes, such as catalysts and pigments. The salts produced under this code may find use in 284700 (Peroxoborates (perborates)) and other chemical formulations.
